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 😅

v0.10.0

dfa6e88

v0.10.0

In v0.10.0 the most important changes we're "shipping" are about improving sustainability:

Doubled the set of project owners, granting @aojea & @amwat full access to help maintain the project.
A huge thank you to them for their existing contributions and for stepping up here ❤️
Rewritten and revamped contributor guide https://kind.sigs.k8s.io/docs/contributing/getting-started/

Additionally we're trying a new approach to tracking priorities for v0.11.0 which you can see in our issue tracker.

Otherwise we've made a number of bug fixes and minor improvements.

Some users may appreciate the ability to run kind v0.10.0 (NOT the currently installed v0.7.0) in the free Google Cloud Shell for quick demos, workshops, etc.

Simply install kind somewhere under $HOME and add it to your $PATH to use it in cloud shell:

GO111MODULE=on go get sigs.k8s.io/[email protected]
export PATH="$(go env GOPATH)/bin:${PATH}"
kind create cluster

To persist this PATH for future usage you can edit your $HOME/.bashrc in cloudshell.

Breaking Changes

The default node image is a Kubernetes v1.20.2 image: kindest/node:v1.20.2@sha256:8f7ea6e7642c0da54f04a7ee10431549c0257315b3a634f6ef2fecaaedb19bab
We're only actively supporting Kubernetes v1.14.0+, however limited best effort functionality still encompases v1.13.0 for now.
Images from KIND v0.8.0+ should continue to work for now, but lack various improvements.
udev is explicitly disabled at the node level, though as always please try not to depend on the inner details of nodes beyond providing a particular Kubernetes version with kind
IPv6 pod subnet defaults to /56 instead of /64 (a necessary fix for newer Kubernetes, see #1903)

New Features

kind export logs now includes the kind version
Node images compiled without dockershim for Kubernetes v1.19+ possible, reducing size
Reduced kind binary size further (~7MB) with improved build options
Improved zsh completion
Experimental github actions CI for podman, docker, cgroupsv2
Expanded WSL2 documentation
Revamped contributor guide
Improved docs site implementation, including table of contents generation
Updated dependencies
New Loadbalancer user guide
Better support for running in nested container environments when using images built with v0.10.0+
- This enables cloud shell support

New Node images have been built for kind v0.10.0, please use these exact images (IE like v1.20.2:@sha256:8f7ea6e7642c0da54f04a7ee10431549c0257315b3a634f6ef2fecaaedb19bab including the digest) or build your own as we may need to change the image format again in the future 😅

Fixed development scripts when CDPATH is in use
Fixed building node images with bazel when CWD is not within the source directory
Disabled fancy terminal output when in st (see #1924)
Fixed various typos
Improved cgroups handling
Improved some error messages

v0.9.0

0ff469a

v0.9.0

v0.9.0 Focuses on stability enhancements following v0.8.0 / v0.8.1, a new wave of features will ship in v0.10.0.

Breaking changes have been kept to a minimum, primarily that Kubernetes v1.12.X is no longer supported to make way for some fixes requiring beta-grade kubeadm.

Breaking Changes

The default node image is a Kubernetes v1.19.1 image: kindest/node:v1.19.1@sha256:98cf5288864662e37115e362b23e4369c8c4a408f99cbc06e58ac30ddc721600
Node images built with kind v0.9.0 require using kind v0.9.0+.
- These images should mostly work with older releases but may not work offline.
- Images from kind v0.8.0+ should still work but lack some internal improvements
Support has been dropped for Kubernetes older than v1.13.0.
- A detailed support policy is in the works. The Kubernetes project only supports v1.16+ currently.
- UPDATE: Kubernetes v1.14+ is required for multi-node clusters. See #1744 (comment)
Building Kubernetes with bazel will only work with Kubernetes v1.15+
- Building without bazel still works back to v1.13.0
v1alpha3 kind config is no longer supported. Please upgrade to v1alpha4 (which was already the current version in previous releases)
Capital letters in cluster names are explicitly rejected by kind, in order to prevent encountering upstream issues with name validation

UPDATE: If you are hitting label key and value greater than maximum size (4096 bytes), key: containerd: invalid argument (containerd/cri#1572), then try the following KIND config:

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
containerdConfigPatches:
- |-
  [plugins."io.containerd.grpc.v1.cri".containerd]
  disable_snapshot_annotations = true

See: https://kind.sigs.k8s.io/docs/user/configuration/#getting-started for how to use a KIND config file.

