Workers
Workers operate outside of the Taskcluster services, claiming tasks from the queue and executing them.
Taskcluster currently provides two worker implementations. Docker-worker runs tasks in Docker, and is written in JS. Generic-worker runs on several platforms, with several engines, and is written in Go.

Docker image with generic worker
In order to simplify generic-worker installation, it is possible to build and use docker image to run generic-worker:
cd workers
docker build -t generic-worker:latest .
docker run --rm -it -v /path/to/config.json:/etc/generic-worker/config.json generic-worker:latest
This builds generic-worker for a given architecture, installs needed binaries, generates ed25519 key. On start shows sample config, if it wasn't mounted.
Minimal config.json looks like this:
{
"accessToken": "--access-token--",
"clientId": "--client-id--",
"ed25519SigningKeyLocation": "/etc/generic-worker/ed25519_key",
"rootURL": "https://tc-root.url/",
"workerId": "worker-id",
"workerType": "worker-type",
"livelogExecutable": "/usr/local/bin/livelog",
"taskclusterProxyExecutable": "/usr/local/bin/taskcluster-proxy",
"publicIP": "127.1.2.3"
}
Access Token and Client Id can be created in https://tc-root.url/auth/clients/create.
This image is also used in a local docker compose development environment.
