partitionIn OKD version 4.14, you can install a cluster on Microsoft Azure Stack Hub by using infrastructure that you provide.
Several Azure Resource Manager (ARM) templates are provided to assist in completing these steps or to help model your own.
The steps for performing a user-provisioned infrastructure installation are provided as an example only. Installing a cluster with infrastructure you provide requires knowledge of the cloud provider and the installation process of OKD. Several ARM templates are provided to assist in completing these steps or to help model your own. You are also free to create the required resources through other methods; the templates are just an example. |
You reviewed details about the OKD installation and update processes.
You read the documentation on selecting a cluster installation method and preparing it for users.
You configured an Azure Stack Hub account to host the cluster.
You downloaded the Azure CLI and installed it on your computer. See Install the Azure CLI in the Azure documentation. The documentation below was tested using version 2.28.0
of the Azure CLI. Azure CLI commands might perform differently based on the version you use.
If you use a firewall and plan to use the Telemetry service, you configured the firewall to allow the sites that your cluster requires access to.
Be sure to also review this site list if you are configuring a proxy. |
Before you can install OKD, you must configure an Azure project to host it.
All Azure Stack Hub resources that are available through public endpoints are subject to resource name restrictions, and you cannot create resources that use certain terms. For a list of terms that Azure Stack Hub restricts, see Resolve reserved resource name errors in the Azure documentation. |
The OKD cluster uses a number of Microsoft Azure Stack Hub components, and the default Quota types in Azure Stack Hub affect your ability to install OKD clusters.
The following table summarizes the Azure Stack Hub components whose limits can impact your ability to install and run OKD clusters.
Component | Number of components required by default | Description | ||||||
---|---|---|---|---|---|---|---|---|
vCPU |
56 |
A default cluster requires 56 vCPUs, so you must increase the account limit. By default, each cluster creates the following instances:
Because the bootstrap, control plane, and worker machines use To deploy more worker nodes, enable autoscaling, deploy large workloads, or use a different instance type, you must further increase the vCPU limit for your account to ensure that your cluster can deploy the machines that you require. |
||||||
VNet |
1 |
Each default cluster requires one Virtual Network (VNet), which contains two subnets. |
||||||
Network interfaces |
7 |
Each default cluster requires seven network interfaces. If you create more machines or your deployed workloads create load balancers, your cluster uses more network interfaces. |
||||||
Network security groups |
2 |
Each cluster creates network security groups for each subnet in the VNet. The default cluster creates network security groups for the control plane and for the compute node subnets:
|
||||||
Network load balancers |
3 |
Each cluster creates the following load balancers:
If your applications create more Kubernetes |
||||||
Public IP addresses |
2 |
The public load balancer uses a public IP address. The bootstrap machine also uses a public IP address so that you can SSH into the machine to troubleshoot issues during installation. The IP address for the bootstrap node is used only during installation. |
||||||
Private IP addresses |
7 |
The internal load balancer, each of the three control plane machines, and each of the three worker machines each use a private IP address. |
To successfully install OKD on Azure Stack Hub, you must create DNS records in an Azure Stack Hub DNS zone. The DNS zone must be authoritative for the domain. To delegate a registrar’s DNS zone to Azure Stack Hub, see Microsoft’s documentation for Azure Stack Hub datacenter DNS integration.
You can view Azure’s DNS solution by visiting this example for creating DNS zones.
Because your cluster has limited access to automatic machine management when you use infrastructure that you provision, you must provide a mechanism for approving cluster certificate signing requests (CSRs) after installation. The kube-controller-manager
only approves the kubelet client CSRs. The machine-approver
cannot guarantee the validity of a serving certificate that is requested by using kubelet credentials because it cannot confirm that the correct machine issued the request. You must determine and implement a method of verifying the validity of the kubelet serving certificate requests and approving them.
Your Microsoft Azure Stack Hub account must have the following roles for the subscription that you use:
Owner
To set roles on the Azure portal, see the Manage access to resources in Azure Stack Hub with role-based access control in the Microsoft documentation.
Because OKD and its installation program create Microsoft Azure resources by using the Azure Resource Manager, you must create a service principal to represent it.
Install or update the Azure CLI.
Your Azure account has the required roles for the subscription that you use.
Register your environment:
$ az cloud register -n AzureStackCloud --endpoint-resource-manager <endpoint> (1)
1 | Specify the Azure Resource Manager endpoint, `https://management.<region>.<fqdn>/`. |
See the Microsoft documentation for details.
Set the active environment:
$ az cloud set -n AzureStackCloud
Update your environment configuration to use the specific API version for Azure Stack Hub:
$ az cloud update --profile 2019-03-01-hybrid
Log in to the Azure CLI:
$ az login
If you are in a multitenant environment, you must also supply the tenant ID.
