If you mean the Docker client, Podman comes to mind. Honestly though, if you don't like Podman, I'd recommend Minikube. Then again, if you know nothing of Kubernetes, I'd stick with Podman (which has limitations on anything but Linux AFAIK). You might create wrappers around runc [1] if you really wanted (wouldn't recommend) or containerd [2] (no personal experience on my part). If you mean the Docker registry, there are a number of alternatives, like quay.io or MCR.
