Setup RabbitMQ

Locally

You can run a RabbitMQ server locally using Docker:

docker run -d --hostname my-rabbit --name some-rabbit rabbitmq:3

You can then interact with the server using the client port: localhost:5672.

Kubernetes

The easiest way to install RabbitMQ on Kubernetes is by using the Helm chart:

helm install rabbitmq stable/rabbitmq

Look at the chart output and get the username and password.

This will install RabbitMQ into the default namespace. To interact with RabbitMQ, find the service with: kubectl get svc rabbitmq.

For example, if installing using the example above, the RabbitMQ server client address would be:

rabbitmq.default.svc.cluster.local:5672

Create a Dapr component

The next step is to create a Dapr component for RabbitMQ.

Create the following YAML file named rabbitmq.yaml:

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: <NAME>
  namespace: <NAMESPACE>
spec:
  type: pubsub.rabbitmq
  metadata:
  - name: host
    value: <REPLACE-WITH-HOST> # Required. Example: "amqp://rabbitmq.default.svc.cluster.local:5672", "amqp://localhost:5672"
  - name: consumerID
    value: <REPLACE-WITH-CONSUMER-ID> # Required. Any unique ID. Example: "myConsumerID"
  - name: durable
    value: <REPLACE-WITH-DURABLE> # Optional. Default: "false"
  - name: deletedWhenUnused
    value: <REPLACE-WITH-DELETE-WHEN-UNUSED> # Optional. Default: "false"
  - name: autoAck
    value: <REPLACE-WITH-AUTO-ACK> # Optional. Default: "false"
  - name: deliveryMode
    value: <REPLACE-WITH-DELIVERY-MODE> # Optional. Default: "0". Values between 0 - 2.
  - name: requeueInFailure
    value: <REPLACE-WITH-REQUEUE-IN-FAILURE> # Optional. Default: "false".

The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described here

Apply the configuration

In Kubernetes

To apply the RabbitMQ pub/sub to Kubernetes, use the kubectl CLI:

kubectl apply -f rabbitmq.yaml

Running locally

To run locally, create a components dir containing the YAML file and provide the path to the dapr run command with the flag --components-path.
