Custom catalogs using the Bundle Format

Prerequisites

Install the opm CLI.

Creating an index image

You can create an index image using the opm CLI.

Prerequisites

opm version 1.12.3+
podman version 1.9.3+
A bundle image built and pushed to a registry that supports Docker v2-2

The internal registry of the OKD cluster cannot be used as the target registry because it does not support pushing without a tag, which is required during the mirroring process.

Procedure

Start a new index:

$ opm index add \
    --bundles <registry>/<namespace>/<bundle_image_name>:<tag> \(1)
    --tag <registry>/<namespace>/<index_image_name>:<tag> \(2)
    [--binary-image <registry_base_image>] (3)

1	Comma-separated list of bundle images to add to the index.
2	The image tag that you want the index image to have.
3	Optional: An alternative registry base image to use for serving the catalog.

Push the index image to a registry.
1. If required, authenticate with your target registry:
  $ podman login <registry>
2. Push the index image:
  $ podman push <registry>/<namespace>/test-catalog:latest

Creating a catalog from an index image

You can create an Operator catalog from an index image and apply it to an OKD cluster for use with Operator Lifecycle Manager (OLM).

Prerequisites

An index image built and pushed to a registry.

Procedure

Create a CatalogSource object that references your index image.

Modify the following to your specifications and save it as a catalogSource.yaml file:

apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: my-operator-catalog
  namespace: olm (1)
spec:
  sourceType: grpc
  image: <registry>:<port>/<namespace>/catalog:latest (2)
  displayName: My Operator Catalog
  publisher: <publisher_name> (3)
  updateStrategy:
    registryPoll: (4)
      interval: 30m

1	If you want the catalog source to be available globally to users in all namespaces, specify the `olm` namespace. Otherwise, you can specify a different namespace for the catalog to be scoped and available only for that namespace.
2	Specify your index image.
3	Specify your name or an organization name publishing the catalog.
4	Catalog sources can automatically check for new versions to keep up to date.

Use the file to create the CatalogSource object:
```
$ oc apply -f catalogSource.yaml
```

Verify the following resources are created successfully.

Check the pods:

$ oc get pods -n olm

Example output

NAME                                    READY   STATUS    RESTARTS  AGE
my-operator-catalog-6njx6               1/1     Running   0         28s
marketplace-operator-d9f549946-96sgr    1/1     Running   0         26h

Check the catalog source:

$ oc get catalogsource -n olm

Example output

NAME                  DISPLAY               TYPE PUBLISHER  AGE
my-operator-catalog   My Operator Catalog   grpc            5s

Check the package manifest:

$ oc get packagemanifest -n olm

Example output

NAME                          CATALOG               AGE
jaeger-product                My Operator Catalog   93s

You can now install the Operators from the OperatorHub page on your OKD web console.

Updating an index image

After configuring OperatorHub to use a catalog source that references a custom index image, cluster administrators can keep the available Operators on their cluster up to date by adding bundle images to the index image.

You can update an existing index image using the opm index add command.

Prerequisites

opm version 1.12.3+
podman version 1.9.3+
An index image built and pushed to a registry.
An existing catalog source referencing the index image.

Procedure

Update the existing index by adding bundle images:

$ opm index add \
    --bundles <registry>/<namespace>/<new_bundle_image>@sha256:<digest> \(1)
    --from-index <registry>/<namespace>/<existing_index_image>:<existing_tag> \(2)
    --tag <registry>/<namespace>/<existing_index_image>:<updated_tag> \(3)
    --pull-tool podman (4)

1	The `--bundles` flag specifies a comma-separated list of additional bundle images to add to the index.
2	The `--from-index` flag specifies the previously pushed index.
3	The `--tag` flag specifies the image tag to apply to the updated index image.
4	The `--pull-tool` flag specifies the tool used to pull container images.

where:

<registry>: Specifies the hostname of the registry, such as quay.io or mirror.example.com.
<namespace>: Specifies the namespace of the registry, such as ocs-dev or abc.
<new_bundle_image>: Specifies the new bundle image to add to the registry, such as ocs-operator.
<digest>: Specifies the SHA image ID, or digest, of the bundle image, such as c7f11097a628f092d8bad148406aa0e0951094a03445fd4bc0775431ef683a41.
<existing_index_image>: Specifies the previously pushed image, such as abc-redhat-operator-index.
<existing_tag>: Specifies a previously pushed image tag, such as 4.6.
<updated_tag>: Specifies the image tag to apply to the updated index image, such as 4.6.1.

