All in one
no SLA on performance/availability (but we did not pay for an Ultimate or Gold version and on gitlab.com, the aaS is very good - we experienced some rarely problem time to time (e.g. after Microsoft announced they bought github, it was very slow, as lots of communities were moving to gitlab..))
CI runners are available to launch CI jobs but you still needs need cloud resources ressources to do the job (we are using our own server), no idea how much it woudl cost if it was fully externalized
no native integration so far with docker hub found (as github) BUT built-in docker registry

Focus on security aspects:

gitlab includes a docker registry and native integration with lots of open source tools
