Perun scripts for FCTF

Description

Scripts integrating cloud middleware used within EGI FCTF with Perun.

Features:

• Creating users
• Removing users (with full clean-up)
• Updating users (credentials, SSH public keys, e-mail addresses)

Installation

Dependencies

OpenNebula

• libxml-xpath-perl (provides perl module XML::XPath and /usr/bin/xpath)
• ruby (used by opennebula-cli)
• opennebula-cli (rubygem, is already present in ON installations)

Notice: RVM is NOT required.

Scripts

• Copy the scripts in this repository to /opt/perun/bin.
• Everything in /opt/perun/bin has to be readable by a user of your choice, e.g. oneadmin.
• /opt/perun/bin/perun must be executable by the same user.

Configuration

Environment

OpenNebula

• ENV variables required by opennebula must be present.
• Group(s) matching VO name(s) must be present in OpenNebula.

Notice: Have a look at fedcloud_export.d/opennebula.d/pre_00_source_opennebula_env_vars.sh and modify it to suit your needs. The example will attempt to load RVM functions and ENV variables from ~/.opennebula.

Notice: The script won't touch users in group oneadmin and users. Group(s) matching VO name(s) will be managed fully (any changes you make manually will be overwritten).

SSH access

• The following SSH public key must be present in ~/.ssh/authorized_keys of the user you chose earlier.
