|
||||
## Setup
|
||||
|
||||
You need at least Python 3.6 (latest version of 3.x recommended) to make use of this software.
|
||||
It simply will not run on older Python versions.
|
||||
|
||||
Download the project and install with pip (`pip3 install .`).
|
||||
|
||||
Copy `relay.yaml.example` to `relay.yaml` and edit it as appropriate:
|
||||
|
||||
$ cp relay.yaml.example relay.yaml
|
||||
$ $EDITOR relay.yaml
|
||||
|
||||
Finally, you can launch the relay:
|
||||
|
||||
$ python3 -m relay
|
||||
|
||||
It is suggested to run this under some sort of supervisor, such as runit, daemontools,
|
||||
s6 or systemd. Configuration of the supervisor is not covered here, as it is different
|
||||
depending on which system you have available.
|
||||
|
||||
The bot runs a webserver, internally, on localhost at port 8080. This needs to be
|
||||
forwarded by nginx or similar. The webserver is used to receive ActivityPub messages,
|
||||
and needs to be secured with an SSL certificate inside nginx or similar. Configuration
|
||||
of your webserver is not discussed here, but any guide explaining how to configure a
|
||||
modern non-PHP web application should cover it.
|
||||
|
||||
|
||||
## Getting Started
|
||||
|
||||
Normally, you would direct your LitePub instance software to follow the LitePub actor

|
@ -44,38 +17,7 @@ found on the relay. In Pleroma this would be something like:
|
|||
|
||||
$ MIX_ENV=prod mix relay_follow https://your.relay.hostname/actor
|
||||
|
||||
Mastodon uses an entirely different relay protocol but supports LitePub relay protocol
|
||||
as well when the Mastodon relay handshake is used. In these cases, Mastodon relay
|
||||
clients should follow `http://your.relay.hostname/inbox` as they would with Mastodon's
|
||||
own relay software.
|
||||
|
||||
## Documentation
|
||||
|
||||
## Performance
|
||||
|
||||
Performance is very good, with all data being stored in memory and serialized to a
|
||||
JSON-LD object graph. Worker coroutines are spawned in the background to distribute
|
||||
the messages in a scatter-gather pattern. Performance is comparable to, if not
|
||||
superior to, the Mastodon relay software, with improved memory efficiency.
|
||||
|
||||
|
||||
## Management
|
||||
|
||||
You can perform a few management tasks such as peering or depeering other relays by
|
||||
invoking the `relay.manage` module.
|
||||
|
||||
This will show the available management tasks:
|
||||
|
||||
$ python3 -m relay.manage
|
||||
|
||||
When following remote relays, you should use the `/actor` endpoint as you would in
|
||||
Pleroma and other LitePub-compliant software.
|
||||
|
||||
## Docker
|
||||
|
||||
You can run ActivityRelay with docker. Edit `relay.yaml` so that the database
|
||||
location is set to `./data/relay.jsonld` and then build and run the docker
|
||||
image :
|
||||
|
||||
$ docker volume create activityrelay-data
|
||||
$ docker build -t activityrelay .
|
||||
$ docker run -d -p 8080:8080 -v activityrelay-data:/workdir/data activityrelay
|
||||

# Commands
|
||||
|
||||
There are a number of commands to manage your relay's database and config. You can add `--help` to
|
||||
any category or command to get help on that specific option (ex. `activityrelay inbox --help`).
|
||||
|
||||
Note: Unless specified, it is recommended to run any commands while the relay is shutdown.

|
||||
|
||||
|
||||
### Add
|
||||
|
||||
Add an inbox to the database. If a domain is specified, it will default to `https://{domain}/inbox`.
|
||||
If the added instance is not following the relay, expect errors when pushing messages.

