Problem to solve

Semantic versioning and release notes are best practices for a release manager. Today, we cannot automatically increment versions or generate releases. This would be especially helpful as an extension of AutoDevOps Templates.

AutoDevops would benefit from using auto-releases as a part of their CICD lifecycle and generation of auto-changelogs. This would be a great getting started with GitLab releases that have a straight forward commits to master strategy that indicates.

Intended users

• Rachel (Release Manager)
• Sasha (Software Developer)

User experience goal

As a developer, I want my AutoDevops template to auto-increment versions and generate releases.

Proposal

Integrate Semantic Release (https://semantic-release.gitbook.io/semantic-release/recipes/recipes/gitlab-ci), into AutoDevops template.

Extend the Auto-DevOps.gitlab-ci.yml template to include the Auto Release job by default.

stages:
  - release

semantic-release:

  stage: release

    - npm install -g semantic-release @semantic-release/gitlab @semantic-release/exec