If your Azure account uses subscriptions, ensure that you are using the right subscription:
View the list of available accounts and record the tenantId
value for the
subscription you want to use for your cluster:
$ az account list --refresh

Before you install OKD, download the installation file on the host you are using for installation.
You have a computer that runs Linux or macOS, with 500 MB of local disk space.
Download installer from https://github.com/openshift/okd/releases
The installation program creates several files on the computer that you use to install your cluster. You must keep the installation program and the files that the installation program creates after you finish installing the cluster. Both files are required to delete the cluster. |
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. To remove your cluster, complete the OKD uninstallation procedures for your specific cloud provider. |
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
$ tar -xvf openshift-install-linux.tar.gz
Download your installation pull secret from Red Hat OpenShift Cluster Manager. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OKD components.
Using a pull secret from Red Hat OpenShift Cluster Manager is not required. You can use a pull secret for another private registry. Or, if you do not need the cluster to pull images from a private registry, you can use {"auths":{"fake":{"auth":"aWQ6cGFzcwo="}}}
as the pull secret when prompted during the installation.
If you do not use the pull secret from Red Hat OpenShift Cluster Manager:
Red Hat Operators are not available.
The Telemetry and Insights operators do not send data to Red Hat.
Content from the Red Hat Container Catalog registry, such as image streams and Operators, are not available.
During an OKD installation, you can provide an SSH public key to the installation program. The key is passed to the Fedora CoreOS (FCOS) nodes through their Ignition config files and is used to authenticate SSH access to the nodes. The key is added to the ~/.ssh/authorized_keys
list for the core
user on each node, which enables password-less authentication.
After the key is passed to the nodes, you can use the key pair to SSH in to the FCOS nodes as the user core
. To access the nodes through SSH, the private key identity must be managed by SSH for your local user.
If you want to SSH in to your cluster nodes to perform installation debugging or disaster recovery, you must provide the SSH public key during the installation process. The ./openshift-install gather
command also requires the SSH public key to be in place on the cluster nodes.
Do not skip this procedure in production environments, where disaster recovery and debugging is required. |
You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs. |
On clusters running Fedora CoreOS (FCOS), the SSH keys specified in the Ignition config files are written to the |
If you do not have an existing SSH key pair on your local machine to use for authentication onto your cluster nodes, create one. For example, on a computer that uses a Linux operating system, run the following command:
$ ssh-keygen -t ed25519 -N '' -f <path>/<file_name> (1)
1 | Specify the path and file name, such as ~/.ssh/id_ed25519 , of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory. |
If you plan to install an OKD cluster that uses the Fedora cryptographic libraries that have been submitted to NIST for FIPS 140-2/140-3 Validation on only the |
View the public SSH key:
$ cat <path>/<file_name>.pub
For example, run the following to view the ~/.ssh/id_ed25519.pub
public key:
$ cat ~/.ssh/id_ed25519.pub
Add the SSH private key identity to the SSH agent for your local user, if it has not already been added. SSH agent management of the key is required for password-less SSH authentication onto your cluster nodes, or if you want to use the ./openshift-install gather
command.
On some distributions, default SSH private key identities such as |
If the ssh-agent
process is not already running for your local user, start it as a background task:
$ eval "$(ssh-agent -s)"
Agent pid 31874
If your cluster is in FIPS mode, only use FIPS-compliant algorithms to generate the SSH key. The key must be either RSA or ECDSA. |
Add your SSH private key to the ssh-agent
:
$ ssh-add <path>/<file_name> (1)
1 | Specify the path and file name for your SSH private key, such as ~/.ssh/id_ed25519 |
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
When you install OKD, provide the SSH public key to the installation program.
To install OKD on Microsoft Azure Stack Hub using user-provisioned infrastructure, you must generate the files that the installation program needs to deploy your cluster and modify them so that the cluster creates only the machines that it will use. You manually create the install-config.yaml
file, and then generate and customize the Kubernetes manifests and Ignition config files. You also have the option to first set up a separate var
partition during the preparation phases of installation.
You have an SSH public key on your local machine to provide to the installation program. The key will be used for SSH authentication onto your cluster nodes for debugging and disaster recovery.
You have obtained the OKD installation program and the pull secret for your cluster.
Create an installation directory to store your required installation assets in:
$ mkdir <installation_directory>
You must create a directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OKD version. |
Customize the sample install-config.yaml
file template that is provided and save
it in the <installation_directory>
.
You must name this configuration file |
Make the following modifications for Azure Stack Hub:
Set the replicas
parameter to 0
for the compute
pool:
compute:
- hyperthreading: Enabled
name: worker
platform: {}
replicas: 0 (1)
1 | Set to 0 . |
The compute machines will be provisioned manually later.
