docker 容器中未指定应用程序加密密钥

【中文标题】docker 容器中未指定应用程序加密密钥

【英文标题】：No application encryption key has been specified in docker container

【问题描述】：

我想开始使用 docker。我已经启动了 nginx、laravel 和 mysql 容器。但是我有问题，当我想访问我的页面时，我得到：

No application encryption key has been specified

在我在 cointainer 中的 env 文件中，我有 APP_KEY=base64:isqaS8uLDmiO47hZLTTKmheHM13uBkeA6wTWG1nF5E4= 由命令 php artisan key:generate 生成，我得到了 Application key set successfully.。

当我检查php artisan tinker 值env('APP_KEY') 时，我只得到""。更重要的是，我发现当.env 文件中没有APP_KEY 部分时，此命令不起作用。

对 env 文件的权限如下所示： -rwxr-xr-x 1 www-data www-data 829 Sep 17 12:22 .env

来自日志文件的错误

我尝试重新启动服务器，清除缓存并删除和添加新密钥，但这没有帮助。

编辑： 这是我的 dockerfile

FROM php:7.4.0-fpm

COPY composer.lock composer.json /var/www/

COPY database /var/www/database

WORKDIR /var/www

RUN apt-get update && apt-get -y install git && apt-get -y install zip

RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

【问题讨论】：

请添加您的 dockerfile

抱歉，我忘记了。添加到编辑部分。

【参考方案1】：

问题可能来自 .env.prod 的使用。

在这种情况下，.env.prod 将被 Docker 加载到 OS 容器 env 变量中。

而Dotnet主要使用操作系统的环境变量。

为了确定，请尝试在 .env.prod 中设置 APP_KEY 值并重新启动 docker ：docker-compose restart
