+# Kubernetes deployed on multiple ubuntu nodes
+
+This document describes how to deploy kubernetes on multiple ubuntu nodes, including 1 master node and 3 minion nodes, and people uses this approach can scale to **any number of minion nodes** by changing some settings with ease. Although there exists saltstack based ubuntu k8s installation ,  it may be tedious and hard for a guy that knows little about saltstack but want to build a really distributed k8s cluster. This approach is inspired by [k8s deploy on a single node](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/getting-started-guides/ubuntu_single_node.md).       [Cloud team from ZJU](https://github.com/ZJU-SEL) will keep updating this work.
+
+### **Prerequisites：**
+*1 The minion nodes have installed docker version 1.2+* 
+
+*2 All machines can communicate with each orther, no need to connect Internet (should use private docker registry in this case)*
+
+*3 These guide is tested OK on Ubuntu 14.04 LTS 64bit server, but it should also work on most Ubuntu versions*
+
+*4 Dependences of this guide: etcd-2.0.0, flannel-0.2.0, k8s-0.10.1, but it should also work on higher versions*
+
+
+### **Main Steps**
+#### I. Make *kubernetes* , *etcd* and *flanneld* binaries
+
+On your laptop, copy `cluster/ubuntu-cluster` directory to your workspace.
+
+The `build.sh` will download and build all the needed binaries into `./binaries`.
+```
+$ cd cluster/ubuntu-cluster
+$ sudo ./build.sh
+```
+Please copy all the files in `./binaries` into `/opt/bin` of every machine you want to run as Kubernetes cluster node.
+
+
+Alternatively, if your Kubernetes nodes have access to Internet, you can copy `cluster/ubuntu-cluster` directory to every node and run:
+```
+# in every node
+$ cd cluster/ubuntu-cluster
+$ sudo ./build.sh
+$ sudo cp ./binaries/* /opt/bin
+```
+
+
+> We used flannel here because we want to use overlay network, but please remember it is not the only choice, and it is also not a k8s' necessary dependence. Actually you can just build up k8s cluster natively, or use flannel, Open vSwitch or any other SDN tool you like, we just choose flannel here as a example.
+
+#### II. Configue and install every components upstart script
+The example cluster is listed as below:
+
+| IP Address|Role |      
+|---------|------|
+|10.10.103.223| minion|
+|10.10.103.224| minion|
+|10.10.103.162| minion|
+|10.10.103.250| master|
+
+First of all, make sure `cluster/ubuntu-cluster` exists on this node，and run `configue.sh`.
+
+On master( infra1 10.10.103.250 ) node:
+
+```
+# in cluster/ubuntu-cluster
+$ sudo ./configure.sh
+Welcome to use this script to configure k8s setup
+
+Please enter all your cluster node ips, MASTER node comes first
+And separated with blank space like "<ip_1> <ip2> <ip3> 10.10.103.250 10.10.103.223 10.10.103.224 10.10.103.162
+
+This machine acts as
+  both MASTER and MINION:      1
+  only MASTER:                 2
+  only MINION:                 3
+Please choose a role > 2
+
+IP address of this machine > 10.10.103.250
+
+Configure Success
+```
+
+On every minion ( e.g.  10.10.103.224 ) node:
+
+
+```
+# in cluster/ubuntu-cluster
+$ sudo ./configure.sh 
+Welcome to use this script to configure k8s setup
+
+Please enter all your cluster node ips, MASTER node comes first
+And separated with blank space like "<ip_1> <ip2> <ip3> 10.10.103.250 10.10.103.223 10.10.103.224 10.10.103.162
+
+This machine acts as
+  both MASTER and MINION:      1
+  only MASTER:                 2
+  only MINION:                 3
+Please choose a role > 3
+
+IP address of this machine > 10.10.103.224
+
+Configure Success
+```
+
+If you want a node acts as **both running the master and minion**, please choose option 1.
+
+#### III. Start all components
+1. On the master node:
+  
+	`$ sudo service etcd start`
+	
+	Then on every minion node:
+	
+	`$ sudo service etcd start`
+	
+	> The kubernetes commands will be started automatically after etcd
+  
+2. On any node:
+	
+	`$ /opt/bin/etcdctl mk /coreos.com/network/config '{"Network":"10.0.0.0/16"}'`
+	
+	> You can use the below command on another node to comfirm if the network setting is correct.
+	
+	> `$ /opt/bin/etcdctl get /coreos.com/network/config`
+	
+	> If you got `{"Network":"10.0.0.0/16"}`，then etcd cluster is working in good condition. **Victory is in sight！**
+	> If not , you should check` /var/log/upstart/etcd.log` to resolve etcd problem before going forward.
+  
+  
+3. On every minion node
+  
+	> You can use ifconfig to see if there is a new network interface named `flannel0` coming up.
+	
+	> Make sure you have `brctl` installed on every minion, otherwise run `sudo apt-get install bridge-utils`
+	
+	`$ sudo ./reconfigureDocker.sh`
+	
+	This will make the docker daemon aware of flannel network.
+ 
+
+**All done !**
+
+#### IV. Validation
+You can use kubectl command to see if the newly created k8s is working correctly. 
+
+For example , `$ kubectl get minions` to see if you get all your minion nodes comming up. 
+
+Also you can run kubernetes [guest-example](https://github.com/GoogleCloudPlatform/kubernetes/tree/master/examples/guestbook) to build a redis backend cluster on the k8s．
+
+#### V. Trouble Shooting
+
+Generally, what of this guide did is quite simple: 
+
+1. copy bins and files to right dirctories 
+
+2. config etcd using inputed IPs 
+
+3. start flannel network
+
+So, whenver you have problem, do not blame Kubernetes, **check etcd configuration first** 
+
+Please try:
+
+1. Check `/var/log/upstart/etcd.log` for suspicisous etcd log 
+
+2. Check `/etc/default/etcd`, as we do not have much input validation, the right config should be like:
+
+`ETCD_OPTS="-name infra1 -initial-advertise-peer-urls <http://ip_of_this_node:2380> -listen-peer-urls <http://ip_of_this_node:2380> -initial-cluster-token etcd-cluster-1 -initial-cluster infra1=<http://ip_of_this_node:2380>,infra2=<http://ip_of_another_node:2380>,infra3=<http://ip_of_another_node:2380> -initial-cluster-state new"`
+
+3. Remove `data-dir` of etcd and run `reconfigureDocker.sh`again, the default path of `data-dir` is /infra*.etcd/
+
+4. You can also customize your own settings in `/etc/default/{component_name}` after configured success.
