Podman is probably the best competitor to docker currently.   Main issue is it isn't as well known so their aren't as many docs on it. It has a lot of promise though.

K8s is a massive, massive beast, I'd equate it more to a cloud than just a container engine.

Are Docker and K8s really competitors though? Unless you mean Docker Compose? You can run Docker containers in K8s

After realizing that docker is also to blame for my constant network interruptions and the only solution seems to be to disable IPv6 [0], I am also interested in alternatives to docker.

I've seen some people in the docker github mentioning that they switched to [Podman](https://podman.io/). The only other thing that comes into my mind is [K8s](https://kubernetes.io/). But I don't have experience with any of them so not sure how well they suit your use case.