Example command

$ opm index add \
    --bundles quay.io/ocs-dev/ocs-operator@sha256:c7f11097a628f092d8bad148406aa0e0951094a03445fd4bc0775431ef683a41 \
    --from-index mirror.example.com/abc/abc-redhat-operator-index:4.6 \
    --tag mirror.example.com/abc/abc-redhat-operator-index:4.6.1 \
    --pull-tool podman

Push the updated index image:

$ podman push <registry>/<namespace>/<existing_index_image>:<updated_tag>

After Operator Lifecycle Manager (OLM) automatically polls the index image referenced in the catalog source at its regular interval, verify that the new packages are successfully added:
```
$ oc get packagemanifests -n openshift-marketplace
```

Pruning an index image

An index image, based on the Operator Bundle Format, is a containerized snapshot of an Operator catalog. You can prune an index of all but a specified list of packages, which creates a copy of the source index containing only the Operators that you want.

Prerequisites

podman version 1.9.3+
grpcurl (third-party command-line tool)
opm version 1.18.0+
Access to a registry that supports Docker v2-2

The internal registry of the OKD cluster cannot be used as the target registry because it does not support pushing without a tag, which is required during the mirroring process.

Procedure

Authenticate with your target registry:
```
$ podman login <target_registry>
```
Determine the list of packages you want to include in your pruned index.
1. Run the source index image that you want to prune in a container. For example:
  $ podman run -p50051:50051 \ -it quay.io/operatorhubio/catalog:latest
  Example output
  Trying to pull quay.io/operatorhubio/catalog:latest... Getting image source signatures Copying blob ae8a0c23f5b1 done ... INFO[0000] serving registry database=/database/index.db port=50051
2. In a separate terminal session, use the grpcurl command to get a list of the packages provided by the index:
  $ grpcurl -plaintext localhost:50051 api.Registry/ListPackages > packages.out
3. Inspect the packages.out file and identify which package names from this list you want to keep in your pruned index. For example:
  Example snippets of packages list
  ... { "name": "couchdb-operator" } ... { "name": "eclipse-che" } ... { { "name": "etcd" } ...
4. In the terminal session where you executed the podman run command, press Ctrl and C to stop the container process.

Run the following command to prune the source index of all but the specified packages:

$ opm index prune \
    -f quay.io/operatorhubio/catalog:latest \(1)
    -p couchdb-operator,eclipse-che,etcd \(2)
    [-i quay.io/openshift/origin-operator-registry:4.6.0] \(3)
    -t <target_registry>:<port>/<namespace>/catalog:latest (4)

1	Index to prune.
2	Comma-separated list of packages to keep.
3	Required only for IBM Power Systems and IBM Z images: Operator Registry base image with the tag that matches the target OKD cluster major and minor version.
4	Custom tag for new index image being built.

Run the following command to push the new index image to your target registry:
```
$ podman push <target_registry>:<port>/<namespace>/catalog:latest
```
where <namespace> is any existing namespace on the registry.

Custom catalogs using the Package Manifest Format

Building a Package Manifest Format catalog image

Cluster administrators can build a custom Operator catalog image based on the Package Manifest Format to be used by Operator Lifecycle Manager (OLM). The catalog image can be pushed to a container image registry that supports Docker v2-2. For a cluster on a restricted network, this registry can be a registry that the cluster has network access to, such as a mirror registry created during a restricted network cluster installation.

The internal registry of the OKD cluster cannot be used as the target registry because it does not support pushing without a tag, which is required during the mirroring process.

For this example, the procedure assumes use of a mirror registry that has access to both your network and the Internet.

Only the Linux version of the oc client can be used for this procedure, because the Windows and macOS versions do not provide the oc adm catalog build command.

