Old method started failing, this uses the new installation instructions from https://docs.docker.com/installation/ubuntulinux/

Upgrading to docker 1.8.3 seems to break builds:

# github.com SSH-2.0-libssh-0.7.0
Starting Docker...
ln: failed to create symbolic link '/sys/fs/cgroup/systemd/name=systemd': Operation not permitted
Stopping Docker...

Note: You can specify a specific docker version with the new mirror as of a week or so ago.

Here's all the versions they support:

Here's an example of locking to a specific package version in ansible:

Sweet. Added a commit that locks docker to 1.7.1. I'll test again and make sure there's no issues.

Seems like switching to the new docker build may have slowed down docker in docker.

ejholmes commented 8 years ago

Bunch of docker start timeouts after deploying this /cry.
