How to find out the correct version of gitlab-ce

I used to use Gitlab on Synology 6.x

After upgrading to 7.X , it was no longer available, so i installed the docker version and got it all migrated across.

it was : postgres 12X
redis
gitlab-ce

I then rolled forward over several months, then on a roll forward it stopped working and would not restart.

i figured i 'd get back to is within a week, that was 2 years ago…

so… I still have a fully functional docker postgres database
but my gitlab docked is trashed/gone, uninstalled.

QUESTION:

  1. given i have all my GIT files & a database , HOW can i find out the last version of GITLAB-CE that was installed
  2. Is there any place in a database table with a version stamp?

there are hundreds of tables and thousands of columns…