Prerequisites

Workstation with unrestricted network access
oc version 4.3.5+ Linux client
podman version 1.9.3+
Access to mirror registry that supports Docker v2-2
If you are working with private registries, set the REG_CREDS environment variable to the file path of your registry credentials for use in later steps. For example, for the podman CLI:
```
$ REG_CREDS=${XDG_RUNTIME_DIR}/containers/auth.json
```

If you are working with private namespaces that your quay.io account has access to, you must set a Quay authentication token. Set the AUTH_TOKEN environment variable for use with the --auth-token flag by making a request against the login API using your quay.io credentials:

$ AUTH_TOKEN=$(curl -sH "Content-Type: application/json" \
    -XPOST https://quay.io/cnr/api/v1/users/login -d '
    {
        "user": {
            "username": "'"<quay_username>"'",
            "password": "'"<quay_password>"'"
        }
    }' | jq -r '.token')

Procedure

On the workstation with unrestricted network access, authenticate with the target mirror registry:
```
$ podman login <registry_host_name>
```

Build a catalog image based on the redhat-operators catalog from Quay.io, tagging and pushing it to your mirror registry:

$ oc adm catalog build \
    --appregistry-org redhat-operators \(1)
    --from=quay.io/openshift/origin-operator-registry:4.6.0 \(2)
    --filter-by-os="linux/amd64" \(3)
    --to=<registry_host_name>:<port>/olm/redhat-operators:v1 \(4)
    [-a ${REG_CREDS}] \(5)
    [--insecure] \(6)
    [--auth-token "${AUTH_TOKEN}"] (7)

1	Organization (namespace) to pull from an App Registry instance.
2	Set `--from` to the Operator Registry base image using the tag that matches the target OKD cluster major and minor version.
3	Set `--filter-by-os` to the operating system and architecture to use for the base image, which must match the target OKD cluster. Valid values are `linux/amd64`, `linux/ppc64le`, and `linux/s390x`.
4	Name your catalog image and include a tag, for example, `v1`.
5	Optional: If required, specify the location of your registry credentials file.
6	Optional: If you do not want to configure trust for the target registry, add the `--insecure` flag.
7	Optional: If other application registry catalogs are used that are not public, specify a Quay authentication token.

Example output

INFO[0013] loading Bundles                               dir=/var/folders/st/9cskxqs53ll3wdn434vw4cd80000gn/T/300666084/manifests-829192605

Sometimes invalid manifests are accidentally introduced catalogs provided by Red Hat; when this happens, you might see some errors:

Example output with errors

...
INFO[0014] directory                                     dir=/var/folders/st/9cskxqs53ll3wdn434vw4cd80000gn/T/300666084/manifests-829192605 file=4.2 load=package

Uploading ... 244.9kB/s

These errors are usually non-fatal, and if the Operator package mentioned does not contain an Operator you plan to install or a dependency of one, then they can be ignored.

Mirroring images for a disconnected installation

Mirroring a Package Manifest Format catalog image

Cluster administrators can mirror a custom Operator catalog image based on the Package Manifest Format into a registry and use a catalog source to load the content onto their cluster. For this example, the procedure uses a custom redhat-operators catalog image previously built and pushed to a supported registry.

Prerequisites

Workstation with unrestricted network access
A custom Operator catalog image based on the Package Manifest Format pushed to a supported registry
oc version 4.3.5+
podman version 1.9.3+
Access to mirror registry that supports Docker v2-2

The internal registry of the OKD cluster cannot be used as the target registry because it does not support pushing without a tag, which is required during the mirroring process.
If you are working with private registries, set the REG_CREDS environment variable to the file path of your registry credentials for use in later steps. For example, for the podman CLI:
```
$ REG_CREDS=${XDG_RUNTIME_DIR}/containers/auth.json
```

Procedure

The oc adm catalog mirror command extracts the contents of your custom Operator catalog image to generate the manifests required for mirroring. You can choose to either:

Allow the default behavior of the command to automatically mirror all of the image content to your mirror registry after generating manifests, or
Add the --manifests-only flag to only generate the manifests required for mirroring, but do not actually mirror the image content to a registry yet. This can be useful for reviewing what will be mirrored, and it allows you to make any changes to the mapping list if you only require a subset of the content. You can then use that file with the oc image mirror command to mirror the modified list of images in a later step.

On your workstation with unrestricted network access, run the following command:

$ oc adm catalog mirror \
    <registry_host_name>:<port>/olm/redhat-operators:v1 \ (1)
    <registry_host_name>:<port> \ (2)
    [-a ${REG_CREDS}] \ (3)
    [--insecure] \ (4)
    [--index-filter-by-os='<platform>/<arch>'] \ (5)
    [--manifests-only] (6)

1	Specify your Operator catalog image.
2	Specify the fully qualified domain name (FQDN) for the target registry.
3	Optional: If required, specify the location of your registry credentials file.
4	Optional: If you do not want to configure trust for the target registry, add the `--insecure` flag.
5	Optional: Specify which platform and architecture of the catalog image to select when multiple variants are available. Images are passed as `'<platform>/<arch>[/<variant>]'`. This does not apply to images referenced by the catalog image. Valid values are `linux/amd64`, `linux/ppc64le`, and `linux/s390x`.
6	Optional: Only generate the manifests required for mirroring and do not actually mirror the image content to a registry.

