Automatically create SQS queue using localstack and docker-compose

Is there any way to automatically create SQS Queus using localstack with docker-compose.yml?

My docker-compose.yml:

version: '3.8'
services:
  localstack:
    image: localstack/localstack
    ports:
      - "4566:4566"
      - "4571:4571"
      - "${PORT_WEB_UI-8080}:${PORT_WEB_UI-8080}"
    environment:
      - SERVICES=${SERVICES- }
      - DEBUG=${DEBUG- }
      - DATA_DIR=${DATA_DIR- }
      - PORT_WEB_UI=${PORT_WEB_UI- }
      - LAMBDA_EXECUTOR=${LAMBDA_EXECUTOR- }
      - KINESIS_ERROR_PROBABILITY=${KINESIS_ERROR_PROBABILITY- }
      - DOCKER_HOST=unix:///var/run/docker.sock
    volumes:
      - "${TMPDIR:-/tmp/localstack}:/tmp/localstack"

I would like to have some queues created when start docker-compose instead of create it manually.

If you want to automatically bootstrap all needed queues on docker up, you can add a shell script that will be run by localstack on docker container start.

Here is an example.

Add to your volumes the following:

- ./localstack_bootstrap:/docker-entrypoint-initaws.d/

Then add to the directory specified above (localstack_bootstrap in my case) a shell script with any name you like (I decided to call it sqs_bootstrap.sh) with the following contents:

#!/usr/bin/env bash

set -euo pipefail

# enable debug
# set -x

echo "configuring sqs"
echo "==================="
LOCALSTACK_HOST=localhost
AWS_REGION=eu-central-1

create_queue() {
    local QUEUE_NAME_TO_CREATE=$1
    awslocal --endpoint-url=http://${LOCALSTACK_HOST}:4566 sqs create-queue --queue-name ${QUEUE_NAME_TO_CREATE} --region ${AWS_REGION} --attributes VisibilityTimeout=30
}

create_queue "queue1"
create_queue "queue2"

Don't forget to run chmod +x ./localstack_bootstrap/sqs_bootstrap.sh.

Localstack currently does not have anything to do this automatically at start-up. For now I suggest either:

  • create a script that starts docker-compose and calls the aws cli tool to create the topic you need. This needs a sleep in the script :(
  • Build an image based on localstack that has an extra startup start with your additional setup stuff
