CloudMinion is a set of tools for identifying unused OpenStack VMs, setting and managing expiration dates, shutting down and deleting expired VMs.

It consists of the following components:

• cm_agent.pl - Tool which runs on the OpenStack compute nodes and collects info from the VMs by guestmounting them in RO mode.
• cm_manager.pl - Tool for managing the VMs by setting expiration date, shutting down and deleting expired VMS, sending notifications, etc.
• vmem.cgi - GUI for managing the expiration date of the OpenStack VMs.
• Supporting scripts and tools for emailing, running OpenStack commands, etc.

Packages:

• perl-DBD-MySQL needs to be installed on all compute nodes and the management node.
• perl-Mail-Sendmail needs to be installed on the management node

DB:

• A cloud_minion database needs to be created, preferably on the same db host where nova and keystone databases are located.
• An account with create, insert, delete, update, select privileges needs to be created for the above database.
• The account above or another readonly user (with select privileges) needs to have access to nova and keystone databases

CloudMinion Management tools need to be installed on a management node and the agent on all compute nodes.

1. Create a cloud-minion database for this project with user and password, or you can use another existing DB The user needs to have select, insert, update, delete, create privileges
2. Create a read-only user, grant select privileges only to nova and keystone DBs.
3. Pull the CM project https://github.com/paypal/cloudminion.git
4. Update cloudminion/conf/cm.cfg and cloudminion/conf/cm_agent.cfg with values for your cloud
5. Open each file under cloudminion/bin/ and change the base_dir to your installation path
6. Create instance_lifetimes table in the cloud-minion db by running mysql .h .u -p < cloudminion/install/instance_lifetimes.sql

1. Create a base directory for CM, example /opt/cloud_minion, and copy all updated directories and files
2. Install perl-DBD-MySQL and perl-Mail-Sendmail (yum install perl-DBD-MySQL perl-Mail-Sendmail)

1. Create a base directory for CM, example /opt/cloud_minion
2. Copy bin/cm_agent.pl and conf/cm_agent.conf to all nodes under the base_dir
3. Install perl-DBD-MySQL (yum install perl-DBD-MySQL)
