Available Docker Engine Versions

The documentation states that the default Docker Engine version is 17.09.0-ce which seems incorrect as all our builds report Docker Engine Version: 18.09.6. We would like to use Docker Engine v19, but I am not clear if that is available without using machine: true and building it ourselves. Any suggestions would be appreciated.

Thanks in advance.

You’re probably seeing the client report its version. I just SSHed into a job with the default remote docker environment and everything looks accurate in regards tot he server version. It doesn’t look like we support docker v19 server options at this time. I’m not aware of a timeline I can offer for when it would be included.
