Umbrella issue for Katacoda removal

[reylejano]

Problem

(The public part of) Katacoda shut down on June 15, 2022
https://www.oreilly.com/online-learning/leveraging-katacoda-technology.html

The remaining part of Katacoda, that Kubernetes uses, is due to shut down late 2022 early 2023.

Related to #33918 and #38785

Discussion

Use the GitHub Discussion to discuss what we should replace Katacoda with.

Specific steps

SIG Docs members propose to edit pages that use Katacoda to mark that the sandbox is unavailable. When an alternative is available then update the affected pages to use the alternative.

It's the place where we work on katacoda at Contribex.

Hey @reylejano Do we have to remove all these pages you've mentioned in the Pages to Update

[reylejano]

@Debanitrkl mentioned on Slack that SIG ContribEx is looking at killercoda

@shannonxtreme mentioned turning the katacoda tutorials to use minikube

Do we as SIG Docs want to continue to maintain these tutorials if they use killercoda or minikube?
Should we turn the tutorials into instructions to use on any Kubernetes cluster?

Imo we can direct users to playgrounds or minikube or whatever (maybe a standard before you begin that says set up a Kubernetes cluster using an option such as X, Y, or Z) and keep our responsibilities scoped to platform agnostic instructions.

I just enjoyed the interactive tutorials, but maintaining their compatibility and maintenance with platform X shouldn't be on SIG Docs

As far as I know, the katacoda examples are using minikube at the moment ?

$ start.sh
Starting Kubernetes...minikube version: v1.18.0
commit: ec61815d60f66a6e4f6353030a40b12362557caa-dirty
* minikube v1.18.0 on Ubuntu 18.04 (amd64)
* Using the none driver based on existing profile

An older version (1.18 vs 1.25), and run from a control plane terminal, but anyway.

---

Note: the "none" driver of minikube is basically just a wrapper around kubeadm

It also deploys the kubernetes dashboard, which is otherwise equally painful to set up.
