Ansible won't let me connect through SSH

Question

I\'m trying to connect from one server to another. In fact I\'m trying to connect to my host OS (CoreOS) from within a docker container. I have set up a RSA key and it works lik

Answer 1

I found here that one of the reasons why ssh pipelining fails in docker is a bug when using overlay storage driver. Then a quick fix is to change directory of control path. In /etc/ansible/ansible.cfg add

[ssh_connection] control_path_dir=/dev/shm/ansible_control_path

Answer 2

I had the same problem with ansible running in a docker container on a coreOS host. With the help of this thread, i could follow it up to the -O ControlPath option. Switching off acceleration didn't help for me though. Changing the ssh_args= line to empty string did the trick for me.

Answer 3

Turning off the accelerate option did the trick. So in /etc/ansible/ansible.cfg I added accelerate: false and commented out the other accelerate options.

Seems to work. Thanks a lot Thomasleveil
