v0.14.0

7a5ce5b

v0.14.0

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.
The default node image is a Kubernetes v1.24.0 image: kindest/node:v1.24.0@sha256:0866296e693efe1fed79d5e6c7af8df71fc73ae45e3679af05342239cdc5bc8e

New Features

digest image references should be populated when loading images
base image updates
- crictl v1.24.0
kind binary built with Go 1.18.2
all kindnetd dependencies updated to latest
updated haproxy image
latest local-path-provisioner v0.0.22 with updated packaging
support for Kubernetes v1.25.0-alpha pre-releases builds without the old kubeadm node taint
updated cgroupsv2 CI to Fedora 36

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 😅

NOTE: these node images support amd64 and arm64. It remains possible to build custom images for other architectures (see the docs).

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

v0.13.0

b33b60a

v0.13.0

v0.13.0 is all about cgroups -- We're making the switch to the systemd cgroup driver to align with current Kubernetes container runtime recommendations and kubeadm defaults.

Breaking Changes

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~~, systemd is used inside the kind node containers. We are now using it for Kubernetes pods in addition to running kubelet, containerd etc.
  - UPDATE: There is a bug on hosts that are (cgroupv1, not-systemd) #2765, a fix is pending and the next release will address this. See the linked issue for discussion and workarounds in the meantime.
  - UPDATE: v0.14.0 is released with a fix for this bug. Upgrading should be the preferred solution, but if you need to use v0.13.0 for some reason, see the issue linked above for other workarounds.
- KIND will continue to use cgroupfs for Kubernetes versions prior to v1.24.0.
The default node image is a Kubernetes v1.24.0 image: kindest/node:v1.24.0@sha256:406fd86d48eaf4c04c7280cd1d2ca1d61e7d0d61ddef0125cb097bc7b82ed6a1

New Features

Limited support for PPC64LE architecture (you will need to build your own node images)
kind export logs now dumps a list of images on each node
Base image updates
- Containerd version 1.6.4
- CNI plugins 1.1.1
kind binary built with Go 1.18
General Go dependency updates
registry.k8s.io is used as the primary mirror for k8s.gcr.io in kind nodes / image building
- If registry.k8s.io is not reachable, the node runtime is configured to fallback to k8s.gcr.io directly as the next endpoint

New Node images have been built for kind v0.13.0, please use these exact images (IE like kindest/node:v1.24.0@sha256:406fd86d48eaf4c04c7280cd1d2ca1d61e7d0d61ddef0125cb097bc7b82ed6a1 including the digest) or build your own as we may need to change the image format again in the future 😅

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

Fixes

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.
