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.

Installation

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).

Usage

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

Example

Instead of the following command ...

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

... you can simply use this:

awslocal kinesis list-streams

Configurations

You can use the following environment variables for configuration:

  • AWS_ENDPOINT_URL: The endpoint URL to connect to (takes precedence over USE_SSL/LOCALSTACK_HOST below). Useful when you have LocalStack bound to a different host (e.g., within docker-compose).
  • LOCALSTACK_HOST (deprecated): A : variable defining where to find LocalStack (default: localhost:4566).
  • USE_SSL (deprecated): Whether to use SSL when connecting to LocalStack (default: False).

Completion

awscli provides a neat command completion feature which is compatible with most modern shells which can also be used with awslocal.

Usage instructions

The command completion will automatically suggest commands and parameters when using the completion key (which is typically the Tab key):

$ awslocal dynamodb d<TAB>
delete-backup                        describe-global-table
delete-item                          describe-global-table-settings
delete-table                         describe-limits
describe-backup                      describe-table
describe-continuous-backups          describe-table-replica-auto-scaling
describe-contributor-insights        describe-time-to-live
describe-endpoints

Configuration

  • Follow the official guide on setting up the command completion for the aws CLI: https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-completion.html

  • While enabling the command completion for your shell, make sure to register the completion for awslocal as well.

    For example, if you are using bash, you would add the following commands to your ~/.bashrc:

    complete -C '/usr/local/bin/aws_completer' aws
    complete -C '/usr/local/bin/aws_completer' awslocal
  • Follow the instructions for the shell you are using. For some shells you might need to register a different command or enable certain compatibility plugins (like zsh).

Limitations

  • Please note that there is a known limitation for using the cloudformation package ... command with the AWS CLI v2. Currently it is not possible to specify the S3 endpoint URL, and this issue is not yet resolved on AWS side. The problem is that the AWS CLI v2 is not available as a package on pypi.org, 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 https://github.com/boto/botocore/archive/v2.zip https://github.com/aws/aws-cli/archive/v2.zip

Change Log

  • v0.22.0: Use fallback for endpoint detection. Should prevent most cases of Unable to find LocalStack endpoint for service ...
  • v0.21.1: Introducing semantic versioning and list of services without endpoints
  • v0.21: Use placeholder credentials and region only if Boto cannot not find them, fix output streaming for logs tail call
  • v0.20: Small fixes for Python 2.x backward compatibility
  • 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
  • v0.4: Minor fix for Python 3 compatibility
  • v0.3: Add support for additional service endpoints
  • v0.2: Enable SSL connections; refactor code
  • v0.1: Initial release

Alternative

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"