Update the platform.azure
section of the install-config.yaml
file to configure your Azure Stack Hub configuration:
platform:
azure:
armEndpoint: <azurestack_arm_endpoint> (1)
baseDomainResourceGroupName: <resource_group> (2)
cloudName: AzureStackCloud (3)
region: <azurestack_region> (4)
1 | Specify the Azure Resource Manager endpoint of your Azure Stack Hub environment, like https://management.local.azurestack.external . |
2 | Specify the name of the resource group that contains the DNS zone for your base domain. |
3 | Specify the Azure Stack Hub environment, which is used to configure the Azure SDK with the appropriate Azure API endpoints. |
4 | Specify the name of your Azure Stack Hub region. |

You must export a common set of variables that are used with the provided Azure Resource Manager (ARM) templates used to assist in completing a user-provided infrastructure install on Microsoft Azure Stack Hub.
Specific ARM templates can also require additional exported variables, which are detailed in their related procedures. |
Obtain the OKD installation program and the pull secret for your cluster.
Export common variables found in the install-config.yaml
to be used by the
provided ARM templates:
$ export CLUSTER_NAME=<cluster_name>(1)
$ export AZURE_REGION=<azure_region>(2)
$ export SSH_KEY=<ssh_key>(3)
$ export BASE_DOMAIN=<base_domain>(4)
$ export BASE_DOMAIN_RESOURCE_GROUP=<base_domain_resource_group>(5)
1 | The value of the .metadata.name attribute from the install-config.yaml file. |
2 | The region to deploy the cluster into. This is the value of the .platform.azure.region attribute from the install-config.yaml file. |
3 | The SSH RSA public key file as a string. You must enclose the SSH key in quotes since it contains spaces. This is the value of the .sshKey attribute from the install-config.yaml file. |
4 | The base domain to deploy the cluster to. The base domain corresponds to the DNS zone that you created for your cluster. This is the value of the .baseDomain attribute from the install-config.yaml file. |
5 | The resource group where the DNS zone exists. This is the value of the .platform.azure.baseDomainResourceGroupName attribute from the install-config.yaml file. |
For example:
$ export CLUSTER_NAME=test-cluster
$ export AZURE_REGION=centralus
$ export SSH_KEY="ssh-rsa xxx/xxx/xxx= user@email.com"
$ export BASE_DOMAIN=example.com
$ export BASE_DOMAIN_RESOURCE_GROUP=ocp-cluster
Export the kubeadmin credentials:
$ export KUBECONFIG=<installation_directory>/auth/kubeconfig (1)
1 | For <installation_directory> , specify the path to the directory that you stored the installation files in. |
Because you must modify some cluster definition files and manually start the cluster machines, you must generate the Kubernetes manifest and Ignition config files that the cluster needs to configure the machines.
The installation configuration file transforms into the Kubernetes manifests. The manifests wrap into the Ignition configuration files, which are later used to configure the cluster machines.
|
You obtained the OKD installation program.
You created the install-config.yaml
installation configuration file.
Change to the directory that contains the OKD installation program and generate the Kubernetes manifests for the cluster:
$ ./openshift-install create manifests --dir <installation_directory> (1)
1 | For <installation_directory> , specify the installation directory that
contains the install-config.yaml file you created. |
Remove the Kubernetes manifest files that define the control plane machines:
$ rm -f <installation_directory>/openshift/99_openshift-cluster-api_master-machines-*.yaml
By removing these files, you prevent the cluster from automatically generating control plane machines.
Remove the Kubernetes manifest files that define the control plane machine set:
$ rm -f <installation_directory>/openshift/99_openshift-machine-api_master-control-plane-machine-set.yaml
Remove the Kubernetes manifest files that define the worker machines:
$ rm -f <installation_directory>/openshift/99_openshift-cluster-api_worker-machineset-*.yaml
If you disabled the |
Because you create and manage the worker machines yourself, you do not need to initialize these machines.
Check that the mastersSchedulable
parameter in the <installation_directory>/manifests/cluster-scheduler-02-config.yml
Kubernetes manifest file is set to false
. This setting prevents pods from being scheduled on the control plane machines:
Open the <installation_directory>/manifests/cluster-scheduler-02-config.yml
file.
Locate the mastersSchedulable
parameter and ensure that it is set to false
.
Save and exit the file.
Optional: If you do not want
the Ingress Operator
to create DNS records on your behalf, remove the privateZone
and publicZone
sections from the <installation_directory>/manifests/cluster-dns-02-config.yml
DNS configuration file:
apiVersion: config.openshift.io/v1
kind: DNS
metadata:
creationTimestamp: null
name: cluster
spec:
baseDomain: example.openshift.com
privateZone: (1)
id: mycluster-100419-private-zone
publicZone: (1)
id: example.openshift.com
status: {}
1 | Remove this section completely. |
If you do so, you must add ingress DNS records manually in a later step.
