Redis – how to uninstall component using helm in kuberetes

I am install promethus-operator using helm v3.2.1 like this:

./helm install stable/prometheus-operator --generate-name -n dabai-pro

now I want to move the component prometheus-operator from dabai-pro namespace to monitoring namespace and want to delete this installing, I read the docs and doing like this:

[miao@MeowK8SMaster1 linux-amd64]$ ./helm uninstall stable/prometheus-operator -n dabai-pro
Error: uninstall: Release name is invalid: stable/prometheus-operator

and like this :

[miaoyou@MeowK8SMaster1 linux-amd64]$ ./helm uninstall prometheus-operator -n dabai-pro
Error: uninstall: Release not loaded: prometheus-operator: release: not found

so what should I do to remove it?

[miao@MeowK8SMaster1 linux-amd64]$ ./helm list -n dabai-pro

    Use below command to view the release name and namespacename

    helm list

    And uninstall the release by 

    helm uninstall releasename -n namespacename

    In your case it will be

    ./helm uninstall prometheus-1591246262 -n dabai-pro

    What happens when you run?

    helm list --all-namespaces

    It should list your helm deployment. The –generate-name parameter generated a random name. When you run the uninstall command, both the namespace and the generated name need to be supplied as specified in the earlier answer.

    ./helm uninstall prometheus-1591246262 -n dabai-pro
