New Docker versions for 'machine' images on CircleCI 2.0


#1

We are updating the Docker version for the machine executor on CircleCI 2.0.

You can choose the version that is used for your jobs by specifying it in .circleci/config.yml like so:

jobs:
  build:
    machine:
      image: circleci/classic:latest

If you don’t specify an image the default is circleci/classic:latest which currently has Docker 17.03.0-ce

This will be upgraded to Docker 17.06.1 on 2017-09-03 (Sunday). If you would like to continue to use 17.03.0-ce after this date you can specify: image: circleci/classic:201703-01

The full list of currently available options are:

  • circleci/classic:latest - currently Docker 17.03.0-ce will be upgraded to 17.06.1 on 2017-09-03
  • circleci/classic:edge - currently Docker 17.06.0 will be upgraded to 17.06.1 in the next 24 hours
  • circleci/classic:201703-01 is docker 17.03.0-ce
  • circleci/classic:201707-01 is docker 17.06.0-ce
