So I have been trying to build ssh connections between google cluster container containing 1 master node and 2 worker nodes. I have used ssh-keygen to generate key pairs for all three nodes, send the two private keys of the 2 workers to the master node and into the .ssh/autherized_keys file. Then I shared this file with the two worker nodes too.
This approach makes successful ssh connections right after. The ssh connection was fine and I could also use scp to send over files. Yet as in later stages as I logout and re-login into the VMs, the ssh connection became very unstable, as sometimes it returns connection failure error : Permission denied (publickey), while sometimes the connection could be again triggered.
Anyone knows what the problem is? Thanks in advance!
1More info is needed to properly diagnose this. What's the output of
ssh -v thehostnameyouwanttoconnectto.com