New Features

NFS volumes should now work
Kubernetes RuntimeConfig is now first class in kind config
Upgraded dependencies across the board
Nodes now have a tenative providerID value set. We commit to the kind:// prefix but the rest of the contents may change.
The base image is tentatively multi-arch by default. The node image is still not as of yet.
More values are automatically included in no_proxy when proxies are detected
The default CNI shoult automatically match MTU to the underlying bridge
Binaries are now stripped of debugger (not stacktrace) info for smaller binaries

New Node images have been built for kind v0.9.0, please use these exact images (IE like v1.19.1:@sha256:98cf5288864662e37115e362b23e4369c8c4a408f99cbc06e58ac30ddc721600 including the digest) or build your own as we may need to change the image format again in the future 😅

Fixes

Limited fixes related to HA mode and restart support
Fixed issues with ipv6 network overlap
Fixed bugs with NO_PROXY generation
Mitigated issues with concurrent cluster creation on clean hosts
KUBECONFIG writing has retries to mitigate concurrency / locking issues
Docker data root on ZFS should be fixed
Fixed building with bazel in kubernetes 1.20 development
Implemented assorted workarounds for breaking bugs in podman v2.X
Upstream CNI fixes identified by the project have been upstreamed and picked up to mitigate excessive iptables calls in testing
Replaced broken component IP auto-detection with explicit addresses to work around upstream Kubernetes limitations (pending an agreement on how to move forward upstream)
Fixed some issues with userns-remap support
Fixed port forwarding in some cases

v0.8.1

1170b6b

v0.8.1

This is a tiny patch release to pick up the fix for Can't create ipv4 clusters if ipv6 is disabled at kernel level.

For full release notes please see v0.8.0.

Most users will not need to upgrade to this release, this bug is only known to occur on hosts with the ipv6.disable=1 kernel parameter.

v0.8.0

86a075e

v0.8.0

v0.8.0 Most importantly brings persistent clusters that automatically come back
up after dockerd / host restarts. It also brings a number of fixes to networking
in general, experimental podman backend support, improved failure output, and more.

Breaking Changes

The default node image is a Kubernetes v1.18.2 image: kindest/node:v1.18.2@sha256:7b27a6d0f2517ff88ba444025beae41491b016bc6af573ba467b70c5e8e0d85f
KIND v0.8.0 requires node images built with v0.8.0+.
- These new images should be mostly backwards compatible for kind v0.5.0+
The default docker network for nodes is now kind instead of the default docker bridge
- This enabled many fixes, however if you were running things alongside kind you may need to pass --net=kind
- Your host DNS resolver should just work now ™️ in many cases
- IPv6 clusters no longer require modifying docker daemon config
- Docker networks must have a free IPv6 /64 in the [ULA] range, that is you may
  not create other docker networks consuming the entire ULA range. You can work
  around this by precreating the kind network with some totally other range if you wish.
You may need to migrate to the new featureGates config field when setting feature gates, this should be easier to use though!

NOTE: If you've been experimenting with kind > v0.7.0 installed from HEAD, you may need to docker network rm kind before
creating IPv6 clusters.

