## Latest
|
||||
|
||||
* Kubernetes [v1.10.1](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.10.md#v1101)
|
||||
* Enable etcd v3.3 metrics endpoint ([#175](https://github.com/poseidon/typhoon/pull/175))
|
||||
* Use `k8s.gcr.io` instead of `gcr.io/google_containers` ([#180](https://github.com/poseidon/typhoon/pull/180))
|
||||
* Kubernetes [recommends](https://groups.google.com/forum/#!msg/kubernetes-dev/ytjk_rNrTa0/3EFUHvovCAAJ) using the alias to pull from the nearest regional mirror and to abstract the backing container registry
|
||||
* Update kube-dns from v1.14.8 to v1.14.9
|
||||
* Update etcd from v3.3.2 to v3.3.3
|
||||
* Use kubernetes-incubator/bootkube v0.12.0
|
||||
|
||||
#### Bare-Metal
|
||||
|
||||
* Fix need for multiple `terraform apply` runs to create a cluster with Terraform v0.11.4 ([#181](https://github.com/poseidon/typhoon/pull/181))
|
||||
* To SSH during a disk install for debugging, SSH as user "core" with port 2222
|
||||
* Remove the old trick of using a user "debug" during disk install
|
||||
|
||||
#### Google Cloud
|
||||
|
||||
* Refactor out the `controller` internal module
|
||||
|
||||
#### Addons
|
||||
|
||||
* Add Prometheus discovery for etcd peers on controller nodes ([#175](https://github.com/poseidon/typhoon/pull/175))
|
||||
* Scrape etcd v3.3 `--listen-metrics-urls` for metrics
|
||||
* Enable etcd alerts and populate the etcd Grafana dashboard
|
||||
* Update kube-state-metrics from v1.2.0 to v1.3.0
|
||||
|
||||
## v1.10.0
|
||||
|
||||
* Kubernetes [v1.10.0](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.10.md#v1100)
|
||||
* Remove unused, unmaintained `pxe-worker` internal module
|
||||
|
||||
#### AWS
|
||||
|
||||
* Add `disk_type` optional variable for setting the EBS volume type ([#176](https://github.com/poseidon/typhoon/pull/176))
|
||||
* Change default type from `standard` to `gp2`. Prometheus etcd alerts are tuned for fast disks.
|
||||
|
||||
#### Digital Ocean
|
||||
|
||||
* Ensure etcd secrets are only distributed to controller hosts, not workers.
|
||||
* Remove `networking` optional variable. Only flannel works on Digital Ocean.
|
||||
|
||||
#### Google Cloud
|
||||
|
||||
* Add `disk_size` optional variable for setting instance disk size in GB
|
||||
* Add `controller_type` optional variable for setting machine type for controllers
|
||||
* Add `worker_type` optional variable for setting machine type for workers
|
||||
* Remove `machine_type` optional variable. Use `controller_type` and `worker_type`.
|
||||
|
||||
#### Addons
|
||||
|
||||
* Update Grafana from v4.6.3 to v5.0.4 ([#153](https://github.com/poseidon/typhoon/pull/153), [#174](https://github.com/poseidon/typhoon/pull/174))
|
||||
* Restrict dashboard organization role to Viewer
|
||||
|
||||

In this tutorial, we'll network boot and provision a Kubernetes v1.10.1 cluster on bare-metal.
|
||||
|

First, we'll deploy a [Matchbox](https://github.com/coreos/matchbox) service and setup a network boot environment. Then, we'll declare a Kubernetes cluster in Terraform using the Typhoon Terraform module and power on machines. On PXE boot, machines will install Container Linux to disk, reboot into the disk install, and provision themselves as Kubernetes controllers or workers.

In this tutorial, we'll create a Kubernetes v1.10.1 cluster on Google Compute Engine (not GKE).
|

|

We'll declare a Kubernetes cluster in Terraform using the Typhoon Terraform module. On apply, a network, firewall rules, managed instance groups of Kubernetes controllers and workers, network load balancers for controllers and workers, and health checks will be created.
