wireguard-go-docker VS slirp4netns

I thought wireguard-go requires the kernel tun device. See for example this Docker image for wireguard-go which maps the tun device and requires elevated permissions - https://github.com/masipcat/wireguard-go-docker

I was just curious if it's just me. It seems theres a few posts on various places on the internet on this and the questions are not answered on any of them (EG: https://github.com/masipcat/wireguard-go-docker/issues/19)

History likes to repeat itself:

https://github.com/rootless-containers/slirp4netns

It should not actually require root anymore - see https://github.com/rootless-containers/slirp4netns

USER root RUN curl -o /var/lib/apt/dazzle-marks/docker.gpg -fsSL https://download.docker.com/linux/ubuntu/gpg \ && apt-key add /var/lib/apt/dazzle-marks/docker.gpg \ && add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" \ && install-packages docker-ce docker-ce-cli containerd.io RUN curl -o /usr/bin/slirp4netns -fsSL https://github.com/rootless-containers/slirp4netns/releases/download/v1.1.12/slirp4netns-$(uname -m) \ && chmod +x /usr/bin/slirp4netns

Podman pods are kind of their own thing, networking wise, being under slirp4netns https://github.com/rootless-containers/slirp4netns

i foud this slirp4netns in the meantime as well. There are a bunch of other problems. with podman. I cannot use nftables and firewalld with systemd+nftables, the mentioned port-"problem" for rootless podman, ipv6 containers and some other stuff that isn't working or very config-heavy. i found a lot of github issues that are actively discussed in the past days regarding some of the mentioned topics on this post. My conclusion is that i will still use docker and will look into this in a year or so... to early imo to really switch to podman because almost no benefits to docker for me. (i want ipv6, rootless containers all the way and full nftable support)
