Dapr Pub Sub

In this lab we will explore the use of the publish and subscribe Dapr component. The diagram below illustrates the architecture of the lab.

How complete the lab:

1. Start Dapr using dapr init this will create the Dapr pub/sub component.
2. Start the subscriber dapr run --app-id dapr-pubsub-subscriber --app-port=8081 -- cargo run --manifest-path ./dapr-pubsub-subscriber/Cargo.toml
3. Start the publisher dapr run --app-id dapr-pubsub-publisher -- cargo run --manifest-path ./dapr-pubsub-publisher/Cargo.toml
4. Observe the logs of both applications. You should see every three seconds a message with a timestamp and some meta information.

Done!
