This release contains many exciting features! Amongst other things we now have support for multi-node clusters thanks to @fabriziopandini, and fixes have been made for kind on Windows.

UPDATE 2019-02-11

Due to CVE-2019-5736 ("the runc escape")

kindest/node:v1.13.2@sha256:d070e091e7c0e515a37d0834ea72828b2338acdc4bc7a13cbb84274fb14e5e83 or: kindest/node:v1.13.3@sha256:d1af504f20f3450ccb7aed63b67ec61c156f9ed3e8b0d973b3dee3c95991753c

Should be used instead of the default image in this release. Example:

kind create cluster --image=kindest/node:v1.13.3@sha256:d1af504f20f3450ccb7aed63b67ec61c156f9ed3e8b0d973b3dee3c95991753c

In the future we are looking at not pinning to an exact image by default, so that minimal fixes can be silently pushed. We are additionally hoping to adopt rootless containers once support lands in Kubernetes.

Breaking changes since 0.1.0

• Default clusters will now be Kubernetes v1.13.2, and the default node image is now kindest/node:v1.13.2@sha256:e14edfa4950e009fe560499c9db6e89daae8bd18bcb372caca6d321a86c52cda
• nodeLifecycleHooks are no longer supported in the config, we believe this feature was unused and will revisit it later, if you need this, please file an issue with your use case!
• Deleting a cluster now attempts to delete the cluster specific KUBECONFIG file on the host (thanks @blakestoddard!)

New Features

• The current kind Config is now at kind.sigs.k8s.io/v1alpha2, with support for multi-node clusters! (thanks @fabriziopandini!)
• The default image was upgraded to Kubernetes v1.13.2 (see above)
• kind should now work on hosts where userns remap is enabled in the docker daemon (thanks @vasrem!)
• Improved documentation (thanks @alejandrox1, @jimangel, @tao12345666333, @k8k, @timoreimann, @chuckha, @superbrothers, @benmoss!)
• kubeadm's config is now internally v1beta1 when new enough Kubernetes images are used, this should improve stable support for future Kubernetes versions. Additionally all config objects are populated, so they may be patched via patches in kind's config.
• When removing a KUBECONFIG file, we attempt to detect if the environment variable is set and warn about unsetting it (thanks @blakestoddard, @manparvesh!)
• The base image now contains conntrack, in order to support installing recent kubeadm packages. by default it is now kindest/base:v20181203-d055041
• kind build node-image now supports a --kube-root flag to explicitly specify the path to Kubernetes's source code, if unset kind will continue to auto-detect this via go's build tooling. (thanks @inercia!)

Fixes

• On Windows the KUBECONFIG files should now be placed in the default directory correctly (we now use the homedir util from client-go)
• On Windows patching kubeadm config should work correctly
• Recent kubeadm debian packages should be installable in the base image after adding conntrack (see above)
