What Hacker News says
8 sourcesPodman can also deploy from Kubernetes config https://github.com/containers/podman/blob/master/docs/source...
In Nomad v1.0 release – workload orchestrationCompletely agree.
One thing I want to point out though for anybody not familiar with the differences between podman and docker, for the most part alias docker=podman will "just work" except for these situations:
1. docker-compose. podman-compose attempts to cover this but I've heard it's not quite there yet
2. Mounting the docker socket into the container. Podman is daemonless which means that won't work. There is work going on right now to allow Podman to be driven in a similar way if needed, but I recently tried to set it up and hit a bug[1]. CRI-O brings a daemon, and it is used extensively in Kubernetes and OpenShift, but not so much outside of that.

In Transitioning from Docker to PodmanDisclaimer: I work for Red Hat
As of April 13, 2017 when that blog post went live, Podman did not yet exist. Dan Walsh had not yet made the initial commit that began Podman's life: https://github.com/containers/podman/commit/2b74391cd5281f6f...
So I think it's safe to say that Podman was not mentioned in the article because it did not exist when the article was written.
These days Podman is alive and well. I use it a lot more than Docker now. The fact that Podman can run/create Kubernetes Pods (without needing K8s) is a compelling feature for me.

device controller is present since kernel 4.15.

Docker/Moby supports FUSE-OverlayFS and cgroup2 as well on master. Planned to be released as v20.0X.

Yes w.r.t. cgroup, but the network stuffs (slirp4netns & RootlessKit) were originally written for Docker/Moby :)
> the truth is that container engines run Slirp without the seccomp support
Untrue.

In Rootless ContainersI've been following podman for rootless containers. It works fairly well on Fedora. RHEL 8 works, but has older version of packages compared to Fedora.
There are some fairly well documented shortcomings to consider/work-around. You can find that list at https://github.com/containers/libpod/blob/master/rootless.md
