I was getting the same error and also needed to remove and add again the k8s integration. Does anyone know how I can tell gitlab that tiller is installed?
You don’t need to do that. When you add an already existing Kubernetes cluster to a gitlab project it doesn’t update the information about which applications are installed. But once you deploy it will discover tiller automatically.
Umm ok, doesn’t work for me but I am using a custom gitlab-ci.yml file as this is a dotnet project and auto-devops doesn’t really support that to well.
