Ansible with a bastion host / jump box? -


this question has answer here:

i'm i've seen feature in ansible documentation can tell connect hosts first needs tunnel through dmz host. can't seem find documentation outside of debates on mailing lists.

i'm aware of hacking in ssh config on page http://alexbilbie.com/2014/07/using-ansible-with-a-bastion-host/ that's overcomplicated kludge extremely common requirement in kind of mildly regulated environment.

is there way without using custom ssh config includes , voodoo netcat sorcery?

with ansible 2, built-in option:

how configure jump host access servers have no direct access to?

with ansible 2, can set proxycommand in ansible_ssh_common_args inventory variable. arguments specified in variable added sftp/scp/ssh command line when connecting relevant host(s). consider 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 following contents:

ansible_ssh_common_args: '-o proxycommand="ssh -w %h:%p -q user@gateway.example.com"'

ansible append these arguments command line when trying connect hosts in group gatewayed. (these arguments used in addition ssh_args ansible.cfg, not need repeat global controlpersist settings in ansible_ssh_common_args.)

note ssh -w available openssh 5.4 or later. older versions, it’s necessary execute nc %h:%p or equivalent command on bastion host.
