gitlab-auto-mr 1.0.1

A simple tool for automatically creating merge requests in GitLab

GitLab Auto MR

This is a simple Python script that allows you create MR in GitLab automatically. It is intended to be used in CI/CD as a Docker image. However you can use it as a separate Python library if you would like. An example CI using this can be found here.

It is based on the script and idea of Riccardo Padovani, which he introduced with his blog post How to automatically create new MR on Gitlab with Gitlab CI.

This package was intended to be used by GitLab CI hence using environments provided by the GitLab CI. You can however use it as a CLI tool if you would like.

Usage

First you need to create a personal access token, more information here. With the scope api, so it can create the MR using your API.

  pip install gitlab-auto-mr
  gitlab_auto_mr --help

GitLab CI

GITLAB_PRIVATE_TOKEN Set a secret variable in your GitLab project with your private token. Name it GITLAB_PRIVATE_TOKEN (CI/CD > Environment Variables). This is necessary to raise the Merge Request on your behalf. More information click here. An example CI using this can be found here.

Add the following to your .gitlab-ci.yml file:

stages:
  - open

open_merge_request:
  image: registry.gitlab.com/gitlab-automation-toolkit/gitlab-auto-mr
  before_script: [] # We do not need any setup work, let's remove the global one (if any)
  variables:
    GIT_STRATEGY: none # We do not need a clone of the GIT repository to create a Merge Request
  stage: open
  only:
    - /^feature\/*/ # We have a very strict naming convention
  script:
    - gitlab_auto_mr
