Learn SALTSTACK with Real Code Examples

Updated Nov 27, 2025

Explain

Manages configuration and state across servers, cloud instances, and containers.

Supports remote execution of commands in parallel across thousands of machines.

Uses a declarative approach with YAML-based SLS files for configuration.

Integrates with cloud providers, orchestration tools, and CI/CD pipelines.

Enables automated provisioning, monitoring, and management of infrastructure.

Core Features

Salt Minions for managed nodes

Salt Master for centralized control

States (SLS) for configuration enforcement

Execution modules for tasks and commands

Reactors for event-driven workflows

Basic Concepts Overview

Master - centralized Salt control node

Minion - agent node managed by Master

State - YAML-based configuration file

Pillar - secure variable storage per minion

Reactor - event-triggered automation system

Project Structure

salt/ - main configuration states directory

salt/<module>/init.sls - module state files

pillar/ - secure variable definitions

top.sls - mapping of states to nodes

roster/ - for Salt SSH node definitions

Building Workflow

Define configuration states in SLS files

Assign states to nodes via top.sls

Apply states with salt-call or salt '*' state.apply
