v0.18.0 - Thanks Docker! 🐳
KIND v0.18.0 Comes with a big shoutout to Docker, Inc. for accepting us into the updated Docker Sponsored OSS Program. Thanks Docker! 🎉
Images should no longer have pull rate limits as a result.
The project will still consider mirroring on or switching primarily to registry.k8s.io in the future, after determining an updated immutable tagging scheme to comply with requirements there.
Otherwise of particular note are a fix for iptables nf_tables v1.8.8+, updated dependencies including runc v1.1.5 with CVE fixes, and a new networking option to control the DNS search list.
Breaking Changes
- The default node image is a Kubernetes
v1.26.3image:kindest/node:v1.26.3@sha256:61b92f38dff6ccc29969e7aa154d34e38b89443af1a2c14e6cfbd2df6419c66f - Dropped support for PPC64LE and S390x, which only had limited support previously
- These platforms had very slow and flaky builds despite attempts at fixing and very limited demand. We've dropped these to focus on the vast majority of our users. These platforms never reached the point of having official node images.
- Removed registry mirror config for
k8s.gcr.io=>registry.k8s.io- k8s.gcr.io is partially redirected already now, and being phased out. Please update your references to use registry.k8s.io directly instead! See: https://registry.k8s.io, https://kubernetes.io/blog/2023/03/10/image-registry-redirect/
New Features
- New
networking.dnsSearchconfig field for overriding the cluster nodes' DNS search list - Documented how to use KIND on chromeOS
- Automated builds for most images
- Improved output for
kind delete cluster
New Node images have been built for kind v0.18.0, please use these exact images (IE like kindest/node:v1.26.3@sha256: 61b92f38dff6ccc29969e7aa154d34e38b89443af1a2c14e6cfbd2df6419c66f including the digest) or build your own as we may need to change the image format again in the future 😅

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 iptables rules when the host has iptables 1.8.8+ in nf_tables (not legacy) mode
- Updated all dependencies to latest as of release time (including go version, go modules, containerd, crictl, runc, local-path-provisioner, base images, ...)
- Package updates are now installed against all packages in the base image when building the kindest/node base image, which should help us stay on top of these
- Fixed containerd snapshotter selection on ZFS hosts
- Generally made containerd snapshotter selection more robust
- Limited haproxy max connections for multiple control-plane node clusters to prevent excessive memory use
- Dedupe nodes correctly in
kind load ... - Documented how to configure and use
kubeadmConfigPatches - Documented default subnets
- Fixed ingress guide "usage" example
- cgroupsv2 CI updated to Fedora 37
- Updated README and site home to use
go installand notgo get(more detailed install docs remain at https://kind.sigs.k8s.io/docs/user/quick-start/#installation) - Documented rootless podman systemd scope fix
