* Switch `kube-apiserver` port from 443 to 6443 ([#248](https://github.com/poseidon/typhoon/pull/248))
|
||||
* Combine apiserver and ingress NLBs ([#249](https://github.com/poseidon/typhoon/pull/249))
|
||||
* Reduce cost by ~$18/month per cluster. Typhoon AWS clusters now use one network load balancer
|
||||
* Users may keep using CNAME records to `ingress_dns_name` and the `nginx-ingress` addon for Ingress (up to a few million RPS)
|
||||
* Users with heavy traffic (many million RPS) should create a separate NLB(s) for Ingress instead
|

* Worker pools no longer include an extraneous load balancer

* 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 Typhoon for Fedora Atomic ([#200](https://github.com/poseidon/typhoon/issues/200))

In this tutorial, we'll create a Kubernetes v1.10.5 cluster on AWS with Fedora Atomic.
|
||||
|
||||
We'll declare a Kubernetes cluster using the Typhoon Terraform module. Then apply the changes to create a VPC, gateway, subnets, security groups, controller instances, worker auto-scaling group, network load balancers, and TLS assets. Instances are provisioned on first boot with cloud-init.

|

Controllers are provisioned to run an `etcd` peer and a `kubelet` service. Workers run just a `kubelet` service. A one-time [bootkube](https://github.com/kubernetes-incubator/bootkube) bootstrap schedules the `apiserver`, `scheduler`, `controller-manager`, and `kube-dns` on controllers and schedules `kube-proxy` and `calico` (or `flannel`) on every node. A generated `kubeconfig` provides `kubectl` access to the cluster.
