Creating DNS records on a public DNS zone on Infoblox

You can create DNS records on a public DNS zone on Infoblox by using the Red Hat External DNS Operator.

Prerequisites

  • You have access to the OpenShift CLI (oc).

  • You have access to the Infoblox UI.

Procedure

  1. Create a secret object with Infoblox credentials by running the following command:

    $ oc -n external-dns-operator create secret generic infoblox-credentials --from-literal=EXTERNAL_DNS_INFOBLOX_WAPI_USERNAME=<infoblox_username> --from-literal=EXTERNAL_DNS_INFOBLOX_WAPI_PASSWORD=<infoblox_password>

  2. Get the routes objects to check your cluster domain by running the following command:

    $ oc get routes --all-namespaces | grep console
    Example Output
    openshift-console          console             console-openshift-console.apps.test.example.com                       console             https   reencrypt/Redirect     None
openshift-console          downloads           downloads-openshift-console.apps.test.example.com                     downloads           http    edge/Redirect          None

  3. Create an ExternalDNS resource YAML file, for example, sample-infoblox.yaml, as follows:

    apiVersion: externaldns.olm.openshift.io/v1beta1
kind: ExternalDNS
metadata:
  name: sample-infoblox
spec:
  provider:
    type: Infoblox
    infoblox:
      credentials:
        name: infoblox-credentials
      gridHost: ${INFOBLOX_GRID_PUBLIC_IP}
      wapiPort: 443
      wapiVersion: "2.3.1"
  domains:
  - filterType: Include
    matchType: Exact
    name: test.example.com
  source:
    type: OpenShiftRoute
    openshiftRouteOptions:
      routerName: default

  4. Create an ExternalDNS resource on Infoblox by running the following command:

    $ oc create -f sample-infoblox.yaml

  5. From the Infoblox UI, check the DNS records created for console routes:

    1. Click Data Management → DNS → Zones.

    2. Select the zone name.
