Getting Started

LocalStack is a cloud service emulator that runs in a single container on your laptop or in your CI environment. With LocalStack, you can run your AWS applications or Lambdas entirely on your local machine without connecting to a remote cloud provider.

Installation

In this tutorial, we will install LocalStack CLI on our x86-64 Linux machine, for ARM64 kindly check the official documentation. The CLI starts and manages the LocalStack Docker container.

# Download the pre-built binary
curl --output localstack-cli-4.2.0-linux-amd64-onefile.tar.gz \
    --location https://github.com/localstack/localstack-cli/releases/download/v4.2.0/localstack-cli-4.2.0-linux-amd64-onefile.tar.gz

# Extract the LocalStack CLI from the terminal
sudo tar xvzf localstack-cli-4.2.0-linux-*-onefile.tar.gz -C /usr/local/bin

# Verify installed version
localstack --version
4.2.0

Configuring and Starting LocalStack

We need an API key from LocalStack to configure LocalStack on our local machine. Head over to LocalStack and signup. Within your LocalStack dashboard, go to WorkSpace → Auth Tokens and copy the personal auth token provided. This personal auth token will be used to activate the LocalStack pro hobby subscription which grants use access to all of LocalStack’s features such as the Resource Browser which will use in this tutorial. Now add the auth token to your local stack CLI and start LocalStack:

localstack auth set-token 
# By default, LocalStack runs on port 4566. Make sure no service is running on this port otherwise LocalStack won't start
localstack start
