(set in GitLab UI → Settings → CI/CD → Variables) can be masked or protected for specific branches. 3.2 Conditional Logic with rules The only/except keywords are deprecated in favor of rules .

test_job: stage: test script: - npm run test

GitLab then shows a dashboard of deployments, and you can roll back from the UI. For secure cluster access, use the GitLab Agent instead of storing kubeconfig . automating devops with gitlab ci/cd pipelines read online

Introduction: The Shift from Manual to Automated DevOps In the early days of software development, deploying code was a manual, nerve-wracking affair. System administrators would SSH into servers, pull code from repositories, run build commands, and restart services. This process was error-prone, slow, and unscalable.

curl --request POST --form "token=$CI_JOB_TOKEN" --form "ref=main" "https://gitlab.com/api/v4/projects/123/trigger/pipeline" This allows external systems (monitoring, chatops) to start pipelines. DevOps automation must include security. GitLab provides native security scanning. SAST (Static Application Security Testing) Add to your pipeline: (set in GitLab UI → Settings → CI/CD

include: - template: Security/Secret-Detection.gitlab-ci.yml These security jobs run automatically, enforcing "shift-left" security. Environments Track deployments by defining environments:

build: stage: build-image image: docker:20.10.16 services: - docker:20.10.16-dind script: - docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY - docker build -t $IMAGE_TAG . - docker push $IMAGE_TAG only: - main For secure cluster access, use the GitLab Agent

include: - template: Security/SAST.gitlab-ci.yml GitLab automatically runs SAST scanners for your language (Python, Java, Go, etc.) and shows vulnerabilities in merge requests. include: - template: Security/Dependency-Scanning.gitlab-ci.yml Secret Detection Prevents accidental commits of passwords/keys:
