مخرجات التعلم

  1. Explain continuous integration, delivery, and deployment.

Lab

JNR-051-LAB1 · Shop pipeline

Outcomes: 1–4 · Time: ~3 h Every PR runs the full suite (including Testcontainers) with caching; merges to main publish a tagged image; main is protected with required checks. Acceptance: a PR with a failing test cannot be merged.

Exercises (assessment: fix a broken workflow)

IDOutcomeTask
JNR-051-EX011Explain CI, continuous delivery, and continuous deployment in one sentence each, with a Shop example.
JNR-051-EX022Write a workflow that checks out, sets up Java 21 with Maven cache, and runs ./mvnw -B verify on pull requests.
JNR-051-EX032Confirm Testcontainers tests run in the workflow and find the test count in the log.
JNR-051-EX043Add a job that builds the image and pushes it to ghcr.io tagged with the commit SHA on pushes to main.
JNR-051-EX054Configure branch protection requiring a PR, one review, and the build check.
JNR-051-EX062Given a broken workflow (wrong indentation, -DskipTests, missing permissions), find and fix each defect.
أظهر الحلول
  • EX01 CI: merge often and test automatically. Delivery: every green build is releasable, a human approves. Deployment: every green build goes live automatically.
  • EX02 on: pull_request; steps actions/checkout, actions/setup-java with cache: maven, run: ./mvnw -B verify.
  • EX03 Runners have Docker; the Surefire/Failsafe summary shows "Tests run: N"; N must be above zero.
  • EX04 if the event is a push to main; permissions: packages: write; docker/login-action with GITHUB_TOKEN; docker/build-push-action with tags: ghcr.io/${{ github.repository }}:${{ github.sha }}.
  • EX05 Settings, Branches (or Rulesets): require pull request, 1 approval, status check build, block force pushes.
  • EX06 Fix YAML indentation, remove -DskipTests, add permissions: packages: write for pushing images.
  • Common mistakes (secrets printed in logs, zero tests run) are checked in the EX06 review.

الجزء العملي

Six exercises JNR-051-EX01 to EX06 plus the lab; for the assessment, fix a broken workflow. Pass: quiz 8/10, at least five exercises correct, and a failing-test PR blocked from merging.
