GCP Professional Data Engineer Practice Question

Your team maintains a Java Dataflow Flex Template. Each push to the main branch must trigger Cloud Build that (1) runs Maven unit tests, (2) packages a shaded JAR, (3) builds and pushes a Docker image to Artifact Registry, and (4) creates the template specification file in a Cloud Storage bucket. All build steps must rely solely on Google-provided Cloud Builder images and follow least-privilege principles. Which cloudbuild.yaml outline satisfies these requirements?

  • steps:
- name: gcr.io/cloud-builders/docker
  args: ["build","."]
- name: gcr.io/cloud-builders/mvn
  args: ["-B","verify"]
- name: gcr.io/google.com/cloudsdktool/cloud-sdk
  args: ["dataflow","flex-template","build","gs://$PROJECT_ID-templates/myjob.json"]
images:
- "gcr.io/$PROJECT_ID/myjob:latest"

  • steps:
- name: gcr.io/$PROJECT_ID/custom/maven
  args: ["test","package"]
- name: gcr.io/cloud-builders/docker
  args: ["build","-t","us-docker.pkg.dev/$PROJECT_ID/dataflow/myjob:latest","."]
- name: gcr.io/google.com/cloudsdktool/cloud-sdk
  args: ["gsutil","cp","template.json","gs://$PROJECT_ID-templates/"]

  • steps:
- id: test
  name: gcr.io/cloud-builders/mvn:3.8.5-jdk-11
  args: ["-B","clean","verify"]
- id: package
  name: gcr.io/cloud-builders/mvn:3.8.5-jdk-11

- id: build-image
  name: gcr.io/cloud-builders/docker
