os-apply-config

Collect configuration from cloud metadata sources.

What does it do?

It collects data from defined configuration sources and runs a defined hook whenever the metadata has changed.

Usage

You must define what sources to collect configuration data from in /etc/os-collect-config/sources.ini

The format of this file is

[default]
command=os-refresh-config

[ec2]
type=ec2-metadata

[cfn]
type=cloudformation

These sources will be processed in order, and whenever any of them changes, default.command will be run. OS_CONFIG_FILES will be set in the environment as a colon (":") separated list of the current copy of each metadata source. So in the example above, "os-refresh-config" would be executed with something like this in OS_CONFIG_FILES:

/var/run/os-collect-config/ec2.json:/var/run/os-collect-config/cfn.json

The sources can also be crafted using runtime arguments:

os-collect-config --command=os-refresh-config --source ec2:type=ec2-metadata --source cfn:type=cloudformation

Quick Start

sudo pip install -U git+git://github.com/stackforge/os-collect-config.git

run it on an OpenStack instance with access to ec2 metadata:

os-collect-config --print --source "ec2:ec2-metadata"


That should print out a json representation of the entire ec2 metadata tree.
