## Getting started on Ubuntu
This document describes how to get started to run kubernetes services on a single host (whihch is acting both as master and minion) for ubuntu systems. It consistes of three steps
1. Make kubernetes and etcd binaries
2. Install upstart scripts
3. Customizing ubuntu launch
### 1. Make kubernetes and etcd binaries
Either build or download the latest [kubernetest binaries] (https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/getting-started-guides/binary_release.md)
Copy the kube binaries into `/opt/bin` or a path of your choice
Similarly pull an `etcd` binary from [etcd releases](https://github.com/coreos/etcd/releases) or build the `etcd` yourself using instructions at [https://github.com/coreos/etcd](https://github.com/coreos/etcd)
Copy the `etcd` binary into `/opt/bin` or path of your choice
### 2. Install upstart scripts
Running ubuntu/util.sh would install/copy the scripts for upstart to pick up. The script may warn you on some valid problems/conditions
```
$ cd kubernetes/cluster/ubuntu
$ sudo ./util.sh
```
After this the kubernetes and `etcd` services would be up and running. You can use `service start/stop/restart/force-reload` on the services.
Luanching and scheduling containers using kubecfg can also be used at this point, as explained mentioned in the [examples](https://github.com/GoogleCloudPlatform/kubernetes/tree/master/examples/guestbook)
### 3. Customizing the ubuntu launch
To customize the defaults you will need to tweak `/etc/default/kube*` files and restart the appropriate services. This is needed if the binaries are copied in a place other than `/opt/bin`. A run could look like
```
$ sudo cat /etc/default/etcd
# Etcd Upstart and SysVinit configuration file
# Customize etcd location
# ETCD="/opt/bin/etcd"
# Use ETCD_OPTS to modify the start/restart options
ETCD_OPTS="-listen-client-urls=http://127.0.0.1:4001"
# Add more envionrment settings used by etcd here
$ sudo service etcd status
etcd start/running, process 834
$ sudo service etcd restart
etcd stop/waiting
etcd start/running, process 29050
```
