+Ambari-agent Simulator
+============
+This project provides a tool to create a large Ambari-agent cluster in a convenient way.
+
+## Usage:
+Run python launcher_cluster.py to see usage
+
+python launcher_cluster.py request
+
+ request a cluster from GCE, generate the configuration for the cluster. Parameters:
+ <the name of the cluster>, suggestion: {yourname}-group-a)
+ <number of VMs>
+ <number of dockers each VMs>
+ <number of service servers inside VM>
+ <number of ambari-server>, either 0 or 1
+
+python launcher_cluster.py up
+
+ run one cluster, and add to another cluster. Parameters:

+## Introduction to Weave Networking
+[Weave](https://github.com/weaveworks/weave) is a tool to connect Docker containers distributed across different hosts.
+This project use Weave to assign each Docker container (with Ambari-agent) a unique internal IP and a domain name.
+In each VM, a special Docker container will be launched by Weave to act as a Router,
+and to connect all the Docker containers in this VM with other Docker containers in other VMs.
+Also, another special Docker container will be launched by Weave to act as a DNS for this VM.
+Each Docker container can connect with each other by using the internal IP, host name or domain name.
+
+All the Weave internal IP should be configured by the user.
+In this following document, we use subnet 192.168.#.#/16, and use the IP within this subnet to configure Weave.
+Actually, You can use any IP as you wish, even public IP, in which case,
+it will replace the connection to the real outside connection, and redirect the connection to the internal Docker container.
+
+## Quick Start
+With the following 6 steps, you can create a cluster with Ambari-agents, and connect them to your Ambari-server.
+Among all the steps, the step 3 is to configure this program, the step 4 is the one which really matters,
+and other steps act as a one-time configuration or suggestion for your Ambari-server.
+
+You can start with this guide by downloading the code to your own computer or any computers which can access the GCE controller.
+
+* Step 1: Mark down IP of the GCE VM which installed Ambari-server, Ambari_Server_IP=104.196.81.81
+* Step 2: Copy example/config.ini to config/config.ini
+* Step 3: Modify the following values in config/config.ini
+ * Output_folder
+ * GCE_controller_key_file
+ * VM_key_file
+ * cluster_info_file, use {yourname}-group-a
+* Step 4: Use the command line to run 3 VMs, each VM has 5 Ambari-agents.
+
+ python launcher_cluster.py all {yourname}-group-a 3 5 192.168.255.1 Ambari_Server_IP
+
+* Step 5: Log into your Ambari-server machine, run the following command line to set up Weave internal network
+
+ cd agent-simulator/network
+ ./set_ambari_server_network.sh 192.168.255.1 192.168.255.2 16
+
+* Step 6: Operate on Ambari-server web GUI
+ * Add all agents: docker-[0-14]-{yourname}-group-a.weave.local
+ * Choose manual registration
+ * Choose to install HDFS, YARN, HBase, Zookeeper, Ambari-Metrics
+
+
+#### More on Quick Start
+* Step 7: Add one more cluster to your Ambari-server
+ * Modify cluster_info_file in config/config.ini, use {yourname}-group-b
+ * Modify Docker_IP_base in config.config.ini, use 192.168.2.1
+ * Use the command line to run 2 VMs, each VM has 10 Ambari-agents:
+
+ python launcher_cluster.py all {yourname}-group-b 2 10 192.168.255.1 Ambari_Server_IP
+
+ * On Ambari-server web GUI, add all agents: docker-[0-19]-{yourname}-group-b.weave.local
+* Step 8: Add one VM with Ambari-agent installed to your Ambari-server
+ * Log into your VM, set Ambari_Server_IP as the value of server hostname in the file /etc/ambari-agent/conf/ambari-agent.ini
+ * On the VM, Run the following command set up Weave internal network
+
+ cd agent-simulator/network
+ ./set_host_network.sh 192.168.254.1 192.168.254.2 16 Ambari_Server_IP
+
+
+## Detail Work Flow:
+* Step 1: Install Ambari-server
+ * Use existing Ambari-server, or, install and launch a new one
+ * agent-simulator/server/ambari_server_install.sh: this shell might help you install the Ambari-server
+ * agent-simulator/server/ambari_server-_reset_data.sh: this shell might help you set Ambari-server to initial state
+
+* Step 2: Decide IP in your mind
+ * Mark down the IP of the Ambari-server, say {IP of Ambari-server = 104.196.81.81}
+ * Come up a subnet say, {subnet = 192.168.#.#/16} {Docker_IP_mask = 16}
+ * Pick one address closer to the END of the subnet as the Weave INTERNAL IP of Ambari-server,
+ and another one as the Weave DNS IP of Ambari-server,
+ say {Weave IP of Ambari-server = 192.168.255.1} {Weave DNS IP of Ambari-server = 192.168.255.2}
+ * Pick one address closer to the START of the subnet as the Weave INTERNAL IP of the FIRST Ambari-agent,
+ say {Docker_IP_base = 192.168.1.1}
+ * Other Weave INTERNAL IP of Amari-agent will be automatically assigned based on the FIRST one (increasingly).
