• To install Docker CE, you need a maintained version of CentOS 7. Archived versions aren’t supported or tested.

  The centos-extras repository must be enabled. This repository is enabled by default, but if you have disabled it, you need to re-enable it.

  The overlay2 storage driver is recommended.
