|
A simple, lightweight Mastodon bot that automatically posts updates from RSS feeds to the Fediverse. Built with Python and designed to run seamlessly in Docker with multiarch support (amd64 & arm64).
|
|
|
|
## Features
|
|
|
|
- Automatically monitors RSS/Atom feeds and posts new items to Mastodon
|
|
- Persistent state tracking to avoid duplicate posts
|
|
- Configurable post visibility (public, unlisted, private, direct)
|
|
- Lightweight Alpine-based Docker image
|
|
- Multiarch support (amd64 & arm64) for broad compatibility
|
|
- Continuous monitoring with configurable check intervals
|
|
|
|
## Quick Start
|
|
|
|
### Using Docker (Recommended)
|
|
|
|
The easiest way to run Masto-RSS is using the pre-built multiarch Docker images available on both Docker Hub and GitHub Container Registry.
|
|
|
|
#### Pull from Docker Hub
|
|
|
|
```bash
|
|
docker pull amitserper/masto-rss:latest
|
|
```
|
|
|
|
#### Pull from GitHub Container Registry
|
|
|
|
```bash
|
|
docker pull ghcr.io/aserper/masto-rss:latest
|
|
```
|
|
|
|
#### Run the Bot
|
|
|
|
```bash
|
|
docker run -d \
|
|
--name masto-rss-bot \
|
|
-e MASTODON_CLIENT_ID="your_client_id" \
|
|
-e MASTODON_CLIENT_SECRET="your_client_secret" \
|
|
-e MASTODON_ACCESS_TOKEN="your_access_token" \
|
|
-e MASTODON_INSTANCE_URL="https://mastodon.social" \
|
|
-e RSS_FEED_URL="https://example.com/feed.xml" \
|
|
-e TOOT_VISIBILITY="public" \
|
|
-e CHECK_INTERVAL="300" \
|
|
-v /path/to/state:/state \
|
|
amitserper/masto-rss:latest
|
|
```
|
|
|
|
> **Important:** Use a bind mount for `/state` to persist the list of processed feed items across container restarts.
|
|
|
|
### Using Docker Compose
|
|
|
|
Create a `docker-compose.yml`:
|
|
|
|
```yaml
|
|
version: '3.8'
|
|
|
|
services:
|
|
masto-rss:
|
|
image: amitserper/masto-rss:latest
|
|
# Or use GHCR: ghcr.io/aserper/masto-rss:latest
|
|
container_name: masto-rss-bot
|
|
restart: unless-stopped
|
|
environment:
|
|
MASTODON_CLIENT_ID: "your_client_id"
|
|
MASTODON_CLIENT_SECRET: "your_client_secret"
|
|
MASTODON_ACCESS_TOKEN: "your_access_token"
|
|
MASTODON_INSTANCE_URL: "https://mastodon.social"
|
|
RSS_FEED_URL: "https://example.com/feed.xml"
|
|
TOOT_VISIBILITY: "public"
|
|
CHECK_INTERVAL: "300"
|
|
volumes:
|
|
- ./state:/state
|
|
```
|
|
|
|
Then run:
|
|
|
|
```bash
|
|
docker-compose up -d
|
|
```
|
|
|
|
## Configuration
|
|
|
|
All configuration is done via environment variables:
|
|
|
|
| Variable | Description | Required | Example |
|
|
|----------|-------------|----------|---------|
|
|
| `MASTODON_CLIENT_ID` | Mastodon application client ID | Yes | `abc123...` |
|
|
| `MASTODON_CLIENT_SECRET` | Mastodon application client secret | Yes | `xyz789...` |
|
|
| `MASTODON_ACCESS_TOKEN` | Mastodon access token | Yes | `token123...` |
|
|
| `MASTODON_INSTANCE_URL` | URL of your Mastodon instance | Yes | `https://mastodon.social` |
|
|
| `RSS_FEED_URL` | URL of the RSS/Atom feed to monitor | Yes | `https://example.com/feed.xml` |
|
|
| `TOOT_VISIBILITY` | Post visibility level | Yes | `public`, `unlisted`, `private`, or `direct` |
|
|
| `CHECK_INTERVAL` | Seconds between feed checks | Yes | `300` (5 minutes) |
|
|
|
|
### Getting Mastodon API Credentials
|
|
|
|
1. Log into your Mastodon instance
|
|
2. Go to **Settings** → **Development** → **New Application**
|
|
3. Give it a name (e.g., "RSS Bot")
|
|
4. Set scopes to `write:statuses`
|
|
5. Save and copy the client ID, client secret, and access token
|
|
|
|
## Building from Source
|
|
|
|
### Build Locally
|
|
|
|
```bash
|
|
git clone https://github.com/aserper/masto-rss.git
|
|
cd masto-rss
|
|
docker build -t masto-rss .
