CI CD Github Actions

CI/CD and GitHub Actions

Purpose: Author reproducible CI workflows that enforce quality gates (build, tests, lint, security) and automate release steps.

Key topics:

• Workflow templates for PR validation and release pipelines
• Artifact build and publish steps (Maven/Gradle, Docker images)
• Security and dependency scanning integration (Snyk, oss-audit)
• Policy gates and required checks configuration

Required inputs:

• Repository build matrix, required checks list

Outputs:

• Reusable workflow YAMLs, status badge, CI runbooks

Success criteria:

• CI workflows run on PRs and produce deterministic results
• Blocking gates configured for tests and security scans

Quick GitHub Actions PR-validation snippet (example):

name: PR Validation
on: [pull_request]
jobs:
	build:
		runs-on: ubuntu-latest
		strategy:
			matrix:
				java: [17, 21]
		steps:
			- uses: actions/checkout@v4
			- uses: actions/setup-java@v4
				with:
					java-version: ${{ matrix.java }}
			- name: Cache Maven
				uses: actions/cache@v4
				with:
					path: ~/.m2/repository
					key: ${{ runner.os }}-maven-${{ hashFiles('**/pom.xml') }}
			- name: Build & Test
				run: mvn -B -DskipTests=false verify
			- name: Run Snyk
				if: success()
				run: snyk test || true

Best practices:

• Keep PR workflows fast: run unit tests and quick integration smoke tests.
• Run longer integration tests and heavy scans on schedule or on-demand pipeline.
• Use caching for Maven/Gradle artifacts to speed up CI.

Security scanning integration:

• snyk test and snyk monitor can be included as steps; allow snyk to fail the job only on policy severity levels you enforce.
• Add dependency-check or oss-audit as supplementary scans.

Release & artifact publishing:

• Build Docker images in CI, tag with PR/branch identifiers, push to private registry in release pipelines.
• Publish Maven artifacts to repository manager (Nexus/Artifactory) from release workflows.

Policy gates:

• Configure branch protection rules to require passing checks: build, unit tests, security scan, and at least one approving review.

CI runbooks & troubleshooting:

• Document common failures (flaky tests, environment variables) and recommended remediation steps in .github/ci/README.md.
