5 Uninstalling Cloud Native Core Policy (CNC Policy)

When you uninstall a Helm chart from your Cloud Native Core Policy (CNC Policy) deployment, it removes only the Kubernetes objects that it created during installation.

To uninstall, enter this command:

helm delete release_name

where release_name is the release name used by helm command.

Helm keeps a record of its releases, so you can still re-activate the release after you uninstall it.

To completely remove the release from the cluster, add the --purge option to the command:

helm delete --purge release_name

For example, to completely remove a release named "occnp",enter this command:

helm delete --purge occnp

Deleting Kubernetes Namespace

To delete kubernetes namespace, enter this command:

kubectl delete namespace release_namespace

where release_namespace is the deployment namespace used by helm command.

For example, to delete a kubernetes namespace named "occnp", enter this command:

kubectl delete namespace occnp

Cleaning Up Database

To clean up database for the different microservices:

DROP DATABASE IF EXISTS occnp_audit_service;
DROP DATABASE IF EXISTS occnp_config_server;
DROP DATABASE IF EXISTS occnp_pcf_am;
DROP DATABASE IF EXISTS occnp_pcf_sm;
DROP DATABASE IF EXISTS occnp_pcf_user;
DROP DATABASE IF EXISTS occnp_pcrf_core;
DROP DATABASE IF EXISTS occnp_release;
DROP DATABASE IF EXISTS occnp_binding;
