# Automatically Mirror Github Repo To Your Gitea Server

## Badges

[![image pulls](https://img.shields.io/docker/pulls/jaedle/mirror-to-gitea.svg)](https://cloud.docker.com/repository/docker/jaedle/mirror-to-gitea)

## Description

This script automatically mirrors the repositories from a github-user or github-organization to your gitea server.
Once started, it will create a mirrored repository under a given token for a gitea user, completely automatically.

Example:
A github user `github-user` has public repositories `dotfiles` and `zsh-config`.
Starting the script with a gitea token for the account `gitea-user` will create the following mirrored repositories:

- github.com/github-user/dotfiles → your-gitea.url/gitea-user/dotfiles
- github.com/github-user/zsh-config → your-gitea.url/gitea-user/zsh-config

The mirror settings are default by your gitea instance.

It is also possible to mirror private repos, which can be configred here in [#parameters](#parameters). When mirroring
private repos, they will be created as private repos on your gitea server.

## Prerequisites

- A github user or organization with repositories
- Configured Gitea instance up and running
- User for Gitea with generated token (Settings -> Applications -> Generate New Token)
- Docker or Docker Compose

## Running

### Configuration

All configuration is performed through environment variables. Flags are considered `true` on `true`, `TRUE` or `1`.

| Parameter | Required | Type | Default | Description |
|-----------------------------|----------|--------|---------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| GITHUB_USERNAME | yes | string | - | The name of the GitHub user or organisation to mirror. |
| GITEA_URL | yes | string | - | The url of your Gitea server. |
| GITEA_TOKEN | yes | string | - | The token for your gitea user (Settings -> Applications -> Generate New Token). **Attention: if this is set, the token will be transmitted to your specified Gitea instance!** |
| GITHUB_TOKEN | no* | string | - | GitHub token (PAT). Is mandatory in combination with `MIRROR_PRIVATE_REPOSITORIES`. |
| MIRROR_PRIVATE_REPOSITORIES | no | bool | FALSE | If set to `true` your private GitHub Repositories will be mirrored to Gitea. Requires `GITHUB_TOKEN`. |
| SKIP_FORKS | no | bool | FALSE | If set to `true` will disable the mirroring of forks from your GitHub User / Organisation. |
| DELAY | no | int | 3600 | Number of seconds between program executions. Setting this will only affect how soon after a new repo was created a mirror may appar on Gitea, but has no affect on the ongoing replication. |
| DRY_RUN | no | bool | FALSE | If set to `true` will perform no writing changes to your Gitea instance, but log the planned actions. |
| INCLUDE | no | string | "*" | Name based repository filter (include): If any filter matches, the repository will be mirrored. It supports glob format, multiple filters can be separated with commas (`,`) |
| EXCLUDE | no | string | "" | Name based repository filter (exclude). If any filter matches, the repository will not be mirrored. It supports glob format, multiple filters can be separated with commas (`,`). `EXCLUDE` filters are applied after `INCLUDE` ones.
| SINGLE_RUN | no | bool | FALSE | If set to `TRUE` the task is only executed once. |

### Docker

```sh
docker container run \
-d \
--restart always \
-e GITHUB_USERNAME=github-user \
-e GITEA_URL=https://your-gitea.url \
-e GITEA_TOKEN=please-exchange-with-token \
jaedle/mirror-to-gitea:latest
```

This will a spin up a docker container which will run forever, mirroring all your repositories once every hour to your
gitea server.

### Docker Compose

```yaml
version: "3.3"
services:
mirror-to-gitea:
image: jaedle/mirror-to-gitea:latest
restart: unless-stopped
container_name: mirror-to-gitea
environment:
- GITHUB_USERNAME=github-user
- GITEA_URL=https://your-gitea.url
- GITEA_TOKEN=please-exchange-with-token
```

## Development

### Prerequisites

- nodejs
- [task](https://taskfile.dev)
- docker

### Execute verification

```sh
task world
```

### Running locally

Create `.secrets.rc` containing at least the following variables:

```rc
export GITHUB_USERNAME='...'
export GITHUB_TOKEN='...'
export GITEA_URL='...'
```

Execute the script in foreground:

```sh
task run-local
```
