Container Service for Kubernetes:Build a CI pipeline with Argo Workflows

1. Git clone and checkout

   • Clones the Git repository and checks it out to the target branch.

   • Retrieves the commit ID and appends it as a suffix to the image tag during the build process.

2. Run Go test

   • By default, this step runs all test cases in the Git repository (a Go project).

   • The enable_test workflow parameter controls whether this step runs.

   • The Go mod cache is stored in the /pkg/mod directory on the NAS to accelerate go test and subsequent go build.

3. Build and push image

   • Uses BuildKit to build and push the container image. It also uses a registry-type cache from BuildKit Cache to accelerate the image build.

   • By default, the image tag uses the {container_tag}-{commit_id} format. When submitting the workflow, you can use a parameter to control whether to append the commit ID.

   • When the new image is pushed, the latest tag is also updated to point to it.

You can run kubectl apply -f cluster-workflow-template.yaml to deploy the template to the cluster.
