Configuration Management – Ansible, Salt, Chef, Puppet
You need to setup a couple of servers, provision, configure and maintain them? Nowadays there are a couple of configuration management tools available. This week’s 1-pager introduces the 4 most popular ones: Ansible, SaltStack, Chef and Puppet. We try to give an orientation as to which tool to check out first in which context. Of course this is up for debate. No matter what we recommend, there will be differing opinions out there. E.g. at Corinna’s work they use Ansible for more than just a handful of machines. We indicate tendencies, not laws set in stone 🙂Get PDF

Tools for Configuation Management
- work directly on files and system ressources
- little work up front
- easy remote execution
The “Control machine” has “Hosts”. Write “Playbooks” in YAML, which execute sequentially. Needs only ssh and Python.
The “Master” has “Minions”. Write “SaLtState Formulas” in YAML, which execute sequentially.
Many Machines & Clusters:
- abstract – work on modules, define ressources
- maintain several distributions
The “Server” has “Clients”. Write “Recipies” and “Cookbooks” in Ruby DSL, which execute sequentially.
The “Master” has “Agents”. Write “Manifests” in a custom language, which execute in random order.