+
+* Step 3: First time set up Ambari-server
+ * Copy all the agent-simulator code base to Ambari-server
+ * cd agent-simulator/network
+ * Run set_ambari_server_network.sh
+ * In this example, use parameters: {Weave IP of Ambari-server = 192.168.255.1} {Weave DNS IP of Ambari-server = 192.168.255.2} {Docker_IP_mask = 16}
+
+* Step 4: Modify config.ini
+ * Modify attributes: Output_folder, GCE_controller_key_file, GCE_VM_key_file, cluster_info_file
+ * Change Docker_IP_base and Docker_IP_mask, in this example {Docker_IP_base = 192.168.1.1} {Docker_IP_mask = 16}
+
+* Step 5: Request Ambari-agent cluster
+ * Run python launcher_cluster.py request
+ * Use {your name}-group-a as the cluster name. In case you wanna add more cluster to your Ambari-server, change the last letter
+
+* Step 6: Modify Cluster Information File
+ * A TXT file will appear under directory ./config within 1 minutes, which has the information about the cluster
+ * Typically, you would like NameNode, RegionServer, ResourceManager, etc.. to dominate one VM.
+ * In this example, change the configuration of the first and the second VM, make each of them only have one Docker.
+ You can install different server services only into these two Docker containers later on the Ambari-server web GUI.
+
+* Step 7: Run Ambari-agent Cluster
+ Run python launcher_cluster.py run
+ In this exmaple, use parameters: {Weave IP of Ambari-server = 192.168.255.1} {IP of Ambari-server = 104.196.81.81}
+
+* Step 8: Operate on Ambari-server web GUI
+
+
+## Expand Cluster With This Script
+Be careful if you wanna use this script to add more Ambari-agents AGAIN to your Ambari-server
+
+* Use different Cluster Name when providing parameters to launcher_cluster.py
+* In config.ini, use the same Docker_IP_mask, make sure the same subnet
+* Change config.ini to use different Docker_IP_base, make sure that all new IPs never overlap with the existing IPs
+* Change config.ini to use different cluster_info_file, make sure the existing cluster information is not overwritten
+
+## Expand Cluster By Adding other Hosts/VMs
+
+## Naming Convention
+Cluster Name: the name of the cluster must be unique to make sure every VM on GCE has its unique name. The suggestion is using {your name}-group-{a-z}
+
+VM Name: each VM has a domain name assigned by GCE, its host name is {cluster name}-{index}
+
+Docker Container Name: the domain name of Docker container is docker-{index}-{cluster name}.weave.local,
+the prefix "docker" can be configured by value Container_hostname_fix in config/config.ini,
+you can find out which VM has which Docker container in the cluster information file.
+
+
+## Image for Docker Container
+
+## Use Different Partition for Docker Container
+
+## The IP assign mechanism.
+Basically, you don't have to worry about IP. The maximum number of IP is limited by weave_ip_base and weave_ip_mask.
+By fault, the subnet is 192.168.#.#/16. Once you have already created 256*256 agents (the real number is smaller,
+since the DNS on the VM also uses IP address), some address might fall out side of subnet and some fall inside,
+which causes a connection issue. The function related is cluster._increase_ip(). You might want to wrap the IP around,
+but corner cases are always there, there is no silver bullet.
+
+
+## Issues
+* This tool do NOT support parallel usage
+* If GCE has no enough resource, the cluster returned to you will have a smaller number of VM
+* Don't merge your cluster into someone else's cluster. Actually you can do it, but you have to dig into the network, and
+make sure the IP configuration is right.
+
+## Suggestions:
+* Make sure your cluster name is unique, or you might cause trouble to other people's VM
+* Use CTRL + P, then CTRL + Q to exit Docker container. Use "exit" will terminate the container.
+* Remove ~/.ssh/know_hosts files, especially if you run a large cluster.
+You might get a warning from SSH, because the new GCE VM assigned to you might have the same IP with the VMs you saved in know_hosts file.
+Remove .ssh/know_hosts before run this script.
+* Ambari-agent and Ambari-server have to be the same version to successfully register.
+The command used to install Ambari-agent is in the Dockerfile
