ATproto labeler

This is an implementation of a basic labeler. It does not have any UI and does not impose any workflow on you. Labels can be created via an API, or any other way you implement.

Getting started

1. Clone this repository.
2. Copy example.env to .env and at the very least uncomment and edit DATA_DIR variable there.
3. Copy example_config.yaml to config.yaml. Generate and put there a private key. Edit or simply remove everything after the line with the private key.
4. Run docker compose up --build -d

Congratulations! You've got yourself a perfectly useless labeler :) (by default there's no way to create any labels)

Enabling a simple API

Copy docker-compose.override.example.yaml to docker-compose.override.yaml and run docker compose up -d.

Now you can create labels by sending them as a POST request to http://127.0.0.1:8081/label, e.g.:

curl -X POST --json '{"uri": "did:plc:foobar","val": "!hide"}' http://127.0.0.1:8081/label

Note that there's no authentication whatsoever, so you should not expose this port to outside world. This API is intended only as an example. If you insist on using it anyway - at least put it behind a reverse proxy with authentication.

Setting up the labeler account to actually work

For someone to be able to subscribe to your labeler and see the labels, two things need to happen:

1. Labeler service record need to exist in the PDS.
2. DID document needs to have labeler's signing key and service endpoint.

Updating PLC

1. Ensure that you have did, password, private_key and endpoint set in your config.
2. While your labeler is running, run docker compose exec labeler ./update-plc --config=/config.yaml.
3. If any changes are needed, you will see a message stating that. Wait for the email with the token and re-run the same command, but add --token flag

Updating labeler service record

labeler and list-labeler automatically do it at startup. Just make sure that in your config you have labels set up the way you want them, and that did and password are specified too.

Migrating from Ozone

WARNING: this wasn't tested yet on any live instance, please report any issues if you do this.

cmd/clone implements making a copy of a labeler with the same sequence numbers, so cursor values any consumers have will remain valid and point to the same data.

1. Keep Ozone running, but ensure that no new changes are happening.
2. docker compose run --entrypoint=./clone labeler --config=/config.yaml --from=https://your.ozone.instance
3. If it completes without errors, start your labeler with docker compose up -d

Labeling accounts based on a mute list

There's an implementation of a labeler that takes a list and converts it into a label in cmd/list-labeler directory.

1. Add lists entry to your config file. It should be a mapping from label name to a list URI.
2. Copy docker-compose.override.example.yaml to docker-compose.override.yaml, if you haven't yet.
3. Uncomment entrypoint line and comment out admin API from both ports and command sections.
4. Ensure that you have did and password set in your config file.
5. Run docker compose up -d.

One caveat is that it uses app.bsky.graph.getList call to fetch the list members. Due to that, if someone blocks your account - they won't be returned in the response and list-labeler would think that they have been removed from the list.

Further customization

You can use cmd/labeler as a starting point for implementing your own labeler. You don't necessarily even need to fork this repo. Just copy cmd/labeler/main.go and import bsky.watch/labeler module.
