We’re happy to share that we recently updated our Codeship Pro build machines to Docker 17.05, the latest edge release. Additionally, our CLI is now using the latest Docker API version. You can download the latest Jet CLI release (1.18) on our download page.
Codeship Pro now uses Docker 17.05, giving you access to multi-stage builds and build arguments in the FROM instruction. You can read more about the changes: https://blog.codeship.com/docker-17-05-on-codeship-pro/
