Updating LocalStack CLI

The LocalStack CLI allows you to easily update the different components of LocalStack. To check the various options available for updating, run:

$ localstack update --help
Usage: localstack update [OPTIONS] COMMAND [ARGS]...

  Update different LocalStack components.

Options:
  -h, --help  Show this message and exit.

Commands:
  all             Update all LocalStack components
  docker-images   Update docker images LocalStack depends on
  localstack-cli  Update LocalStack CLI

Alternatives

Besides using the CLI, there are other ways of starting and managing your LocalStack instance:

• LocalStack Desktop
  Get a desktop experience and work with your local LocalStack instance via the UI.

• LocalStack Docker Extension
  Use the LocalStack extension for Docker Desktop to work with your LocalStack instance.

• Docker-Compose
  Use Docker Compose to configure and start your LocalStack Docker container.

• Docker
  Use the Docker CLI to manually start the LocalStack Docker container.

• Helm
  Use Helm to create a LocalStack deployment in a Kubernetes cluster.

LocalStack runs inside a Docker container, and the above options are different ways to start and manage the LocalStack Docker container.

The LocalStack emulator is available on Docker Hub in two editions: the Community Edition (localstack/localstack) and the Pro Edition (localstack/localstack-pro).

For a comprehensive overview of the LocalStack images, check out our Docker images documentation.

LocalStack Desktop

Learn more about our desktop client at LocalStack Desktop and download it here.

LocalStack Docker Extension

Install our official Docker Desktop extension to manage LocalStack. See LocalStack Docker Extension for more information.

Docker-Compose

To use LocalStack without the LocalStack CLI, you have the option of running the LocalStack Docker container by yourself. If you want to manually manage your Docker container, it’s usually a good idea to use Docker Compose in order to simplify your container configuration.

Prerequisites

• Docker
• Docker Compose (version 1.9.0+)

Starting LocalStack with Docker-Compose

You can start LocalStack with Docker Compose by configuring a docker-compose.yml file. Docker Compose v1.9.0 and above is supported.

• Community
• Pro

services:
  localstack:
    container_name: "${LOCALSTACK_DOCKER_NAME:-localstack-main}"
    image: localstack/localstack
    ports:
      - "127.0.0.1:4566:4566"            # LocalStack Gateway
      - "127.0.0.1:4510-4559:4510-4559"  # external services port range

      - DEBUG=${DEBUG:-0}
    volumes:
      - "${LOCALSTACK_VOLUME_DIR:-./volume}:/var/lib/localstack"
      - "/var/run/docker.sock:/var/run/docker.sock"

      - LOCALSTACK_AUTH_TOKEN=${LOCALSTACK_AUTH_TOKEN:?}  # required for Pro
      # LocalStack configuration: https://docs.localstack.cloud/references/configuration/
      - DEBUG=${DEBUG:-0}
      - PERSISTENCE=${PERSISTENCE:-0}
    volumes:
      - "${LOCALSTACK_VOLUME_DIR:-./volume}:/var/lib/localstack"
      - "/var/run/docker.sock:/var/run/docker.sock"

Start the container by running the following command:

$ docker-compose up

Please note that there are a few pitfalls when configuring your stack manually via docker-compose (e.g., required container name, Docker network, volume mounts, and environment variables). We recommend using the LocalStack CLI to validate your configuration, which will print warning messages in case it detects any potential misconfigurations:

$ localstack config validate
...

Docker

You can also directly start the LocalStack container using the Docker CLI instead of Docker-Compose. This method requires more manual steps and configuration, but it gives you more control over the container settings.

Prerequisites

Please make sure that you have a working Docker installation on your machine before moving on. You can check if Docker is correctly configured on your machine by executing docker info in your terminal. If it does not report an error (but shows information on your Docker system), you’re good to go.

