docker version returns:

Engine:

Go version: go1.9.4

Git commit: 7390fc6

Experimental: false

I want to install jupyterhub which requires docker engine 1.12.0, but I doubt that Version 17.12.1 is not the the engine version. How can I get the engine version?

Docker Engine versioning changed from February to March 2017.

The last version in the old format is 1.13.1 (2017-02-08). The first stable version of the community edition in the new format is 17.03.0-ce (2017-03-01).

So, 17.12.1 is newer than 1.12.0 and they both refer to the Docker Engine.

You can check the old versions here: https://docs.docker.com/release-notes/docker-engine/ and the new versions here: https://docs.docker.com/release-notes/docker-ce/.
