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.

Kubernetes Setup With WSL Control Plane and Raspberry Pi Workers
containerd is required by kubernetes to handle containers on its behalf. A big thanks to the HostAfrica blog for the information on setting containerd up for debain. So the containerd install will need to happen on both the WSL2 instance and the Raspberry Pis. For WSL2 you can just install containerd directly:

Bingo of the Kubernetes problems I found myself debugging over the past weeks. AMA :p
The context deadline exceeded: unknown is also in containerd, and is a known problem.

Hi peeps, I am getting error installing docker. Now let me give you some context. I was trying to install docker on the google colab notebook. As google colab is ubuntu under the hood. So I just followed the docker linux terminal installation commands.

Docker Explained - Again
Docker Desktop adds a bunch of stuff to simplify local development and that’s why it has a larger memory footprint. You don’t use that when deploying but something like https://containerd.io/.
What are some alternatives?
When comparing runtime-spec and containerd you can also consider the following projects:
youki - A container runtime written in Rust
podman - Podman: A tool for managing OCI containers and pods.
cri-o - Open Container Initiative-based implementation of Kubernetes Container Runtime Interface
Moby - The Moby Project - a collaborative project for the container ecosystem to assemble container-based systems
runc - CLI tool for spawning and running containers according to the OCI specification
podman-compose - a script to run docker-compose.yml using podman
crun - A fast and lightweight fully featured OCI runtime and C library for running containers
colima - Container runtimes on macOS (and Linux) with minimal setup
kaniko - Build Container Images In Kubernetes
sysbox - An open-source, next-generation "runc" that empowers rootless containers to run workloads such as Systemd, Docker, Kubernetes, just like VMs.
