How would you configure the platform architecture using the PublishAsDockerComposeService extension?

[Clink50]

I'm attempting to dockerize my .NET Aspire application and send it to my raspberry pi to run as a web server. The architecture for the pi is linux/arm64, so I need to configure the platform in the docker compose to build the image correctly, but I'm not seeing an option for "platform" in the Service class.

Hello @Clink50,
Aspire itself doesn’t seem to provide a first-class API for setting the platform per service.
You can try this workaround, using an override raw yml to specify the platform.

services:
  my-service:
    image: myapp:latest
    platform: linux/arm64

Are you trying to build projects or docker files? If projects, you can set the architecture in your csproj using

<ContainerRuntimeIdentifier>linux-arm64</ContainerRuntimeIdentifier>

Thank you @davidfowl, I just saw this in your AspirePipelines repo last night and this worked perfectly.
