TattrDB is a simple way to add Tags and Attributes to hostnames for use as a very generic service management database.
pip install tattrdb
Tattr uses sqlalchemy underneath and those uses a database url to connect. Once you've constructed your url you can plugin it into the example below:
from tattrdb import models
models._sync(models.connect("sqlite:///tattr.sqlite"))
Using the same url from the example above you'll need to create a configuration file at /etc/tattr.yaml as follows:
db_uri: "sqlite:///tattr.sqlite"
Once you've finished installing and configuring tattr you can use the tattr command line tool to add/rm/modify hosts/tags/attributes. Tattr uses subcommands and each individual subcommand has it's own help messages.
