Docker doesn't correctly print it's version. The version may be identified by using eopkg, but correct operation should have the version displayed by the docker executable also.
Problematic command:
$ docker --version Docker version unknown-version, build 1caf76ce6b
Version installed:
$ eopkg info docker Installed package: Name : docker, version: 17.11.0, release: 11 Summary : Open source application container engine Description : Docker is an open source project to pack, ship and run any application as a lightweight container. Docker containers are both hardware-agnostic and platform-agnostic. This means they can run anywhere, from your laptop to the largest cloud compute instance and everything in between - and they don't require you to use a particular language, framework or packaging system. That makes them great building blocks for deploying and scaling web apps, databases, and backend services without depending on a particular stack or provider.
