Error message

no service image

What it means

ErrNoServiceImage is defined in pkg/app/master/compose/execution.go and signals that a compose service has no image to work with — the service definition lacks an image and no built image is available, so the compose execution cannot proceed for that service.

Solutions

1. Add an `image:` field to the service in the compose file
2. Build the image first (docker compose build) so a local image exists before running the tool
3. Verify you targeted the correct service name in the compose project

Example fix

# before
services:
  app:
    build: ./app
# after
services:
  app:
    build: ./app
    image: myapp:latest

svc := project.Services["app"]
if svc.Image == "" {
	return fmt.Errorf("service %q has no image; add an image: field or build first", "app")
}

When it happens

Trigger: Running the compose execution/minification flow against a compose file whose service omits the `image` key and relies solely on a `build` section without a pre-built image present.

Common situations: Compose files that only specify build:; services expected to be built by an earlier step that was never run; typos in the service name in the compose file.
