The deployment failed when using kubectl v1.30.5.

Note: Update source of kubectl to the new bucket supported by k8s official
ref: https://github.com/pipe-cd/pipecd/blob/master/pkg/app/piped/toolregistry/tool_linux.go#L19C9-L19C61

Note: Also check other tool bucket

We can see the available version.

We should use https://dl.k8s.io/ instead of https://storage.googleapis.com/kubernetes-release.

ref: kubernetes/kubernetes#127796 (comment)

https://dl.k8s.io/ is the canonical release host, which is documented at:
https://kubernetes.io/releases/download/
The release note links for downloads: https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.31.md#downloads-for-v1311
https://www.downloadkubernetes.com/
That has been the case for a long time now, it just used to redirect to this google cloud storage bucket. It redirects to a CDN hosted by fastly for more than a year now. https://kubernetes.io/blog/2023/06/09/dl-adopt-cdn/

However that CDN used to be in front of that google.com GCP bucket, now in the latest releases that CDN is in front of a community owned private bucket (to avoid serving user traffic from a single region) instead of the old google.com internal GCP bucket, so releases are no longer possible to fetch from the old bucket which was a leaky implementation detail of dl.k8s.io.

You should avoid depending on the implementation details versus just HTTP(S) download from dl.k8s.io

It affects two files because they use https://storage.googleapis.com/kubernetes-release.

• https://github.com/pipe-cd/pipecd/blob/master/pkg/app/piped/toolregistry/tool_linux.go#L19
• https://github.com/pipe-cd/pipecd/blob/master/pkg/app/piped/toolregistry/tool_darwin.go#L19

Also, kustomize and helm are not affected.

• kustomize is downloaded via github.com
• helm is downloaded via get.helm.sh
