Can I generate Dockerfile for a project when publishing as docker-compose?

[branets-dasha]

I am trying out the docker-compose publish.

I have this in my host project:

builder.AddDockerComposeEnvironment("dc-env");

I have a couple of Web API projects in my solution and have their dependencies configured (databases, message broker, etc).

Running aspire publish I get the docker-compose.yaml, and the images for my API projects are built. The docker-compose references the built images:

  cart-api:
    image: "${CART_API_IMAGE}"

Rather than building the projects' images, is there a way to generate Dockerfiles for them and reference them in docker-compose?

Not really but:

1. We do not emit docker compose files that build images , the assumption id that the source is not available.
2. You can use PublishAsDockerComposeService to or ConfigureComposeFile (https://learn.microsoft.com/en-us/dotnet/aspire/whats-new/dotnet-aspire-9.3#-docker-compose-enhancements). You get full control to tweak the underlying model .
3. There’s nothing that generates a docker file from a project.
