v0.11.0

v0.11.0 brings in much sought after support for multi-arch, rootless, dual stack along with a couple of performance fixes.

Breaking Changes

  • The default node image is a Kubernetes v1.21.1 image: kindest/node:v1.21.1@sha256:fae9a58f17f18f06aeac9772ca8b5ac680ebbed985e266f711d936e91d113bad
  • Dropped support for building node images with bazel going forward as part of reducing the build maintenance for Kubernetes. The --type flag is deprecated.
  • The kind build node-image --kube-root flag is deprecated in favor of an argument, using the flag will print a warning. In a future release the flag will be removed.

New Features

  • kind build node-image now supports --arch for cross compiling node images
  • pre-built node images now support arm64 in addition to amd64 (they are multi-arch)
  • Support for running kind with cgroupv2, rootless docker and rootless podman. Please checkout our guide at https://kind.sigs.k8s.io/docs/user/rootless/
  • kindnetd supports dual-stack networking now enabled by default since kubernetes v1.21
  • Internal kubeconfig is now automatically exposed on the control plane nodes for in-cluster access.

New Node images have been built for kind v0.11.0, please use these exact images (IE like kindest/node:v1.21.1@sha256:fae9a58f17f18f06aeac9772ca8b5ac680ebbed985e266f711d936e91d113bad 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 now. It remains possible to build custom images for other architectures (see the docs).

Fixes

  • handle Kubernetes / kubeadm 1.21 breaking cgroups config change.
  • kindnetd now tolerates NoSchedule
  • Fixed kube-proxy CrashLoops by skipping setting nf_conntrack_max
  • Fixed an issue with SIGPIPE errors sometimes failing node startup
  • kind export logs now only exports the version once instead of per node
  • kind export logs always prints export path even if some logs fail to save
  • Fixed a bug where kubeadmConfigPatches weren't merging correctly with generated arguments.
  • Fixed base image build potentially breaking due to file permissions being affected by umask settings on the host.
  • Improved podman support for custom portmaps and zfs, btrfs storage drivers.
  • Fixes for zfs, btrfs storage drivers on docker
