Its good to know that you can always upgrade your CE instance to EE just by installing the EE packages ontop of the CE.

Installation

Ansible Role

Docker CE Image

Docker EE Image

GitLab uses their Omnibus GitLab package to group the services needed to host a GitLab instance without creating confusing configuration scenarios.

GitLab can be hosted on a Pi which means you can do some tweaking to improve performance or save some resources on your host. Some options would be splitting the DBs from the host and reducing running processes. Both are described and documented in the link above.
