b8656fd74b Clarify bare-metal SSH instructions 2018-04-08 14:11:05 -07:00
d276fffcda Fix bare-metal multiple apply/ssh on Terraform v0.11.4+
* Terraform v0.11.4 introduced changes to remote-exec
that mean Typhoon bare-metal clusters require multiple
runs of terraform apply to ssh and bootstrap.
* Bare-metal installs PXE boot a live instance to install
to disk and then reboot from disk as controllers/workers.
Terraform remote-exec has no way to "know" to wait until
the reboot has occurred to kickoff Kubernetes bootstrap.
Previously Typhoon created a "debug" user during this
install phase to allow an admin to SSH, but remote-exec
would hang, trying to connect as user "core". Terraform
v0.11.4 changes this behavior so remote-exec fails and
a user must re-run terraform apply until succeeding.
* A new way to "trick" remote-exec into waiting for the
reboot into the disk install is to run SSH on a non-standard
port during the disk install. This retains the ability
for an admin to SSH during install (most distros don't have
this) and fixes the issue so only a single run of terraform
apply is needed.

6b08bde479 Use k8s.gcr.io instead of gcr.io/google_containers
* Kubernetes recommends using the alias to fetch images
from the nearest GCR regional mirror, to abstract the use
of GCR, and to drop names containing 'google'

7acd4931f6 Remove redundant kubeconfig copy on AWS and GCP
* AWS and Google Cloud make use of auto-scaling groups
and managed instance groups, respectively. As such, the
kubeconfig is already held in cloud user-data
* Controller instances are provisioned with a kubeconfig
from user-data. Its redundant to use a Terraform remote
file copy step for the kubeconfig.

18d08de898 Add Container Linux Config snippet docs 2018-03-18 23:22:40 -07:00
f3730b2bfa Add Container Linux Config snippets feature
* Introduce the ability to support Container Linux Config
"snippets" for controllers and workers on cloud platforms.
This allows end-users to customize hosts by providing Container
Linux configs that are additively merged into the base configs
defined by Typhoon. Config snippets are validated, merged, and
show any errors during `terraform plan`
* Example uses include adding systemd units, network configs,
mounts, files, raid arrays, or other disk provisioning features
provided by Container Linux Configs (using Ignition low-level)
* Requires terraform-provider-ct v0.2.1 plugin

* Leave node-role.kubernetes.io/master="" untouched as its
a Kubernetes convention

45b556c08f Fix overly strict firewall for GCP "worker pools"
* Fix issue where worker firewall rules didn't apply to
additional workers attached to a GCP cluster using the new
"worker pools" feature (unreleased, #148). Solves host
connection timeouts and pods not being scheduled to attached
worker pools.
* Add `name` field to GCP internal worker module to represent
the unique name of of the worker pool
* Use `cluster_name` field of GCP internal worker module for
passing the name of the cluster to which workers should be
attached

da6aafe816 Revert "Add module version requirements to internal workers modules"
* This reverts commit cce4537487.
* Provider passing to child modules is complex and the behavior
changed between Terraform v0.10 and v0.11. We're continuing to
allow both versions so this change should be reverted. For the
time being, those using our internal Terraform modules will have
to be aware of the minimum version for AWS and GCP providers,
there is no good way to do enforcement.

bc967ddcd0 addons: Update CLUO to fix compatability with Kubernetes 1.9
* Update CLUO from v0.4.1 to v0.5.0
* Earlier versions of CLUO fail to drain nodes on Kubernetes 1.9
so nodes drain one at a time repeatedly and Container Linux OS
updates are not applied to nodes.
* Check current OS versions via `kubectl get nodes --show-labels`
2018-01-19 08:33:26 -08:00
ef18f19ec4 Edit digital ocean port range and ordering to suppress diff
* Change port range from keyword "all" to "1-65535", which is the
same but with digitalocean provider 0.1.3 doesn't produce a diff
* Rearrange egress firewall rules to order the Digtial Ocean API
and provider returns. In current testing, this fixes the last diff
that was present on `terraform plan`.
2018-01-15 22:13:59 -08:00
f5efcc1ff8 Relax digitalocean provider version constraints
* Relax fixed 0.1.2 version constraint to "~> 0.1.2", which
allows 0.1.3, 0.1.4, etc, but would not allow 0.2.0

2018-01-15 08:33:44 -08:00
38fa7dff1a Create separate bare-metal container-linux-install profiles
* Create separate container-linux-install profiles (and
cached-container-linux-install) for each node in a cluster
* Fix contention bug on bare-metal during `terraform apply`.
With only a global install profile, terraform would create
(or retain) the profile for each cluster and try to delete
it for each cluster being deleted. As a result, in some cases
apply had to be run multiple times before terraform's repr
of constraints was satisfied (profile deleted and recreated)
* Allow Container Linux install properties to vary between
clusters, such as using a different Container Linux channel
or version for different clusters
2018-01-15 08:23:03 -08:00
bbe295a3f1 Add Terraform v0.11.x support and migration docs

existing clusters (action required!)

## Background
## Motivation
Typhoon powers the author's cloud and colocation clusters. The project has evolved through operational experience and Kubernetes changes. Typhoon is shared under a free license to allow others to use the work freely and contribute to its upkeep.
Typhoon addresses real world needs, which you may share. It is honest about limitations or areas that aren't mature yet. It avoids buzzword bingo and hype. It does not aim to be the one-solution-fits-all distro. An ecosystem of free (or enterprise) Kubernetes distros is healthy.

## Usage
`update-agent` runs as a DaemonSet and annotates a node when `update-engine.service` indiates an update has been installed and a reboot is needed. It also adds additional labels and annotations to nodes.

# Kubernetes Dashboard
The Kubernetes [Dashboard](https://github.com/kubernetes/dashboard) provides a web UI to manage a Kubernetes cluster for those who prefer an alternative to `kubectl`.
## Create
Create the dashboard deployment and service.
```
kubectl apply -f addons/dashboard -R
```
## Access
Use `kubectl` to authenticate to the apiserver and create a local port forward to the remote port on the dashboard pod.
```sh
kubectl get pods -n kube-system
kubectl port-forward POD [LOCAL_PORT:]REMOTE_PORT
kubectl port-forward kubernetes-dashboard-id 9090 -n kube-system
```
!!! tip
If you'd like to expose the Dashboard via Ingress and add authentication, use a suitable OAuth2 proxy sidecar and pick your favorite OAuth2 provider.

## Grafana
Grafana can be used to build dashboards and visualizations that use Prometheus as the datasource. Create the grafana deployment and service.
```
kubectl apply -f addons/grafana -R
```
Use `kubectl` to authenticate to the apiserver and create a local port-forward to the Grafana pod.
