How is process automation carried out using GitLab CI/CD tools?

GitLab CI/CD allows automating the processes of development, testing, and deployment of applications by describing pipelines in the .gitlab-ci.yml file.

Main automation steps:

• Defining stages, such as build, test, deploy.
• Configuring jobs that run at specific stages.
• Automatically triggering the pipeline on events, such as a push to the repository.
• Using runners — agents that execute tasks.

Example of a simple .gitlab-ci.yml:

stages:
  - build
  - test
  - deploy

build_job:
  stage: build
  script:
    - echo "Building the project..."

test_job:
  stage: test
  script:
    - echo "Running tests..."

deploy_job:
  stage: deploy
  script:
    - echo "Deploying application..."
  when: manual

Thus, GitLab CI/CD helps automate repetitive tasks, reducing the likelihood of errors and speeding up the development process.
