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. For more information see the thread at http://lists.openstack.org/pipermail/openstack-discuss/2019-March/003825.html Change-Id: I5ca82d0b6bf76f8e606922907a608da38c535397

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.
|
|
|
|
.. [#update_svg] 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.
