Reproductions

[BUG?] Multiple containers launched for same lambda

To reproduce a case where many containers are launched to process the same lambda code (which is problematic for attempting to attach a debugger):

# Bring up localstack
$ docker compose up -d

# Install Localstack CLI (creates a python virtualenv and installs localstack + awscli-local)
$ bin/install-tools

# Build and deploy the lambdas
$ yarn install
$ yarn deploy

# Invoke the same lambda multiple times in-parallel, which triggers this behavior
$ for i in {1..10}; do echo $i; done | xargs -I{} -P 10 bin/lambda-invoke echo {}

# Check to see that multiple instances of the lambda have launched
$ docker ps --filter name=localstack-sample-echo
