Using Ansible on Ubuntu to stop+rm+run docker containers; getting an ssh error regarding docker socket

Archives Ansible Project
1

Hi;

  I have a Mac Book Air running Yosemite that hosts a Ubuntu 14.04
(server) VirtualBox guest OS.

  I'm using docker 1.4.0 on the Ubuntu guest.

  I'm using Ansible 1.8.2 and I'm using the Ansible docker module.

  I'm running the ansible playbook as myself (kwolcott, not root) and
trying to connect with the developer account on the Ubuntu guest OS
using a supplied server.pem ssh key, where the contents of therelated
server.pem.pub file is in the developer's .ssh/authorized_keys file.

  The interesting thing is that this fails on my other Mac (Mac Book
Pro) but works fine on a colleague's mac using the same scripts and
the same vm (from an external ova image).

  I previously was just getting an ssh failure, but this is what I get
when I add "-vvvv" to the ansible playbook call line in the supporting
bash script.

  Here are the results from the "Gathering Facts" section of my
ansible playbook run on the Mac trying to stop+rm+start two docker
containers hosted on the VirtualBox Ubuntu guest OS:

Hello again;

  I tried a number of things and ran the script again and this time I
got different output (enclosed below).

  Is there a bug in Ansible with ssh?

  Is there a bug in the Ansible docker module?

  Do I have an improperly configured/installed Ansible?

  Is Mac OS X (Yosemite), Ansible 1.8.2, VirtualBox 4.3.20, Ubuntu
14.04 (VirtualBox guest) and docker 1.40 incompatible with each other
somehow?

I’m getting the same error as well but can’t work out what the problem is. I’m running my playbook against an Ubuntu server on AWS and docker has been installed and in the path. So not sure why ansible thinks it can’t find it. hope we get soe clarification on whether this is a bug with the module or some missing config on our part.

Since there are not many reports of this problem, I don't think it is
a general bug, specially since the involved technologies are in
widespread use.
