Bug Description

When installing docker with the charm, and setting latest=true it causes intermittent failure

http://pastebin.ubuntu.com/10852805/

The byproduct of this results in a docker binary that is unable to perform any operations. The only known solution to date is to reboot the node, which is not ideal.

I have been able to reproduce this in EC2 and Azure. The current workaround given by Chuck is to remove the Docker config option of "latest=true" in the bundle and take the charm default of false. Doing so allows unit 0 and 1 of the Docker charm to be deployed.

-thanks,
Antonio

This appears to be manifesting when docker is related to flannel-docker, and the template is rendering as invalid.

Investigation continues....

Correct resolution was to guard and gate against empty config. The dockerfile was being rewritten in a race condition with no data, then not being updated after the fact. Cycling of the docker daemon with an invalid --DOCKER_OPTS was the culprit.
