Sometimes, as an admin, you may want to remove the Pentaho Data Catalog when it is no longer required, such as when decommissioning an environment, redeploying PDC with a different configuration, or freeing cluster resources. This topic describes how to uninstall Data Catalog from an OpenShift Container Platform (OCP) or OKD cluster and remove the associated OpenShift resources.
Before you begin
Ensure that the following requirements are met:
You can access the OpenShift cluster from your system.
You have permissions to delete namespaces and cluster-level resources.
You know the namespace in which Data Catalog is deployed.
Procedure
Run Helmfile to remove the Data Catalog deployment from the OpenShift cluster.
helmfile destroy -n <namespace>This command removes all Data Catalog Helm releases deployed in the specified namespace.
Delete the namespace used for the Data Catalog deployment.
kubectl delete ns <namespace>Deleting the namespace removes all remaining Kubernetes resources associated with Data Catalog.
Remove the cluster-level roles and bindings created for the Data Catalog deployment.
oc delete clusterrole secret-reader
oc delete clusterrolebinding deployer-secret-bindingThese resources are not removed automatically when the namespace is deleted.
Result
Data Catalog is removed from the OpenShift (OCP/OKD) cluster, and all associated namespaces and cluster-level resources are deleted.
