default-example

Example: Getting started with a simple go app

This is a modified version of a simple example for skaffold, and contains the following features:

• building a single Go file app and with a multistage Dockerfile using local docker to build
• tagging using the default tagPolicy (gitCommit)
• deploying a single container pod using kubectl

This example contains multi-architecture images. On the development environment, the pod specification will request arm64 nodes for the autopilot cluster and run an arm64 version of the docker image. On nonproduction and production environments, the pod will run an amd64/x86 version of the image on standard clusters.

	Development	Non Production/Staging	Production
Architecture	arm64	amd64/x86	amd64/x86

To achieve multi-architecture builds and images, the examples needs to use the extended features of buildx.

Using the CI/CD Pipeline

A CI/CD pipeline was created for this application on 5-appinfra, it uses Cloud Build to build the docker image and Cloud Deploy to deploy the image to the cluster using skaffold.

1. Clone the CI/CD repository

gcloud source repos clone eab-default-example-hello-world --project=REPLACE_WITH_ADMIN_PROJECT

1. Copy the contents of this directory to the repository:

cp -r terraform-google-enterprise-application/6-appsource/hello-world/* eab-default-example-hello-world

1. Commit changes

cd eab-default-example-hello-world
git checkout -b main
git add .
git commit -m "Add code to cicd repository"
git push origin main

1. After pushing the code to the main branch, the CI (build) pipeline will be triggered on the hello-world-admin project under the common folder. You can view the results on the Cloud Build Page.

2. After the CI build succesfully runs, it will automatically trigger the CD pipeline using Cloud Deploy on the same project.

3. Once the CD pipeline succesfully runs, you should be able to see a pod named getting-started on your cluster that prints the "Hello world!" message.
