Building own github in the cloud.
I recently migrated my private repos to digital ocean and gitlab. This post is a walk through on how to do it and summarizes my experience.
Digital Ocean is a VPS provider. They have their data centers in NY, SF, Amsterdam and Singapore. Their servers are provisioned with SSD drives and have a very competitive pricing. They are a new kid in the block (launched in 2013), but they gained a lot of traction over the internet and there are a lot of success stories posted by different people. I think this is because they offer a good service, a simple UI and a competitive pricing.
Gitlab is a project witch aims at giving a github experience, but its open sourced and you can install it on-premise (although they offered a hosted solutions as well).
Without further ado, lets start the tutorial.
I went for the 10$/mo droplet, with 1024 mb memory. Gitlub recommends more, though I found that for a few projects with few users it is enough. After you create the droplet, you need to do the following.
Get the IP
Droplets -> Droplet -> Settings -> Networking -> IP Address
Set up your dns to point from
gitlab.<domain> to the IP address
of your droplet.
This is provider dependent, but most probably you need to set up an A -record from
gitlab.youdomain.com to the droplet ip address using the UI provided by the company you’ve bought your domain from.
It is not recommended to log in to your system using a root account. You should add a new user with sudo privileges.
$ ssh root@gitlab.<yourdomain> $ adduser your-user-name $ visudo # your-user-name ALL=(ALL) NOPASSWD: ALL
Its advised not to run the ssh at port 22. This will make it a bit harder for a potential.
$ vim /etc/ssh/sshd_config Port 2143 PermitRootLogin no AllowUsers your-user-name git $ service ssh restart
If we went for a droplet with 1024 mb of memory then probably we should add some swap space.
$ sudo fallocate -l 1024M /mnt/swap.img $ sudo mkswap /mnt/swap.img $ sudo swapon /mnt/swap.img $ sudo vim /etc/fstab
I have a habit of not entering my password to any service over an
insecure connection. Hence, the need to set up an https
connection. You can buy the certificates for your domain or you can
create a self signed pair (e.b. follow one of my previous posts and
Be Your Own CA). Upload the pair to
$ sudo mkdir -p /etc/nginx/ssl $ sudo cd /etc/nginx/ssl $ sudo cp ~/<file>.crt . $ sudo cp ~/<file>.key . $ sudo chown root:root *
Setup basic options for gitlab, like ssh and https details.
$ sudo vim /etc/gitlab/gitlab.rb external_url "https://gitlab.<yourdomain>/" gitlab_rails['gitlab_email_from'] = "gitlab@<yourdomain>" gitlab_rails['gitlab_support_email'] = "gitlab-support@<yourdomain>" gitlab_rails['gitlab_shell_ssh_port'] = "2143" nginx['redirect_http_to_https'] = true nginx['ssl_certificate'] = "/etc/nginx/ssl/<filename>.crt" nginx['ssl_certificate_key'] = "/etc/nginx/ssl/<filename>.key" $ sudo gitlab-ctl reconfigure $ vim config/gitlab.yml
http://gitlab.<yourdomain/ and log in using the credentials:
Set up new admin password and create a user which you’ll use later
First copy your existing repos (from your current server) to your
$ sudo cd /var/opt/gitlab/git-data/repositories/ $ sudo mv ~i/<repo.git> . $ sudo chown -R git:git <repo.git> $ sudo chmod u+rw -R <repo.git> $ sudo chmod g+rw -R <repo.git> $ sudo gitlab-rake gitlab:import:repos
That’s all. Enjoy your own github :-)
There are some online sources documenting the basic droplet and gitlab setup. Please see this:
