This reverts commit 9d460a44e4bd0d777ec41a2dc0be6dc80a01a781. The patch being reverted should not have been merged, because setting universal to True is used to claim in-place python 2/3 compatibility in Wheel packages. We don't support python 3 yet, so we must not claim the opposite here (as this would harm end users as soon as we start uploading Wheel packages to PyPi). Please see the following links for details: - http://pythonwheels.com/ - http://lists.openstack.org/pipermail/openstack-dev/2013-November/020059.html Change-Id: I73106d2a1752fa8ee11694c6d9c123a953e6c462
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.stackThese 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/run/os-collect-config/ec2.json:/var/run/os-collect-config/cfn.jsonThe 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.gitRun it on an OpenStack instance with access to ec2 metadata:
os-collect-configThat should print out a json representation of the entire ec2 metadata tree.
