Revision as of 10:10, 8 October 2016
Objective
In this exercise we will show how to use jOCCI APIs to look for network resources and attach them to computing resource.
Introduction
Let's suppose to have a running Jyputer Notebook at BIFI with the following VM ID: http://server4-eupt.unizar.es:8787/compute/d380e2a1-0f69-4cf7-8781-1b784a403eed
If you check the VM metadata with the jOCCI-describe-resource, you will find out that this VM has a private network IP address (192.168.68.19). This mean that the server is running behind a NAT server and we need to attach a public network before to access it.
To check the public network interface published by the given cloud provider, please consider the jOCCI-list-resource project:
Listing network resources
Usage
- Access the maven project
]$ cd di4r-traning/jOCCI-list-resources/
- Edit your settings in the src/main/java/it/infn/ct/Exercise2.java source code to list network resources:
String OCCI_ENDPOINT_HOST = "http://server4-eupt.unizar.es:8787/"; // Possible resources are = os_tpl, resource_tpl, compute, storage and network List<String> RESOURCE = Arrays.asList("network");
- Compile and package with maven:

Attach a public network resources
Usage
- Access the maven project
]$ cd di4r-traning/jOCCI-attach-resources/
- Edit your settings in the src/main/java/it/infn/ct/Exercise6.java source code:
List<String> RESOURCE = Arrays.asList("compute", "http://server4-eupt.unizar.es:8787/compute/d380e2a1-0f69-4cf7-8781-1b784a403eed"); String LINK_RESOURCE = ("/network/public");
- Compile and package with maven:
