Is there any way to solve it?

@strongjz Is there any way to solve it?

0.31.0 controller is no longer supported. To my understanding, the plugin version should match the controller version.

Hello @strongjz I have facing the same issue.

I use helm to install nginx in my kubernetes cluster. Currently this is the helm version:

  repository = "https://kubernetes.github.io/ingress-nginx"
  chart      = "ingress-nginx"
  version    = "4.11.3"

At the best of my knowledge it is the latest released by this project.

Looking at the nginx controller image deployed this is what I have:

  Containers:
   controller:
    Image:           registry.k8s.io/ingress-nginx/controller:v1.11.3@sha256:d56f135b6462cfc476447cfe564b83a45e8bb7da2774963b00d12161112270b7
    Ports:           80/TCP, 443/TCP, 8443/TCP
    Host Ports:      0/TCP, 0/TCP, 0/TCP
    SeccompProfile:  RuntimeDefault

I can't find 0.31.0 anywhere in my system, so I am not sure why krew is looking for such version. Unfortunately I am debugging an issue for one of my cluster. I can't really dig deeper, but I will be back with more if I can find what is going on.

In the meantime I am gonna build the plugin from source

Same issue here. Is there any solution for this?

See my related issue filed here in krew repo: kubernetes-sigs/krew-index#4254

This is not a solution but shedding more light on the situation. The plugin definition has not been updated in 4+ years.

There is also a secondary issue, the plugin is based upon the controller releases that used to provide builds for different platforms/architectures. It no longer looks like the release system is providing builds.

Sorry about the ping blast. What needs to be done to get platform/architecture builds reestablished for the above? I can provide the fix in the krew repo but there is nothing to point the plugin definitions at.

I am also unsure of which version would be best for the plugin definition

[threadcrux]

I started to reverse engineer what happened. The MakeFile no longer has a build-plugin target and the associated build-plugin.sh script is missing.

I filed an issue for those here:
#12436

Looks like it was removed here, and then nothing has happened since:
#8812

Not sure why removing the build script for manual building was the idea thrown around. Anyways there is a github action for this but not entirely sure its working
