如何在 docker 的官方 php-fpm-alpine 镜像上安装 XDebug? [英] How do I install XDebug on docker's official php-fpm-alpine image?

问题描述

我正在使用基于 php:7.1-fpm-alpine (https://github.com/docker-library/wordpress/blob/master/php7.1/fpm-alpine/Dockerfile).

I'm using wordpress:php7.1-fpm-alpine which is based on php:7.1-fpm-alpine (https://github.com/docker-library/wordpress/blob/master/php7.1/fpm-alpine/Dockerfile).

我试过 RUN pecl install xdebug-2.5.0 &&docker-php-ext-enable xdebug

导致构建时出错:

Step 19/19 : RUN pecl install xdebug-2.5.0     && docker-php-ext-enable xdebug
 ---> Running in 52c988e12cb2

推荐答案

以下内容足以在该图像上简单地安装 xdebug:

The following is sufficient for simply installing xdebug on that image:

FROM wordpress:php7.1-fpm-alpine

RUN apk add --no-cache $PHPIZE_DEPS 
    && pecl install xdebug-2.5.0 
    && docker-php-ext-enable xdebug

构建它然后从结果图像中的 shell 运行会产生以下结果:

Building that and then running from a shell inside the resulting image produces the following:

$ php -i | grep Xdebug
