Share gitlab-ci.yml between projects

Question

We are thinking to move our ci from jenkins to gitlab. We have several projects that have the same build workflow. Right now we use a shared library where the pipelines are

Answer 1

GitLab 11.7 introduces new include methods, such as include:file: https://docs.gitlab.com/ee/ci/yaml/#includefile

include:
  - project: 'my-group/my-project'
    ref: master
    file: '/templates/.gitlab-ci-template.yml'

This will allow you to create a new project on the same GitLab instance which contains a shared .gitlab-ci.yml.