# Configuration
|
||||
|
||||
## DB
|
||||
|
||||
The path to the database. It contains the relay actor private key and all subscribed
|
||||
instances. If the path is not absolute, it is relative to the working directory.
|
||||
|
||||
db: relay.jsonld
|
||||
|
||||
|
||||
## Listener
|
||||
|
||||
The address and port the relay will listen on. If the reverse proxy (nginx, apache, caddy, etc)
|
||||
is running on the same host, it is recommended to change `listen` to `localhost`
|
||||
|
||||
listen: 0.0.0.0
|
||||
port: 8080
|
||||
|
||||
|
||||
## Note
|
||||
|
||||
A small blurb to describe your relay instance. This will show up on the relay's home page.
|
||||
|
||||
note: "Make a note about your instance here."
|
||||
|
||||
|
||||
## Post Limit
|
||||
|
||||
The maximum number of messages to send out at once. For each incoming message, a message will be
|
||||
sent out to every subscribed instance minus the instance which sent the message. This limit
|
||||
is to prevent too many outgoing connections from being made, so adjust if necessary.
|
||||
|
||||
push_limit: 512
|
||||
|
||||
|
||||
## AP
|
||||
|
||||
Various ActivityPub-related settings
|
||||
|
||||
|
||||
### Host
|
||||
|
||||
The domain your relay will use to identify itself.
|
||||
|
||||
host: relay.example.com
|
||||
|
||||
|
||||
### Whitelist Enabled
|
||||
|
||||
If set to `true`, only instances in the whitelist can follow the relay. Any subscribed instances
|
||||
not in the whitelist will be removed from the inbox list on startup.
|
||||
|
||||
whitelist_enabled: false
|
||||
|
||||
|
||||
### Whitelist
|
||||
|
||||
A list of domains of instances which are allowed to subscribe to your relay.
|
||||
|
||||
whitelist:
|
||||
- bad-instance.example.com
|
||||
- another-bad-instance.example.com
|
||||
|
||||
|
||||
### Blocked Instances
|
||||
|
||||
A list of instances which are unable to follow the instance. If a subscribed instance is added to
|
||||
the block list, it will be removed from the inbox list on startup.
|
||||
|
||||
blocked_instances:
|
||||
- bad-instance.example.com
|
||||
- another-bad-instance.example.com
|
||||
|
||||
|
||||
### Blocked Software
|
||||
|
||||
A list of ActivityPub software which cannot follow your relay. This list is empty by default, but
|
||||
setting this to the above list will block all other relays and prevent relay chains
|
||||
|
||||
blocked_software:
|
||||
- activityrelay

||||
|
||||
These are object limits for various caches. Only change if you know what you're doing.
|
||||
|
||||
|
||||
### Objects
|
||||
|
||||
The urls of messages which have been processed by the relay.
|
||||
|
||||
objects: 1024
|
||||
|
||||
|
||||

# Installation
|
||||
|
||||
There are a few ways to install ActivityRelay. Follow one of the methods below, setup a reverse
|
||||
proxy, and setup the relay to run via a supervisor. Example configs for caddy, nginx, and systemd
|
||||
in `installation/`
|
||||
|
||||
|
||||
## Pipx
|
||||
|
||||
Pipx uses pip and a custom venv implementation to automatically install modules into a Python
|
||||
environment and is the recommended method. Install pipx if it isn't installed already. Check out
|
||||
the [official pipx docs](https://pypa.github.io/pipx/installation/) for more in-depth instructions.
|
||||
|
||||
python3 -m pip install pipx
|
||||
|
||||
Now simply install ActivityRelay directly from git
|
||||
|
||||
pipx install git+https://git.pleroma.social/pleroma/relay@0.2.0
|
||||
|
||||
Or from a cloned git repo.
|
||||
|
||||
pipx install .
|
||||
|
||||
Once finished, you can set up the relay via the setup command. It will ask a few questions to fill
|
||||
out config options for your relay
|
||||
|
||||
activityrelay setup
|
||||
|
||||
Finally start it up with the run command.
|
||||
|
||||
activityrelay run
|
||||
|
||||
Note: Pipx requires python 3.7+. If your distro doesn't have a compatible version of python, it can
|
||||
be installed via
|
||||
|
||||
|
||||
## Pip
|
||||
|
||||
The instructions for installation via pip are very similar to pipx. Installation can be done from
|
||||
git
|
||||
|
||||
python3 -m pip install git+https://git.pleroma.social/pleroma/relay@0.2.0
|
||||
|
||||
or a cloned git repo.
|
||||
|
||||
python3 -m pip install .
|
||||
|
||||
Now run the configuration wizard
|
||||
|
||||
activityrelay setup
|
||||
|
||||
And start the relay when finished
|
||||
|
||||
activityrelay run
|
||||
|
||||
|
||||
## Docker
|
||||
|
||||
Installation and management via Docker can be handled with the `docker.sh` script. To install
|
||||
ActivityRelay, run the install command. Once the image is built and the container is created,
|
||||
your will be asked to fill out some config options for your relay.
|
||||
|
||||
./docker.sh install
|
||||
|
||||
Finally start it up. It will be listening on TCP port 8080.
