Hello,
I know I have seen some discussion on this topic both in this group and on the Kubernetes github issues, but I haven't found a good solution, so I thought I would add my experience to the mix. Earlier this week, Oraclelinux added Kubernetes support through its yum repositories. In an effort to try the new goodies, I installed the latest public repositories and proceeded to follow the installation guide at: https://docs.oracle.com/cd/E52668_01/E88884/html/index.html After installing all the prerequisites, on a fresh installation of oraclelinux 7.3, as root I ran: # kubeadm init All goes well until: [apiclient] Created API client, waiting for the control plane to become ready At this point the initialization hangs and never completes. I waited over an hour to see if it would finish but no luck. The complete log of my kubeadm init follows: ---- log ---- [init] Using Kubernetes version: v1.7.6 [init] Using Authorization modes: [Node RBAC] [preflight] Running pre-flight checks [preflight] Starting the kubelet service [kubeadm] WARNING: starting in 1.8, tokens expire after 24 hours by default (if you require a non-expiring token use --token-ttl 0) [certificates] Generated CA certificate and key.

Any suggestions would be welcome. TIA, Don -- You received this message because you are subscribed to the Google Groups "Kubernetes user discussion and Q&A" group.
