access the webui service through kubectl proxy from local machine

[eliassal]

Hi Jerome, I am following your instructions at page 741 at https://container.training/kube-selfpaced.yml.html#741, all works like a charm but one thing I am not able to understand is why you use port 8001 (which works fine) in the command

curl localhost:8001/api/v1/namespaces/yellow/services/webui/proxy/index.html

Webui does not run on 8001, I have deployed all in yellow namespace and running
kubectl get svc
I get

NAME     TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)        AGE
hasher   ClusterIP   10.104.87.206   <none>        80/TCP         26h
redis    ClusterIP   10.97.58.189    <none>        6379/TCP       26h
rng      ClusterIP   10.107.13.239   <none>        80/TCP         26h
webui    NodePort    10.104.163.59   <none>        80:30517/TCP   26h

so how this port 8001 works succesfuly? I am really confused, thanks for your help

@eliassal kubectl proxy listens on port 8001 by default. Please see https://container.training/kube-selfpaced.yml.html#752.

[eliassal]

Yes, @conradwt , I saw that later in the page 752. Thanks for your response

[eliassal]

@conradwt , allow me ask another question please, in page 868, it is indicated to run
kustomize create --resources https://github.com/jpetazzo/kubercoins
I di but getting the error

error: unknown flag: --resources

I remove this flag, I get

error: specify one path to kustomization.yaml

I add -o
kubectl kustomize create https://github.com/jpetazzo/kubercoins -o kustomization.yaml
I get same error

I searched Kustomize github, cant find for CREATE Command

[jpetazzo]

Hi @eliassal,

Sorry for the slow reply 😅

That command should work; I just tried it here:

$ kustomize create --resources https://github.com/jpetazzo/kubercoins
$ kustomize version
5.3.0

But perhaps it requires a relatively new version of kustomize (or, to put it differently: maybe you have a relatively old version of kustomized installed?)

Can you check which version you have, and if you still have that problem with a recent version?

Thanks!

[eliassal]

Merci @jpetazzo my Kustomize is
Kustomize Version: v4.5.7
I visited the github at https://github.com/kubernetes-sigs/kustomize/releases but not indicated how to upgrade.

[jpetazzo]

Ah, it might be a version issue then :)

To upgrade kustomize: use the same method as when you initially installed it.

If you installed it with a package manager (yum apt pacman brew chocolatey...) use that package manager.
If you downloaded the binary and moved it to your $PATH, do that.

Personally I just drop the binary in my ~/bin which is sync'd between my machines, but everyone can do what works best for them!
