It's hard to copy files into a volume

[carolynvs]

I was trying to use a docker compose file that used this line:

services:
  svcA
    volumes:
    - ./config.yaml:/etc/config.yaml

This doesn't work because the docker host doesn't have access the files in the bundle (we are running DooD).

As a workaround, I am doing this inside the bundle to copy files into a volume, and using the existing volume in docker compose.

    echo "Creating otel-jaeger-config volume"
    docker volume create otel-jaeger-config || true
    
    echo "Copying otel config into volume..."
    docker rm otel-jaeger-helper 2&> /dev/null || true
    docker run -v otel-jaeger-config:/config --name otel-jaeger-helper busybox true
    trap "docker rm otel-jaeger-helper" EXIT

    docker cp config.yaml otel-jaeger-helper:/config

I don't think that this is that far out of a use case. It would be nice if we could figure out a way to easily copy files from the bundle into a volume that can be used later in the bundle.