New Features

Clusters should not be broken by dockerd restarts / restarting your host!
Host DNS should just work ™️
IPv6 Clusters no longer require modifying docker daemon settings
Kubernetes 1.18+ should work on hosts using the iptables nft backend
kind delete clusters --all for deleting all your clusters
New top level featureGates field in Cluster config for enabling feature gates
Upgraded dependencies broadly, including library packages, go, containerd, CNI, etc...
NO_COLOR (no-color.org) support
Experimental podman support
- These clusters do not survive host reboots
- Requires rootful mode
- Experimental
Improved output on failures, including command output without needing to set -v
Experimentally cross-building the base image for AMD64 + ARM by default
More Documentation! Guide to working with KIND offline, Ingress and more!
New download host and experimental nightly builds
Support for Dynamic PV in Kubernetes 1.11.X
New top level featureGates config option for controlling cluster featuregates
Shiny new WorkGroup-K8s-Infra based infrastructure for Kubernetes CI builds
Support for KIND_CLUSTER_NAME environment variable isntead of --name

v0.7.0

fd64a56

0.7.0

v0.7.0 notably brings greatly improved support for dynamic PersistentVolumes by way of rancher.io/localhost-path integration for clusters with Kubernetes v1.12.X or greater.

It is also worth noting that kind is now committed to IPv6 PR testing and running 80% of the GCE presubmit test cases on Kubernetes Pull Requests.

Breaking Changes

The default node image is a Kubernetes v1.17.0 image kindest/node:v1.17.0@sha256:9512edae126da271b66b990b6fff768fbb7cd786c7d39e86bdf55906352fdf62
Node images built with kind v0.7.0 have many improvements and require kind v0.5.0+, images built with older releases should continue to work.
- To get the new dynamic PV support you must upgrade both kind and your node image(s) to this release or newer. The images are compatible with older releases but only both a newer kind CLI and newer images together will enable the updated PV support.
- When the new PV support enabled by these versions the default storage class is changed from the previous k8s.io/host-path based implementation.

New Features

Dynamic PersistentVolume Support is greatly enhanced with rancher.io/localhost-path integration out of the box
Upgraded dependencies around the board, notably including fixes to the CNI portmap plugin to reduce flakiness
Documentation Enhancements
- We have started an effort to comprehensively cover configuration in the docs
- We have a dedicated guide for using Ingress
- Added more resources
- Improved site code, in particular added copyable snippets
- Other assorted smaller improvements
Again show one box emoji per node being provisioned

New Node have been Images for kind v0.7.0, please use these exact images (IE like kindest/node:v1.16.4@sha256:b91a2c2317a000f3a783489dfb755064177dbc3a0b2f4147d50f04825d016f55) or build your own as we may need to change the image format again in the future 😅

Fixes

Improved messaging in a number of user facing errors
Disabled GINKGO_FLAKE_ATTEMPTS when testing
Fixed local image check
When the default kubeconfig is empty / non-existent, kind create cluster and kind export kubeconfig will preserve extra fields from kubeadm, notably apiVersion and kind (though they are not strictly necessary...)
Reduced cruft in base image

v0.6.1

ffba47b

v0.6.1

This is a small patch release over v0.6.0.

Notably:

Relaxed protocol and propagation in v1alpha4 config to have defaulting like v1alpha3 without specifying a value.
Fixed containerd config patching on clusters with multiple control plane nodes.
Fixed containerd config patching on slow hosts (do not attempt to restart containerd if it has not started yet).
Fixed airgapped support for node images (corrected kindnetd image preloading).

This last point brings a new list of node images, fully compatible with v0.6.0, but with kindnetd properly pre-loaded onto them for use in air-gapped / offline environments:

v0.6.0

5c6fdf0

v0.6.0

v0.6.0 brings major internal rework and some important breaking changes that we hope will make kind easier to use.

It is also worth noting that kind is now used for blocking Kubernetes pull request testing, in addition to already being used for release signal. This is a major milestone for the project.

