Action Required

  • action required: the API server and client-go libraries have been fixed to support additional non-alpha-numeric characters in UserInfo "extra" data keys. Both should be updated in order to properly support extra data containing "/" characters or other characters disallowed in HTTP headers. (#65799@dekkagaijin)

  • [action required] The NodeConfiguration kind in the kubeadm v1alpha2 API has been renamed JoinConfiguration in v1alpha3 (#65951@luxas)

  • ACTION REQUIRED: Removes defaulting of CSI file system type to ext4. All the production drivers listed under https://kubernetes-csi.github.io/docs/Drivers.html were inspected and should not be impacted after this change. If you are using a driver not in that list, please test the drivers on an updated test cluster first. ``` (#65499@krunaljain)

  • [action required] The MasterConfiguration kind in the kubeadm v1alpha2 API has been renamed InitConfiguration in v1alpha3 (#65945@luxas)

  • [action required] The formerly publicly-available cAdvisor web UI that the kubelet started using --cadvisor-port is now entirely removed in 1.12. The recommended way to run cAdvisor if you still need it, is via a DaemonSet. (#65707@dims)

  • Cluster Autoscaler version updated to 1.3.1-beta.1. Release notes: https://github.com/kubernetes/autoscaler/releases/tag/cluster-autoscaler-1.3.1-beta.1 (#65857@aleksandra-malinowska)

    • Default value for expendable pod priority cutoff in GCP deployment of Cluster Autoscaler changed from 0 to -10.

    • action required: users deploying workloads with priority lower than 0 may want to use priority lower than -10 to avoid triggering scale-up.

  • [action required] kubeadm: The v1alpha1 config API has been removed. (#65628@luxas)

    • Please convert your v1alpha1 configuration files to v1alpha2 using the

    • kubeadm config migrate command of kubeadm v1.11.x

  • kube-apiserver: the Priority admission plugin is now enabled by default when using --enable-admission-plugins. If using --admission-control to fully specify the set of admission plugins, the Priority admission plugin should be added if using the PodPriority feature, which is enabled by default in 1.11. (#65739@liggitt)

  • The system-node-critical and system-cluster-critical priority classes are now limited to the kube-systemnamespace by the PodPriority admission plugin. (#65593@bsalamat)

  • kubernetes-worker juju charm: Added support for setting the --enable-ssl-chain-completion option on the ingress proxy. "action required": if your installation relies on supplying incomplete certificate chains and using OCSP to fill them in, you must set "ingress-ssl-chain-completion" to "true" in your juju configuration. (#63845@paulgear)
