I love docker-compose and have used it every day. There are a bunch of
workflows I use compose for that I haven't figured out how to replace
with Guix yet, and I'm not in a huge hurry, but it would be great to see
features that are designed to appeal to Compose users.

For example, a common thing I do with docker-compose is to provide a
compose file with a service I'm working on that brings up the service
with all its dependencies (eg databases,  proxies, etc.) in a dev
configuration, with the source code from the repository mapped into the
container and live-reload enabled. That creates a "two-step" dev
environment for the service: you clone the repo then run "docker-compose
up."

Hashicorp has been working on Waypoint[1], a free software tool to
extend that concept even further by adding deployment and release
capabilities. Now you clone a repo and you have one tool to build,
deploy and release the software contained therein.

I'm interested to use Guix for similar purposes, but there are a few
primary obstacles in the way:
1) I don't have enough experience yet defining systems using Guix
similar to what I'd define using docker-compose, and I haven't found
documentation or examples yet that makes it seem within reach
2) The machines I'm deploying to run Kubernetes, not Guix System, so if
I do use Guix to build a bundle for deployment its utility ends when I
export to a Docker container image.
3) I collaborate with developers who use macOS and Windows and so can't
easily install and use Guix.