Breaking Changes

KUBECONFIG is now automatically merged in the same style as kops, minikube, GKE, etc. Please see #1060 for a detailed migration guide.
- You do not need to and should not do export KUBECONFIG="$(kind get kubeconfig-path)". This command is deprecated and will be removed in a future release.
- kind will set your current-context when creating a cluster
- You can configure using a different file by either setting the KUBECONFIG environment variable before creating a cluster, or by setting the --kubeconfig flag on cluster creation
Config files are now parsed in strict mode, which should help catch invalid config files
kind is moving all external (labels, config) namespaced objects into x-k8s.io to comply with the guidelines for API review. For this release kind will support and use both labels without breaking anything, however in a future release we will only use the new x-k8s.io labels. This note is primarily for @danderson 🙃
The default node image is a Kubernetes v1.16.3 image kindest/node:v1.16.3@sha256:bced4bc71380b59873ea3917afe9fb35b00e174d22f50c7cab9188eac2b0fb88
Node images built with kind v0.6.0 have many improvements and require kind v0.5.0+, images built with v0.4.0 / v0.3.0 should continue to work with v0.6.0 however.

New Features

There is a new kind.x-k8s.io/v1alpha4 config format.
- Support for per-node kubeadm config patches
- Support for patching the kind nodes's containerd config, which will be used in an upcoming new guide for local registries
Automatic KUBECONFIG export and merge to simplify using kind.
- kind clusters will always have a kind- prefix in kubeconfig file entries and now can be identified by this.
kind export kubeconfig to re-export credentials in the way kind create cluster now does.
Significant logging rework
- -q / --quiet flag to silence status messages / error output
- Logging with -v 1 / --verbosity 1 or greater will result in detailed error output including stacktraces and command output
Colored terminal output and slightly better spinners.
- You can disable both by setting the environment variable TERM to dumb
Enhanced kind version output with more details
- Builds with make build or make install include git commit
- The simplified version can be obtained with kind version -q
Mounts in extraMounts may have relative paths on the host, resolved against the working directory of kind
kubeadm config patches no longer need to include metadata.name and may optionally exclude the apiVersion, allowing more flexible matching of patches to config objects
- The kind binary is now 75% smaller as a result of eliminating dependencies and writing a patch runtime specific to our needs.
kindnetd now has improved logging with klog
A random salutation is printed at the end of kind create cluster 🙃
It should be possible to install kind via chocolatey with choco install kind. We're also hoping to get a homebrew package shortly!

New Node have been Images for kind v0.5.0, please use these exact images (IE like kindest/node:v1.16.3@sha256:bced4bc71380b59873ea3917afe9fb35b00e174d22f50c7cab9188eac2b0fb88) or build your own as we may need to change the image format again in the future 😅

The new node images for recent Kubernetes versions should be > 200 MB smaller thanks to a KEP we implemented upstream to allow building without most of the in-tree cloud provider code.

Fixes

Various kind CLI output was corrected to be to stdout or stderr where appropriate
We have robust new containerd nightly build infrastructure and are shipping the lastest upstream containerd 1.3 + backports in all node images
Removed unnecessary dependencies and upgraded all dependencies
Fixed building Kubernetes master branch with Bazel
Upgraded to build with Go 1.13.4
Upgraded all dependencies
kindnetd now mounts the iptables xtables lock to ensure coordination with kube-proxy
kind will attempt to recreate the original cgroup environment inside the node, this eliminates some error output from kubelet
fixed a race condition in command execution, eliminating a source of flakiness of some kind commands
kind get kubeconfig does not depend on an existing config file on the host
the product_uuid is now faked to be different per-node
switched to GA storageclass annotation on the default storage class
- removed unnecessary addon manager annotation
kindnetd is now more robust with backoff on failures
kind is now relatively decoupled from docker internally for node management
deflaked our cross build and fixed running it on macOS

Fixes

Worked around Kubernetes build changes pending in v1.16, kind again supports building Kubernetes at HEAD
kind load docker-image now correctly avoids loading images that are already loaded ⚠️
More Node runtime written storage is now on volume(s), this should fix some bugs (#771) and improve performance
New node images will attempt to work around missing /dev/kmsg causing kubelet to not start
/ is rshared in new node (images) for mount propagation (more mounts should be shared now)
LimitNOFILE in the containerd service now matches the updated upstream value (1048576) in new node images
All node level services should be passed proxy environment variables by default now with new node images
Upgraded to build with Go 1.12.9
Upgraded Kustomize to v3.1.0
Bugs in the documentation for using private registries were corrected
