github batch updater

This application is a rough tool to help with mundane tasks like updating same GH workflow in multiple repos.

It is able to fetch files from multiple repositories, replace some strings and create a PR with the changes. You can also use yq expressions to modify the yaml files.

Installation

go install github.com/kolah/github-batch-updater/cmd/gbu@latest

Usage

In order to interact with the GitHub API, you need to set the GITHUB_PERSONAL_ACCESS_TOKEN env variable with a personal access token. The token should have the repo scope. If you want to interact with GitHub workflows, you need to add the workflow scope.

gbu run script.yml

Example script

# if not provided, it will be the default branch of the repository
