Bootstrap Cache is not shared between the containers

[lukasleitsch]

I ran a Laravel app with this Docker Compose file. One container (web) has the actual app with Autorun enabled. Autorun runs artisan optimize. Only the web container benefits from the bootstrap cache in /var/www/html/bootstrap/cache. The task and horizon containers do not have this cache.

The Health-Checks Package from Spatie runs checks via the scheduler, which runs in the task container. The check fails because that container has no bootstrap cache.

How do you solve this issue? My solution was to add a shared volume for the bootstrap cache folder. (See below)

services:
  web:
    image: my/laravel-app
    environment:
      - HEALTHCHECK_PATH="/up"
      - AUTORUN_ENABLED=true
      - AUTORUN_LARAVEL_MIGRATION_ISOLATION=true
  task:
    image: my/laravel-app
    command: ["php", "/var/www/html/artisan", "schedule:work"]
    stop_signal: SIGTERM
    healthcheck:
      test: ["CMD", "healthcheck-schedule"]
      start_period: 10s
  redis:
    image: redis:6
    command: "redis-server --appendonly yes --requirepass redispassword"
  horizon:
    image: my/laravel-app
    command: ["php", "/var/www/html/artisan", "horizon"]
    stop_signal: SIGTERM
    healthcheck:
      test: ["CMD", "healthcheck-horizon"]
      start_period: 10s

With Bootstrap cache volume:

services:
  web:
    image: my/laravel-app
    environment:
      - HEALTHCHECK_PATH="/up"
      - AUTORUN_ENABLED=true
      - AUTORUN_LARAVEL_MIGRATION_ISOLATION=true
    volumes:
      - ./storage:/var/www/html/storage
      - bootstrap-cache:/var/www/html/bootstrap/cache
  task:
    image: my/laravel-app
    command: ["php", "/var/www/html/artisan", "schedule:work"]
    stop_signal: SIGTERM
    healthcheck:
      test: ["CMD", "healthcheck-schedule"]
      start_period: 10s
    volumes:
      - ./storage:/var/www/html/storage
      - bootstrap-cache:/var/www/html/bootstrap/cache
  redis:
    image: redis:6
    command: "redis-server --appendonly yes --requirepass redispassword"
  horizon:
    image: my/laravel-app
    command: ["php", "/var/www/html/artisan", "horizon"]
    stop_signal: SIGTERM
    healthcheck:
      test: ["CMD", "healthcheck-horizon"]
      start_period: 10s
    volumes:
      - ./storage:/var/www/html/storage
      - bootstrap-cache:/var/www/html/bootstrap/cache

volumes:
