|
|
|
|
[role="_abstract"]
|
|
As a cluster administrator, you can modify an existing Ingress Controller to manually manage the DNS record lifecycle.
|
|
|
|
.Prerequisites
|
|
|
|
* You have installed the {oc-first}.
|
|
* You are logged in as a user with `cluster-admin` privileges.
|
|
|
|
.Procedure
|
|
|
|
. Modify the chosen Ingress Controller to set the `dnsManagementPolicy` parameter:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ SCOPE=$(oc -n openshift-ingress-operator get ingresscontroller <name> -o=jsonpath="{.status.endpointPublishingStrategy.loadBalancer.scope}")
|
|
----
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc -n openshift-ingress-operator patch ingresscontrollers/default --type=merge --patch="{\"spec\":{\"endpointPublishingStrategy\":{\"type\":\"LoadBalancerService\",\"loadBalancer\":{\"dnsManagementPolicy\":\"Unmanaged\", \"scope\":\"${SCOPE}\"}}}}"
|
|
ingresscontroller.operator.openshift.io/default patched
|
|
----
|
|
|
|
. Verify that the Ingress Controller was modified correctly by running the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc get ingresscontroller <name> -n openshift-ingress-operator -o=jsonpath={.spec.endpointPublishingStrategy.loadBalancer}
|
|
----
|

Inspect the output and confirm that `dnsManagementPolicy` is set to `Unmanaged`.
