# AodeRelay _A simple and efficient activitypub relay_ ### Installation #### Docker If running docker, you can start the relay with the following command: ``` $ sudo docker run --rm -it \ -v "./:/mnt/" \ -e ADDR=0.0.0.0 \ -e SLED_PATH=/mnt/sled/db-0.34 \ -p 8080:8080 \ asonix/relay:0.3.73 ``` This will launch the relay with the database stored in "./sled/db-0.34" and listening on port 8080 #### Cargo With cargo installed, the relay can be installed to your cargo bin directory with the following command ``` $ cargo install ap-relay ``` Then it can be run with this: ``` $ ADDR=0.0.0.0 relay ``` This will launch the relay with the database stored in "./sled/db-0.34" and listening on port 8080 #### Source The relay can be launched directly from this git repository with the following commands: ``` $ git clone https://git.asonix.dog/asonix/relay $ ADDR=0.0.0.0 cargo run --release ``` ### Usage To simply run the server, the command is as follows ```bash $ ./relay ``` #### Administration > **NOTE:** The server _must be running_ in order to update the lists with the following commands To learn about any other tasks, the `--help` flag can be passed ```bash An activitypub relay Usage: relay [OPTIONS] Options: -b A list of domains that should be blocked -a A list of domains that should be allowed -u, --undo Undo allowing or blocking domains -h, --help Print help information ``` To add domains to the blocklist, use the `-b` flag and pass a list of domains ```bash $ ./relay -b asonix.dog blimps.xyz ``` To remove domains from the blocklist, simply pass the `-u` flag along with `-b` ```bash $ ./relay -ub asonix.dog blimps.xyz ``` The same rules apply for allowing domains, although domains are allowed with the `-a` flag ```bash $ ./relay -a asonix.dog blimps.xyz $ ./relay -ua asonix.dog blimps.xyz ``` ### Configuration By default, all these values are set to development values. These are read from the environment, or from the `.env` file in the working directory. ```env HOSTNAME=localhost:8080 ADDR=127.0.0.1 PORT=8080 DEBUG=true RESTRICTED_MODE=false VALIDATE_SIGNATURES=false HTTPS=false PRETTY_LOG=true PUBLISH_BLOCKS=false SLED_PATH=./sled/db-0.34 ``` To run this server in production, you'll likely want to set most of them ```env HOSTNAME=relay.my.tld ADDR=0.0.0.0 PORT=8080 DEBUG=false RESTRICTED_MODE=false VALIDATE_SIGNATURES=true HTTPS=true PRETTY_LOG=false PUBLISH_BLOCKS=true SLED_PATH=./sled/db-0.34 RUST_LOG=warn API_TOKEN=somepasswordishtoken OPENTELEMETRY_URL=localhost:4317 TELEGRAM_TOKEN=secret TELEGRAM_ADMIN_HANDLE=your_handle TLS_KEY=/path/to/key TLS_CERT=/path/to/cert FOOTER_BLURB="Contact @asonix for inquiries" LOCAL_DOMAINS=masto.asonix.dog LOCAL_BLURB="

Welcome to my cool relay where I have cool relay things happening. I hope you enjoy your stay!

" ``` #### Descriptions ##### `HOSTNAME` The domain or IP address the relay is hosted on. If you launch the relay on `example.com`, that would be your HOSTNAME. The default is `localhost:8080` ##### `ADDR` The address the server binds to. By default, this is `127.0.0.1`, so for production cases it should be set to `0.0.0.0` or another public address. ##### `PORT` The port the server binds to, this is `8080` by default but can be changed if needed. ##### `DEBUG` Whether to print incoming activities to the console when requests hit the /inbox route. This defaults to `true`, but should be set to `false` in production cases. Since every activity sent to the relay is public anyway, this doesn't represent a security risk. ##### `RESTRICTED_MODE` This setting enables an 'allowlist' setup where only servers that have been explicitly enabled through the `relay -a` command can join the relay. This is `false` by default. If `RESTRICTED_MODE` is not enabled, then manually allowing domains with `relay -a` has no effect. ##### `VALIDATE_SIGNATURES` This setting enforces checking HTTP signatures on incoming activities. It defaults to `true` ##### `HTTPS` Whether the current server is running on an HTTPS port or not. This is used for generating URLs to the current running relay. By default it is set to `true` ##### `PUBLISH_BLOCKS` Whether or not to publish a list of blocked domains in the `nodeinfo` metadata for the server. It defaults to `false`. ##### `SLED_PATH` Where to store the on-disk database of connected servers. This defaults to `./sled/db-0.34`. ##### `RUST_LOG` The log level to print. Available levels are `ERROR`, `WARN`, `INFO`, `DEBUG`, and `TRACE`. You can also specify module paths to enable some logs but not others, such as `RUST_LOG=warn,tracing_actix_web=info,relay=info`. This defaults to `warn` ##### `SOURCE_REPO` The URL to the source code for the relay. This defaults to `https://git.asonix.dog/asonix/relay`, but should be changed if you're running a fork hosted elsewhere. ##### `API_TOKEN` The Secret token used to access the admin APIs. This must be set for the commandline to function ##### `OPENTELEMETRY_URL` A URL for exporting opentelemetry spans. This is mostly useful for debugging. There is no default, since most people probably don't run an opentelemetry collector. ##### `TELEGRAM_TOKEN` A Telegram Bot Token for running the relay administration bot. There is no default. ##### `TELEGRAM_ADMIN_HANDLE` The handle of the telegram user allowed to administer the relay. There is no default. ##### `TLS_KEY` Optional - This is specified if you are running the relay directly on the internet and have a TLS key to provide HTTPS for your relay ##### `TLS_CERT` Optional - This is specified if you are running the relay directly on the internet and have a TLS certificate chain to provide HTTPS for your relay ##### `FOOTER_BLURB` Optional - Add custom notes in the footer of the page ##### `LOCAL_DOMAINS` Optional - domains of mastodon servers run by the same admin as the relay ##### `LOCAL_BLURB` Optional - description for the relay ### Subscribing Mastodon admins can subscribe to this relay by adding the `/inbox` route to their relay settings. For example, if the server is `https://relay.my.tld`, the correct URL would be `https://relay.my.tld/inbox`. Pleroma admins can subscribe to this relay by adding the `/actor` route to their relay settings. For example, if the server is `https://relay.my.tld`, the correct URL would be `https://relay.my.tld/actor`. ### Supported Activities - Accept Follow {remote-actor}, this is a no-op - Reject Follow {remote-actor}, an Undo Follow is sent to {remote-actor} - Announce {anything}, {anything} is Announced to listening servers - Create {anything}, {anything} is Announced to listening servers - Follow {self-actor}, become a listener of the relay, a Follow will be sent back - Follow Public, become a listener of the relay - Undo Follow {self-actor}, stop listening on the relay, an Undo Follow will be sent back - Undo Follow Public, stop listening on the relay - Delete {anything}, the Delete {anything} is relayed verbatim to listening servers. Note that this activity will likely be rejected by the listening servers unless it has been signed with a JSON-LD signature - Update {anything}, the Update {anything} is relayed verbatim to listening servers.
