Solace-AMQP

Detailed documentation on the Solace-AMQP pubsub component

Component format

To set up Solace-AMQP pub/sub, create a component of type pubsub.solace.amqp. See the pub/sub broker component file to learn how ConsumerID is automatically generated. Read the How-to: Publish and Subscribe guide on how to create and apply a pub/sub configuration.

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: solace
spec:
  type: pubsub.solace.amqp
  version: v1
  metadata:
    - name: url
      value: 'amqp://localhost:5672'
    - name: username
      value: 'default'
    - name: password
      value: 'default'
    - name: consumerID
      value: 'channel1'

Spec metadata fields

Field Required Details Example
url Y Address of the AMQP broker. Can be secretKeyRef to use a secret reference.
Use the amqp:// URI scheme for non-TLS communication.
Use the amqps:// URI scheme for TLS communication.		 "amqp://host.domain[:port]"
username Y The username to connect to the broker. Only required if anonymous is not specified or set to false . default
password Y The password to connect to the broker. Only required if anonymous is not specified or set to false. default
consumerID N Consumer ID (consumer tag) organizes one or more consumers into a group. Consumers with the same consumer ID work as one virtual consumer; for example, a message is processed only once by one of the consumers in the group. If the consumerID is not provided, the Dapr runtime set it to the Dapr application ID (appID) value. "channel1"
anonymous N To connect to the broker without credential validation. Only works if enabled on the broker. A username and password would not be required if this is set to true. true
caCert Required for using TLS Certificate Authority (CA) certificate in PEM format for verifying server TLS certificates. "-----BEGIN CERTIFICATE-----\n<base64-encoded DER>\n-----END CERTIFICATE-----"
clientCert Required for using TLS TLS client certificate in PEM format. Must be used with clientKey. "-----BEGIN CERTIFICATE-----\n<base64-encoded DER>\n-----END CERTIFICATE-----"
clientKey Required for using TLS TLS client key in PEM format. Must be used with clientCert. Can be secretKeyRef to use a secret reference. "-----BEGIN RSA PRIVATE KEY-----\n<base64-encoded PKCS8>\n-----END RSA PRIVATE KEY-----"

Communication using TLS

To configure communication using TLS:

  1. Ensure that the Solace broker is configured to support certificates.
  2. Provide the caCert, clientCert, and clientKey metadata in the component configuration.

For example:

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: solace
spec:
  type: pubsub.solace.amqp
  version: v1
  metadata:
  - name: url
    value: "amqps://host.domain[:port]"
  - name: username
    value: 'default'
  - name: password
    value: 'default'
  - name: caCert
    value: ${{ myLoadedCACert }}
  - name: clientCert
    value: ${{ myLoadedClientCert }}
  - name: clientKey
    secretKeyRef:
      name: mySolaceClientKey
      key: mySolaceClientKey
auth:
  secretStore: <SECRET_STORE_NAME>

While the caCert and clientCert values may not be secrets, they can be referenced from a Dapr secret store as well for convenience.

Publishing/subscribing to topics and queues

By default, messages are published and subscribed over topics. If you would like your destination to be a queue, prefix the topic with queue: and the Solace AMQP component will connect to a queue.

Create a Solace broker


You can run a Solace broker locally using Docker:

docker run -d -p 8080:8080 -p 55554:55555 -p 8008:8008 -p 1883:1883 -p 8000:8000 -p 5672:5672 -p 9000:9000 -p 2222:2222 --shm-size=2g --env username_admin_globalaccesslevel=admin --env username_admin_password=admin --name=solace solace/solace-pubsub-standard

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


You can also sign up for a free SaaS broker on Solace Cloud.
