Docker - 环境变量不会覆盖php.ini

我在docker上运行自定义php应用程序。 我已经设置了一些用于配置php.ini或apache的env变量但是当我执行 docker-compose up --build </ code>并尝试从浏览器访问应用程序(index.php)时我可以 看到env变量没有覆盖php.ini文件或apache conf。 我有什么想法吗?</ p>

这些是我的文件</ p>

docker-compose.yml </ p>

  services:
app:
container_name:myapp
build:
上下文:。
dockerfile:docker / Dockerfile
卷:
  • 。:/ var / www / html ports:
  • 8080:80 env_file:
  • ./.env networks:
  • .netnet
    </ code> </ pre>

    Dockerfile </ p>

I'm having a custom php app running on docker. I have set up some env variables for configuring the php.ini or the apache but when I do docker-compose up --build and try to access the app (index.php) from the browser I can see the env variables have not overwritting the php.ini file or the apache conf. Any ideas what I'm doing wrong?

These are my files

docker-compose.yml

services:
    app:
        container_name: myapp
        build:
            context: .
            dockerfile: docker/Dockerfile
        volumes:
            - .:/var/www/html
        ports:
            - 8080:80
        env_file:
            - ./.env
        networks:
            - appnet

Dockerfile

FROM php:7.3-apache-stretch
COPY docker/vhost.conf /etc/apache2/sites-available/000-default.conf
COPY docker/config/php/php.ini /usr/local/etc/php/php.ini
COPY docker/config/php/conf.d/*.ini /usr/local/etc/php/conf.d/
COPY . /var/www/html/
WORKDIR /var/www/html/

php.ini

date.timezone = ${PHP_DATE_TIMEZONE}
display_errors = ${PHP_DISPLAY_ERRORS}
error_reporting = ${PHP_ERROR_REPORTING}

.env

PHP_DATE_TIMEZONE = Europe/London
PHP_DISPLAY_ERRORS = 1
PHP_ERROR_REPORTING = -1

index.php

问题是 .env </ code>文件中有空格。</ p>

< p>尝试将其更改为:</ p>

  PHP_DATE_TIMEZONE = Europe / London 
PHP_DISPLAY_ERRORS = 1
PHP_ERROR_REPORTING = -1
</ code> </ pre>


Compose期望env文件中的每一行都是VAR = VAL格式。</ p>
</ blockquote>

The issue is you have spaces in your .env file.

Try changing it to:

PHP_DATE_TIMEZONE=Europe/London
PHP_DISPLAY_ERRORS=1
PHP_ERROR_REPORTING=-1

Compose expects each line in an env file to be in VAR=VAL format.
