Beer Garden in 5 minutes

This guide is designed to get you up and running in Beer Garden in the fastest possible way. We will cover, installing Beer Garden and writing your first plugin. Let’s dive in!


To follow along with this guide, we assume you have the following working:

  • Docker - Installation instructions can be found at Docker Docs

  • Docker Compose - Installation instructions can be found at Docker Docs

  • Git and an account on GitHub

Install Beer Garden

We are going to use docker and docker-compose to install and run Beer Garden.

The first step is to clone the git repository that contains the docker-compose.yml file:

git clone [email protected]:beer-garden/beer-garden.git
cd beer-garden/docker/docker-compose

Beer Garden needs to inform remote plugins the hostname of the RabbitMQ instance that they should connect to for message. This value is set as the BG_AMQ_PUBLISH_HOST in the environment or amq_publish_host in config/command-line arguments. By default in the docker-compose.yml it will be rabbitmq. This will work for containers running on the same network, but if a truly remote plugin exists, you may need to change the value to a resolvable hostname or IP address on the network.

Make sure to use a real IP address and not 'localhost' or ''.
You can also use a fully-qualified domain name instead of an IP address.

Run this command to start beer-garden:

docker-compose up -d

This will create the necessary docker containers and then run them in the background. Run the following command to see the log output from the containers starting:

docker-compose logs -f

Look for a line that says "Bartender started" - once you see that beer-garden is up and running. Use ctrl-c to exit.

beer-garden starts by default on port 2337, so point a browser at http://<IP-ADDRESS>:2337 (where <IP-ADDRESS> is the address you used for the previous step). You’ll see a message saying beer-garden couldn’t find any systems. Don’t worry - you’re about to add one.

Create your first plugin

Now that Beer Garden is up, let’s create a plugin that let’s us use Beer Garden! We will create a simple client that will print and return the message passed to it. Change to your workspace and let’s start coding!

mkdir -p $HOME/my_plugin
cd $HOME/my_plugin

Copy and paste the following code in a file called
from brewtils.decorators import system, parameter
from brewtils.plugin import RemotePlugin

class MyClient(object):

    @parameter(key="message", type="String")
    def do_something(self, message):
        return message

if __name__ == "__main__":
    client = MyClient()
    plugin = RemotePlugin(client, name="my-plugin",
                          bg_port=2337, ssl_enabled=False)
If you are not going to run this plugin inside docker, you might need to change bg_host='brew-view' to your FQDN or IP address on which Beer Garden is running.

Now you can simply run your plugin using one of the images we provide!

docker run -v $(pwd):/src --network dockercompose_bg-network \

Your plugin is now accessible in the Beer Garden GUI! Click on the my-plugin system, and try out the do_something command! Fill out whatever message you want and you should see it in the GUI as well as the output from your docker run command!

This is just the tip of the iceberg, please feel free to look around the site for more information! Happy brewing!
