This PR adds logs for the following containers to the logs command:

  • k8s_kube-apiserver
  • k8s_coredns_coredn
  • k8s_kube-scheduler

This PR also detects common problems within these pods, as well as the kubelet, and displays these errors if "minikube start" fails. Example output below:

💡  Tip: To create a new cluster, use 'minikube start -p <new name>' or use 'minikube delete' to delete this one.
🔄  Restarting existing none VM for "minikube" ...
⌛  Waiting for SSH access ...

💣  Error restarting cluster: restarting kube-proxy: waiting for kube-proxy to be up for configmap update: timed out waiting for the condition

😿  Sorry that minikube crashed. If this was unexpected, we would love to hear from you:

This PR resolves #3550 and #3532
