cloudmasterd
============
The cloudmasterd daemon runs by default on port 8107 that is proxy passed by
apache from the root context. This daemon provides a REST style interface to
both create new machine instances and manage the existing machine instances.
It also provides a view of the cloud instances available and the amount of
free memory that is available. A cloud consists of multiple cloud instances
(e.g. cloud1.example.org, cloud2.example.org) which in turn host multiple
machine instances (e.g. jboss1.example.org, jboss2.example.org).
Func (https://fedorahosted.org/func) is used to aggregate all the information
from the individual cloud instances to store in a sqlite database on the
cloud master.
Installing
===========
The cloudmasterd service is dependent on several subsystems so in general,
the easiest way to setup a cloud master and a series of cloud instances is
to utilize the genome-replace-self scripts and rekickstart the machine.
You can do this by downloading the genome-replace-self from an internal or
public cobbler machine using:
rpm -i http://$COBBLER_REPO/cobbler/repo_mirror/f8-genome-noarch/genome-replace-self-1.0.0-1.noarch.rpm
and then running the following replace self script which will reformat your
machine as either a cloud master or a cloud minion.
To create a cloud master, you would use the following command:
genome-replace-self -c $COBBLER_REPO
To create a cloud minion, you would use the following command:
genome-replace-self -c $COBBLER_REPO -m "certmaster=$CLOUD_MASTER"
Both forms of the command also support passing in specific cobbler profiles
to allow you to create a RHEL based cloud or use different architectures.
The default profile used is a Fedora 8, 32 bit profile. For example, to use
RHEL5 Update 2 with a 64 bit architecture, you could create a cloud master
using:
genome-replace-self -c $COBBLER_REPO -p GenomeCloud-RHEL5U2-x86_64
The cloudmasterd is also available as a rubygem RPM and can be installed using:
yum install rubygem-cloudmasterd
