Ansible Using Custom ssh config File

Question

I have a custom SSH config file that I typically use as follows

ssh -F ~/.ssh/client_1_config amazon-server-01 

Is it possible to assign Ansible to use this config for certain groups? It already has the keys and ports and users all set up. I have this sort of config for multiple clients, and would like to keep the config separate if possible.

Answer 1

Not fully possible. You can set ssh arguments in the ansible.cfg:

[ssh_connection] ssh_args = -F ~/.ssh/client_1_config amazon-server-01 

Unfortunately it is not possible to define this per group, inventory or anything else specific.

Answer 2

With Ansible 2, you can set a ProxyCommand in the ansible_ssh_common_args inventory variable. Any arguments specified in this variable are added to the sftp/scp/ssh command line when connecting to the relevant host(s). Consider the following inventory group:

[gatewayed] foo ansible_host=192.0.2.1 bar ansible_host=192.0.2.2 

You can create group_vars/gatewayed.yml with the following contents:

ansible_ssh_common_args: '-o ProxyCommand="ssh -W %h:%p -q [email protected]"' 

and do the trick...
