Can you take a project without DevOps practices (without GitLab, CI/CD) and build a standard pipeline according to all the rules of the genre?

To build a typical CI/CD pipeline from scratch in a project without DevOps practices, several key steps need to be taken:

1. Choose a version control system — if not available, implement Git.
2. Configure the repository — organize branch structure (e.g., main, develop, feature/*).
3. Select a CI/CD tool — options include GitLab CI, Jenkins, GitHub Actions, or others.
4. Automate the build — set up build scripts for the project (e.g., npm build, mvn package).
5. Automate testing — integrate unit and integration tests into the pipeline.
6. Deployment — configure automatic deployment to testing/production environments.

Example of a simple .gitlab-ci.yml for a Node.js project:

stages:
  - build
  - test
  - deploy

build_job:
  stage: build
  script:
    - npm install
    - npm run build

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

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

This pipeline provides automatic build, testing, and manual deployment, aligning with basic DevOps practices.
