While testing a Laravel app running on AWS Elastic Beanstalk I came across the situation where I wanted to be able to test how my app would handle interacting with the worker tier SQS daemon (sqsd) on my local machine. As sqsd is not open source there is currently no official way of doing this.

This project (inspired by others) is an attempt to replicate the functionality of sqsd in PHP for local testing purposes. Note that his library has no dependency on Laravel and can be used to test any kind of app.


Sqsd architecture

The Laravel queue worker operates by polling a queue for jobs and then runs them inline (as the queue worker is part of the application). As sqsd is completely separate from any application it works in a different way so that any application can be designed to work with it.

Sqsd works by polling a SQS queue for jobs and then POST's them to an endpoint specified in your Elastic Beanstalk worker environment settings (default is http://localhost/). If a job fails for any reason, then the job is sent to what is called a Dead Letter Queue for manual processing.

Another aspect of sqsd is that it can read a cron.yaml file in the root of your application which specifies periodic tasks that can be run on a schedule. Sqsd will send a job to the queue every time the schedule is triggered. These jobs will then be processed by sqsd like normal, but will be POSTed to the path specified in the cron.yaml with some extra headers.


  • PHP >= 5.5.0
  • Composer

Install & Usage

  1. Clone this repo
  2. Copy .env.example to .env and fill in the details (see below)
  3. Run composer install
  4. Run php ./bin/sqsd.phar work

To install as a composer dependency:

  1. Run composer require gilbitron/sqsd
  2. Run php ./vendor/bin/sqsd.phar work

Note: If your're running sqsd as a composer dependency you will need to set your environment variables via the command line (see below for more info).


Configuration is done by either setting environment variables before running sqsd (e.g. export SQS_QUEUE_URL=https://sqs.us-east-1.amazonaws.com/123456789) or specifying them in .env.

Env Variable Description
AWS_ACCESS_KEY_ID * AWS access key ID with SQS permissions
AWS_SECRET_ACCESS_KEY * AWS secret access key
SQS_QUEUE_URL * The URL of the SQS queue (e.g. https://sqs.us-east-1.amazonaws.com/123456789)
SQS_QUEUE_NAME * The name of the SQS queue
SQS_QUEUE_REGION * The region of the SQS queue (e.g. us-east-1)
SQS_MAX_MESSAGES The maximum number of messages that will be received from the SQS queue at a time (default and max is 10)
SQS_WAIT_TIME The length of time in seconds that sqsd will wait while polling the SQS queue for messages
SQSD_WORKER_URL The URL the worker will POST to (default is http://localhost)
SQSD_WORKER_PATH The path that will be appended to the worker URL (default is /). This is the same as the HTTP Path setting in the Elastic Beanstalk worker environment settings
SQSD_CRON_PATH Absolute path to a cron.yaml which specifies periodic tasks
SQSD_SLEEP_SECONDS The time in seconds sqsd should sleep between checks (default is 1)
SQSD_STORAGE_PATH Path to a writable storage dir (default is /tmp/sqsd)

Environment variables marked with a * are required for sqsd to work.

Building the Phar

To build Phar file first you need to install Box then run:

box build -v

Laravel Tips

If you're looking for a package that will make Laravel work with sqsd I recommend dusterio/laravel-aws-worker.

If you are using this to test a Laravel app, instead of configuring Supervisor to run the aritsan queue:work command, configure Supervisor to run the sqsd work command.
