Docker-gitlab: Cannot create/update cross-fork MRs

[xasx]

Pulling the issue from GitLab to here after investigation:

https://gitlab.com/gitlab-org/gitlab-ce/issues/51176

Summary

I have encounter problems when approaching several cross-fork actions belonging to my usual workflow:

• Opening a merge request from a branch within my fork towards the master of the upstream repo, this results in 503 errors.
• Updating existing cross-fork merge request with new commits, they do not show up in the merge requests, neither do the diffs.
  However, the branch in the fork shows the newly added commit.

The issues happened first after upgrading from 11.1.4 to 11.2.3

Steps to reproduce

1. Use a fresh setup from this variant, then either of the following:

---

1. Have a repo forked
2. Open a merge request from a branch with new commits that forked repo into the upstream repo

---

1. Have a forked repo
2. Create a new branch without changes
3. Create a cross-fork MR for this branch into upstream repo
4. Add commits to this branch

Test run (<5min)

• [opt] remove /srv/docker
• [opt] docker-compose down
• git checkout <tag>
• docker-compose pull
• docker-compose up
• wait for boot, goto localhost:10080, set root password, login
• create group
• create project
• create README
• fork repo
• create branch
• edit readme
• commit
• create merge request

Works for 11.1.4

Does not work anymore for 11.2.0

Logs show some

gitlab_1      | 2018-09-07 16:52:58,216 INFO reaped unknown pid 1570

Which weren't present when it used to work

We have the same problem. We are using version 11.2.3

Seen another similar issue https://gitlab.com/gitlab-org/gitlab-ce/issues/50691

Intermediate fix

docker-compose exec gitlab bash
ln -s $(which gitaly-ssh) /

Apparently gitaly(-ssh) needs a bit more caring :wink:

Hi @xasx, thanks for the fix. Works :-)

@xasx Hi! I tried your method 1) i used command docker exec -ti (id container) bash for access to docker container 2)found gitaly-ssh file 3)used the command ln -s (file gitaly-ssh directory) / and restart docker container. Your method did not work.

@Uporaba1 which exact problem do you encounter?

Have you seen the specific error message in the log files, as linked in the GitLab issue?

[Uporaba1]

@xasx After the ln -s command and reboot docker, the rebase didn't work. No i didn't see error message in the log files.

@xasx in gitlab issue i see this:
