Could not sshing into dcos node using dcos node ssh --master-proxy --leader

Question

I am new in dcos Mesos, installed dc os in local Ubuntu machine.

I can view the dcos dashboard.

but I can not sshing the master node using dcos node ssh --master-proxy --leader. It says:

There is no SSH_AUTH_SOCK env variable, which likely means you aren't running ssh-agent. dcos node ssh --master-proxy/--proxy-ip depends on ssh-agent to safely use your private key to hop between nodes in your cluster. Please run ssh-agent, then add your private key with ssh-add.

as documentation, there should be .pem file in ./ssh directory. But in my Ubuntu machine I did not find .pem file of that location.

Answer 1

You should add your key to your ssh agent: This is usually done by ssh-add keyname, which requires your ssh-agent to run.

If you don't file a pem file, this usually means you haven't generated a key before. Use ssh-keygen to do so.

BTW, you are referencing an old version of the documentation, I assume you are probably running a 1.9 or 1.10 cluster, so I would make sure to use the respective documentation.
