Top-level

Key Required Description Example
name y The name of your resource. mongo
location y The location of your resource. See common values for more information. global
properties y Properties of the resource. See below

Properties

Key Required Description Example
application n The ID of the application resource this resource belongs to. app.id
environment y The ID of the environment resource this resource belongs to. env.id
resourceProvisioning n Specifies how the underlying service/resource is provisioned and managed. Options are to provision automatically via ‘recipe’ or provision manually via ‘manual’. Selection determines which set of fields to additionally require. Defaults to ‘recipe’. manual
host n The hostname of the RabbitMQ instance. rabbitmq.hello.com
port n The port of the RabbitMQ instance. Defaults to 5672. 5672
vHost n The RabbitMQ virtual host (vHost) the client will connect to. Defaults to no vHost. vHost
tls n Specifies whether to use SSL when connecting to the RabbitMQ instance. tls
username n Username to use when connecting to the target rabbitMQ. 'myusername'
recipe n Configuration for the Recipe which will deploy the backing infrastructure. See below
resources n An array of IDs of the underlying resources. See below
queue y The name of the queue. 'orders'
secrets y Configuration used to manually specify a RabbitMQ container or other service providing a RabbitMQ Queue. See secrets below.

Recipe

Property Required Description Example(s)
name n Specifies the name of the Recipe that should be deployed. If not set, the name defaults to default. name: 'azure-prod'
parameters n An object that contains a list of parameters to set on the Recipe. { port: '10040' }

Resources

Property Required Description Example(s)
id n Resource ID of the supporting resource. queue.id

Secrets

Secrets are used when defining a RabbitMQ resource with a container or external service.

Property Description Example
uri The URI to the Rabbit MQ Message Queue. Write only 'amqp://${username}:${password}@${rmqContainer.properties.hostname}:${rmqContainer.properties.port}'
password The password used to connect to this RabbitMQ. Write only. 'mypassword'

Methods

Property Description Example
uri() Returns the RabbitMQ uri used to connect to the resource. amqp://guest:***@rabbitmq.svc.local.cluster:5672

Resource provisioning

Provision with a Recipe

Recipes automate infrastructure provisioning using approved templates. When no Recipe configuration is set Radius will use the Recipe registered as the default in the environment for the given resource. Otherwise, a Recipe name and parameters can optionally be set.

Provision manually

If you want to manually manage your infrastructure provisioning outside of Recipes, you can set resourceProvisioning to 'manual' and provide all necessary parameters and values and values that enable Radius to deploy or connect to the desired infrastructure.

Environment variables for connections

Other Radius resources, such as containers, may connect to a RabbitMQ resource via connections. When a connection to RabbitMQ named, for example, myconnection is declared, Radius injects values into environment variables that are then used to access the connected RabbitMQ resource:

Environment variable Example(s)
CONNECTION_MYCONNECTION_QUEUE 'orders'
CONNECTION_MYCONNECTION_HOST 'rabbitmq.svc.local.cluster'
CONNECTION_MYCONNECTION_PORT '5672'
CONNECTION_MYCONNECTION_VHOST 'qa1'
CONNECTION_MYCONNECTION_USERNAME 'guest'
CONNECTION_MYCONNECTION_TLS 'true'
CONNECTION_MYCONNECTION_URI 'amqp://${username}:${password}@${rmqContainer.properties.hostname}:${rmqContainer.properties.port}'
CONNECTION_MYCONNECTION_PASSWORD 'password'
