Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

A Gentle Introduction to Containerization and Docker
Even though we will focus on Docker for this article, I wanted to mention that there are more container creation and management tools such as Podman, Rkt, and so on.

A Journey to Find an Ultimate Development Environment
By using containerization, the application will always have the same configuration that is used in the development environment and production environment. There is no more "It works on my machine". Some examples of containerization technologies are Docker and Podman.

Anatomy of Docker
Podman Documentation. Podman is a daemonless container engine for developing, managing, and running OCI Containers on your Linux System.

Exploring Podman: A More Secure Docker Alternative
AFAIK podman either already supports pods in quadlet container files, or will in the near future. https://github.com/containers/podman/pull/20762

Podman Desktop 1.6 released: Even more Kubernetes and Containers features
Podman as a devcontainers engine doesn't currently work if you use devcontainer features [1] or (and this sounds like you're issue) if you use WSL2.
I haven't submitted the WSL2 issue to the Podman team yet. If you get to it before I do, can you like it here?

Oracle data base
You can also use their Oracle Linux Docker images with the database preinstalled using either Podman or Docker. Just make absolutely sure you are downloading something you are licensed to use, because it seems really easy to accidentally infringe copyright via this method.

A call for Podman comparison charts
It's an open source project. https://github.com/containers/podman and https://podman.io - go there, get engaged, see what's going on and most important become part of the community and contribute!

Creating Kubernetes Cluster With CRI-O
It is an open-source, community-driven project which supports OCI-based container registries. It is being maintained by contributors working in Red Hat, Intel, etc. It also comes with a monitoring program known as conmon. Conmon is an OCI container runtime monitor, which makes the communication between CRI-O and runc for a single container.

Which alternative for slirp4netns in rootless containers is better?
When considering using socket activation it's good to know that socket-activation has the advantage that you can create on-demand services. And in the future you might be able to do container image upgrades without loosing an active TCP connection https://github.com/containers/conmon/issues/393 (Right now it's just a feature request that I wrote).
-
Docker is dead?!? Podman - an alternative tool?
This was a wrong assumption. Podman directly uses runC or crun instead of containerd using a technology named conmon. Some more useful information can be found in this article.

Podman: A Daemonless Container Engine
Well, "daemonless" is kind of marketing - there is still this daemon-per-container 'conmon' thing https://github.com/containers/conmon and I don't get why it is needed because 1) who actually needs to re-attach anyway? 2) container's streams are already properly handled by whatever supervisor (e.g. systemd). You can't disable conmon and I'm not sure if its usage is not hardcoded throughout the codebase.
I would very much like to use Podman as a finally proper container launcher in production (non-FAANG scale - at which you maybe start to need k8s), but having an unnecessary daemon moving part in thousands lines of C makes me frown so far.
What are some alternatives?
Portainer - Making Docker and Kubernetes management easy.
runc - CLI tool for spawning and running containers according to the OCI specification
lima - Linux virtual machines, with a focus on running containers
crun - A fast and lightweight fully featured OCI runtime and C library for running containers
kaniko - Build Container Images In Kubernetes
docker - Docker - the open-source application container engine
rancher - Complete container management platform
distribution-spec - OCI Distribution Specification
containerd - An open and reliable container runtime
go - The Go programming language
nerdctl - contaiNERD CTL - Docker-compatible CLI for containerd, with support for Compose, Rootless, eStargz, OCIcrypt, IPFS, ...