Example output

using database path mapping: /:/tmp/190214037
wrote database to /tmp/190214037
using database at: /tmp/190214037/bundles.db (1)
...

1	Temporary database generated by the command.

After running the command, a manifests-<index_image_name>-<random_number>/ directory is created in the current directory and generates the following files:

The catalogSource.yaml file is a basic definition for a CatalogSource object that is pre-populated with your catalog image tag and other relevant metadata. This file can be used as is or modified to add the catalog source to your cluster.

The imageContentSourcePolicy.yaml file defines an ImageContentSourcePolicy object that can configure nodes to translate between the image references stored in Operator manifests and the mirrored registry.

If your cluster uses an ImageContentSourcePolicy object to configure repository mirroring, you can use only global pull secrets for mirrored registries. You cannot add a pull secret to a project.

The mapping.txt file contains all of the source images and where to map them in the target registry. This file is compatible with the oc image mirror command and can be used to further customize the mirroring configuration.

If you used the --manifests-only flag in the previous step and want to mirror only a subset of the content:

Modify the list of images in your mapping.txt file to your specifications. If you are unsure of the exact names and versions of the subset of images you want to mirror, use the following steps to find them:
1. Run the sqlite3 tool against the temporary database that was generated by the oc adm catalog mirror command to retrieve a list of images matching a general search query. The output helps inform how you will later edit your mapping.txt file.
  
  For example, to retrieve a list of images that are similar to the string clusterlogging.4.3:
  $ echo "select * from related_image \ where operatorbundle_name like 'clusterlogging.4.3%';" \ | sqlite3 -line /tmp/190214037/bundles.db (1)
  1 Refer to the previous output of the oc adm catalog mirror command to find the path of the database file.
  Example output
  image = registry.redhat.io/openshift4/ose-logging-kibana5@sha256:aa4a8b2a00836d0e28aa6497ad90a3c116f135f382d8211e3c55f34fb36dfe61 operatorbundle_name = clusterlogging.4.3.33-202008111029.p0 image = registry.redhat.io/openshift4/ose-oauth-proxy@sha256:6b4db07f6e6c962fc96473d86c44532c93b146bbefe311d0c348117bf759c506 operatorbundle_name = clusterlogging.4.3.33-202008111029.p0 ...
2. Use the results from the previous step to edit the mapping.txt file to only include the subset of images you want to mirror.
  
  For example, you can use the image values from the previous example output to find that the following matching lines exist in your mapping.txt file:
  Matching image mappings in mapping.txt
  registry.redhat.io/openshift4/ose-logging-kibana5@sha256:aa4a8b2a00836d0e28aa6497ad90a3c116f135f382d8211e3c55f34fb36dfe61=<registry_host_name>:<port>/openshift4-ose-logging-kibana5:a767c8f0 registry.redhat.io/openshift4/ose-oauth-proxy@sha256:6b4db07f6e6c962fc96473d86c44532c93b146bbefe311d0c348117bf759c506=<registry_host_name>:<port>/openshift4-ose-oauth-proxy:3754ea2b
  In this example, if you only want to mirror these images, you would then remove all other entries in the mapping.txt file and leave only the above two lines.

Still on your workstation with unrestricted network access, use your modified mapping.txt file to mirror the images to your registry using the oc image mirror command:

$ oc image mirror \
    [-a ${REG_CREDS}] \
    --filter-by-os='.*' \
    -f ./manifests-redhat-operators-<random_number>/mapping.txt

If the --filter-by-os flag remains unset or set to any value other than .*, the command filters out different architectures, which changes the digest of the manifest list, also known as a multi-arch image. The incorrect digest causes deployments of those images and Operators on disconnected clusters to fail.

Create the ImageContentSourcePolicy object:

$ oc create -f ./manifests-redhat-operators-<random_number>/imageContentSourcePolicy.yaml

You can now create a CatalogSource object to reference your mirrored content.

