# AodeRelay _A simple and efficient activitypub relay_ ### Usage To simply run the server, the command is as follows ```bash $ ./relay ``` To learn about any other tasks, the `--help` flag can be passed ```bash $ ./relay --help relay 0.2.0 An activitypub relay USAGE: relay [FLAGS] [OPTIONS] FLAGS: -h, --help Prints help information -u, --undo Undo allowing or blocking domains -V, --version Prints version information OPTIONS: -a ... A list of domains that should be allowed -b ... A list of domains that should be blocked ``` 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 ``` Allowed domains are only checked against incoming activities if `RESTRICTED_MODE` is enabled. Blocks can be published in the nodeinfo metadata by setting `PUBLISH_BLOCKS` to true For advanced setups, it may be useful to run the relay API and the background tasks in separate processes, possibly on separate hosts. The `-j` and `-n` flags have been provided for this purpose. By passing `-n`, a relay can be spawned that handles no deliveries. By passing `-j`, a relay will not be spawned, but any deliveries existing in the database will be processed. ### 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 Note that this activity will likely be rejected by the listening servers unless it has been signed with a JSON-LD signature ### Supported Discovery Protocols - Webfinger - NodeInfo ### 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 DATABASE_URL= PRETTY_LOG=true PUBLISH_BLOCKS=false MAX_CONNECTIONS=4 # how many postgres connections should be made ``` 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 DATABASE_URL=postgres://pg_user:pg_pass@pg_host:pg_port/pg_database PRETTY_LOG=false PUBLISH_BLOCKS=true MAX_CONNECTIONS=16 ``` ### Contributing Unless otherwise stated, all contributions to this project will be licensed under the CSL with the exceptions listed in the License section of this file. ### License This work is licensed under the Cooperative Software License.
