Configuration

General

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.

Note: If the workers option is set to anything above 0, this limit will be per worker.

push_limit: 512

Push Workers

The relay can be configured to use threads to push messages out. For smaller relays, this isn't necessary, but bigger ones (>100 instances) will want to set this to the number of available cpu threads.

workers: 0

JSON GET cache limit

JSON objects (actors, nodeinfo, etc) will get cached when fetched. This will set the max number of objects to keep in the cache.

json_cache: 1024

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 below list will block all other relays and prevent relay chains

blocked_software:
- activityrelay
- aoderelay
- social.seattle.wa.us-relay
- unciarelay