Updating a Package Manifest Format catalog image

After a cluster administrator has configured OperatorHub to use custom Operator catalog images, administrators can keep their OKD cluster up to date with the latest Operators by capturing updates made to App Registry catalogs provided by Red Hat. This is done by building and pushing a new Operator catalog image, then replacing the existing spec.image parameter in the CatalogSource object with the new image digest.

For this example, the procedure assumes a custom redhat-operators catalog image is already configured for use with OperatorHub.

Only the Linux version of the oc client can be used for this procedure, because the Windows and macOS versions do not provide the oc adm catalog build command.

Prerequisites

Workstation with unrestricted network access
oc version 4.3.5+ Linux client
podman version 1.9.3+
Access to mirror registry that supports Docker v2-2

The internal registry of the OKD cluster cannot be used as the target registry because it does not support pushing without a tag, which is required during the mirroring process.
OperatorHub configured to use custom catalog images
If you are working with private registries, set the REG_CREDS environment variable to the file path of your registry credentials for use in later steps. For example, for the podman CLI:
```
$ REG_CREDS=${XDG_RUNTIME_DIR}/containers/auth.json
```

$ AUTH_TOKEN=$(curl -sH "Content-Type: application/json" \
    -XPOST https://quay.io/cnr/api/v1/users/login -d '
    {
        "user": {
            "username": "'"<quay_username>"'",
            "password": "'"<quay_password>"'"
        }
    }' | jq -r '.token')

Procedure

On the workstation with unrestricted network access, authenticate with the target mirror registry:
```
$ podman login <registry_host_name>
```
Authenticate with registry.redhat.io so that the base image can be pulled during the build:
```
$ podman login registry.redhat.io
```

Build a new catalog image based on the redhat-operators catalog from Quay.io, tagging and pushing it to your mirror registry:

$ oc adm catalog build \
    --appregistry-org redhat-operators \(1)
    --from=quay.io/openshift/origin-operator-registry:4.6.0 \(2)
    --filter-by-os="linux/amd64" \(3)
    --to=<registry_host_name>:<port>/olm/redhat-operators:v2 \(4)
    [-a ${REG_CREDS}] \(5)
    [--insecure] \(6)
    [--auth-token "${AUTH_TOKEN}"] (7)

1	Organization (namespace) to pull from an App Registry instance.
2	Set `--from` to the Operator Registry base image using the tag that matches the target OKD cluster major and minor version.
3	Set `--filter-by-os` to the operating system and architecture to use for the base image, which must match the target OKD cluster. Valid values are `linux/amd64`, `linux/ppc64le`, and `linux/s390x`.
4	Name your catalog image and include a tag, for example, `v2` because it is the updated catalog.
5	Optional: If required, specify the location of your registry credentials file.
6	Optional: If you do not want to configure trust for the target registry, add the `--insecure` flag.
7	Optional: If other application registry catalogs are used that are not public, specify a Quay authentication token.

Example output

Mirror the contents of your catalog to your target registry. The following oc adm catalog mirror command extracts the contents of your custom Operator catalog image to generate the manifests required for mirroring and mirrors the images to your registry:

$ oc adm catalog mirror \
    <registry_host_name>:<port>/olm/redhat-operators:v2 \ (1)
    <registry_host_name>:<port> \ (2)
    [-a ${REG_CREDS}] \ (3)
    [--insecure] \ (4)
    [--index-filter-by-os='<platform>/<arch>'] (5)

1	Specify your new Operator catalog image.
2	Specify the fully qualified domain name (FQDN) for the target registry.
3	Optional: If required, specify the location of your registry credentials file.
4	Optional: If you do not want to configure trust for the target registry, add the `--insecure` flag.
5	Optional: Specify which platform and architecture of the catalog image to select when multiple variants are available. Images are passed as `'<platform>/<arch>[/<variant>]'`. This does not apply to images referenced by the catalog image. Valid values are `linux/amd64`, `linux/ppc64le`, and `linux/s390x`.

