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:

    1. $ 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:

    1. $ oc get routes --all-namespaces | grep console

    Example Output

    1. openshift-console          console             console-openshift-console.apps.test.example.com                       console             https   reencrypt/Redirect     None
    2. 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:

    1. apiVersion: externaldns.olm.openshift.io/v1beta1
    2. kind: ExternalDNS
    3. metadata:
    4.   name: sample-infoblox
    5. spec:
    6.   provider:
    7.     type: Infoblox
    8.     infoblox:
    9.       credentials:
    10.         name: infoblox-credentials
    11.       gridHost: ${INFOBLOX_GRID_PUBLIC_IP}
    12.       wapiPort: 443
    13.       wapiVersion: "2.3.1"
    14.   domains:
    15.   - filterType: Include
    16.     matchType: Exact
    17.     name: test.example.com
    18.   source:
    19.     type: OpenShiftRoute
    20.     openshiftRouteOptions:
    21.       routerName: default

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

    1. $ 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.
