Build a Docker Container Image using Cloud Build

Get started with Cloud Build

This five minute tutorial will guide you through creating a container image using Cloud Build, Google’s tool for build, test, and deployment automation workloads.

Join me for a brief introduction to Google Cloud Build, as we walk through writing our first build pipeline using Google’s CI/CD platform. In the next few minutes, we shall walk through setting up and integrating a Cloud Source Repository with Cloud Build and create a job that builds and pushes a container image to Artifact Registry.

Services used in this tutorial:

• Artifact Registry
• Cloud Build
• Cloud Source Repositories

Create a Docker repository in Artifact Registry

Our initial step is be to create a repository in Artifact Registry to hold our container image. Artifact Registry can manage multiple repository formats, such as maven, npm, and in our case docker.

Type the command into a Cloud Shell session as shown below.

gcloud artifacts repositories \
     create my-docker-repo \
     --repository-format=docker \
     --location=us-central1 \
     --description="Docker repository"

Alternatively if you are using the console, head over to https://console.cloud.google.com/artifacts and hit “Create Repository”.

Create a Docker repository in Artifact Registry

And that’s all you need to do — repository created!

Write our sample application

In Cloud Shell or using the Cloud Editor make yourself a new empty working directory and create two files. You can also follow along locally if you have gcloud sdk installed.

The first file will be called hello.sh and should be a simple script:

#!/bin/sh 
echo "Hello, world!"

You will want to ensure that the script is executable chmod +x hello.sh
