Overview

This skill manages LocalStack extensions to install, uninstall, list, configure, and develop custom extensions that extend LocalStack functionality. It helps discover community extensions, configure runtime settings, and scaffold basic extension code for local cloud development. Use it to integrate tools like MailHog or to add custom HTTP endpoints and hooks into the LocalStack lifecycle.

How this skill works

The skill interacts with the LocalStack extensions command set and the LocalStack extensions API to perform operations: listing installed extensions, installing from PyPI or Git, uninstalling, and toggling enablement. It also guides creating an extension package with required hook methods and HTTP routes, and shows how to configure extensions via environment variables. For troubleshooting, it points to LocalStack logs and compatibility checks.

When to use it

Add third-party integrations or developer tooling to a local cloud environment
Install or remove extensions from a LocalStack instance
Configure extension-specific settings via environment variables
Develop and test a custom LocalStack extension locally
Discover compatible community extensions before adding them

Best practices

Prefer installing released extensions from PyPI or the official extensions registry when available
Install local extensions in editable mode for iterative development (localstack extensions install -e ./my-extension)
Set extension-specific environment variables using the EXTENSION_<NAME>_<SETTING> pattern
Verify extension compatibility with your LocalStack version before installing
Check localstack logs for load-time errors and disable conflicting extensions

Example use cases

Install MailHog extension to capture SES emails and inspect them via a web UI
Add a custom extension that exposes internal debug endpoints for integration tests
Install a version-pinned extension from PyPI to ensure reproducible local environments
Install an extension from a Git repository to evaluate a community contribution or fork
Create an extension that registers lifecycle hooks to initialize test data when LocalStack starts

FAQ

Set the extension-specific enabled environment variable to 0, for example EXTENSION_MAILHOG_ENABLED=0 localstack start -d.

How can I install an extension from a Git repository?

Use the install command with a git URL, for example: localstack extensions install "git+https://github.com/org/extension-repo.git".
