## 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
```
### Route53 Mapper
Please note that kops installs a Route53 DNS controller automatically (it is required for cluster discovery).
The functionality of the route53-mapper overlaps with the dns-controller, but some users will prefer to
use one or the other.
[README for the included dns-controller](https://github.com/kubernetes/kops/blob/master/dns-controller/README.md)
route53-mapper automates creation and updating of entries on Route53 with `A` records pointing
to ELB-backed `LoadBalancer` services created by Kubernetes. Install using:
```
kubectl apply -f https://raw.githubusercontent.com/kubernetes/kops/master/addons/route53-mapper/v1.2.0.yml
```
