1. Clone this repo
2. Install Vagrant and VirtualBox
3. vagrant up
4. vagrant ssh

This will create a ubuntu virtual machine with gitlab running. By default, web port forwards to 8080 and ssh port forwards to 8022. You can change that in Vagrantfile.

Change config.vm.hostname = "gitlab.chenwl.com"^link to your own hostname. This will be hostname of your site.

Without a valid hostname, your mail sent to Gmail will be blocked.

Find line config.vm.network "forwarded_port", guest: 22, host: 8022^link, replace 8022 to any port you want ssh to connect.

Git client side need to configure ssh to connect to this port by default. Append following lines to ~/.ssh/config.

Host gitlab.chenwl.com # replace with your hostname
  Port 8022            # replace with your ssh port

Find line config.vm.network "forwarding_port", guest: 80, host: 8080^link, replace 8080 to any port you want your host to listen HTTP requests.
