v0.14.0 is quick follow-up to v0.13.0, upgrading packages and fixing cgroups on some non-systemd-based hosts such as WSL2 and Alpine based tools like colima and rancher-desktop.
Besides the cgroups fix, the update to the latest version of the local-path-provisioner may be a desirable upgrade worth noting with various downstream improvements.
Be sure to see the previous release notes as well!
Breaking Changes
NOTE: The systemd change is from KIND v0.13.0, but we're re-iterating it here since v0.13.0 was so recent.
- systemd cgroups driver will be used for Kubernetes v1.24.0+ (rather than 1.21.0+ when kubeadm changed the default, which we previously overrode).
- NOTE: You must use kind v0.13.0+ with Kubernetes v1.24.0+ images, and if you built your own Kubernetes v1.24.0+ image
with a previous kind version you will need to re-built when switching to kind v0.13.0+. - NOTE: You do not need to be using systemd on the host machine, In kind v0.13.0 we had a bug related to this, it should be fixed this release. systemd is used inside the kind node containers but should not be necessary on the host. We are now using it for Kubernetes pods in addition to running kubelet, containerd etc.
- KIND will continue to use cgroupfs for Kubernetes versions prior to v1.24.0.
- NOTE: You must use kind v0.13.0+ with Kubernetes v1.24.0+ images, and if you built your own Kubernetes v1.24.0+ image
- The default node image is a Kubernetes
v1.24.0image:kindest/node:v1.24.0@sha256:0866296e693efe1fed79d5e6c7af8df71fc73ae45e3679af05342239cdc5bc8e

New Node images have been built for kind v0.14.0, please use these exact images (IE like kindest/node:v1.24.0@sha256:0866296e693efe1fed79d5e6c7af8df71fc73ae45e3679af05342239cdc5bc8e including the digest) or build your own as we may need to change the image format again in the future 😅

Fixes
- fixed running kind with kubernetes v1.24.0+ on some non-systemd-based hosts
- setting migrated kubelet flags in kubelet config where possible, for now we set both the old flags and the config, in some future release we'll set only kubelet config where possible
- fixed kong ingress name in docs
