Yii2 Queue with Redis on Docker Swarm is a game changer

I don't know why I haven't utilized this before, but the yiisoft/yii2-queue is a fantastic way to quickly and easily split some of your application processing out to asynchronous workers.

Getting it set up with a redis storage engine on a docker stack is super simple -- we just add a persistent redis service to the docker stack, configure the application to include the queue component, and move our slow process(es) into a queue job.

Since we're using a Docker Swarm stack we don't need to worry about setting up a cron or systemd service, we set up the queue listener as it's own service in the stack, which also gives us the ability to scale the queue workers dynamically as the need arises.