Optional: If your Azure Stack Hub environment uses an internal certificate authority (CA), you must update the .spec.trustedCA.name
field in the <installation_directory>/manifests/cluster-proxy-01-config.yaml
file to use user-ca-bundle
:
...
spec:
trustedCA:
name: user-ca-bundle
...
Later, you must update your bootstrap ignition to include the CA.
When configuring Azure on user-provisioned infrastructure, you must export some common variables defined in the manifest files to use later in the Azure Resource Manager (ARM) templates:
Export the infrastructure ID by using the following command:
$ export INFRA_ID=<infra_id> (1)
1 | The OKD cluster has been assigned an identifier (INFRA_ID ) in the form of <cluster_name>-<random_string> . This will be used as the base name for most resources created using the provided ARM templates. This is the value of the .status.infrastructureName attribute from the manifests/cluster-infrastructure-02-config.yml file. |
Export the resource group by using the following command:
$ export RESOURCE_GROUP=<resource_group> (1)
1 | All resources created in this Azure deployment exists as part of a resource group. The resource group name is also based on the INFRA_ID , in the form of <cluster_name>-<random_string>-rg . This is the value of the .status.platformStatus.azure.resourceGroupName attribute from the manifests/cluster-infrastructure-02-config.yml file. |
Manually create your cloud credentials.
From the directory that contains the installation program, obtain details of the OKD release image that your openshift-install
binary is built to use:
$ openshift-install version
release image quay.io/openshift-release-dev/ocp-release:4.y.z-x86_64
Set a $RELEASE_IMAGE
variable with the release image from your installation file by running the following command:
$ RELEASE_IMAGE=$(./openshift-install version | awk '/release image/ {print $3}')
Extract the list of CredentialsRequest
custom resources (CRs) from the OKD release image by running the following command:
$ oc adm release extract \
--from=$RELEASE_IMAGE \
--credentials-requests \
--included \(1)
--install-config=<path_to_directory_with_installation_configuration>/install-config.yaml \(2)
--to=<path_to_directory_for_credentials_requests> (3)
1 | The --included parameter includes only the manifests that your specific cluster configuration requires. |
2 | Specify the location of the install-config.yaml file. |
3 | Specify the path to the directory where you want to store the CredentialsRequest objects. If the specified directory does not exist, this command creates it. |
This command creates a YAML file for each CredentialsRequest
object.

partition or a subdirectory of /var
. For example:
/var/lib/containers
: Holds container-related content that can grow as more images and containers are added to a system.
/var/lib/etcd
: Holds data that you might want to keep separate for purposes such as performance optimization of etcd storage.
/var
: Holds data that you might want to keep separate for purposes such as auditing.
Storing the contents of a /var
directory separately makes it easier to grow storage for those areas as needed and reinstall OKD at a later date and keep that data intact. With this method, you will not have to pull all your containers again, nor will you have to copy massive log files when you update systems.
Because /var
must be in place before a fresh installation of Fedora CoreOS (FCOS), the following procedure sets up the separate /var
partition by creating a machine config manifest that is inserted during the openshift-install
preparation phases of an OKD installation.
If you follow the steps to create a separate |
Create a directory to hold the OKD installation files:
$ mkdir $HOME/clusterconfig
Run openshift-install
to create a set of files in the manifest
and openshift
subdirectories. Answer the system questions as you are prompted:
$ openshift-install create manifests --dir $HOME/clusterconfig
? SSH Public Key ...
INFO Credentials loaded from the "myprofile" profile in file "/home/myuser/.aws/credentials"
INFO Consuming Install Config from target directory
INFO Manifests created in: $HOME/clusterconfig/manifests and $HOME/clusterconfig/openshift
Optional: Confirm that the installation program created manifests in the clusterconfig/openshift
directory:
$ ls $HOME/clusterconfig/openshift/
99_kubeadmin-password-secret.yaml
99_openshift-cluster-api_master-machines-0.yaml
99_openshift-cluster-api_master-machines-1.yaml
99_openshift-cluster-api_master-machines-2.yaml
...
