We try to deploy the pod from following Kubernetes tutorial https://kubernetes.io/docs/tasks/run-application/run-stateless-application-d.... The Pod returns following error: Events: Type Reason Age From Message ---- ------ ---- ---- ------- Normal Scheduled 7d9h default-scheduler Successfully assigned default/nginx-deployment-6b474476c4-shtph to controller-0 Normal Pulling 7d9h (x3 over 7d9h) kubelet Pulling image "nginx:1.14.2" Warning Failed 7d9h (x3 over 7d9h) kubelet Failed to pull image "nginx:1.14.2": rpc error: code = Unknown desc = failed to pull and unpack image "docker.io/library/nginx:1.14.2": failed to resolve reference "docker.io/library/nginx:1.14.2": failed to do request: Head https://registry-1.docker.io/v2/library/nginx/manifests/1.14.2: x509: certificate has expired or is not yet valid Warning Failed 7d9h (x3 over 7d9h) kubelet Error: ErrImagePull Normal BackOff 7d9h (x3 over 7d9h) kubelet Back-off pulling image "nginx:1.14.2" Warning Failed 7d9h (x3 over 7d9h) kubelet Error: ImagePullBackOff We have a certification error.
