- Installing GitLab on Google Cloud Platform
Gettung started with GitLab on a Google Cloud Platform (GCP) instance is quick and easy.
There are only two prerequisites in order to install GitLab on GCP:
- You need to have a Google account.
- You need to sign up for the GCP program. If this is your first time, Google gives you $300 credit for free to consume over a 60-day period.
Once you have performed those two steps, you can create a VM.
To deploy GitLab on GCP you need to follow five simple steps:
Go to https://console.cloud.google.com/compute/instances and login with your Google credentials.
Click on Create
On the next page, you can select the type of VM as well as the estimated costs. Provide the name of the instance, desired datacenter, and machine type. Note that GitLab recommends at least 2 vCPU's and 4GB of RAM.
Click Change under Boot disk to select the size, type, and desired operating system. GitLab supports a variety of linux operating systems, including Ubuntu and Debian. Click Select when finished.
As a last step allow HTTP and HTTPS traffic, then click Create. The process will finish in a few seconds.
After a few seconds, the instance will be created and available to log in. The next step is to install GitLab onto the instance.
- Make a note of the IP address of the instance, as you will need that in a later step.
- Click on the SSH button to connect to the instance.
A new window will appear, with you logged into the instance.
Next, follow the instructions for installing GitLab for the operating system you choose, at https://about.gitlab.com/installation/. You can use the IP address from the step above, as the hostname.
Congratulations! GitLab is now installed and you can access it via your browser. To finish installation, open the URL in your browser and provide the initial administrator password. The username for this account is
These are the most important next steps to take after you installed GitLab for the first time.
By default, Google assigns an ephemeral IP to your instance. It is strongly recommended to assign a static IP if you are going to use GitLab in production and use a domain name as we'll see below.
Read Google's documentation on how to promote an ephemeral IP address.
Assuming you have a domain name in your possession and you have correctly set up DNS to point to the static IP you configured in the previous step, here's how you configure GitLab to be aware of the change:
SSH into the VM. You can easily use the SSH button in the Google console and a new window will pop up.
In the future you might want to set up connecting with an SSH key instead.
Edit the config file of Omnibus GitLab using your favorite text editor:
sudo vim /etc/gitlab/gitlab.rb
external_urlvalue to the domain name you wish GitLab to have without
We will set up HTTPS in the next step, no need to do this now.
Reconfigure GitLab for the changes to take effect:
sudo gitlab-ctl reconfigure
You can now visit GitLab using the domain name.
Although not needed, it's strongly recommended to secure GitLab with a TLS certificate. Follow the steps in the Omnibus documentation.
You need to configure the email SMTP settings correctly otherwise GitLab will not be able to send notification emails, like comments, and password changes. Check the Omnibus documentation how to do so.
GitLab can be configured to authenticate with other OAuth providers, LDAP, SAML, Kerberos, etc. Here are some documents you might be interested in reading:
