I want a Python key namespace utility that lets me do things like this...
# Import from an imaginary package I wish existed...
from keyspace import KeySpace, Key, Prefix
class MyKeys(KeySpace):
prefix_users = Prefix('u')
user_set = Key('users')
KEYS = MyKeys(prefix='prod', delim=':')

Questions & Feedback for SaltStack

Questions & Feedback for SaltStack

I've read as much introduction documentation as I can find. Here are some outstanding questions that I'm still seeking answers for. Links or answers in comments are welcome.

Questions

  1. Is it possible to define salt configurations for different server roles (e.g. webserver, database, loadbalancer, etc) which could be distributed to an arbitrary number of servers? (e.g. one server that is a {webserver,database,loadbalancer} or three servers where each is one of the kid.) I have a feeling this has something to do with Grains, but not sure how.

    Answered: Use grains or nodegroups.
