## Redirects all HTTP traffic to the HTTPS host
server {
  ## Either remove "default_server" from the listen line below,
  ## or delete the /etc/nginx/sites-enabled/default file. This will cause gitlab
  ## to be served if you visit any address that your server responds to, eg.
  ## the ip address of the server (http://x.x.x.x/)
  listen 0.0.0.0:80;
  listen [::]:80 ipv6only=on;

  ## Replace this with something like pages.gitlab.com
  server_name ~^.*\.YOUR_GITLAB_PAGES\.DOMAIN$;
  server_tokens off; ## Don't show the nginx version number, a security best practice
