## Installing Kubernetes Addons

With kops you manage addons by using kubectl.

Addons in kubernetes are traditionally done by copying files to `/etc/kubernetes/addons` on the master.  But this
doesn't really make sense in HA master configurations.  We also have kubectl available, and addons is just a thin
wrapper over calling kubectl.

This document describes how to install some common addons.

### Dashboard

The [dashboard project](https://github.com/kubernetes/dashboard) provides a nice administrative UI:

Install using:
```
kubectl create -f https://raw.githubusercontent.com/kubernetes/kops/master/addons/kubernetes-dashboard/v1.5.0.yaml
```

And then navigate to `https://api.<clustername>/ui`

(`/ui` is an alias to `https://<clustername>/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard`)

The login credentials are:

* Username: `admin`
* Password: get by running `kops get secrets kube --type secret -oplaintext` or `kubectl config view --minify`


### Monitoring with Heapster - Standalone

Monitoring supports the horizontal pod autoscaler.

Install using:
```
kubectl create -f https://raw.githubusercontent.com/kubernetes/kops/master/addons/monitoring-standalone/v1.2.0.yaml
```
