Arena

An intuitive Web GUI for Bee Queue and Bull. Built on Express so you can run Arena standalone, or mounted in another app as middleware.

For a quick introduction to the motivations for creating Arena, read Interactively monitoring Bull, a Redis-backed job queue for Node.

Usage

Prerequisites

Configure your queues in the "queues" key of index.json. Queues take the following format:

{
  "name": "my_queue",
  "port": 6381,
  "host": "127.0.0.1",
  "hostId": "AWS Server 2"
}

The name, port, host, and hostId fields are required. hostId can be given any name, so it is recommended to give it a helpful name for reference. Optionally, you can also pass in db and password to configure redis credentials, or prefix to specify the customized prefix of the queue.

You can also provide a url field instead of host, port db and password.

To specify a custom file location, see "Running Arena as a node module".

Note that if you happen to use Amazon Web Services' Elasticache as your Redis host, check out http://mixmax.com/blog/bull-queue-aws-autodiscovery

Running the server

Run npm install to fetch Arena's dependencies. Then run npm start to start the server.

Note that because Arena is dependent on async/await, Arena only currently supports Node >7.

Running Arena as a node module

Alternatively, you can use Arena as a node module. This has potential benefits:

Arena can be configured to use any method of server/queue configuration desired
- for example, fetching available redis queues from an AWS instance on server start
- or even just plain old reading from environment variables
Arena can be mounted in other express apps as middleware

Usage:

In project folder:

yarn add bull-arena

In router.js:

const Arena = require('bull-arena');

const express = require('express');
const router = express.Router();

const arena = Arena({queues});
router.use('/', arena);

Arena takes two arguments. The first, config, is a plain object containing the queue configuration. The second, listenOpts, is an object that can contain the following optional parameters:

port - specify custom port to listen on (default: 4567)
basePath - specify custom path to mount server on (default: '/')
disableListen - don't let the server listen (useful when mounting Arena as a sub-app of another Express app) (default: false)

Bee Queue support

Arena is dual-compatible with Bull 3.x and Bee-Queue 1.x. To add a Bee queue to the Arena dashboard, include the type: bee attribute with an individual queue's configation object.

Docker image

You can now docker pull Arena from Docker Hub.

To build the image simply run:

docker build -t <name-image> .

To run a container, execute the following command. Note that we need to settle the location of index.json in this container via volume mounting:

docker run -p 4567:4567 -v </local/route/to/index.json>:/opt/arena/src/server/config/index.json <name-image>

Development

Arena is written using Express, with simple jQuery and Handlebars on the front end.

If updating dependencies, please use Yarn and update the yarn.lock file before submitting a pull request.