Starting LocalStack with Docker

You can start the Docker container simply by executing the following docker run command:

• Community
• Pro

$ docker run \
  --rm -it \
  -p 127.0.0.1:4566:4566 \
  -p 127.0.0.1:4510-4559:4510-4559 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  localstack/localstack

$ docker run \
  --rm -it \
  -p 127.0.0.1:4566:4566 \
  -p 127.0.0.1:4510-4559:4510-4559 \
  -p 127.0.0.1:443:443 \
  -e LOCALSTACK_AUTH_TOKEN=${LOCALSTACK_AUTH_TOKEN:?} \
  -v /var/run/docker.sock:/var/run/docker.sock \
  localstack/localstack-pro

Helm

If you want to deploy LocalStack in your Kubernetes cluster, you can use Helm.

Prerequisites

• Kubernetes
• Helm

Deploy LocalStack using Helm

You can deploy LocalStack in a Kubernetes cluster by running these commands:

$ helm repo add localstack-repo https://helm.localstack.cloud
$ helm upgrade --install localstack localstack-repo/localstack

The Helm charts are not maintained in the main repository, but in a separate one.

What’s next?

Now that you have LocalStack up and running, the following resources might be useful for your next steps:

• Check out our Quickstart guide if you are a new user to get started with LocalStack quickly.
• Use the LocalStack integrations to interact with LocalStack and other integrated tools, for example:
  • Use awslocal to use the AWS CLI against your local cloud!
  • Use the Serverless Framework with LocalStack!
  • And many more!
• Find out how to configure LocalStack such that it perfectly fits your need.
• Use LocalStack in your CI environment to increase your code quality.
• Checkout LocalStack’s Cloud Developer Tools to further increase your development efficiency with LocalStack.
• Find out about the ways you can configure LocalStack.

Troubleshooting

The LocalStack CLI installation is successful, but I cannot execute localstack

If you can successfully install LocalStack using pip but you cannot use it in your terminal, you most likely haven’t set up your operating system’s / terminal’s PATH variable (in order to tell them where to find programs installed via pip).

• If you are using Windows, you can enable the PATH configuration when installing Python, as described in the official docs of Python.
• If you are using a MacOS or Linux operating system, please make sure that the PATH is correctly set up - either system wide, or in your terminal.

As a workaround you can call the LocalStack CLI python module directly:

$ python3 -m localstack.cli.main

The localstack CLI does not start the LocalStack container

If you are using the localstack CLI to start LocalStack, but the container is not starting, please check the following:

• Uncheck the Use kernel networking for UDP option in Docker Desktop (Settings → Resources → Network) or follow the steps in our documentation to disable it.
• Start LocalStack with a specific DNS address:

  $ DNS_ADDRESS=0 localstack start

• Remove port 53 as indicated in our standard docker-compose.yml file.

How should I access the LocalStack logs on my local machine?

You can now avail logging output and error reporting using LocalStack logs. To access the logs, run the following command:

$ localstack logs

AWS requests are now logged uniformly in the INFO log level (set by default or when DEBUG=0). The format is:

AWS <service>.<operation> => <http-status> (<error type>)

Requests to HTTP endpoints are logged in a similar way:

2022-09-12T10:39:21.165  INFO --- [   asgi_gw_0] localstack.request.aws     : AWS s3.ListBuckets => 200
2022-09-12T10:39:41.315  INFO --- [   asgi_gw_0] localstack.request.aws     : AWS s3.CreateBucket => 200
2022-09-12T10:40:04.662  INFO --- [   asgi_gw_0] localstack.request.aws     : AWS s3.PutObject => 200
2022-09-12T11:01:55.799  INFO --- [   asgi_gw_0] localstack.request.http    : GET / => 200

How should I share the LocalStack logs for troubleshooting?

You can share the LocalStack logs with us to help us identify issues. To share the logs, call the diagnostic endpoint:

$ curl -s localhost:4566/_localstack/diagnose | gzip -cf > diagnose.json.gz

Ensure that the diagnostic endpoint is run after you have tried reproducing the affected task. After running the task, run the diagnostic endpoint and share the archive file with your team members or LocalStack Support.

My application cannot reach LocalStack over the network

We have extensive network troubleshooting documentation available here.
