What tasks have you implemented using GitLab CI/CD in your projects?

In projects using GitLab CI/CD, I implemented automation of build, testing, and deployment of applications. For example:

• Set up pipelines for automatic code building on each commit.
• Added stages for running unit and integration tests to ensure quality.
• Organized automatic deployment to test and production servers after successful testing.
• Used caching and artifacts to speed up builds.

A simple .gitlab-ci.yml example:

stages:
  - build
  - test
  - deploy

build_job:
  stage: build
  script:
    - make build

test_job:
  stage: test
  script:
    - make test
  needs: [build_job]

deploy_job:
  stage: deploy
  script:
    - ./deploy.sh
  when: manual
  needs: [test_job]

This approach helps increase development speed and reduce errors during releases.
