I have two servers. I manage serverA
with Ansible. serverB
is not managed with Ansible. I want serverA
to be able to access serverB
by copying the ssh_pub_key
of serverA
to serverB
.
This can be done manually by calling ssh-copy-id user@serverB
on serverA
.
I want to do this with Ansible on serverA
automatically.
- name: Register ssh key at serverB
command: ssh-copy-id -i /home/{{user}}/.ssh/id_rsa.pub -o StrictHostKeyChecking=no user@serverB
Calling ssh-copy-id
requires me to enter my ssh password for user@serverB, so the key can be copied.
How can I do this via ansible? I want it to ask for the user@serverB password interactively while executing the playbook. Storing the password in ansible vault is also an option. Then I still do not know how to avoid the interactive password call of ssh-copy-id
though.
I also added -o StrictHostKeyChecking=no
to the call because this is another interaction that normally requires user interaction when calling ssh-copy-id.

You can try
sshpass
tool. It would require modification of your command like this:but there are other options how to provide the password -- see the
sshpass(1)
manual page.
