Current Behavior

I'm using the following code to start localstack in Github Actions. Since upgrading to latest my loop checking for \"dynamodb\": \"running\" never resolves and it hangs forever.

docker-compose.yml

version: '2.1'

services:
  localstack:
    container_name: '${LOCALSTACK_DOCKER_NAME-localstack_main}'
    image: localstack/localstack:latest
    network_mode: bridge
    ports:
      - '4566:4566'
      - '4571:4571'
    environment:
      - SERVICES=${SERVICES- }
      - DEBUG=${DEBUG- }
      - DATA_DIR=${DATA_DIR- }
      - DOCKER_HOST=unix:///var/run/docker.sock
      - HOST_TMP_FOLDER=${TMPDIR}

start-localstack.sh

# start in detached/background mode
SERVICES=dynamodb,sns docker-compose -f $DIR/docker-compose.yml up -d

#!/bin/bash
echo "waiting for dynamodb at ${AWS_ENDPOINT}/health"

# ping the localstack /health endpoint until it shows dynamo is running
until (curl --silent ${AWS_ENDPOINT}/health | grep "\"dynamodb\": \"running\"" > /dev/null); do
  printf '.'
  sleep 5
done

Expected Behavior

Once started /health response should contain \"dynamodb\": \"running\"

How are you starting LocalStack?

With a docker-compose file
