Docker 1.8.3 is available now on CircleCI

Build Environment
1

I just built and Docker 1.8.3. This release only contains security releases, so there aren’t much benefits to use in CI, but if you want to try it out, you can do so with the following in your circle.yml.

machine:
  pre:
    - echo 'DOCKER_OPTS="-s btrfs -e lxc -D --userland-proxy=false"' | sudo tee -a /etc/default/docker
    - sudo curl -L -o /usr/bin/docker 'https://s3-external-1.amazonaws.com/circle-downloads/docker-1.8.3-circleci'
    - sudo chmod 0755 /usr/bin/docker
  services:
    - docker
