Releases: kubernetes-sigs/kind
v0.26.0
This release brings Kubernetes v1.32.0 to kind by default and fixes kind build node-image for building for Kubernetes releases <v1.31.0 when not building Kubernetes from source (e.g. kind build node-image v1.30.0).
Breaking Changes
- Removed two deprecated flags that had been printing usage warnings for many releases.
- Removed long-deprecated
--kube-rootflag fromkind build node-image, use--type=sourceand pass the path as an argument instead. - Removed long-deprecated
--loglevelflag, use-v/--verbosityinstead (seekind help)
- Removed long-deprecated
- The default node image is now Kubernetes v1.32.0:

New Features
- Updated to go 1.23.4
- Updated node image dependencies to latest
- NOTE: you should only be depending on node images to allow kind to create Kubernetes nodes at a given Kubernetes version. The contents of these images are subject to change. However, we have brought everything up to the latest releases which may contain bug fixes.
- Updated local-path-provisioner to v0.30.0
- Refreshed Ingres docs to use https://sigs.k8s.io/cloud-provider-kind

Fixes
- Updated kube-network-policies with a DNS fix for network policies
- Fix conflict with developing kube-network-policies
- Detect new docker ipv6 failure message and fallback to ipv4 only gracefully
- Fixes github codespaces, however we recommend ensuring ip6tables works on your host or at least disabling ipv6 in the docker daemon settings then: https://docs.docker.com/engine/release-notes/27/#ipv6
- Workaround podman no longer returning host IP for portmaps
- Aggregate ipmasq sync errors in kindnetd

v0.24.0
Highlights from this release include network policy support using sigs.k8s.io/kube-network-policies (thanks @aojea!) and support for building node images from pre-compiled Kubernetes releases (thanks @dims!).
For building images, see the docs at https://kind.sigs.k8s.io/docs/user/quick-start/#building-images
Breaking Changes
- The default node image is now Kubernetes v1.31.0:
kindest/node:v1.31.0@sha256:53df588e04085fd41ae12de0c3fe4c72f7013bba32a20e7325357a1ac94ba865
New Features
- Out-of-the-box support for network policy via sigs.k8s.io/kube-network-policies
- Advanced users can still disable kindnetd and install your own CNI with https://kind.sigs.k8s.io/docs/user/configuration/#disable-default-cni, however note that this is a "power user" feature and KIND does not offer support for any third-party CNI
- Support for building node images from existing Kubernetes releases
- NOTE: For Kubernetes releases before v1.31.0, this will result in larger images because kind opted in to compiling out remaining in-tree cloud providers with a build tag when publishing images. For v1.31.0+ there is no difference.
- See: https://kind.sigs.k8s.io/docs/user/quick-start/#building-images
- Support for loading multiple image archives in
kind load image-archive- NOTE: it is still more efficient to do a single archive in most cases
- Migrated to skipPhase in Init/JoinConfiguration instead of the kubeadm flags, making it possible for users to cutomize the phases (at your own risk!) with config patches
- powershell completion
- Updated dependencies, including, but not limited to:
- containerd 1.7.18
- runc 1.1.13
- go 1.22.6
- CNI plugins to 1.5.1
- pause 3.10
- Docs and clarification for third party install options including scoop and winget

v0.23.0
This release introduces initial limited support for nerdctl and kube-proxy nftables mode.
Breaking Changes
- The default node image is now Kubernetes 1.30.0:
kindest/node:v1.30.0@sha256:047357ac0cfea04663786a612ba1eaba9702bef25227a794b52890dd8bcd692e ipFamilyconfig field is now validated- While technically a breaking change, if the value you set here is now caught as invalid it was being silently ignored and creating an ipv4 cluster previously and you should correct your config
- Go 1.17+ is required for
go install sigs.k8s.io/kind/ building thekindbinary- Prebuilt binaries are available as an alternative to
go install - For local development
makewill automatically setup the correct go version - Note that the go team only supports 1.21+ and major linux distros have 1.19+
- Future releases may increase this to a more current Go release
- Future release may adopt
toolchainin go.mod to make this seamless if you have go 1.21+ installed even without our makefile. We highly recommend installing go 1.21+
- Prebuilt binaries are available as an alternative to
New Features
- Initial support for nodes created with nerdctl
- Initial support for
kubeProxyMode: nftables(ahead of Kubernetes 1.31+, see https://kind.sigs.k8s.io/docs/user/configuration/#kube-proxy-mode) - Sweeping dependency updates, see commits for full details. v0.22.0...v0.23.0

