kubectl plugin cannot be installed on Apple Silicon (darwin/arm64) (just like #8194)

[joeloplot]

What happened:

$ kubectl krew install ingress-nginx

Updated the local copy of plugin index.
Installing plugin: ingress-nginx
W0814 13:06:56.590627   73494 install.go:164] failed to install plugin "ingress-nginx": plugin "ingress-nginx" does not offer installation for this platform
failed to install some plugins: [ingress-nginx]: plugin "ingress-nginx" does not offer installation for this platform

What you expected to happen:

Installing the plugin

#8194 this seems exactly the same issue, and inexplicably the issue is marked as fixed. Very clearly it isn't fixed. The hacky workaround also doesn't work.

Why is there no ARM build AND no way for the user to build it manually? This plugin is pretty essential.

NGINX Ingress controller version (exec into the pod and run nginx-ingress-controller --version.):

Irrelevant to installing this plugin

Kubernetes version (use kubectl version):

Environment:

• Cloud provider or hardware configuration:

• OS (e.g. from /etc/os-release):

• Kernel (e.g. uname -a):

• Install tools:

  • Please mention how/where was the cluster created like kubeadm/kops/minikube/kind etc.

• Basic cluster related info:

  • kubectl version
  • kubectl get nodes -o wide

• How was the ingress-nginx-controller installed:

  • If helm was used then please show output of helm ls -A | grep -i ingress
  • If helm was used then please show output of helm -n <ingresscontrollernamepspace> get values <helmreleasename>
  • If helm was not used, then copy/paste the complete precise command used to install the controller, along with the flags and options used
  • if you have more than one instance of the ingress-nginx-controller installed in the same cluster, please provide details for all the instances

• Current State of the controller:

  • kubectl describe ingressclasses
  • kubectl -n <ingresscontrollernamespace> get all -A -o wide
  • kubectl -n <ingresscontrollernamespace> describe po <ingresscontrollerpodname>
  • kubectl -n <ingresscontrollernamespace> describe svc <ingresscontrollerservicename>

• Current state of ingress object, if applicable:

  • kubectl -n <appnnamespace> get all,ing -o wide
  • kubectl -n <appnamespace> describe ing <ingressname>
  • If applicable, then, your complete and exact curl/grpcurl command (redacted if required) and the reponse to the curl/grpcurl command with the -v flag

• Others:

  • Any other related information like ;
    • copy/paste of the snippet (if applicable)
    • kubectl describe ... of any custom configmap(s) created and in use
    • Any other related information that may help

@joeloplot I think Apple Silicon (darwin/arm64) is supported. But krew plugin is not up to date. Let me try to update it

[sonbui00]

@joeloplot I've just build a temporary file. You can try

wget https://github.com/sonbui00/ingress-nginx/releases/download/v0.31.2-plugin/ingress-nginx.yaml && kubectl krew install --manifest=ingress-nginx.yaml
