Kubernetes 101 tutorial does not mention incompatibility with ARM architecture

[lodewijkvankeizerswaard]

What Happened?

I tried to follow the Kubernetes 101 tutorial on my Apple Silicon device. The image used in this tutorial, however, is not compatible with ARM architectures.

The tutorial should make a quick mention of this incompatibility to avoid confusion among new users.

I updated the documentation on a fork, under the impression that I would be able to create a pull request. However, I cannot.

It was updated in the other deployment, unfortunately there is some duplication:

https://kubernetes.io/docs/tutorials/kubernetes-basics/deploy-app/deploy-intro/

There are some other deployments of the same content (including the old Katacoda)

https://kubernetesbootcamp.github.io/kubernetes-bootcamp/

The main issue is that the original tutorial image has not been updated in years...

REPOSITORY                                  TAG       IMAGE ID       CREATED       SIZE

FROM node:slim
EXPOSE 8080
COPY server.js .
CMD node server.js

Yes, I found the other deployment. It was what eventually got me on the right track. Thanks for the clarification.

Although maintaining forks of the same content in parallel is suboptimal, it might still be a good idea to add this note. Do you accept pull requests, or should I consider "this" all I can do for the moment?

A warning in the documentation is OK, but better would be to rebuild the image - like we did for the "echoserver".

• site: Update echo-server image #15397

I'm not sure why they are still using node 6.3.1 instead of upgrading to a later version (currently node 20.12.2 LTS)

@spowelljr : Can the new "bootcamp" image be hosted under kicbase, similar to the new echo-server ?

[spowelljr]

Sure, when I get a second I'll build and push the a multi arch image and update the tutorial
