问题
I'm trying to configure HTTPS for my K8s/Istio cluster. I'm following this official tutorial step by step multiple times from scratch and get the same error every time when try to create a Certificate resource.
no matches for kind "Certificate" in version "certmanager.k8s.io/v1alpha1"
I tried to install cert-manager and its CRD manually based on official docs and no help.
cert-manager-5ff755b6d5-9ncgr 1/1 Running 0 6m55s
cert-manager-cainjector-576978ffc8-4db4l 1/1 Running 0 6m55s
cert-manager-webhook-c67fbc858-wvtgs 1/1 Running 0 6m55s
Can't find any piece of information regarding this error since it works foe everyone after installing out of the box or after installing cert-manager's CRD.

I suggest you to try this installation for cert-manager and thereafter you can follow this stackoverflow post , it will get the issue sorted, I guess. You just need to make few substitutions at places where ingress has to be replaced with istio.
Kindly use
apiVersion: cert-manager.io/v1alpha2
in clusterissuer, if the apiVersion for clusterIssuer present in that stackoverflow post is not acceptable
