Can you describe the most memorable project where you applied continuous integration and deployment practices?

In one of the projects, I participated in developing a web application where we implemented continuous integration (CI) and continuous deployment (CD) practices.

Key points:

• Used GitLab CI for automatic build and test runs with each commit.
• Upon successful tests, a Docker image was automatically built and published to the registry.
• Then, the update was automatically deployed to a test environment for verification.
• After manual approval, changes were moved to production through an automated pipeline.

This approach significantly reduced the release time of new versions, improved quality through automated tests, and lowered deployment risks.

Example of a simple .gitlab-ci.yml for CI/CD:

stages:
  - build
  - test
  - deploy

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

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

deploy:
  stage: deploy
  script:
    - ./deploy.sh
  when: manual

This approach helps maintain stability and development speed.
