Configure Gitlab Server for HTTPS

Minimal configuration steps for Gitlab Server after you install it to create TSL certificates and run over https.

Step one is to actually make the TSL certs.

IP=`hostname -I | sed 's/ //g'`
mkdir -p /etc/gitlab/ssl
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/gitlab/ssl/${IP}.key -out /etc/gitlab/ssl/${IP}.crt

Get IP:

hostname -I

Now edit /etc/gitlab/gitlab.rb. Replace SERVER with the output of IP.

external_url 'https://SERVER'
nginx['redirect_http_to_https'] = true

nginx['enable'] = true
nginx['client_max_body_size'] = '250m'
nginx['redirect_http_to_https'] = true
nginx['ssl_certificate'] = "/etc/gitlab/ssl/SERVER.crt"
nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/SERVER.key"
