Version of certmanager CRD
I already have installed Certmanager CRDs by this doc:
and this command :
# Kubernetes 1.15+ $ kubectl apply --validate=false -f https://github.com/jetstack/cert-manager/releases/download/v0.15.1/cert-manager.crds.yaml
Because of that, when I was installing Gitlab via its helm charts I set createCustomResource to false:
certmanager: createCustomResource: false
but after installation pod
cainjector kept going on crashloopbackoff with this error:
no matches for kind "Certificate" in version "certmanager.k8s.io/v1alpha1"
I think the problem is the version of CRDs on my cluster are not the same version that Gitlab needs, but I couldn't find which version of certmanager CRDs will satisfy Gitlab.
