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.

macOS Containers v0.0.1
This is a failed attempt to upstream part of containerd changes: https://github.com/containerd/containerd/pull/8789
Other part of containerd changes waits for gods-know-what: https://github.com/containerd/containerd/pull/9054
But I haven't gave up yet.

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/.

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 containerd and cri-o you can also consider the following projects:
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
Moby - The Moby Project - a collaborative project for the container ecosystem to assemble container-based systems
k3s - Lightweight Kubernetes
podman-compose - a script to run docker-compose.yml using podman
minikube - Run Kubernetes locally
colima - Container runtimes on macOS (and Linux) with minimal setup
cri-dockerd - dockerd as a compliant Container Runtime Interface for Kubernetes
sysbox - An open-source, next-generation "runc" that empowers rootless containers to run workloads such as Systemd, Docker, Kubernetes, just like VMs.