v0.21.0
This release patches the recent runc CVEs, as well as an issue with kind build node-image and docker v25.0.0+
Breaking Changes
- The default node image is a Kubernetes
v1.29.1image:kindest/node:v1.29.1@sha256:a0cc28af37cf39b019e2b448c54d1a3f789de32536cb5a5db61a49623e527144
If you haven't already, please see also v0.20.0 release notes which had important announcements that still apply going forward.
New Features
- Upgraded go to 1.20.13
- Upgraded crictl to 1.28
- Upgraded containerd fuse overlayfs to 1.0.6
- Began marking some core images pinned in containerd, which may eventually make enabling imageGC safer
- kindnetd will ignore nodes with empty podCIDR, enabling some niche use-cases

v0.20.0
KIND v0.20.0 fixes runc 1.1.6+ / misc controller support as well as cgroupns support on cgroup v1 and begins the migration to private cgroupns for all kind nodes.
In a future release kind node images will drop support for kind binaries without cgroupns=private (which is already the default on all cgroup v2 hosts, and cgroup v1 in kind v0.20.0). This will allow us to ship a more consistent and reliable environment as the ecosystem heads towards dropping cgroup v1 more generally.
Breaking Changes
- Docker 20.10.0+ is now required, with no change for Podman.
- Node images built with kind v0.20.0+ will be required on cgroups v1 hosts for kind v0.20.0+
- The default node image is a Kubernetes
v1.27.3image:kindest/node:v1.27.3@sha256:3966ac761ae0136263ffdb6cfd4db23ef8a83cba8a463690e98317add2c9ba72
Containerd CRI mirror config deprecation PSA
Additionally, we're asking that everyone using the local registry script update
to the latest version using config_path. https://kind.sigs.k8s.io/docs/user/local-registry/
Containerd deprecated the old CRI mirrors config approach and will remove support in v2.0.
Eventually KIND will enable this by default or have upgraded to containerd 2.0.
Containerd does not support CRI mirror config if the new hosts config_path is enabled.
New Features
- Improved Kubernetes source code path detection in
kind build node-image.- Now searches in this order:
$(pwd),${GOPATH}/src/k8s.io/kubernetes,${GOPATH}/src/github.com/kubernetes/kubernetes(default checkout location in Prow CI withoutpath_alias).
- Now searches in this order:
New node images have been built for kind v0.20.0, please use these exact images (IE like kindest/node:v1.27.3@sha256:3966ac761ae0136263ffdb6cfd4db23ef8a83cba8a463690e98317add2c9ba72 including the digest) or build your own as we may need to change the image format again in the future 😅

- Disabled unused misc controller on cgroups v1 hosts for KIND nodes
- Fixed cgroups on cgroup v1 hosts with cgroupns enabled
- Removed unnecessary flags from haproxy image

v0.19.0
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
v1.27.1image: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
kindbinary or importkindas 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 😅

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

v0.17.0 - Live from KubeCon!
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) #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
v1.25.3image: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-imageorkind load image-archive,
kind now instructs containerd to import all architectures. - This means that if you have multi-arch
docker runenabled 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).
- When using
- containerd 1.6.9
- go 1.19.2
- upgraded metallb #2973
- overhauled docs code snippets #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 😅

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) #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.
- currently, kind does not explicitly have support for adding or removing nodes
