RE: Share ssh-key with other nodes during installation



Hi Fran,

I'm not sure how to interpret your answer.
First of all I can give this information:

I ssh from my PC to my instances with ssh centos ec2 (without .pem). (To all my instances)
On my master I perform: ssh-keygen and press enter. (I tried this as root and as centos-user).

After that I perform the loop. and the permission is denied. I ran the loop as root (and also once as centos-user).

Hi Lorenz,

Is the user you are trying to copy the ssh keys capable to connect with these machines via ssh? It seems like these machines only allow connection via ssh key.

Regards.

I do not use a .pem-key to ssh to my instances. I'm performing this on a centos-instance of amazon ec2.

I've installed OpenShift origin 1.1 a few times. But I always have to copy the key manually from the master to it nodes.
But when I have to create a cluster with many nodes I want to automate this.
I saw:

# for host in master.example.com \
    node1.example.com \
    node2.example.com; \
    do ssh-copy-id -i ~/.ssh/id_rsa.pub $host; \
    done

Which looked very promissing but I always got:
/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

What's wrong with the permissions?
