v0.17.0 is a small release centered around fixing a bug loading docker hub / docker.io tagged images with identical content but different tags (including images with no explicit host) https://github.com/kubernetes-sigs/kind/pull/2955 and support for cross-architecture kind load ....

This release also ships Kubernetes 1.25.3 and containerd 1.6.9 with their respective fixes.

This release comes to you live from KubeCon NA 2022 😄

Breaking Changes

• The default node image is a Kubernetes v1.25.3 image: kindest/node:v1.25.3@sha256:f52781bc0d7a19fb6c405c2af83abfeb311f130707a0e219175677e366cc45d1
• Internal config generation now defends against yaml-injection
  • This should not be a breaking change if you were using the config fields as documented
  • This does not apply to config patches which are applied after config generation, and by definition patch arbitrary yaml

New Features

• Support for loading cross-architecture images
  • When using kind load docker-image or kind load image-archive, kind now instructs containerd to import all architectures.
  • This means that if you have multi-arch docker run enabled on your host (binfmt_misc qemu-userspace), such as in the Docker Desktop application out-of-the box, you may be able to load and run pods with images for the wrong architecture (e.g. an amd64 image on an M1 mac).
• containerd 1.6.9
• go 1.19.2
• upgraded metallb https://github.com/kubernetes-sigs/kind/pull/2973
• overhauled docs code snippets https://github.com/kubernetes-sigs/kind/pull/2894

New Node images have been built for kind v0.17.0, please use these exact images (IE like kindest/node:v1.25.3@sha256:f52781bc0d7a19fb6c405c2af83abfeb311f130707a0e219175677e366cc45d1 including the digest) or build your own as we may need to change the image format again in the future :sweat_smile:

Additional images known compatible with this release:

• 1.26: kindest/node:v1.26.0@sha256:691e24bd2417609db7e589e1a479b902d2e209892a10ce375fab60a8407c7352

NOTE: These node images support amd64 and arm64. It remains possible to build custom images for other architectures (see the docs).

Fixes

• Fix loading docker hub / docker.io tagged images with identical content but different tags (including images with no explicit host) https://github.com/kubernetes-sigs/kind/pull/2955
• kindnetd (kind's lightweight networking daemonset) now supports removing wrong routes when nodes are added and removed
  • currently, kind does not explicitly have support for adding or removing nodes however, Cluster API Provider Docker (which is based on KIND), does support this.
