5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
Having deployed a new Kubernetes cluster with Karbon and downloaded the kubeconfig, kubectl operations result in an error:Unable to connect to the server: x509: certificate is valid for cluster.local, kubernetes, kubernetes.default, kubernetes.default.svc, kubernetes.default.svc.cluster, kubernetes.default.svc.cluster.local, cluster.local, not xxxxx What is the recommended way to add a SAN to the Karbon Kubernetes API certificate?
Hi there,It seems that I have a failure near the very end of deployment.

Hi there,We are currently deploying (and testing) Karbon as K8 orchestration platform for all our Nutanix platforms (worldwide). I have failed installation attempts from Prism Central.As a side note, we are using VPN Site2Site from centralised Prism Control and I can reach remote K8 VLAN from distant Nutanix deployment. The reachout tests were done with small VM belonging the the K8 VLAN testing node and via private CIDR (bidirectional tests), but utilizing the same encrypted VPN channel.This is what I’m having from karbon_core.out (PCVM):2021-10-13T21:17:12.687Z ssh.go:153: [DEBUG] [k8s_cluster=RGS-PA-K8-STAGING] On 10.20.25.130:22 executing: docker plugin inspect nutanix2021-10-13T21:17:12.825Z ssh.go:166: [WARN] [k8s_cluster=RGS-PA-K8-STAGING] Run cmd failed: Failed to run command: on host(10.20.25.130:22) cmd(docker plugin inspect nutanix) error: "Process exited with status 1", output: "Error: No such plugin: nutanix\n[]\n"2021-10-13T21:17:12.825Z sshutils.go:44: [ERROR] [k8s_clust
