Settings Installation

Oban Web is delivered as a hex package named oban_web, which is published privately to our self-hosted package repository. The package is entirely self contained—it doesn't hook into your asset pipeline at all.

prerequisites

Prerequisites

1. Ensure Oban is installed for your application. It's probably there already, but just in case, follow these instructions to get started.

2. Ensure Phoenix Live View is installed and working in your application. If you don't have Live View, follow these instructions to get started.

3. Ensure you're running Erlang/OTP v23.3.4.5, v24.0.4, or later. Older Erlang/OTP versions have an expired CA root certificate that doesn't work with Let's Encrypt certificates.

4. Ensure you're running hex v1.0.0 or later, via mix local.hex --force

authentication

Authentication

Before you can pull the package into your application you need to add a new oban hex repo. First, grab the OBAN_KEY_FINGERPRINT and OBAN_LICENSE_KEY from your account page.

Then, run the following mix hex.repo command:

mix hex.repo add oban https://getoban.pro/repo \
  --fetch-public-key $OBAN_KEY_FINGERPRINT \
  --auth-key $OBAN_LICENSE_KEY

⚠️ You'll also need to authenticate on any other development machines, build servers and CI instances. There are also guides to help with building Docker Images, authenticating on Gigalixir, and on Heroku.

configuration

Configuration

Now that you're authenticated you're ready to add oban_web as a dependency for your application. Open mix.exs and add the following line:

{:oban_web, "~> 2.9", repo: "oban"}

Now fetch your dependencies:

$ mix deps.get

This will fetch both oban_web and oban_pro, if you haven't already installed oban_pro.

The Gossip plugin and the Stats plugin are necessary for the dashboard to function properly. Add them to your Oban configuration in config.exs:

config :my_app, Oban,
  repo: MyApp.Repo,
  queues: [alpha: 10, gamma: 10, delta: 10],
  plugins: [
    Oban.Plugins.Gossip,
    Oban.Web.Plugins.Stats
  ]

After configuration you can mount the dashboard within your application's router.ex:

# lib/my_app_web/router.ex
use MyAppWeb, :router

import Oban.Web.Router

...

scope "/" do
  pipe_through :browser

  oban_dashboard "/oban"
end

Here we're using "/oban" as the mount point, but it can be anywhere you like. After you've verified that the dashboard is loading you'll probably want to restrict access to the dashboard via authentication, e.g. with Basic Auth.

Installation is complete and you're all set! Start your Phoenix server, point your browser to where you mounted Oban and start monitoring your jobs.
