Overview

LocalStack provides a wide range of options for configuring how the emulator behaves. Most users are well served by the defaults, but as your needs grow you can fine-tune everything from logging verbosity to networking and low-level runtime behavior.

This section brings together the settings that control LocalStack itself:

• Configuration Options — the complete reference of environment variables and flags that change how LocalStack starts and runs.
• Logging — control log output and debugging verbosity.
• Networking — how LocalStack exposes endpoints, resolves DNS, and integrates with your local network.
• Advanced Features — power-user topics such as multi-account setups, initialization hooks, and filesystem layout.
