KIND v0.19.0 contains a fix for airgapped node image usage and a significant overhaul over our base image and dependency management.

KIND node images now contain a LICENSE/ directory based on go-licenses for all external go binaries, all external go binaries are built from source and contain fully patched go as of the time of release, streamlining that process and decoupling versions.

Since this release comes shortly after v0.18.0, we highly recommend seeing v0.18.0 release notes as well.

Breaking Changes

  • The default node image is a Kubernetes v1.27.1 image: kindest/node:v1.27.1@sha256:b7d12ed662b873bd8510879c1846e87c7e676a79fefc93e17b2a52989d3ff42b
  • Base distro is now Debian, not Ubuntu.
    • While it is not supported to depend on the contents of these images beyond providing what KIND needs to create a functioning Kubernetes cluster at a given version, we know some power users depend on this anyhow. This is your warning! This is subject to change again in the future. We also dropped some now-unnecessary packages from the image.
  • Go 1.16+ is now required to build the kind binary or import kind as a library (much more recent Go 1.20.4 was used for release builds, but 1.16 is the minimum required version now)

New Features

  • Smaller node image containerd binaries with unusable snapshotters compiled out
  • LICENSES/ directory in all node / base images with license info for all dependent packages / binaries contained in images that don't come from the base distro (other packages are covered by distro standard metadata)

New node images have been built for kind v0.19.0, 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: You must use the @sha256 digest to guarantee an image built for this release, until such a time as we switch to a different tagging scheme. Even then we will highly encourage digest pinning for security and reproducibility reasons.

See also:

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 airgap preloading for kindnetd and local-path-provisioner
  • podman: detect disabled IPv6 and create IPv4 only network instead
  • Overhauled image building, fully patched all dependencies and build toolchains
  • Updated containerd, crictl, CNI plugins, local-path-provisioner ... etc
  • Dropped unnecessary packages from image
  • Fixed dockerized site build on non-amd64 hosts
