How to implement a CI/CD pipeline in GitLab to automate processes in repositories with similar structures?

To automate processes across multiple repositories with similar structures in GitLab, you can use a common .gitlab-ci.yml template or include shared configurations via include.

Example approach:

1. Create a separate repository with a shared template file, for example common-ci.yml.
2. In each project, include this template in .gitlab-ci.yml:

include:
  - project: 'group/common-ci'
    file: '/templates/common-ci.yml'

stages:
  - build
  - test
  - deploy

# You can override or add tasks

This way, you centralize the configuration and easily update processes across all projects.

You can also use environment variables and parameters to customize pipelines for specific projects.
