Gitlab 8 with nginx proxy can't download a zip, clone a public repo as guest, can't build in CI either

Question

I think all 3 problems are related to the same issue, so I'm going to put all of them here.

Gitlab itself is working, I even managed to update it from 8.2.2 to 8.2.3. I can create projects, push my code, pull it, reclone it when I have the proper ssh key, etc.

BUT:

1. I can't download the code as zip file, got a JSON instead:

{"RepoPath":"/var/opt/gitlab/git-data/repositories/me/myrepo.git", "ArchivePrefix": "...

2. People can't clone my public repo (empty repository error).

3. CI can't build my tests:

warning: You have cloned an empty repository. Checking out 12345 as develop... fatal: reference is not a tree : 123456789mycommithash987654321

ERROR: Build failed with: exit status 1

NB: I Translated error messages from French ones.

I suppose the problem is in my Nginx configuration, but there is so much documentation I'm not sure which one is the good one: the ones with the workhorse, the ones when I have to change gitlab.rb's gitlab_git_http_server, etc.

My configuration is following:

• Gitlab 8.2.3
• Ubuntu Trusty (14.04)
• Nginx 1.8

My gitlab is hosted on a subdomain using SLL so I added a Nginx proxy

/etc/gitlab/gitlab.rb:

external_url 'https://gitlab.mydomain.com'
nginx['listen_addresses'] = ['127.0.0.1', "[::1]"]
nginx['listen_port'] = 8080 
nginx['listen_https'] = false 

/etc/nginx/site_enabled/gitlab:

server {
  listen *:80 default_server;
  listen [::]:80 ipv6only=on default_server;
  server_name gitlab.mydomain.com;
  return 301 https://$server_name$request_uri;

  access_log  /var/log/nginx/gitlab_access.log;
  error_log   /var/log/nginx/gitlab_error.log;
}

server{
  # listen 443 ssl;
  listen 0.0.0.0:443 ssl default_server;
  listen [::]:443 ipv6only=on ssl default_server; 
  server_name gitlab.mydomain.com;
  server_tokens off;

  location /{
    proxy_pass http://localhost:8080;
    proxy_redirect off;
    proxy_set_header    Host                $http_host;
    proxy_set_header    X-Real-IP           $remote_addr;
    proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;
    proxy_set_header    X-Forwarded-Proto   $scheme;
  }

  location ~ ^/(assets)/ {
    root /opt/gitlab/embedded/service/gitlab-rails/public;
    gzip_static on; # to serve pre-gzipped version
    expires max;
    add_header Cache-Control public;
  }

  client_max_body_size 250m;

  # ...
  # A lot a of SSL stuff (HSTS, OCSP, dhparam, etc)
  # ...

  access_log  /var/log/nginx/gitlab_access.log;
  error_log   /var/log/nginx/gitlab_error.log;
  
  error_page 502 /502.html;

UPDATE :

Just upgraded Gilab to 8.3.0.

Git a 502 now.

Applying : https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/update/8.2-to-8.3.md.

We'll see.

UPDATE 2:

Did not finish instructions after all, stop everything and restarting everything twice (Gitlab and Nginx) Finally managed to get the thing working.

Still same problems with CI/Zip/PublicCloning tough.

UPDATE 3:

Just update to 8.2.3 apt-get update apt-get install gitlab-ce

502.

restart nginx gitlab-ctl restart

gitlab-rake gitlab:app:check

If someone can lead me to the proper documentation or changes to be made that would be awesome.

Answer 1

It looks as though downloading of ZIP-Files is now handled by the gitlab-workhorse.

For that there's some extra stuff in the nginx-configfile. You might want to have a look at https://gitlab.com/gitlab-org/gitlab-ce/blob/master/lib/support/nginx/gitlab where there is a section

upstream gitlab-workhorse {
  server unix:/home/git/gitlab/tmp/sockets/gitlab-workhorse.socket fail_timeout=0;
}

and a

proxy_pass http://gitlab-workhorse;

at the end of the configuration.

I'm currently digging into the same issue and will report back, when I've solved it.
