AWS CLI

You can use the AWS CLI to send requests to your mock AWS account by using the --endpoint-url flag followed by the localhost endpoint of your localstack and then any commands. The default localhost port for localstack is 4566.

aws --endpoint-url=http://localhost:4566 <AWS_COMMAND> <ARGUMENTS>

For example, you could create an SNS topic this way using the sns command after the --endpoint-url flag.

aws --endpoint-url=http://localhost:4566 sns create-topic --name my-topic
