Environment

To deploy a distributed topology it is necessary to define an environment with at least these attributes defined:

• node['eucalyptus']['topology']
• node['eucalyptus']['network']['config-json']

Platforms

This cookbook only supports RHEL/CentOS 7 at the time being.

Berkshelf

A Berksfile is included to allow users to easily download the required cookbook dependencies.

• Install Berkshelf: gem install berkshelf
• Install Deps from inside this cookbook: berks install

Cookbooks

• ntp - sets up NTP for all Eucalyptus servers
• yum - used for managing repositories

Chef server config

Ensure that the following config is set in /etc/chef-server/chef-server.rb: erchef['s3_url_ttl'] = 3600

Usage

For cloud-in-a-box installs look at... Eucadev

For distributed topologies... Deployment with motherbrain

Faststart

Methodology

Faststart is a Bash script, faststart/cloud-in-a-box.sh, that invokes the Eucalyptus cookbook in order to install a single host cloud-in-a-box install. It will package up the Chef cookbooks as a berks package, then install Eucalyptus. To run the Faststart script, from the top level eucalyptus-cookbook directory, execute:

faststart/cloud-in-a-box.sh

Once invoked the script does the following:

1. Checks for necessary resources on the machine that it is installing on (ie disk, memory, virtualization extensions)
2. Asks the user for the minimum necessary configuration parameters.
3. Installs the Chef client
4. Runs the Chef client in order to install Eucalyptus using the cookbook tarball and the inputs from the user.

Inputs from the user are searched and replaced into the templates in faststart/ciab-template.json and fastart/node-template.json and then used as follows to run the cookbook:

chef-client -z -r cookbooks.tgz -j ciab.json
