gha-sync-fork

A GitHub action to sync a forked repo's branch with an upstream repo's branch

Overview

The fork's changes are rebased on top of any missing commits from the upstream repository. If there are merge conflicts, this action will fail until the conflicts are manually resolved. If there are no changes between the fork and upstream, no work is done. By default, the fork's entire commit history is fetched because this action doesn't know how many new commits the fork has received.

Usage

An example workflow that runs this action:

- name: Sync my project
  uses: thebrowsercompany/gha-sync-fork
  with:
    fork_repo: myuser/project
    fork_branch: main
    upstream_repo: otheruser/project
    upstream_branch: main
