Only config which contains os-apply-config data should be written to the top level config structure. This change will only top-level configs which are in the group os-apply-config or the default group Heat::Ungrouped. This tripleo-heat-templates change will specify a group for all config resources https://review.openstack.org/#/c/91731/ however the expected top-levels will still be written out without this change. This change is to fix heat software config when the config is not json. Change-Id: I16e42825121cf4968d4b0f0d266f4f6daa962921 Closes-Bug: #1299109
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/lib/os-collect-config/ec2.json:/var/lib/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.
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.↩︎
