github-mirror-gitea

Mirror your GitHub repositories to your Gitea server.

Introduction

A Python script to mirror all of your GitHub repositories to your Gitea server, with multiple options.

Repositories created are mirrors of the original repositories, and by default Gitea will automatically fetch them every 8 hours.

Using GitHub APIs and Gitea APIs -- especially the migrate function.

Features

There are many options to choose from:

• Mirror, or not mirror repos:
  • you own
  • you forked
  • you starred
  • you have access to as a collaborator
  • you have access to as an organization member
• Whether to remove existing repos in Gitea
• Whether to create new organizations in Gitea if {username} in {username}/{repo_name} doesn't match your GitHub username

Will also mirror your repository description and private status.

Getting Started

Prerequisites

Add the following content in your Gitea server's gitea/conf/app.ini file:

[migrations]
ALLOWED_DOMAINS = github.com, *.github.com

Configuration

All credentials are needed to be configured properly:

Key	Description
GITHUB
USERNAME	Your GitHub username
PAT	Your GitHub personal access token, needed permissions: - repo (Full control of private repositories) If you only want to mirror public repositories, grant the following only: - repo:public_repo
GITEA
USERNAME	Your Gitea username
HOST	Your Gitea hostname, starts with http:// or https://
PAT	Your Gitea personal access token, needed permissions: - repository: Read and Write If you set CREATE_ORG in options.toml to true, you also need to grant: - organization: Read and Write

You can customize these options for mirroring:

Key	Description
CONFIG
CREATE_ORG	Create a new organization in Gitea when the repository username is different from your GitHub username.
REMOVE_INEXIST_REPO	Remove all repositories in Gitea owned by the user (including those in organizations) that do not exist in GitHub.
REMOVE_EXISTING_REPO	Remove existing repositories in Gitea. This will only remove the repositories that have the same name as the repositories in GitHub. You may not want to enable this option, since Gitea will automatically fetch the mirror repositories every 8 hours.
MIRROR_OWNED	Mirror the repositories you own.
MIRROR_PRIVATE	Mirror private repositories you own.
MIRROR_FORKED	Mirror the repositories you forked.
MIRROR_STARRED	Mirror the repositories you starred.
MIRROR_COLLABORATOR	Mirror the repositories that you have collaborator access. See: https://docs.github.com/zh/rest/repos/repos#list-repositories-for-the-authenticated-user
MIRROR_ORGANIZATION	Mirror the repositories in organizations that you are a member.
RULE
MODE	whitelist or blacklist to only mirror or skip repositories that match the regex.
REGEX	Regex list.

Usage

Python script

Configure credentials.toml, and options.toml.

Clone the repository:

git clone https://github.com/katorlys/github-mirror-gitea
cd github-mirror-gitea

Install the required packages:

pip install -r requirements.txt

Run the script:

python main.py

Docker

Make sure you've modified the <> placeholders and the options before running the following command:

docker run --rm \
    -e GITHUB_USERNAME=<GITHUB_USERNAME> \
    -e GITHUB_PAT=<GITHUB_PAT> \
    -e GITEA_USERNAME=<GITEA_USERNAME> \
    -e GITEA_HOST=<GITEA_HOST> \
    -e GITEA_PAT=<GITEA_PAT> \
    -e CREATE_ORG=true \
    -e REMOVE_EXISTING_REPO=false \
    -e MIRROR_OWNED=true \
    -e MIRROR_PRIVATE=true \
    -e MIRROR_FORKED=true \
    -e MIRROR_STARRED=false \
    -e MIRROR_COLLABORATOR=false \
    -e MIRROR_ORGANIZATION=false \
    -e RULE_MODE="blacklist" \
    -e RULE_REGEX="EpicGames/.*,NVIDIAGameWorks/.*" \
    katorlys/github-mirror-gitea:latest

GitHub Actions

We've created a GitHub Action for this script. Here's an example workflow file:

name: Mirror GitHub to Gitea

on:
  workflow_dispatch:
  schedule:
    - cron: '0 0 * * *'

jobs:
  mirror:
    runs-on: ubuntu-latest

    steps:
      - name: GitHub mirror Gitea
        uses: katorlys/gitea-mirror-action@v1
        with:
          GITHUB_USERNAME: ${{ secrets.GH_USERNAME }}
          GITHUB_PAT: ${{ secrets.GH_PAT }}
          GITEA_HOST: ${{ secrets.GITEA_HOST }}
          GITEA_USERNAME: ${{ secrets.GITEA_USERNAME }}
          GITEA_PAT: ${{ secrets.GITEA_PAT }}
          CREATE_ORG: true
          REMOVE_INEXIST_REPO: false
          REMOVE_EXISTING_REPO: false
          MIRROR_OWNED: true
          MIRROR_PRIVATE: true
          MIRROR_FORKED: true
          MIRROR_STARRED: false
          MIRROR_COLLABORATOR: false
          MIRROR_ORGANIZATION: false
          MODE: 'blacklist'
          REGEX: 'EpicGames/.*,NVIDIAGameWorks/.*'

If you prefer to run our Docker image in GitHub Actions, you can use the following workflow file:

name: Mirror Github to Gitea

on:
  workflow_dispatch:

  schedule:
    - cron: 0 0 * * *

jobs:
  mirror:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout
        uses: actions/checkout@v4

      - name: Run Docker container
        run: |
          docker run --rm \
            -e GITHUB_USERNAME=${{ secrets.GH_USERNAME }} \
            -e GITHUB_PAT=${{ secrets.GH_PAT }} \
            -e GITEA_USERNAME=${{ secrets.GITEA_USERNAME }} \
            -e GITEA_HOST=${{ secrets.GITEA_HOST }} \
            -e GITEA_PAT=${{ secrets.GITEA_PAT }} \
            -e CREATE_ORG=true \
            -e REMOVE_EXISTING_REPO=false \
            -e MIRROR_OWNED=true \
            -e MIRROR_PRIVATE=true \
            -e MIRROR_FORKED=true \
            -e MIRROR_STARRED=false \
            -e MIRROR_COLLABORATOR=false \
            -e MIRROR_ORGANIZATION=false \
            -e MODE="blacklist" \
            -e RULE_REGEX="EpicGames/.*,NVIDIAGameWorks/.*" \
            katorlys/github-mirror-gitea:latest
