How to tell aws-cli to use localstack?

Specify endpoint-url in the commands

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

// S3
// list buckets
aws --endpoint-url=http://localhost:4566 s3 ls
// make buckets
aws --endpoint-url=http://localhost:4566 s3 mb s3://bucket1
aws --endpoint-url=http://localhost:4566 s3 mb s3://bucket2

aws --endpoint-url=http://localhost:4566 s3 delete-bucket --bucket loremipsum.txt

// DynamoDB
aws --endpoint-url=http://localhost:4566 dynamodb list-tables

awslocal

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

https://github.com/localstack/awscli-local

awslocal dynamodb list-tables

With this, instead of the following command aws --endpoint-url=http://localhost:4566 kinesis list-streams, you can simply use this: awslocal kinesis list-streams

If you would rather just use the aws commands, you don’t have to install awslocal. Just make sure to specify the endpoint url in the aws commands.

Stopping it

localstack stop
