How to Replace clusterDomain From the Default Value local?

Problem

By default all Kubernetes clusters are configured with clusterDomain value set to "local" in the config. At times there are requirements to have custom values for clusterDomain per cluster.

kubectl  config view -n kube-system

apiVersion: v1

clusters:

- cluster:

    certificate-authority-data: DATA+OMITTED

    server: https://<IP>:443

  name: local

contexts:

- context:

    cluster: local

    namespace: default

    user: admin

  name: default-context

- context:

    cluster: local

    namespace: kube-system

    user: admin

  name: system-context

current-context: default-context

kind: Config

preferences: {}

users:

- name: admin

  user:

    client-certificate-data: REDACTED

    client-key-data: REDACTED

Environment

• Platform9 Edge Cloud- v5.3 and higher.
• Platform9 Managed Kubernetes - v5.6 and higher.

Answer

The supportability for the custom cluserDomain will be available in the SMCP-v5.12 and PMK-v5.12 releases.

Additional Information

Platform9 team has filed a Jira PMK-5881 to track this issue. The ETA for the release is not available at the moment.
