Thin wrapper around the "aws" command line interface for use with LocalStack

Project description

LocalStack AWS CLI

PyPI version

This package provides the awslocal command, which is a thin wrapper around the aws command line interface for use with LocalStack.


You can install the awslocal command via pip:

pip install awscli-local[ver1]

Note that the command above also installs the latest version of the underlying AWS CLI version 1 (awscli) package. Use this command if you prefer to manage your own version of awscli (e.g., v1/v2) and install the wrapper script only:

pip install awscli-local

Note: Automatic installation of AWS CLI version 2 is currently not supported yet (at the time of writing there is no official pypi package for v2 available), but the awslocal technically also works with AWS CLI v2 (see this section for more details).


The awslocal command has the same usage as the aws command. For detailed usage, please refer to the man pages of aws help.


Instead of the following command ...

aws --endpoint-url=http://localhost:4566 kinesis list-streams

... you can simply use this:

awslocal kinesis list-streams


You can use the following environment variables for configuration:

  • LOCALSTACK_HOST: Set the hostname for the localstack instance. Useful when you have localstack is bound to another interface (i.e. docker-machine).
  • USE_SSL: Whether to use https endpoint URLs (required if LocalStack has been started with USE_SSL=true enabled). Defaults to false.
  • DEFAULT_REGION: Set the default region. Overrides AWS_DEFAULT_REGION environment variable.


  • Please note that there is a known limitation for using the cloudformation package ... command with the AWS CLI v2. The problem is that the AWS CLI v2 is not available as a package on, but is instead shipped as a binary package that cannot be easily patched from awslocal. To work around this issue, you have 2 options:

    • Downgrade to the v1 AWS CLI (this is the recommended approach)
    • There is an inofficial way to install AWS CLI v2 from sources. We do not recommend this, but it is technically possible. Also, you should install these libraries in a Python virtualenv, to avoid version clashes with other libraries on your system:
virtualenv .venv
. .venv/bin/activate
pip install

Change Log

  • v0.19: Patch botocore to skip adding data- host prefixes to endpoint URLs
  • v0.18: Pass SYSTEMROOT env variable to fix "_Py_HashRandomization_Init" error on Windows
  • v0.17: Remove obsolete/erroneous FORCE_V2 flag
  • v0.16: Minor fix reading addressing_style in profile config
  • v0.15: Fix lookup of v1/v2 AWS CLI version, apply --s3-endpoint-url only for v1
  • v0.14: Quote file name for windows to allow folder names with spaces
  • v0.13: Fix extra requires for newer pip versions
  • v0.12: Support v1 and v2 of underlying awscli installation
  • v0.9: Add --s3-endpoint-url by default to fix "cloudformation package" command
  • v0.9: Support for DEFAULT_REGION environment variable
  • v0.8: Switch to using edge port for all service endpoints by default
  • v0.7: Apply runtime patch to aws-cli to enable --s3-endpoint-url CloudFormation parameter
  • v0.6: Start aws CLI command in-memory instead of calling external process
  • v0.5: Support piping binary files to stdout; add .bat file for Windows

This package can be replaced by a single bash alias, except for cloudformation package ... as this command requires an additional --s3-endpoint-url parameter:

alias awslocal="AWS_ACCESS_KEY_ID=test AWS_SECRET_ACCESS_KEY=test AWS_DEFAULT_REGION=${DEFAULT_REGION:-$AWS_DEFAULT_REGION} aws --endpoint-url=http://${LOCALSTACK_HOST:-localhost}:4566"