Create a Butane config that configures the additional partition. For example, name the file $HOME/clusterconfig/98-var-partition.bu
, change the disk device name to the name of the storage device on the worker
systems, and set the storage size as appropriate. This example places the /var
directory on a separate partition:
variant: openshift
version: 4.14.0
metadata:
labels:
machineconfiguration.openshift.io/role: worker
name: 98-var-partition
storage:
disks:
- device: /dev/disk/by-id/<device_name> (1)
partitions:
- label: var
start_mib: <partition_start_offset> (2)
size_mib: <partition_size> (3)
number: 5
filesystems:
- device: /dev/disk/by-partlabel/var
path: /var
format: xfs
mount_options: [defaults, prjquota] (4)
with_mount_unit: true
1 | The storage device name of the disk that you want to partition. |
2 | When adding a data partition to the boot disk, a minimum value of 25000 MiB (Mebibytes) is recommended. The root file system is automatically resized to fill all available space up to the specified offset. If no value is specified, or if the specified value is smaller than the recommended minimum, the resulting root file system will be too small, and future reinstalls of FCOS might overwrite the beginning of the data partition. |
3 | The size of the data partition in mebibytes. |
4 | The prjquota mount option must be enabled for filesystems used for container storage. |
When creating a separate |
Create a manifest from the Butane config and save it to the clusterconfig/openshift
directory. For example, run the following command:
$ butane $HOME/clusterconfig/98-var-partition.bu -o $HOME/clusterconfig/openshift/98-var-partition.yaml
Run openshift-install
again to create Ignition configs from a set of files in the manifest
and openshift
subdirectories:
$ openshift-install create ignition-configs --dir $HOME/clusterconfig
$ ls $HOME/clusterconfig/
auth bootstrap.ign master.ign metadata.json worker.ign
Now you can use the Ignition config files as input to the installation procedures to install Fedora CoreOS (FCOS) systems.
You must create a Microsoft Azure resource group. This is used during the installation of your OKD cluster on Azure Stack Hub.
Configure an Azure account.
Generate the Ignition config files for your cluster.
Create the resource group in a supported Azure region:
$ az group create --name ${RESOURCE_GROUP} --location ${AZURE_REGION}
The Azure client does not support deployments based on files existing locally. You must copy and store the FCOS virtual hard disk (VHD) cluster image and bootstrap Ignition config file in a storage container so they are accessible during deployment.
Configure an Azure account.
Generate the Ignition config files for your cluster.
Create an Azure storage account to store the VHD cluster image:
$ az storage account create -g ${RESOURCE_GROUP} --location ${AZURE_REGION} --name ${CLUSTER_NAME}sa --kind Storage --sku Standard_LRS
The Azure storage account name must be between 3 and 24 characters in length and
use numbers and lower-case letters only. If your |
Export the storage account key as an environment variable:
$ export ACCOUNT_KEY=`az storage account keys list -g ${RESOURCE_GROUP} --account-name ${CLUSTER_NAME}sa --query "[0].value" -o tsv`
Export the URL of the FCOS VHD to an environment variable:
$ export COMPRESSED_VHD_URL=$(openshift-install coreos print-stream-json | jq -r '.architectures.x86_64.artifacts.azurestack.formats."vhd.gz".disk.location')
The FCOS images might not change with every release of OKD. You must specify an image with the highest version that is less than or equal to the OKD version that you install. Use the image version that matches your OKD version if it is available. |
Create the storage container for the VHD:
$ az storage container create --name vhd --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY}
Download the compressed FCOS VHD file locally:
$ curl -O -L ${COMPRESSED_VHD_URL}
Decompress the VHD file.
The decompressed VHD file is approximately 16 GB, so be sure that your host system has 16 GB of free space available. You can delete the VHD file after you upload it. |
Copy the local VHD to a blob:
$ az storage blob upload --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} -c vhd -n "rhcos.vhd" -f rhcos-<rhcos_version>-azurestack.x86_64.vhd
Create a blob storage container and upload the generated bootstrap.ign
file:
$ az storage container create --name files --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY}
$ az storage blob upload --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} -c "files" -f "<installation_directory>/bootstrap.ign" -n "bootstrap.ign"
DNS records are required for clusters that use user-provisioned infrastructure. You should choose the DNS strategy that fits your scenario.
For this example, Azure Stack Hub’s datacenter DNS integration is used, so you will create a DNS zone.
The DNS zone is not required to exist in the same resource group as the cluster deployment and might already exist in your organization for the desired base domain. If that is the case, you can skip creating the DNS zone; be sure the installation config you generated earlier reflects that scenario. |
Configure an Azure account.
Generate the Ignition config files for your cluster.
Create the new DNS zone in the resource group exported in the
BASE_DOMAIN_RESOURCE_GROUP
environment variable:
$ az network dns zone create -g ${BASE_DOMAIN_RESOURCE_GROUP} -n ${CLUSTER_NAME}.${BASE_DOMAIN}
You can skip this step if you are using a DNS zone that already exists.
You can learn more about configuring a DNS zone in Azure Stack Hub by visiting that section.
You must create a virtual network (VNet) in Microsoft Azure Stack Hub for your OKD cluster to use. You can customize the VNet to meet your requirements. One way to create the VNet is to modify the provided Azure Resource Manager (ARM) template.
If you do not use the provided ARM template to create your Azure Stack Hub infrastructure, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs. |

All the Fedora CoreOS (FCOS) machines require networking to be configured in initramfs
during boot
to fetch their Ignition config files.
