Question

我无法刷新Laravel缓存，我认为问题可能与使用多个运行Laravel堆栈的Docker容器有关。我已经尝试过php artisan cache:clear和php artisan config:cache。我已经删除了bootstrap/cache/config.php，但该文件只是以旧配置重新出现，就像一些不死生物在困扰着我。

我能够刷新缓存的唯一方法是使用docker-compose down完全删除容器，然后再次运行容器。

在下面的docker-compose中，您可以看到我的应用程序，队列和调度程序容器都运行Laravel堆栈，并从主机安装了代码库。这会导致问题吗？

docker-compose.yml

有人可以告诉我如何在不破坏容器的情况下重新加载缓存吗？

为了完整起见，我使用以下指南设置了Docker环境：https://www.digitalocean.com/community/tutorials/how-to-set-up-laravel-nginx-and-mysql-with-docker-compose

我正在使用以下指南运行队列和调度程序容器：https://laravel-news.com/laravel-scheduler-queue-docker。但是，我已经修改了队列以运行Supervisor。

start.sh

#!/usr/bin/env bash

set -e

role=${CONTAINER_ROLE:-app}
env=${APP_ENV:-production}

if [ "$env" != "local" ]; then
    echo "Caching configuration..."
    (php artisan config:cache && php artisan view:cache) # && php artisan route:cache - can't cache route closures
fi

if [ "$role" = "app" ]; then

    exec php-fpm

elif [ "$role" = "queue" ]; then

    echo "Running the queue..."
    /usr/bin/supervisord

elif [ "$role" = "scheduler" ]; then

    while [ true ]
    do
      php artisan schedule:run --verbose --no-interaction &
      sleep 60
    done

else
    echo "Could not match the container role \"$role\""
    exit 1
fi

我思考现在，我了解发生了什么事。我的Laravel配置选项由.env文件定义，我的docker-compose.yml文件也正在读取该文件来设置容器环境变量。这些container environment variables cannot be changed at runtime总是优先于容器运行时对.env文件所做的更改。

停止和启动容器不会更改环境变量。只有破坏容器并使其重新启动，然后重新读取.env文件以设置环境变量，我的更改才会生效。

那么正确的设置应该是仅将.env用于Laravel，并将一个单独的文件用于容器环境变量。换句话说，更改env_file: '.env'中的docker-compose.yml条目。
