Dapr

What is Dapr?

I heard this Distributed Application Runtime (Dapr) concept from Scott Hanselman in his Azure Friday.

Dapr, an open source project that invented by Microsoft and contributed by all of the famous cloud providers, can be used to build event-driven, resilient distributed applications. It can help developers concentrate on implementing business logic without worrying about the cloud provider (e.g. AWS, Azure, GCP or Alibaba) or different SDKs from different cloud providers.

Prerequisites

• Install Dapr CLI
• Install kubectl “Docker Desktop” works fine for me, I will install “minikube” later.

Supported Bindings

https://docs.dapr.io/reference/components-reference/supported-bindings/

Generic

• Twilio SendGrid

Pub Sub

• Redis

Tips

• Make sure those containers are running if Dapr is Self-Hosted
  • openzipkin/zipkin
  • daprio/dapr
  • redis

  Without those containers, “redis” will not be available for state or pubsub. By default, “Dapr Init” will download those images and run them in docker.

• Check Dapr logs in Kubernetes container

  kubectl logs [container-name] daprd
