How to Load Gitlab Inside an Iframe

· by Victor Mendonça · Read in about 2 min · (301 words) ·

So you are trying to load GitLab inside another page via iframe, and you are not able to. Due to security reasons, this is default behavior for GitLab, and as per the project (see issue 2347, this will not change, and I agree).

However for some internal users this might not be the best approach, so here’s how to enable it.

Browse to your install directory and go to your ‘nginx’ folder. If you are not sure where it is, with your GitLab instance running, use the following command (assuming you are using port 8888).

# netstat -anp | grep 8888
tcp        0      0      *                   LISTEN      19761/nginx

Now use the PID to find where ‘nginx’ is running:

# ps -ef | grep 19761
root     19761  1029  0 13:12 ?        00:00:00 nginx: master process /opt/gitlab/embedded/sbin/nginx -p /var/opt/gitlab/nginx

Browse to the config folder and edit the ‘gitlab-http.conf’

# cd /var/opt/gitlab/nginx/conf

# vim gitlab-http.conf

Add the line proxy_hide_header X-Frame-Options;in thelocation /` code block

 location / {
     ## Serve static files from defined root folder.
     ## @gitlab is a named location for the upstream fallback, see below.
     try_files $uri $uri/index.html $uri.html @gitlab;

   proxy_hide_header X-Frame-Options;

Comment the line proxy_hide_header X-Frame-Options; if present

location @gitlab {
    ## If you use HTTPS make sure you disable gzip compression
    ## to be safe against BREACH attack.

    ## Some requests take more than 30 seconds.
    proxy_read_timeout      300;
    proxy_connect_timeout   300;
    proxy_redirect          off;

    proxy_set_header   X-Forwarded-Proto $scheme;
    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-Frame-Options   SAMEORIGIN;
    #proxy_hide_header X-Frame-Options;

    proxy_pass http://gitlab;

Restart GitLab

# gitlab-ctl restart
ok: run: logrotate: (pid 31748) 1s
ok: run: nginx: (pid 31752) 0s
ok: run: postgresql: (pid 31757) 1s
ok: run: redis: (pid 31766) 0s
ok: run: sidekiq: (pid 31774) 0s
ok: run: unicorn: (pid 31786) 0s

That should be it!!!
