AWS

  • Switch kube-apiserver port from 443 to 6443 (#248)
  • Combine apiserver and ingress NLBs (#249)
    • Reduce cost by ~$18/month per cluster. Typhoon AWS clusters now use one network load balancer.
    • Ingress addon users may keep using CNAME records to the ingress_dns_name module output (few million RPS)
    • Ingress users with heavy traffic (many million RPS) should create a separate NLB(s)
  • Worker pools no longer include an extraneous load balancer. Remove worker module's ingress_dns_name output

    • Users who exposed kube-apiserver on a WAN via their router/load-balancer will need to adjust its configuration (e.g. DNAT 6443). Most apiservers are on a LAN (internal, VPN-only, etc) so if you didn't specially configure network gear for 443, no change is needed. (possible action required)
  • Fix possible deadlock when provisioning clusters larger than 10 nodes (#244)

DigitalOcean

  • Switch kube-apiserver port from 443 to 6443 (#248)
    • Update firewall rules and generated kubeconfig's

Google Cloud

    • Switch Ingress from regional network load balancers to global HTTP/TCP Proxy load balancing
    • Reduce cost by ~$19/month per cluster. Google bills the first 5 global and regional forwarding rules separately. Typhoon clusters now use 3 global and 0 regional forwarding rules.
  • Worker pools no longer include an extraneous load balancer. Remove worker module's ingress_static_ip output
  • Allow using nginx-ingress addon on Fedora Atomic clusters (#200)
  • Add worker_instance_group module output to allow custom global load balancing
  • Add instance_group worker module output to allow custom global load balancing
  • Deprecate ingress_static_ip module output. Add ingress_static_ipv4 module output instead.

  • Drop hostNetwork from nginx-ingress addon
    • Both flannel and Calico support host port via portmap
    • Allows writing NetworkPolicies that reference ingress pods in from or to. HostNetwork pods were difficult to write network policy for since they could circumvent the CNI network to communicate with pods on the same node.

v1.10.4

  • Kubernetes v1.10.4
  • Update etcd from v3.3.5 to v3.3.6
  • Update Calico from v3.1.2 to v3.1.3
