Welcome to the Linux Foundation Forum!

Exercise 13.3: Adding tools for monitoring and metrics - metrics-server.md missing reporitory

Tried to clone the repository and avter providing my credentials for github i get:
fatal: repository 'https://github.com/kubernetes-incubator/metrics-server.md/' not found
Also tried to go directly to the URL but recieved a 404.

Is the Repository down?

    Step 1 of exercise 13.3 is to clone the repository. This git command just worked for me.

    Step 2 directs you to change into the new directory using cd and run less README.md, which has the "Installation" section and appropriate command and link to the YAML file. Also just worked for me

    As I have just tried these commands and they still work, what commands are you trying, and what errors are you seeing when you try steps 1 and 2?

    The old url (https://github.com/kubernetes-incubator/metrics-server.git) of the metrics-server repository is still working but the course material can perhaps be updated to using the new url (https://github.com/kubernetes-sigs/metrics-server.git).

    This command from Exercise 13.3 - Step 3:

    "kubectl create -f \

    now gives me this error message:

    unable to recognize "https://github.com/kubernetes-sigs/metrics-server/releases/download/v0.3.7/components.yaml": no matches for kind "APIService" in version "apiregistration.k8s.io/v1beta1"

    Simply following the lab exercises I am now at version:

    ient Version: version.Info{Major:"1", Minor:"23", GitVersion:"v1.23.1", GitCommit:"86ec240af8cbd1b60bcc4c03c20da9b98005b92e", GitTreeState:"clean", BuildDate:"2021-12-16T11:41:01Z", GoVersion:"go1.17.5", Compiler:"gc", Platform:"linux/amd64"}

    and the available API is

    $ kubectl api-versions 

    So downloading the components.yaml file first and editing

    apiVersion: apiregistration.k8s.io/v1

    to match fixed the issue.

    Even with that change to the components.yaml, I still got this error:

    1 webhook.go:196] Failed to make webhook authorizer request: the server could not find the requested resource

    double checking the README section again:

    Compatibility Matrix
    Metrics Server  Metrics API group/version   Supported Kubernetes version
    0.6.x   metrics.k8s.io/v1beta1  1.19+
    0.5.x   metrics.k8s.io/v1beta1  *1.8+
    0.4.x   metrics.k8s.io/v1beta1  *1.8+
    0.3.x   metrics.k8s.io/v1beta1  1.8-1.21

    I replaced 0.3.7 with 0.6.1

    Hi @SevenD,

    The README.md also provides the installation command for the latest metrics-server release:
