Hi Team, I have deployed K8s cluster using Magnum Openstack Rocky Release. I have one master node and one slave node in my cluster. But when I try to create a POD on master node using the command *kubectl run nginx --image=nginx* My Container remains in ContainerCreating State. When I debugged into the issue, I found the below error *Warning FailedCreatePodSandBox 59s (x24 over 32m) kubelet, kubernetes-cluster-w6csm5uqyspz-minion-0 Failed create pod sandbox: rpc error: code = Unknown desc = failed pulling image "gcr.io/google_containers/pause:3.0 <http://gcr.io/google_containers/pause:3.0>": x509: certificate signed by unknown authority* However, in */etc/sysconfig/docker* file, I have disabled the gcr.io repository. OPTIONS='--insecure-registry="gcr.io,googleapis.com" --selinux-enabled ' The docker is successfully pulling the *gcr.io/google_containers/pause:3.0 <http://gcr.io/google_containers/pause:3.0> image,* BUT kubernetes is neither able to use local repository nor able to pull the image. Can someone please help me in resolving the *x509: certificate signed by unknown authority issue?* Regards Anirudh Gupta
