Containers

Question:

In the context of Dapr, what is the purpose of a Dapr sidecar and how does it interact with a container app?

The Dapr sidecar is used to provide a user interface for managing the container app and can be accessed via a web browser.
The Dapr sidecar is used to manage the lifecycle of the container app and has no direct interaction with the app itself.
The Dapr sidecar is used to store the state of the container app and periodically syncs this state with the app.
The Dapr sidecar is used to expose Dapr APIs to the container app, which can be invoked via HTTP or gRPC.

Answer:

A Dapr sidecar exposes Dapr's APIs to your application, enabling features like service invocation and state management over HTTP or gRPC.
While Dapr does provide state management capabilities, it's not the sidecar's responsibility to store the state of the container app and periodically sync it.
