Piera is a lightweight, pure-Python Hiera parser. It was built to help bridge the gap between Puppet/Hiera and Python system scripts. Piera is currently not feature complete, lacking some less-used interoplation and loading features (feel free to contribute!)
Piera was built at Braintree to help us bridge a gap of emerging Python system scripts, and a historical storage of Puppet/Hiera data.
pip install piera
git clone git@github.com:b1naryth1ef/piera.git
cd piera
python setup.py install
import piera
h = piera.Hiera("my_hiera.yaml")
# You can use piera to simply interact with your structured Hiera data
# key: 'value'
assert h.get("key") == "value"
# key_alias: '%{alias('key')}'
assert h.get("key_alias") == "value"
# key_hiera: 'OHAI %{hiera('key_alias')}'
assert h.get("key_hiera") == "OHAI value"
# Give piera context
assert h.get("my_context_based_key", name='test01', environment='qa') == "context is great!"
