Clint Byrum 6b478e9d90 Make heat the default collection method
Previously we were relying on the CFN compatibility API. This makes the
native Heat version the default.

Note that we want to keep full coverage, which is why we are explicitly
adding cfn back in during tests.

os-collect-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 been changed.

Usage

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

The format of this file is:

[default]
command=os-refresh-config

[cfn]
metadata_url=http://192.0.2.99:8000/v1/
access_key_id = ABCDEFGHIJLMNOP01234567890
secret_access_key = 01234567890ABCDEFGHIJKLMNOP
path = MyResource
stack_name = my.stack

These sources will be polled and whenever any of them is changed, default.command will be run. A file will be written to the cache dir, os_config_files.json, which will be a json list of the file paths to the current copy of each metadata source. This list will also be set as a colon separated list in the environment variable OS_CONFIG_FILES for the command that is run. So in the example above, os-refresh-config would be executed with something like this in OS_CONFIG_FILES:

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

The previous version of the metadata from a source (if available) is present at $FILENAME.last.

When run without a command, the metadata sources are printed as a json document.

Quick Start

Install:

sudo pip install -U git+git://git.openstack.org/openstack/os-collect-config.git

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

os-collect-config

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


  1. Recommend using LibreOffice draw to edit os-collect-config-and-friends.odg and regenerate the svg file. Alternatively edit the svg directly, but remove the .odg file if that is done.↩︎
