Docker + Laravel queue:work
The queue:work command runs in the foreground, so you should run it that way so the container doesn't exit immediately.
Since the application code in Laravel is the same for running a container as a web application, queue, or scheduler I build one image that I can use in these contexts. I use a bash start script with an environment variable to define a container role, and this is what I run for a queue worker container:
#!/bin/bash# Defaults to an app serverrole=${CONTAINER_ROLE:-app}if [ "$role" = "queue" ]; then # Run queue php artisan queue:work --verbose --tries=3 --timeout=90elif [ "$role" = "app" ]; then # Run the web application /usr/bin/caddy --agree=true --conf=/etc/Caddyfileelif [ "$role" = "scheduler" ]; then while [ true ] do php artisan schedule:run --verbose --no-interaction & sleep 60 doneelse echo "Could not match the container role...." exit 1fi
Also note the infinite while loop and sleep combo to keep the scheduler role running and running the schedule:run command in the background in case the scheduler runs overlap (since they need to run every minute regardless of if the last one finished).
You can't run the queue in the background, otherwise the container stops, as the command has effectively finished. Remove the &
and it will stay alive.
However, you can do something like tail -f /dev/null
as the final command to keep the container running if you want to run the queue in the background and still be able to attach to the container and access the shell.
If you need graceful shutdown for queue, you can follow this.
This is taken from @Paul Redmond's article at Laravel News and extending his docker-entrypoint file so suite my need. After a lot of testing for graceful shutdown I finally was able to do.
First thing in docker-compose.yml file set stop_signal: SIGTERM
for your queue service.
queue: image: laravel-www container_name: laravel-queue stop_signal: SIGTERM depends_on: - app volumes: - .:/var/www/html ...
Next in the entrypoint.sh file, the main thing is to run the queue:work using the exec
command.
#!/usr/bin/env bashset -e# Run our defined exec if args emptyif [ -z "$1" ]; then role=${CONTAINER_ROLE:-app} env=${APP_ENV:-production} if [ "$env" != "local" ]; then echo "Caching configuration..." (cd /var/www/html && php artisan cache:clear && php artisan config:clear && php artisan route:clear && php artisan view:clear) (cd /var/www/html && php artisan config:cache && php artisan event:cache && php artisan route:cache && php artisan view:cache) fi if [ "$role" = "app" ]; then echo "Running PHP-FPM..." exec php-fpm elif [ "$role" = "queue" ]; then echo "Running the queue..." exec php /var/www/html/artisan queue:work -vv --no-interaction --tries=3 --sleep=5 --timeout=300 --delay=10 elif [ "$role" = "cron" ]; then echo "Running the cron..." while [ true ] do exec php /var/www/html/artisan schedule:run -vv --no-interaction sleep 60 done else echo "Could not match the container role \"$role\"" exit 1 fielse exec "$@"fi
Your are done. Next time you stop queue service, it will stop gracefully and won't wait 10 seconds for SIGKILL
. I think it has to do with the PID 1
thing.
