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.

The What, Why and How of Containers
> Well, no. When people say "containers", they always mean "Docker".

Containers - entre historia y runtimes
Otras iniciativas empezaron a surgir debido a la alta popularidad de los containers y debido a esto, en 2015 se crea OCI(Open Container Initiative) para definir un estandar para containers(runtimes e imagenes).

Docker is deleting Open Source organisations - what you need to know
Theoretically there could be a lot of new options that pop up. There is an Open Container Initiative that has a Runtime Specification that can be implemented. youki is one example of an OCI-compliant container runtime.

Podman/buildah oci bundle
How I can generate oci bundle that can be run with systemd-nspawn? I've tried podman/buildah push, but generated directory/archive is not an oci bundle (https://github.com/opencontainers/runtime-spec/blob/main/bundle.md). I've tried podman image mount, but config.json file is nowhere to be found. It looks like I am missing something simple.

Youki, a container runtime written in Rust that has passed all integration tests provided by OCI(Open Container Initiative).
In more detail, runC and youki need to implement this specification. https://github.com/opencontainers/runtime-spec

Kubernetes vs Docker: Understanding Containers in 2021
A runtime specification that describes how to unpack and run a container. OCI maintains a reference implementation called runc. Both containerd and CRI-O use runc in the background to spawn containers.

Experimental implementation of container runtime in Rust
The immediate goal of this project(youki) is to pass all the default tests of the runtime-spec that the opencontainers is making. Of course, this is for my own learning, but I believe Rust is one of the best languages to implement a container runtime.

The Road To Kubernetes: How Older Technologies Add Up
Kubernetes on the backend used to utilize docker for much of its container runtime solutions. One of the modular features of Kubernetes is the ability to utilize a Container Runtime Interface or CRI. The problem was that Docker didn't really meet the spec properly and they had to maintain a shim to translate properly. Instead users could utilize the popular containerd or cri-o runtimes. These follow the Open Container Initiative or OCI's guidelines on container formats.

Creating Kubernetes Cluster With CRI-O
Container Runtime Interface (CRI) is one of the important parts of the Kubernetes cluster. It is a plugin interface allowing kubelet to use different container runtimes. And recently CRI-O container runtime has been announced as a CNCF Graduated project. I thought of writing a blog on CRI-O and how to set up a single-node Kubernetes cluster with Kubeadm and CRI-O.

Understanding Docker Architecture: A Beginner's Guide to How Docker Works
CRI-O: This is an open-source container runtime designed for use with Kubernetes. It is a lightweight and stable environment for containers. It also complies with the Kubernetes Container Runtime Interface (CRI), making it easy to integrate with Kubernetes.

How are they doing it?
With CRI-O I believe you can configure registry mirror locations…. Similar to this: https://github.com/cri-o/cri-o/issues/4941

Docker is deleting Open Source organisations - what you need to know
Alternatives like Podman and CRI-O continue to gain traction and may replace Docker in various places. For example, Kubernetes used to use Docker, then moved to containerd, and now also support CRI-O. Generally speaking, the core features of "Docker" are such a commodity now that no one was the wiser when Kubernetes stopped using it.

Container Deep Dive 2: Container Engines
The CRI-O container engine provides a stable, more secure, and performant platform for running Open Container Initiative (OCI) compatible runtimes. CRI-Os purpose is to be the container engine that implements the Kubernetes Container Runtime Interface (CRI) for OpenShift Container Platform and Kubernetes, replacing the Docker service. Source
What are some alternatives?
When comparing runtime-spec and cri-o you can also consider the following projects:
youki - A container runtime written in Rust
containerd - An open and reliable container runtime
podman - Podman: A tool for managing OCI containers and pods.
crun - A fast and lightweight fully featured OCI runtime and C library for running containers
k3s - Lightweight Kubernetes
runc - CLI tool for spawning and running containers according to the OCI specification
minikube - Run Kubernetes locally
cri-dockerd - dockerd as a compliant Container Runtime Interface for Kubernetes
