I’m attempting to automate my setup of my raspberry pi cluster by using ansible. The playbook I have so far is:
- hosts: pis become: yes gather_facts: no pre_tasks: - name: 'install ssh key ros config' raw: "sudo ros config set ssh_authorized_keys \"['[my-public-key]']\"" - name: 'install ssh key copy' raw: "sudo mkdir -p /home/rancher/.ssh && rm -f /home/rancher/.ssh/authorized_keys && echo \"ssh-rsa [my-public-key]\" >> /home/rancher/.ssh/authorized_keys && chmod -R 0600 /home/rancher/.ssh && chmod u+x /home/rancher/.ssh && chown -R rancher:rancher /home/rancher/.ssh" # unsure if this works or just bricks them. Seems to lose the ability to remote into them? # - name: 'set new console' # raw: 'sudo ros console switch -f ubuntu'
As you might guess, the commented area is what’s giving me problems: if I enable a switch to ubuntu, the pis become unusable - if I try to remote into them with the same ssh command I would’ve if I didn’t issue the ros console switch, I can’t log in. In fact it looks like the ssh daemon isn’t running at all:
# ssh -vvv -i ~/.ssh/id_rsa firstname.lastname@example.org OpenSSH_7.6p1 Ubuntu-4ubuntu0.3, OpenSSL 1.0.2n 7 Dec 2017 debug1: Reading configuration data /root/.ssh/config debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug2: resolving "10.0.0.20" port 22 debug2: ssh_connect_direct: needpriv 0 debug1: Connecting to 10.0.0.20 [10.0.0.20] port 22. debug1: connect to address 10.0.0.20 port 22: Connection refused ssh: connect to host 10.0.0.20 port 22: Connection refused
Again, to be clear - if I don’t do the switch console everything is fine.
Is there something I’m missing that I should do to allow switching consoles?
