- This is a personal project that im open-sourcing. Its one of those projects-that-should-exist-but-nobody-wants-to-kill-their-business.
It takes ur standard docker compose file and runs it transparently in kubernetes (k3s actually). So ur devs don't have cognitive dissonance between testing ur stack locally on ur laptop and making it work on kubernetes in production.
It is primarily meant as a dev tool on ur laptop, and as a replacement for docker compose.
- Could I use this for running the same docker compose stack multiple times in parallel? I wrote a lot of bash glue code to make this happen (without kubernetes) for integration and acceptance testing on a single server. Managing envs and networking was a pain, but mostly, I struggle to keep it up to date with infrastructure changes in my platform.

- I've just moved on from docker compose. Instead I have a K8s like yaml file and use podman kube play. The learning curve is pretty small in my opinion and at least it is a little closer to production.
- Just like KIND runs containerd inside docker, you can also run dockerd inside containerd backed pods.
Start a privileged pod with the dind image, copy or mount your compose.yaml inside and you should be able to docker compose up and down, all without mounting a socket (that won't exist anyway on containerd CRI nodes)
To go even further, kubevirt runs on kind, launch a VM with your compose file passed in via cloud-init.

- I'm not quite sure what level of testing this facilitates. If you're testing as close to production as possible, you probably want templated k8s config that scales down to a k8s in CI (e.g. Helm with variables applied that make it minimal). If you just want a local stack to test components and not the k8s config, why not just use docker compose itself?
- Looks promising and really interesting to see and it's a very good idea. But when I saw the test folder however, it is completely empty. [0]
So is any of this tested?

- @sandGorgon8, thank you.
I was just telling some ex coworker friends that there was a great need for a compose frontend to more powerful infra backends, and this feels like the answer.
Once I get working on it I’ll try to add health check support. That is crucial for a lot of what we’re working on.
- So this uses k3s underneath. IMO any local kubernetes distribution is a big resource hog over plain docker. Anyone have ideas for something that is less resource intensive but easier to orchestrate than docker-compose?
