Tell about your experience with CI/CD: what did you do, what tools did you use?

In my experience with CI/CD, I have set up automated build, testing, and deployment of applications. I used tools like Jenkins, GitLab CI, and GitHub Actions.

The main tasks I performed:

• Automating project builds upon commits to the repository.
• Running unit and integration tests to ensure code quality.
• Deploying to testing and production environments with minimal downtime.
• Setting up notifications about build and deployment statuses.

An example of a simple pipeline in GitLab CI:

stages:
  - build
  - test
  - deploy

build_job:
  stage: build
  script:
    - ./gradlew assembleRelease

test_job:
  stage: test
  script:
    - ./gradlew test

deploy_job:
  stage: deploy
  script:
    - ./deploy.sh
  only:
    - master

This approach allows for quick error detection and speeds up the release of new versions.