You must configure the network connectivity between machines to allow OKD cluster components to communicate. Each machine must be able to resolve the hostnames of all other machines in the cluster.
This section provides details about the ports that are required.
In connected OKD environments, all nodes are required to have internet access to pull images for platform containers and provide telemetry data to Red Hat. |

You must configure networking and load balancing in Microsoft Azure Stack Hub for your OKD cluster to use. One way to create these components is to modify the provided Azure Resource Manager (ARM) template.
Load balancing requires the following DNS records:
An api
DNS record for the API public load balancer in the DNS zone.
An api-int
DNS record for the API internal load balancer in the DNS zone.
If you do not use the provided ARM template to create your Azure Stack Hub infrastructure, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs. |
Configure an Azure account.
Generate the Ignition config files for your cluster.
Create and configure a VNet and associated subnets in Azure Stack Hub.
Copy the template from the ARM template for the network and load balancers
section of this topic and save it as 03_infra.json
in your cluster’s installation directory. This
template describes the networking and load balancing objects that your cluster
requires.
Create the deployment by using the az
CLI:
$ az deployment group create -g ${RESOURCE_GROUP} \
--template-file "<installation_directory>/03_infra.json" \
--parameters baseName="${INFRA_ID}"(1)
1 | The base name to be used in resource names; this is usually the cluster’s infrastructure ID. |
Create an api
DNS record and an api-int
DNS record. When creating the API DNS records, the ${BASE_DOMAIN_RESOURCE_GROUP}
variable must point to the resource group where the DNS zone exists.
Export the following variable:
$ export PUBLIC_IP=`az network public-ip list -g ${RESOURCE_GROUP} --query "[?name=='${INFRA_ID}-master-pip'] | [0].ipAddress" -o tsv`
Export the following variable:
$ export PRIVATE_IP=`az network lb frontend-ip show -g "$RESOURCE_GROUP" --lb-name "${INFRA_ID}-internal" -n internal-lb-ip --query "privateIpAddress" -o tsv`
Create the api
DNS record in a new DNS zone:
$ az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z ${CLUSTER_NAME}.${BASE_DOMAIN} -n api -a ${PUBLIC_IP} --ttl 60
If you are adding the cluster to an existing DNS zone, you can create the api
DNS record in it instead:
$ az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z ${BASE_DOMAIN} -n api.${CLUSTER_NAME} -a ${PUBLIC_IP} --ttl 60
Create the api-int
DNS record in a new DNS zone:
$ az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z "${CLUSTER_NAME}.${BASE_DOMAIN}" -n api-int -a ${PRIVATE_IP} --ttl 60
If you are adding the cluster to an existing DNS zone, you can create the api-int
DNS
record in it instead:
$ az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z ${BASE_DOMAIN} -n api-int.${CLUSTER_NAME} -a ${PRIVATE_IP} --ttl 60

You must create the bootstrap machine in Microsoft Azure Stack Hub to use during OKD cluster initialization. One way to create this machine is to modify the provided Azure Resource Manager (ARM) template.
If you do not use the provided ARM template to create your bootstrap machine, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs. |
Configure an Azure account.
Generate the Ignition config files for your cluster.
Create and configure a VNet and associated subnets in Azure Stack Hub.
Create and configure networking and load balancers in Azure Stack Hub.
Create control plane and compute roles.
Copy the template from the ARM template for the bootstrap machine section of
this topic and save it as 04_bootstrap.json
in your cluster’s installation directory. This template
describes the bootstrap machine that your cluster requires.
Export the bootstrap URL variable:
$ bootstrap_url_expiry=`date -u -d "10 hours" '+%Y-%m-%dT%H:%MZ'`
$ export BOOTSTRAP_URL=`az storage blob generate-sas -c 'files' -n 'bootstrap.ign' --https-only --full-uri --permissions r --expiry $bootstrap_url_expiry --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} -o tsv`
Export the bootstrap ignition variable:
If your environment uses a public certificate authority (CA), run this command:
$ export BOOTSTRAP_IGNITION=`jq -rcnM --arg v "3.2.0" --arg url ${BOOTSTRAP_URL} '{ignition:{version:$v,config:{replace:{source:$url}}}}' | base64 | tr -d '\n'`
If your environment uses an internal CA, you must add your PEM encoded bundle to the bootstrap ignition stub so that your bootstrap virtual machine can pull the bootstrap ignition from the storage account. Run the following commands, which assume your CA is in a file called CA.pem
:
$ export CA="data:text/plain;charset=utf-8;base64,$(cat CA.pem |base64 |tr -d '\n')"
$ export BOOTSTRAP_IGNITION=`jq -rcnM --arg v "3.2.0" --arg url "$BOOTSTRAP_URL" --arg cert "$CA" '{ignition:{version:$v,security:{tls:{certificateAuthorities:[{source:$cert}]}},config:{replace:{source:$url}}}}' | base64 | tr -d '\n'`
Create the deployment by using the az
CLI:
$ az deployment group create --verbose -g ${RESOURCE_GROUP} \

You must create the control plane machines in Microsoft Azure Stack Hub for your cluster to use. One way to create these machines is to modify the provided Azure Resource Manager (ARM) template.
