Hey, I’m running ansible(1.6.1) on a ubuntu 12.04 and trying to start containers through the ansible docker module. The Docker host machine is a 14.04 with Docker 0.9.1 and docker-py. Building the image through ansible worked like a charm: - name: check or build images docker\_image: path=/root/docker/ap53 name=th/ap53 state=present But when i use the docker module: - name: Starting containers docker: image=th/ap53 name=n-ap33 state=present This is what i get: > ESTABLISH CONNECTION FOR USER: root > REMOTE\_MODULE docker image=th/ap53 name=n-ap33 state=present > EXEC [‘ssh’, ‘-C’, ‘-tt’, ‘-vvv’, ‘-o’, ‘ControlMaster=auto’, ‘-o’, ‘ControlPersist=60s’, ‘-o’, ‘ControlPath=/root/.ansible/cp/ansible-ssh-%h-%p-%r’, ‘-o’, ‘StrictHostKeyChecking=no’, ‘-o’, ‘KbdInteractiveAuthentication=no’, ‘-o’, ‘PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey’, ‘-o’, ‘PasswordAuthentication=no’, ‘-o’, ‘ConnectTimeout=10’, ‘n-dh04’, “/bin/sh -c ‘mkdir -p $HOME/.ansible/tmp/ansible-tmp-1401183631.25-7365119312985 && echo $HOME/.ansible/tmp/ansible-tmp-1401183631.25-7365119312985’”] > PUT /tmp/tmp4i84VW TO /root/.ansible/tmp/ansible-tmp-1401183631.25-7365119312985/docker > EXEC [‘ssh’, ‘-C’, ‘-tt’, ‘-vvv’, ‘-o’, ‘ControlMaster=auto’, ‘-o’, ‘ControlPersist=60s’, ‘-o’, ‘ControlPath=/root/.ansible/cp/ansible-ssh-%h-%p-%r’, ‘-o’, ‘StrictHostKeyChecking=no’, ‘-o’, ‘KbdInteractiveAuthentication=no’, ‘-o’, ‘PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey’, ‘-o’, ‘PasswordAuthentication=no’, ‘-o’, ‘ConnectTimeout=10’, ‘n-dh04’, u"/bin/sh -c ‘LC\_CTYPE=en\_US.UTF-8 LANG=en\_US.UTF-8 /usr/bin/python /root/.ansible/tmp/ansible-tmp-1401183631.25-7365119312985/docker; rm -rf /root/.ansible/tmp/ansible-tmp-1401183631.25-7365119312985/ \>/dev/null 2\>&1’"] > failed: [n-dh04] =\> {“failed”: true, “item”: “”, “parsed”: false} > invalid output was: Traceback (most recent call last): > File “/root/.ansible/tmp/ansible-tmp-1401183631.25-7365119312985/docker”, line 1922, in > main() > File “/root/.ansible/tmp/ansible-tmp-1401183631.25-7365119312985/docker”, line 691, in main > containers = manager.create\_containers(1) > File “/root/.ansible/tmp/ansible-tmp-1401183631.25-7365119312985/docker”, line 546, in create\_containers > if docker.utils.compare\_version(‘1.10’, self.client.version()[‘ApiVersion’]) \< 0: > KeyError: ‘ApiVersion’ > OpenSSH\_5.9p1 Debian-5ubuntu1.4, OpenSSL 1.0.1 14 Mar 2012 > debug1: Reading configuration data /etc/ssh/ssh\_config > debug1: /etc/ssh/ssh\_config line 19: Applying options for \* > debug1: auto-mux: Trying existing master > debug2: fd 3 setting O\_NONBLOCK > debug2: mux\_client\_hello\_exchange: master version 4 > debug3: mux\_client\_request\_forwards: requesting forwardings: 0 local, 0 remote > debug3: mux\_client\_request\_session: entering > debug3: mux\_client\_request\_alive: entering > debug3: mux\_client\_request\_alive: done pid = 1417 > debug3: mux\_client\_request\_session: session request sent > debug1: mux\_client\_request\_session: master session id: 2 > debug3: mux\_client\_read\_packet: read header failed: Broken pipe > debug2: Received exit status from master 0 > Shared connection to n-dh04 closed. > > FATAL: all hosts have already failed – aborting If i dont use the docker module but run it as a command: - name: Start ap53 container command: docker run -d -t -name n-ap53-2 th/ap53 Everything works fine. So there’s something strange in the docker api, anyone bumped into this issue? ---

Hi Thomas, Check out 1.6.2 since it contains some docker fixes. Also, I seem to remember his issue being a result of old dockerd versions. Upgrade docker to .10 or greater; I think this problem is in .9 and below. IMHO docker-py should handle backwards compatibility, but doesn’t, and that’s why we see this problem. ---

Yes, this version should be fixed in 1.6.2 and the devel branch on github. Please let us know if you’re still seeing any problems related to this. Thanks! ---

Thx, it worked 🙂 I have another issue tho. In the docker\_image module i’ve set the state=preset: > - name: check or build images > docker\_image: path=/root/docker/{{ item.ap\_name }} name={{ item.author }}/{{ item.ap\_name }} state=present > with\_items: docker\_vars > register: doc\_images Which should “Build docker image if required” but every time i run it creates a new one and therefor makes a “change” which i presume is what the state=build is for. (Now running Ansible(1.6.2) on ubuntu 14.04) ---

Oh boy. Docker currently changes API signatures about every week. We are doing what we can 🙂 If you would like to help it would be welcome.
