Trying to move from gitlab source installation to omnibus failed miserable. Despite spending a whole day, I didn’t got it running. Obstacles have been the migration of the complex setup and disk space consumption. It is just a small VM running the klostercluster Web page.
Just by accident I found a review of gogs. Looks very nice, is simple to setup, well, the apache2 proxying with sub-url took some time, but beside this it was an easy exercise. The set of features is fully sufficient and the whole thing is much more stable and much much more faster. Let’s see if this promising start develops into a long-term experience.
