Collect and cache metadata, run hooks on changes.
Project description
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.