If you do not use the provided ARM template to create your control plane machines, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, consider contacting Red Hat support with your installation logs.
Configure an Azure account.
Generate the Ignition config files for your cluster.
Create and configure a VNet and associated subnets in Azure Stack Hub.
Create and configure networking and load balancers in Azure Stack Hub.
Create control plane and compute roles.
Create the bootstrap machine.
Copy the template from the ARM template for control plane machines
section of this topic and save it as 05_masters.json
in your cluster’s installation directory.
This template describes the control plane machines that your cluster requires.
Export the following variable needed by the control plane machine deployment:
$ export MASTER_IGNITION=`cat <installation_directory>/master.ign | base64 | tr -d '\n'`
Create the deployment by using the az
CLI:
$ az deployment group create -g ${RESOURCE_GROUP} \
--template-file "<installation_directory>/05_masters.json" \
--parameters masterIgnition="${MASTER_IGNITION}" \ (1)
--parameters baseName="${INFRA_ID}" \ (2)
--parameters diagnosticsStorageAccountName="${CLUSTER_NAME}sa" (3)
1 | The Ignition content for the control plane nodes (also known as the master nodes). |
2 | The base name to be used in resource names; this is usually the cluster’s infrastructure ID. |
3 | The name of the storage account for your cluster. |
You can use the following Azure Resource Manager (ARM) template to deploy the control plane machines that you need for your OKD cluster:

After you create all of the required infrastructure in Microsoft Azure Stack Hub, wait for the bootstrap process to complete on the machines that you provisioned by using the Ignition config files that you generated with the installation program.
Configure an Azure account.
Generate the Ignition config files for your cluster.
Create and configure a VNet and associated subnets in Azure Stack Hub.
Create and configure networking and load balancers in Azure Stack Hub.
Create control plane and compute roles.
Create the bootstrap machine.
Create the control plane machines.
Change to the directory that contains the installation program and run the following command:
$ ./openshift-install wait-for bootstrap-complete --dir <installation_directory> \ (1)
--log-level info (2)
1 | For <installation_directory> , specify the path to the directory that you
stored the installation files in. |
2 | To view different installation details, specify warn , debug , or
error instead of info . |
If the command exits without a FATAL
warning, your production control plane
has initialized.
Delete the bootstrap resources:
$ az network nsg rule delete -g ${RESOURCE_GROUP} --nsg-name ${INFRA_ID}-nsg --name bootstrap_ssh_in
$ az vm stop -g ${RESOURCE_GROUP} --name ${INFRA_ID}-bootstrap
$ az vm deallocate -g ${RESOURCE_GROUP} --name ${INFRA_ID}-bootstrap
$ az vm delete -g ${RESOURCE_GROUP} --name ${INFRA_ID}-bootstrap --yes
$ az disk delete -g ${RESOURCE_GROUP} --name ${INFRA_ID}-bootstrap_OSDisk --no-wait --yes
$ az network nic delete -g ${RESOURCE_GROUP} --name ${INFRA_ID}-bootstrap-nic --no-wait
$ az storage blob delete --account-key ${ACCOUNT_KEY} --account-name ${CLUSTER_NAME}sa --container-name files --name bootstrap.ign
$ az network public-ip delete -g ${RESOURCE_GROUP} --name ${INFRA_ID}-bootstrap-ssh-pip
If you do not delete the bootstrap server, installation may not succeed due to API traffic being routed to the bootstrap server. |
You can create worker machines in Microsoft Azure Stack Hub for your cluster to use by launching individual instances discretely or by automated processes outside the cluster, such as auto scaling groups. You can also take advantage of the built-in cluster scaling mechanisms and the machine API in OKD.
In this example, you manually launch one instance by using the Azure Resource
Manager (ARM) template. Additional instances can be launched by including
additional resources of type 06_workers.json
in the file.
If you do not use the provided ARM template to create your control plane machines, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, consider contacting Red Hat support with your installation logs.

You can log in to your cluster as a default system user by exporting the cluster kubeconfig
file.
The kubeconfig
file contains information about the cluster that is used by the CLI to connect a client to the correct cluster and API server.
The file is specific to a cluster and is created during OKD installation.

When you add machines to a cluster, two pending certificate signing requests (CSRs) are generated for each machine that you added. You must confirm that these CSRs are approved or, if necessary, approve them yourself. The client requests must be approved first, followed by the server requests.
You added machines to your cluster.
