The mock third party library was needed for mock support in py2 runtimes. Since we now only support py36 and later, we can use the standard lib unittest.mock module instead. Change-Id: Ib353cf9878334d91e551bf75121413c6fb2222ea

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.
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:
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.
sudo pip install -U git+https://opendev.org/openstack/os-collect-config.git
Run it on an OpenStack instance with access to ec2 metadata:
That 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.↩︎
