= Scope =
 
−
This library has been developed in order to allow the integration of gcube with EGI FedCloud infrastructure.
 
−
In particular, the usage of the library will facilitate the interaction with the sites exposing OCCI just by manipulating APIs.

= Usage =

== Maven coordinates ==
 
−
The maven artifact coordinates are:
 
−
<dependency>
 
−
  <groupId>org.gcube.dvos</groupId>
 
−
  <artifactId>occi-library</artifactId>
 
−
  <version>1.0.0-SNAPSHOT</version>
 
−
</dependency>
 
  
−
Check on [http://maven.research-infrastructures.eu/nexus/index.html#nexus-search;quick~database-resource Nexus] for the latest version.
 
−
= APIs =
 
−
In the following the functionalities proposed by the library are shown.
 
−
 
−
== Site Connection ==
 
−
=== VOMS proxy generation ===
 
−
In order to access the EGI FedCloud infrastructure it is necessary to create a VOMS proxy certificate.
 
−
Open a shell and run the following command:
 
−
<source lang="html4strict">
 
−
$voms-proxy-init --voms fedcloud.egi.eu --rfc --dont-verify-ac
 
−
</source >
 
−
Later it is necessary to digit the own EGI identity grid password.
 
−
<source lang="html4strict">
 
−
Enter GRID pass phrase for this identity:
 
−
Your identity: /C=IT/O=INFN/OU=Personal Certificate/L=ENGINEERING RDLAB/CN=Nunzio Andrea Galante

−
=== Authentication ===
 
−
The library provides both VOMS and X509 access authentication methods.
 
−
A list of sites exposing OCCI and endorsed by FedCloud VO is available at [https://appdb.egi.eu/ Appdb repository].
 
−
<source lang = java>
 
−
String a = X509CredentialManager.createProxy("/tmp/your_proxy.pem", ""); //2nd level proxy
 
−
FedcloudOCCI jocci = new FedcloudOCCI("endpoint");
 
−
//FedcloudOCCI jocci = new FedcloudOCCI("https://carach5.ics.muni.cz:11443");
 
−
jocci.setCertificate(a);
 
−
jocci.setTrustStore("CA Path certificates");
 
−
</source>
 
−
=== Endpoint Connection ===
 
−
<source lang = java>
 
−
jocci.connect();

== Resources Management ==
 
−
=== Setting Contextualization script ===
 
−
Three different options of providing a contextualization script to a resource when it has to be create are available.
 
−
 
−
1. By using the content of a public URL
 
−
<source lang = java>
 
−
String c = "https://appdb.egi.eu/storage/cs/vapp/15819120-7ee4-4b85-818a-d9bd755a61f0/devsec-init";
 
−
URL context = new URL(c);
 
−
</source>
 
−
2. By passing the content of a script via local file
 
−
<source lang = java>
 
−
String path = "/my/local/path/script.sh";
 
−
File f = new File(path);
 
−
</source>
 
−
3. Providing directly the content of the script in the code (deprecated option)
 
−
<source lang = java>
 
−
String gcube_script = "#!/bin/bash \n"  +
 
−
              "export SCOPE=devsec \n"+
 
−
          "export INFRA_NAME=gcube \n"+
 
−
              "export LOCATION=pisa \n"+
 
−
          "export COUNTRY=IT \n"+
 
−
          "/usr/local/bin/smartgears-setup";
 
−
</source>
 
−
=== Creating and describing resource ===
 
−
To create a compute it is necessary to specify the OS and Resources templates for the image.
 
−
<source lang = java>
 
−
Mixin os = jocci.getOsTemplateList().get(0); //first os template avilable
 
−
Mixin resource = jocci.getResourcesTemplateList().get(0); //first resource template available in the list
 
−
</source>
 
−
Alternatively we can specify directly the Virtual Appliance we want to refer to :
 
−
<source lang = java>
 
−
      Mixin os = null;
 
−
      for (int i=0; i < jocci.getOsTemplateList().size(); i++) {
 
−
os = jocci.getOsTemplateList().get(i);//gcube OS template available in the list
 
−
if (os.getTerm().equals("uuid_gcubesmartexecutorv4_fedcloud_warg_142"))
 
−
break;
 
−
}
 
−
</source>
 
−
Depending on the typology of contextualization script to upload, it is possible to use four different approacches to create the resource:
 
−
<source lang = java>
 
−
jocci.createComputeAndDescribe(os,resource,"Resource name"); //no context script
 
−
jocci.createComputeAndDescribe(os,resource,"Resource name",context); //Script from URI
 
−
jocci.createComputeAndDescribe(os,resource,"Resource name",f); //Script from file
 
−
jocci.createComputeAndDescribe(os,resource,"Resource name",gcube_script); //String option
 
−
</source>
 
−
An example of output is the following:
 
−
<source lang = "text">
