Docker is dead?!? Podman - an alternative tool?
Another possibility to switch from Docker containers are the so-called Unikernels. These are briefly mentioned here for the sake of completeness, even though they currently have no significance in the Kubernetes context. An interesting blog post on the topic can be found on Hackernoon. It is an interesting construct that may one day find its way into the world of Kubernetes if containers can be replaced by unikernels. Currently, the use of unikernels would not be feasible in my opinion.

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/.
What are some alternatives?
podman - Podman: A tool for managing OCI containers and pods.
nanos - A kernel designed to run one and only one application in a virtualized environment
cri-o - Open Container Initiative-based implementation of Kubernetes Container Runtime Interface
k3d - Little helper to run CNCF's k3s in Docker
Moby - The Moby Project - a collaborative project for the container ecosystem to assemble container-based systems
nerdctl - contaiNERD CTL - Docker-compatible CLI for containerd, with support for Compose, Rootless, eStargz, OCIcrypt, IPFS, ...
podman-compose - a script to run docker-compose.yml using podman
colima - Container runtimes on macOS (and Linux) with minimal setup
sysbox - An open-source, next-generation "runc" that empowers rootless containers to run workloads such as Systemd, Docker, Kubernetes, just like VMs.
cri-dockerd - dockerd as a compliant Container Runtime Interface for Kubernetes
gvisor - Application Kernel for Containers
