Have you had experience implementing automated CI/CD processes using GitLab?

Yes, I have implemented automated CI/CD processes using GitLab. This typically involves configuring the .gitlab-ci.yml file, which describes the pipeline stages: build, test, deploy. For example, for a Python project, you can set up stages that automatically run tests on each commit and, upon successful testing, deploy the application to a server.

A simple .gitlab-ci.yml example for Python:

stages:
  - test
  - deploy

test_job:
  stage: test
  image: python:3.9
  script:
    - pip install -r requirements.txt
    - pytest

deploy_job:
  stage: deploy
  script:
    - echo "Deploying application..."
  when: on_success
  only:
    - main

This approach allows automating code quality checks and speeding up the release of new versions.
