I am trying to make ansible connect to a machine in the local network which needs some extra options passed in SSH invocations. I tried ansible_ssh_extra_args in inventory, group vars, host vars but it is ignored. Here is an example of my inventory file:
[dev]
192.168.10.15
[dev:vars]
ansible_ssh_private_key_file="keys/deploy-myserver"
ansible_ssh_extra_args="-o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null"
ansible_ssh_user="deploy"
How can I make ansible SSH connections to a specific host use my own custom SSH options?
