How to list installed Kubernetes operators, and delete them, via kubectl?

How can I use kubectl to list all the installed operators in my cluster? For instance running:

kubectl apply -f https://raw.githubusercontent.com/reactive-tech/kubegres/v1.9/kubegres.yaml

installs the Kubegres (Postgres cluster provider) operator, but then how do I actually see that in a list of operators. Equally important to that, how do I uninstall the operator from my cluster via kubectl, or is that not possible to do?

Solution

  • Unless you are using OLM to manage operator, there is no universal way to get rid of it.

    Some operator might be installed using Helm, then it's just matter of helm delete ...

    You can always try to remove it using

    kubectl delete -f https://raw.githubusercontent.com/reactive-tech/kubegres/v1.9/kubegres.yaml

    Generally speaking, to remove something, use same tool that you used for installation.
