kind v0.31.0 Kubernetes compatibility release notes

💡 Result:

Summary of kind v0.31.0 Kubernetes compatibility (release highlights)

  • Defaults to Kubernetes v1.35.0 (default node image: kindest/node:v1.35.0@sha256:452d707d...). [1][2]
  • Kubernetes 1.35+ drops cgroup v1 support — kind node images at those Kubernetes versions likewise drop cgroup v1; migrate to cgroup v2 or use older Kubernetes if you must remain on cgroup v1. [2]
  • kubeadm config: prepare for future move from kubeadm v1beta3 → v1beta4 (breaking change to extraArgs); if you use kubeadmConfigPatches, use versioned patches (v1beta3 and v1beta4) and adjust extraArgs shape as needed. kind currently uses v1beta3 for supported versions and is expected to adopt v1beta4 for a future Kubernetes (around 1.36+). [2]
  • Installation/download notes reference v0.31.0 release binaries and go install target sigs.k8s.io/kind@v0.31.0. [1]

Sources: kind documentation (Quick Start / release info) and release notes for v0.31.0. [1] https://kind.sigs.k8s.io/docs/user/quick-start/ [2] release notes summary (v0.31.0).

🌐 Web query:

kind v0.31.0 security advisories CVE

💡 Result:

Short answer: There are no published CVEs that directly affect the kind v0.31.0 client itself. The v0.31.0 release is a dependency/update release (defaults to Kubernetes v1.35.0) and its release notes do not list any kind-specific CVEs. [1][2]

Notes & recommendations:

  • kind node images can include components (containerd, runc, kernel, etc.) that have CVEs; check the exact node image(s) your clusters use (kindest/node:@sha256) and inspect those upstream component advisories. [1][2]
  • Always review the kind releases page and the node image changelogs for security fixes before upgrading. [2]

Sources:

  • kind project site / docs (v0.31.0 references). [1]
  • kind v0.31.0 release notes / releases listing. [2]

sigs.k8s.io kind v0.31.0 breaking changes

💡 Result:

Summary of breaking changes in sigs.k8s.io/kind v0.31.0

  • Default node image bumped to kindest/node:v1.35.0 (digest changed). [1] (gitlab.com)
  • Kubernetes 1.35+ drops cgroup v1 support — kind node images for those Kubernetes versions also drop cgroup v1; if you need cgroup v1, use older Kubernetes images or migrate to cgroup v2. [1] (gitlab.com)
  • Warning about future kubeadm config change: kind will move to kubeadm v1beta4 (breaking change to kubeadm extraArgs) in a future release — prepare if you use kubeadmConfigPatches. [1] (gitlab.com)
  • General note: this release contains dependency updates and defaults Kubernetes version; check release notes for any image- or runtime-related compatibility changes (containerd/cgroup/tooling) that may affect workflows. [2] (github.com)

Sources: [1] kind v0.31.0 release notes / changelog. [2] kind releases page. [1] (gitlab.com) [2] (github.com).

Verify cgroup v2 compatibility before upgrading to kind v0.31.0.

kind v0.31.0 is compatible with Kubernetes 1.35.0 (which it defaults to) and has no security advisories. However, Kubernetes 1.35+ and kind v0.31.0's node images drop cgroup v1 support entirely. Ensure your environment supports cgroup v2 or plan to migrate to it before upgrading. Additionally, prepare for a future kubeadm configuration breaking change (v1beta3 → v1beta4) when kind adopts it for Kubernetes 1.36+.

🤖 Prompt for AI Agents 
In @tools/go.mod at line 8, The change bumps the kind dependency to
sigs.k8s.io/kind v0.31.0 which requires cgroup v2 support in node images; before
merging, verify your runtime and CI environments support cgroup v2 (or plan
migration) and update any docs/README or CI provisioning scripts to check/enable
cgroup v2; if you cannot guarantee cgroup v2 yet, hold the version bump or pin
to the previous kind version and add a TODO comment referencing the eventual
upgrade and the kubeadm v1beta3→v1beta4 breaking change for future kube
versions.
