Advanced

Build Image: Go to the root directory where the Dockerfile is in, build image with following command:
```
 docker built -t apacheeagle/sandbox . 
```
The docker image is named apacheeagle/sandbox. Eagle docker image is based on ambari:1.7.0, it will install ganglia, hbase,hive,storm,kafka and so on in this image. Add startup script and buleprint file into image.

```
 docker images
```

Deploy Image: This project also provides helper functions in script eagle-lib.sh for convenience.

 # Firstly, load the helper functions into context
 source eagle-functions

 # Secondly, start to deploy eagle cluster

 # (1) start single-node container
 eagle-deploy-cluster 1 

 # (2) Or muti-node containers
 eagle-deploy-cluster 3

Find IP and Port Mapping: After the container is up and running. The first thing you need to do is finding the IP address and port mapping of the docker container:
```
 docker inspect -f '{{ .NetworkSettings.IPAddress }}' eagle-server
 docker ps
```
Start to use Eagle: Congratulations! You are able to start using Eagle now. Please open eagle ui at following address (username: ADMIN, password: secret by default)
```
 http://{{container_ip}}:9099/eagle-service  
```
Manage Eagle Cluster: This step is about how to managing the eagle cluster though not must-have at starting. Eagle docker depends on Ambari to manage the cluster infrastructure of Eagle. Following are some helpful links:

Ambari UI: http://{{container_ip}}:8080 (username: ADMIN, password: ADMIN)
