Nginx's "listen ... http2" directive is deprecated

Summary

  • In Nginx versions 1.25.1 and above, "listen ... http2" directive is deprecated. (Link)
  • And the omnibus-gitlab package upgraded its bundled Nginx version to1.27 on GitLab 17.6. (Link)
  • However, nginx.conf file in GitLab Omnibus package is still using this directive. As this result, the following warning messages are logged in the /var/log/gitlab/nginx/error.log and /var/log/gitlab/nginx/current (See "Relevant logs" section)

Steps to reproduce

  • Install GitLab by using gitlab-omnibus
  • Run sudo gitlab-ctl tail -f
  • Run sudo gitlab-ctl restart in another command line console that is running the above command
  • Confirm the warning messages are logged into /var/log/gitlab/nginx/error.log and /var/log/gitlab/nginx/current
