Questions tagged [salt-stack]

The Salt Project, previously known as SaltStack, is a Python-based open-source configuration management software and remote execution engine.

Salt is an open source tool to manage your infrastructure. Easy enough to get running in minutes and fast enough to manage tens of thousands of servers and still get a response back in seconds.

Execute arbitrary shell commands or choose from dozens of pre-built modules of common (or complex) commands. Target individual servers or groups of servers based on name, defined roles, or a variety of system information such as hardware, software, operating system, current version, current environment, and many more.

Bring your servers up to a known configured state by writing simple lists of items and defining attributes on those lists.

Why is this commit that sets the RSA public exponent to 1 problematic?

I saw this commit in SaltStack on Hacker News, but I don't understand exactly what it does or why the original version was a cryptography error. (I also don't know a lot about how the specifics of cryptography work, either.) - gen =…

In the Salt system there are grains and pillars. I understand how I can assign custom grains, but when would it be better to consider using pillars?
