[Starlingx-discuss] Latest Elastic Cloud on Kubernetes can't be deployed on STX 4.0

[bnovickovs at weecodelab.com]

I am trying to deploy ECK on STX 4.0 following 
https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-quickstart.html 
;

In elastic operator logs:

{"log.level":"error","@timestamp":"2020-11-12T18:41:23.159Z","log.logger":"manager","message":"Timeout 
elapsed waiting for webhook certificate to be 
available","service.version":"1.3.0+6db1914b","service.type":"eck","ecs.version":"1.4.0","path":"/tmp/k8s-webhook-server/serving-certs/tls.crt","timeout_seconds":30,"error":"timed 
out waiting for the 
condition","error.stack_trace":"github.com/elastic/cloud-on-k8s/cmd/manager.setupWebhook\n\t/go/src/github.com/elastic/cloud-on-k8s/cmd/manager/main.go:770\ngithub.com/elastic/cloud-on-k8s/cmd/manager.startOperator\n\t/go/src/github.com/elastic/cloud-on-k8s/cmd/manager/main.go:549\ngithub.com/elastic/cloud-on-k8s/cmd/manager.doRun.func2\n\t/go/src/github.com/elastic/cloud-on-k8s/cmd/manager/main.go:316"}

{"log.level":"info","@timestamp":"2020-11-12T18:40:53.159Z","log.logger":"controller-runtime.builder","message":"skip 
registering a mutating webhook, admission.Defaulter interface is not 
implemented","service.version":"1.3.0+6db1914b","service.type":"eck","ecs.version":"1.4.0","GVK":"kibana.k8s.elastic.co/v1beta1, 
Kind=Kibana"}

and this could be related to 
https://kubernetes.io/blog/2019/03/21/a-guide-to-kubernetes-admission-controllers/ 
(--enable-admission-plugins=ValidatingAdmissionWebhook,MutatingAdmissionWebhook)

P.S. Version ECK 1.1 worked for me on STX 3.0 though.

Is there any way to overcome this issue?
