v1.10.9

• Etcd: 3.3.9
• Kubernetes: 1.10.6

v1.10.8: weave 2.4

• Weave: 2.4.0
• Etcd systemd unit default name set to etcd instead of etcd-#{node['name']}
• CoreDNS: 1.2.0
• sdn canal: calico updated to 3.1
• kubeletconfig: explicitly set cgroup driver
• CNI plugins: bump to 0.7.1

v1.11.5

v1.11.4: IPVS proxy mode

• CoreDNS: 1.2.0
• kube-proxy: explicitly set cluster-cidr
• kube-proxy: simplify proxy-mode configuration
• Make kubernetes services network route ipvs compatible
• Packages: install ipvsadm and ipset for IPVS proxy mode
• kube-proxy: split attributes to global and ipvs-related
• sdn canal: calico updated to 3.1

IPVS is now first class citizen.
Just set node['kubernetes']['proxy_mode'] attribute to ipvs and run chef-client.

See official blog post for implementation details.

v1.11.3

• CNI plugins: bump to 0.7.1
• podman: 0.7.1
• cri-o: 1.11.1

v1.11.2: CRIO to the rescue

• Kubelet: add ability to use custom runtimes
• kubeletconfig: check for RotateKubeletServerCertificate feature gate before enabling server certificates autorotation
• Docker moved to separate recipe
• install CRIO and corresponding binaries
• Buildah installation recipe
• Explicitly install aufs-tools if cri-o uses aufs as storage
• kubeletconfig: explicitly set cgroup driver

From now on it's possible to use CRIO instead of docker as a container runtime interface.
Just set node['kubernetes']['container_runtime'] to crio, run chef-client and cleanup docker installation with docker rm -f `docker ps -aq` .
