Dapr .NET SDK Development with Docker-Compose
Consider this to be a .NET companion to the Dapr Self-Hosted with Docker Guide.
docker-compose is a CLI tool included with Docker Desktop that you can use to run multiple containers at a time. It is a way to automate the lifecycle of multiple containers together, and offers a development experience similar to a production environment for applications targeting Kubernetes.
- Pro: Since
docker-composemanages containers for you, you can make dependencies part of the application definition and stop the long-running containers on your machine.
- Con: most investment required, services need to be containerized to get started.
- Con: can be difficult to debug and troubleshoot if you are unfamilar with Docker.
From the .NET perspective, there is no specialized guidance needed for
docker-compose with Dapr.
docker-compose runs containers, and once your service is in a container, configuring it similar to any other programming technology.
💡 App PortIn a container, an ASP.NET Core app will listen on port 80 by default. Remember this for when you need to configure the
To summarize the approach:
- Create a
Dockerfilefor each service
- Create a
docker-compose.yamland place check it in to the source code repository
To understand the authoring the
docker-compose.yaml you should start with the Hello, docker-compose sample.
Similar to running locally with
dapr run for each service you need to choose a unique app-id. Choosing the container name as the app-id will make this simple to remember.
The compose file will contain at a minimum:
- A network that the containers use to communicate
- Each service’s container
<service>-daprdsidecar container with the service’s port and app-id specified
- Additional dependencies that run in containers (redis for example)
- optional: Dapr placement container (for actors)
You can also view a larger example from the eShopOnContainers sample application.
