FHNManager Installation

to be inserted some sign to portlet and the service details (installation, where the packages are located, how to add a cloud and so on)

The Federated Hosting Node Manager (FHNM) is the core part of the gCube-external infrastructures integration.

Usage

Maven coordinates

The maven artifact coordinates are:

<dependency>
   <groupId>org.gcube.resources.federation</groupId>
   <artifactId>fhn-manager-service</artifactId>
   <version>1.0.0-SNAPSHOT</version> 
   <packaging>war</packaging>
</dependency>

Deploy

• Deploy war file to selected SmartGears Container (tomcat Webapp folder)

Authentication

In case of integration with EGI it is necessary to generate a VOMS proxy in order to obtain authorization attributes to be embedded in X.509 proxy certificates, needed to access FedCloud sites.

Ideally, the VRE Manager should have to import the credentials related to own VRE directly from the gCube IS; actually the service foresees an interface for the future integration with the IS, but currently

it is necessary to register a certificate to join a Virtual Organisation (VO) of the cloud. Currenly, we're using VRE Manager certificates (actually a second-level proxy of the manager's cert. The first one is stored, encrypted, in the gCube information system; the second one is generated by the service just before accessing FedCloud and it's really short-lived). Most, if not all, gCube users do not own a x509 certificate; they access the gCube portal with username/password and the usage of external infrastructures is completely transparent to them.

Basically the gCube Information System will contain the .pem certificated associated to each VRE or Infrastructure Manager. Such certificates will be used by the service to create a runtime VOMS proxy in order to interact with FedCloud. If any certificates is provided, no interaction with FedCloud will be allowed.

Set the host environment

• Edit the YAML service.properties file available in WEB.INF/classes folder and replace the STORAGE_DIR: /home/"user_name"/fhnmanager path with user home path (e.g., STORAGE_DIR: /home/ngalante/fhnmanager); such file will contain the persistency of nodes created by using the service.
