在Wordpress Docker容器上未检测到pdo_mysql扩展

Question

我已经使用Docker安装了多个Wordpress网站，特别是Evert Ramos的这个Docker Wordpress Let's Encrypt repo。

尽管可以轻松便捷地部署所需的多个Wordpress安装，但仍然存在一些问题和不足，例如sendmail()函数（然后您必须安装SMTP插件才能解决电子邮件发送问题）。

我发现的主要问题是，安装了此WPvivid插件用于备份Wordpress后，出现以下错误消息：

未检测到pdo_mysql扩展名。 请先安装扩展程序。

我已经用pdo_mysql搜索了如何为Wordpress容器或在Nginx容器内安装pdo_mysql扩展。 但是，我只找到了关于如何安装的答案，但仅针对PHP容器。

Evert Ramos的回购协议不使用任何PHP容器，因此我还没有发现如何或在何处安装该pdo_mysql扩展。

这是我其中一个Wordpress网站docker-compose.yml文件：

    services:
        db_projects:
          container_name: ${CONTAINER_DB_NAME}
          image: mariadb:10.4

关于如何安装该扩展程序的任何想法，或者可以解决该问题的人员？

（我在解决该问题的方法上的有用链接： https : //docs.docker.com/samples/library/wordpress/＆https : //github.com/docker-library/wordpress/blob/c9f1ca12b6fa8181dee161dfc5ce1692eeaef1d1/php7.2/ apache / Dockerfile | https://github.com/docker-library/wordpress/blob/c9f1ca12b6fa8181dee161dfc5ce1692eeaef1d1/php7.3/fpm/Dockerfile ）

按照Anh Tuan的回答，我的dockerfile如下：

您在此堆栈中使用的wordpress映像是Docker Hub的默认映像，并且它们具有有关如何安装新PHP扩展的非常详细的文档。

首先，我们必须在docker-compose.yml文件上进行一些更改，以进行新的wordpress自定义构建：

wordpress:
     depends_on:
       - db
     container_name: ${CONTAINER_WP_NAME}
     # image: wordpress:latest
     build: ./wordpress

其次，在此处创建一个名为Dockerfile和WordPress默认映像的docker-entrypoint.sh的新文件，并将其放在wordpress目录中。 将一些魔术代码修改为wordpress/Dockerfile文件：

RUN docker-php-ext-install pdo pdo_mysql

现在，您有了具有PDO_MYSQL扩展名的自定义Docker堆栈，并能够运行备份过程。

编辑后堆栈的配置： https : //github.com/tdtgit/stackoverflow57447284
