Is docker "a thing" at companies that use Kubernetes?
99% of what you just said is completely incorrect. containerd is not a facade for Docker, in fact the Docker engine is a facade for containerd. The OCI spec is also not a facade for Docker, Docker is simply one application which can create OCI compliant images which can be executed by runtimes like runc. Kubernetes has zero facades for Docker, unless you count the optional open-source cri-dockerd.

Problems with setting up the cluster with kubeadm
Im trying to learn how to set up kubernetes cluster with kubeadm. Im using official kubernetes documentation ( maybe there is a better source?). My goal is to set it up with cri-dockerd and systemd. And to be honest its quite hard task to do it. Informations are scattered arround with links and sometimes its hard to know the order which steps should be executed. I have 2 Virtualbox machines, connected together with NAT network. A master and worker node. I performed these steps on both of them: https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/create-cluster-kubeadm/ Adjust netplan for static IP Adding br_netfilter and overlay to kernel Creating /etc/modules-load.d/k8s.conf with bridging and forwarding https://kubernetes.io/docs/setup/production-environment/container-runtimes/#forwarding-ipv4-and-letting-iptables-see-bridged-traffic Installing docker components https://kubernetes.io/docs/setup/production-environment/container-runtimes/#docker Installing cri-dockerd https://github.com/Mirantis/cri-dockerd Disabling swap install kubeadm kubectl kubelet https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/install-kubeadm/ configure kubelet cgroup driver https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/configure-cgroup-driver/ So currently im at the configuring cgroup driver. I tried to execute kubeadm init kubeadm-config.yaml but kubeadm found 2 CRI endpoints. So i tried to point the correct one with this command kubeadm join --cri-socket /var/run/cri-dockerd.sock but i got discover:Invalid value: ::: bootstrapToken or file must be set And now im completely lost. And also im confused is this a moment for installing CNI (probably i will try with Calico) for pod communication or should i start the cluster first?

Kubernetes Architecture Explained: Worker Nodes in a Cluster
But not to worry, you can still use Docker as a container runtime in Kubernetes using the cri-dockerd adapter. cri-dockerd provides a shim for Docker Engine that lets you control Docker via the Kubernetes CRI. ****

Kubernetes 1.24 Released: What’s New?
As of version 1.24, either one of the other supported runtimes (e.g. containerd or CRI-O) or, in case you still want to rely on Docker Engine, cri-dockerd must be used. Further information on precautions that may be necessary due to the removal of Dockershim is provided by Kubernetes in a guide.

Podman 4.0.0
Kubernetes requires a tool which implements the Container Runtime Interface, a standardized API for starting & managing containers. This is from 2015-2016[1].
For a while Kubernetes has included something called the "dockershim", it's own implementation of a CRI interface that, under the hood, calls Docker or Podman. There's also tools like kind[2] ("kubernetes in docker") that go further- not just hosting Kubernetes worker containers in Docker, but hosting the main kubernetes daemons also in Docker.
Kubernetes deprecated Dockershim, formally in December 2020, but is just throwing the switch now in the upcoming 1.24, expected mid-April[3]. A company Mirantis has pledged to take over support of Dockershim[4], and is calling the new effort "cri-dockerd"[5]. This should allow Kubernetes workers to continue to run via Docker or Podman.
Kind is unaffected, since it runs the main Kubernetes controllers in Docker, which then launch their own opencontainerd (one off the main CRI implementations) inside that Docker container, nested like, so no dockership/cri-dockerd is needed).

Battery consumption of using remote development with WSL2?
Btw #2: For a nice, cross-platform GUI app thing for Docker & Podman here's this one: Podman Desktop Companion.

A long-time Windows power user and game developer is looking for a switch to Linux.
Podman Desktop Companion (cross-platform, supports Docker too)

About to upgrade my wfh machine. Is moving WSL2 environment as simple as export from old > import on new? Also considering move to docker.
Docker in WSL2 too works but with Podman the environment setup may be a little more flexible depending on what you want to achieve on what distro etc. In any case you can use the cross-platform Podman Desktop Companion app to manage your containers via a GUI.
-
Should I be creating a WSL "install" for each project?
Both Distrobox and Podman can be installed without root access btw and, here's a neat little GUI for managing Podman & Docker containers: Podman Desktop Companion (cross-platform).

FYI: Docker is deleting Open Source organisations
No, that's incorrect. Also, there's the unofficial Pods app, and the Podman Desktop Companion.

Windows Docker keeps crashing while running containers
For a GUI to manage your Podman and/or Docker containers, install the Podman Desktop Companion app (yes, it supports both Podman and Docker). They say that the Windows version can be used to manage the containers running in WSL2 but a more sure way would be to pick the Linux app and to install it in the WSL2 distro your containers are installed & running in.

Docker 2.0 went from $11M to $135M in 2 years
I'm skeptic how long this will last unless they bring out some cutting-edge innovations. I frankly used and loved Docker Desktop for a long time because it was the easiest way to get going and I believe even k8s is included now which is great for hobbyists and those who just want to get things done. But, I've been annoyed by the UX changes and the push to login to docker hub.
While in 2023, there are most certainly great alternatives that are relatively easy to install from the terminal and get going, I guess there's not yet a definitive replacement that comes with the GUI too. Best I can think of is Podman Desktop Companion[1] but not sure how well this works.