Confirm that the cluster recognizes the machines:
$ oc get nodes
NAME STATUS ROLES AGE VERSION
master-0 Ready master 63m v1.27.3
master-1 Ready master 63m v1.27.3
master-2 Ready master 64m v1.27.3
The output lists all of the machines that you created.
The preceding output might not include the compute nodes, also known as worker nodes, until some CSRs are approved. |
Review the pending CSRs and ensure that you see the client requests with the Pending
or Approved
status for each machine that you added to the cluster:
$ oc get csr
NAME AGE REQUESTOR CONDITION
csr-8b2br 15m system:serviceaccount:openshift-machine-config-operator:node-bootstrapper Pending
csr-8vnps 15m system:serviceaccount:openshift-machine-config-operator:node-bootstrapper Pending
...
In this example, two machines are joining the cluster. You might see more approved CSRs in the list.
If the CSRs were not approved, after all of the pending CSRs for the machines you added are in Pending
status, approve the CSRs for your cluster machines:
Because the CSRs rotate automatically, approve your CSRs within an hour of adding the machines to the cluster. If you do not approve them within an hour, the certificates will rotate, and more than two certificates will be present for each node. You must approve all of these certificates. After the client CSR is approved, the Kubelet creates a secondary CSR for the serving certificate, which requires manual approval. Then, subsequent serving certificate renewal requests are automatically approved by the |
For clusters running on platforms that are not machine API enabled, such as bare metal and other user-provisioned infrastructure, you must implement a method of automatically approving the kubelet serving certificate requests (CSRs). If a request is not approved, then the |
To approve them individually, run the following command for each valid CSR:
$ oc adm certificate approve <csr_name> (1)

Now that your client requests are approved, you must review the server requests for each machine that you added to the cluster:
$ oc get csr
NAME AGE REQUESTOR CONDITION
csr-bfd72 5m26s system:node:ip-10-0-50-126.us-east-2.compute.internal Pending
csr-c57lv 5m26s system:node:ip-10-0-95-157.us-east-2.compute.internal Pending
...
If the remaining CSRs are not approved, and are in the Pending
status, approve the CSRs for your cluster machines:
To approve them individually, run the following command for each valid CSR:
$ oc adm certificate approve <csr_name> (1)
1 | <csr_name> is the name of a CSR from the list of current CSRs. |
To approve all pending CSRs, run the following command:
$ oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs oc adm certificate approve
After all client and server CSRs have been approved, the machines have the Ready
status. Verify this by running the following command:
$ oc get nodes
NAME STATUS ROLES AGE VERSION
master-0 Ready master 73m v1.27.3
master-1 Ready master 73m v1.27.3
master-2 Ready master 74m v1.27.3
worker-0 Ready worker 11m v1.27.3
worker-1 Ready worker 11m v1.27.3
It can take a few minutes after approval of the server CSRs for the machines to transition to the |

If you removed the DNS Zone configuration when creating Kubernetes manifests and
generating Ignition configs, you must manually create DNS records that point at
the Ingress load balancer. You can create either a wildcard
*.apps.{baseDomain}.
or specific records. You can use A, CNAME, and other
records per your requirements.
You deployed an OKD cluster on Microsoft Azure Stack Hub by using infrastructure that you provisioned.
Install the OpenShift CLI (oc
).
Install or update the Azure CLI.
Confirm the Ingress router has created a load balancer and populated the
EXTERNAL-IP
field:
$ oc -n openshift-ingress get service router-default
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
router-default LoadBalancer 172.30.20.10 35.130.120.110 80:32288/TCP,443:31215/TCP 20
Export the Ingress router IP as a variable:
$ export PUBLIC_IP_ROUTER=`oc -n openshift-ingress get service router-default --no-headers | awk '{print $4}'`
Add a *.apps
record to the DNS zone.
If you are adding this cluster to a new DNS zone, run:
$ az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z ${CLUSTER_NAME}.${BASE_DOMAIN} -n *.apps -a ${PUBLIC_IP_ROUTER} --ttl 300
If you are adding this cluster to an already existing DNS zone, run:
$ az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z ${BASE_DOMAIN} -n *.apps.${CLUSTER_NAME} -a ${PUBLIC_IP_ROUTER} --ttl 300
If you prefer to add explicit domains instead of using a wildcard, you can create entries for each of the cluster’s current routes:
$ oc get --all-namespaces -o jsonpath='{range .items[*]}{range .status.ingress[*]}{.host}{"\n"}{end}{end}' routes

After you start the OKD installation on Microsoft Azure Stack Hub user-provisioned infrastructure, you can monitor the cluster events until the cluster is ready.
Deploy the bootstrap machine for an OKD cluster on user-provisioned Azure Stack Hub infrastructure.
Install the oc
CLI and log in.
Complete the cluster installation:
