The 0.8 release has decoupled the addon from KubeBlocks, requiring many addons to be installed using helm install. However, an issue arises during the helm install process if the --namespace kb-system flag is not specified. Currently, there are two methods to address this:

  1. Execute kbcli kb uninstall --auto-approveagain.
  2. Install the XX-addon using helm install with the --namespace kb-system flag.

Such as:

➜  ~ helm install opengauss ./opengauss --namespace kb-system
NAME: opengauss
LAST DEPLOYED: Thu Dec 21 09:43:15 2023
NAMESPACE: kb-system
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
Standalone OpenGauss cluster-definition and cluster-version in Kubeblocks

Using `kbcli cluster create --cluster-definition opengauss` to create a OpenGauss cluster