|
|
```
|
|
|
|
### Build Multiarch Images
|
|
|
|
```bash
|
|
# Set up buildx
|
|
docker buildx create --use
|
|
|
|
# Build for both architectures
|
|
docker buildx build \
|
|
--platform linux/amd64,linux/arm64 \
|
|
-t yourusername/masto-rss:latest \
|
|
--push \
|
|
.
|
|
```
|
|
|
|
## Running Without Docker
|
|
|
|
If you prefer to run the bot directly with Python:
|
|
|
|
```bash
|
|
# Clone the repository
|
|
git clone https://github.com/aserper/masto-rss.git
|
|
cd masto-rss
|
|
|
|
# Install dependencies
|
|
pip install -r requirements.txt
|
|
|
|
# Set environment variables
|
|
export MASTODON_CLIENT_ID="your_client_id"
|
|
export MASTODON_CLIENT_SECRET="your_client_secret"
|
|
export MASTODON_ACCESS_TOKEN="your_access_token"
|
|
export MASTODON_INSTANCE_URL="https://mastodon.social"
|
|
export RSS_FEED_URL="https://example.com/feed.xml"
|
|
export TOOT_VISIBILITY="public"
|
|
export CHECK_INTERVAL="300"
|
|
|
|
# Run the bot
|
|
python main.py
|
|
```
|
|
|
|
> **Note:** When running without Docker, the bot stores its state in `/state/processed_entries.txt`. Make sure this directory exists or modify [main.py](main.py#L15) to use a different path.
|
|
|
|
## How It Works
|
|
|
|
1. The bot fetches the RSS feed at regular intervals (defined by `CHECK_INTERVAL`)
|
|
2. For each feed item, it checks if the item's URL has been processed before
|
|
3. If the item is new, it posts to Mastodon with the format: `{title}\n\n{link}`
|
|
4. The item URL is saved to prevent duplicate posts
|
|
5. The process repeats indefinitely
|
|
|
|
## Architecture
|
|
|
|
- **Base Image:** Alpine Linux 3.18 (minimal footprint)
|
|
- **Python Version:** 3.10+
|
|
- **Platforms:** linux/amd64, linux/arm64
|
|
- **Dependencies:** feedparser, mastodon.py (see [requirements.txt](requirements.txt))
|
|
|
|
## State Persistence
|
|
|
|
The bot maintains state in `/state/processed_entries.txt` to track which feed items have already been posted. This prevents duplicate posts across restarts.
|
|
|
|
**Important:** Always mount `/state` as a volume to preserve this state file.
|
|
|
|
## CI/CD
|
|
|
|
The project uses GitHub Actions for automated multiarch builds and deployments:
|
|
|
|
- Builds on every push to `main`
|
|
- Creates images for both amd64 and arm64 architectures
|
|
- Automatically pushes to Docker Hub and GitHub Container Registry
|
|
- Uses Docker layer caching for faster builds
|
|
|
|
See [.github/workflows/masto-rss.yml](.github/workflows/masto-rss.yml) for the full pipeline.
