This release brings Kubernetes v1.32.0 to kind by default and fixes kind build node-image for building for Kubernetes releases <v1.31.0 when not building Kubernetes from source (e.g. kind build node-image v1.30.0).

Breaking Changes

• Removed two deprecated flags that had been printing usage warnings for many releases.
  • Removed long-deprecated --kube-root flag from kind build node-image, use --type=source and pass the path as an argument instead.
    • Docs: https://kind.sigs.k8s.io/docs/user/quick-start/#building-images
  • Removed long-deprecated --loglevel flag, use -v / --verbosity instead (see kind help)
• The default node image is now Kubernetes v1.32.0: kindest/node:v1.32.0@sha256:c48c62eac5da28cdadcf560d1d8616cfa6783b58f0d94cf63ad1bf49600cb027

New Features

• Updated to go 1.23.4
• Updated node image dependencies to latest
  • NOTE: you should only be depending on node images to allow kind to create Kubernetes nodes at a given Kubernetes version. The contents of these images are subject to change. However, we have brought everything up to the latest releases which may contain bug fixes.
• Updated local-path-provisioner to v0.30.0
• Refreshed Ingres docs to use https://sigs.k8s.io/cloud-provider-kind

NOTE: You must use the @sha256 digest to guarantee an image built for this release, until such a time as we switch to a different tagging scheme. Even then we will highly encourage digest pinning for security and reproducibility reasons.

NOTE: These node images support amd64 and arm64, both of our supported platforms. You must use the same platform as your host, for more context see #2718

Fixes

• Fixed kind build node-image --type=url and kind build node-image --type=release where Kubernetes version is less than v1.31.0
  • E.G. kind build node-image v1.30.0 and kind build node-image https://dl.k8s.io/v1.30.0/kubernetes-server-linux-arm64.tar.gz
  • This fix will only work for standard release tags (and not pre-releases etc), for those continue to use --type=source.
  • v1.31.0+ will work with all build types for all versions
