Drone with ansible plugin does not authenticate SSH key

My drone server and runner are docker containers running on a docker network, they are configured to pull the ssh_key secret from a vault instance using the extension and do so successfully.

When I try to run the above .drone.yml file the ssh test works fine with the secret ssh_key and makes a connection.

But the ansible plugin does not make a connection using the same ssh_key secret.

<***.***.***.***> ESTABLISH SSH CONNECTION FOR USER: user

fatal: [***.***.***.***]: UNREACHABLE! => {

    "unreachable": true

}

I have exhausted my options for problem solving this, the only thing I can think of that may be an issue is the tmp/privatekey***** file that is create to hold the ssh_key secret is somehow not copied in to the instanced runner or is not accessible.

And due to my setup, I can’t seem to get logs to save successfully because of the containerized nature of the system.

Any help would be appreciated.
