I'm trying to make a run from my ansible master to a host (lets call it hostclient) which requires performing something into another host (let's call it susemanagerhost :) ).
hostclient needs ansible_ssh_common_args with proxycommand fullfilled, while susemanager host needs no ansible_ssh_common_args since its a direct connection.
So I thought I could use delegate_to, but the host called hostclient and the host called susemanagerhost have different values for the variable ansible_ssh_common_args.
I thought I could change the value of ansible_ssh_common_args inside the run with set_fact of ansible_ssh_common_args to ansible_ssh_common_args_backup (because I want to recover the original value for the other standard tasks) and then ansible_ssh_common_args to null (the connection from the ansible master to susemanager host is a direct connection with no proxycommand required) but it is not working.
It seems like its still using the original value for ansible_ssh_common_args.
ansible_ssh_common_args is generally used to execute commands 'through' a proxy server:
<ansible system> => <proxy system> => <intended host>
The way you formulated your question you won't need to use ansible_ssh_common_args and can stick to using delegate_to:
- name: execute on host client
shell: ls -la
- name: execute on susemanagerhost
shell: ls -la
delegate_to: "root@susemanagerhost"
Call this play with:
ansible-playbook <play> --limit=hostclient
This should do it.
Edit: After filing a bug on github the working solution is to have:
ansible_ssh_common_args: '-o StrictHostKeyChecking=no -o ProxyCommand="ssh -W %h:%p -i ~/.ssh/id_rsa ansible@{{ jumphost_server }}"'
In host_vars or group_vars.
Followed by a static use of delegate_to:
delegate_to: <hostname>
hostname should be the hostname as used by ansible.
But not use:
delegate_to: "username@hostname"
This resolved the issue for me, hope it works out for you as well.
