If you are into Ruby, you have Puppet and Chef.
If you are into Python, you have Ansible and Salt.
If you are into Go, you have Anchor in conjunction with easyssh. But better. Anchor adheres to UNIX philosophy. No bloated code here. But with all due respect to old-generation CM tools, we are standing on the shoulders of giants.
However, as the saying goes,
Good things come in small packages.
Go test drive it. Feedback are welcome but I need to forewarn everyone. Anchor has its own philosophy on configuration management. Do not adapt your previous conception of CM workflow (it’s like a square peg in a round hole).
