GCP CI/CD Pipeline: Build Docker images after commits to a repo branch (Github)

In this article we will learn how to create a CI/CD pipeline on GCP using Cloud Build, Github, and Docker.

For this article I will be using this repository.

 

1. Create a trigger

First we would need to navigate to Code Build. Select the Triggers tab in the sidebar and Create Trigger:

GCP CI/CD pipeline using Code Build, Docker, and Github. Creating a trigger pt1

Enter the name of your trigger and select Connect new repository in the Source section:

GCP CI/CD pipeline using Code Build, Docker, and Github. Attaching Github repository to Cloud Build pt1

You will see a sidebar that will appear on the right hand side with different options for repositories supported by Cloud Build. I am using Github, so I selected the first option. Click Continue:

You will be asked to authorize Cloud Build to access your github account and repositories:

Select your github account and repository for this trigger:

GCP CI/CD pipeline using Code Build, Docker, and Github. Attaching Github repository to Cloud Build pt4

Then select the Dockerfile in the Configuration section and hit Create at the bottom of the page:

GCP CI/CD pipeline using Code Build, Docker, and Github. Creating a trigger pt2

You should see your newly created trigger with the connected repo:

2. Run trigger manually

Let's test our trigger by running it manually first.
Next to your trigger there is a button RUN:

A sidebar will popup on the right hand side asking you to confirm the details of deployment. Press Run Trigger:

I can see the new image in the Container Registry. Mine is called github.com. But it is there. The trigger is working!

3. Run trigger automatically

And finally, let's push new code to the repository and test the trigger for automatic build.

I will let reader do the code pushing.

If you want to see current or past builds, Code Build has a section called History in the sidebar on the left. It is a great to monitor builds.

When I pushed new code to my repository a new build was triggered right away and it appeared in the History section:

That's it! Thank you for reading.

Just kidding, it's a personal preference. But you can change your theme, font, etc. in your settings.

The more you know. 🌈
