Ian Wienand 51cb5aa4ac Replace openstack.org git:// URLs with https:// 
This is a mechanically generated change to replace openstack.org
git:// URLs with https:// equivalents.

This is in aid of a planned future move of the git hosting
infrastructure to a self-hosted instance of gitea (https://gitea.io),
which does not support the git wire protocol at this stage.

This update should result in no functional change.

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+https://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.↩︎