Apply the newly generated manifests:
```
$ oc replace -f ./manifests-redhat-operators-<random_number>
```
It is possible that you do not need to apply the imageContentSourcePolicy.yaml manifest. Complete a diff of the files to determine if changes are necessary.
Update your CatalogSource object that references your catalog image.
1. If you have your original catalogsource.yaml file for this CatalogSource object:
  1. Edit your catalogsource.yaml file to reference your new catalog image in the spec.image field:
    
    apiVersion: operators.coreos.com/v1alpha1 kind: CatalogSource metadata: name: my-operator-catalog namespace: openshift-marketplace spec: sourceType: grpc image: <registry_host_name>:<port>/olm/redhat-operators:v2 (1) displayName: My Operator Catalog publisher: grpc
    
    1 Specify your new Operator catalog image.
  2. Use the updated file to replace the CatalogSource object:
    
    $ oc replace -f catalogsource.yaml
2. Alternatively, edit the catalog source using the following command and reference your new catalog image in the spec.image parameter:
  $ oc edit catalogsource <catalog_source_name> -n openshift-marketplace

Updated Operators should now be available from the OperatorHub page on your OKD cluster.

Testing a Package Manifest Format catalog image

You can validate Operator catalog image content by running it as a container and querying its gRPC API. To further test the image, you can then resolve a subscription in Operator Lifecycle Manager (OLM) by referencing the image in a catalog source. For this example, the procedure uses a custom redhat-operators catalog image previously built and pushed to a supported registry.

Prerequisites

A custom Package Manifest Format catalog image pushed to a supported registry
podman version 1.9.3+
oc version 4.3.5+
Access to mirror registry that supports Docker v2-2

The internal registry of the OKD cluster cannot be used as the target registry because it does not support pushing without a tag, which is required during the mirroring process.
grpcurl

Procedure

Pull the Operator catalog image:

$ podman pull <registry_host_name>:<port>/olm/redhat-operators:v1

Run the image:

$ podman run -p 50051:50051 \
    -it <registry_host_name>:<port>/olm/redhat-operators:v1

Query the running image for available packages using grpcurl:

$ grpcurl -plaintext localhost:50051 api.Registry/ListPackages

Example output

{
  "name": "3scale-operator"

Get the latest Operator bundle in a channel:

$  grpcurl -plaintext -d '{"pkgName":"kiali-ossm","channelName":"stable"}' localhost:50051 api.Registry/GetBundleForChannel

Example output

{
  "csvName": "kiali-operator.v1.0.7",
  "packageName": "kiali-ossm",
  "channelName": "stable",
...

Get the digest of the image:

$ podman inspect \
    --format='{{index .RepoDigests 0}}' \
    <registry_host_name>:<port>/olm/redhat-operators:v1

Example output

example_registry:5000/olm/redhat-operators@sha256:f73d42950021f9240389f99ddc5b0c7f1b533c054ba344654ff1edaf6bf827e3

Assuming an Operator group exists in namespace my-ns that supports your Operator and its dependencies, create a CatalogSource object using the image digest. For example:

apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: custom-redhat-operators
  namespace: my-ns
spec:
  sourceType: grpc
  image: example_registry:5000/olm/redhat-operators@sha256:f73d42950021f9240389f99ddc5b0c7f1b533c054ba344654ff1edaf6bf827e3
  displayName: Red Hat Operators

Create a subscription that resolves the latest available servicemeshoperator and its dependencies from your catalog image:

apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: servicemeshoperator
  namespace: my-ns
spec:
  source: custom-redhat-operators
  sourceNamespace: my-ns
  name: servicemeshoperator
  channel: "1.0"

Disabling the default OperatorHub sources

Operator catalogs that source content provided by Red Hat and community projects are configured for OperatorHub by default during an OKD installation. As a cluster administrator, you can disable the set of default catalogs.

Procedure

Disable the sources for the default catalogs by adding disableAllDefaultSources: true to the OperatorHub object:

$ oc patch OperatorHub cluster --type json \
    -p '[{"op": "add", "path": "/spec/disableAllDefaultSources", "value": true}]'

Alternatively, you can use the web console to manage catalog sources. From the Administration → Cluster Settings → Global Configuration → OperatorHub page, click the Sources tab, where you can create, delete, disable, and enable individual sources.

Removing custom catalogs

As a cluster administrator, you can remove custom Operator catalogs that have been previously added to your cluster by deleting the related catalog source.

Procedure

In the Administrator perspective of the web console, navigate to Administration → Cluster Settings.
Click the Global Configuration tab, and then click OperatorHub.
Click the Sources tab.
Select the Options menu for the catalog that you want to remove, and then click Delete CatalogSource.
