Docker撰写文件

wordpress:
  build: .
  links:
    - mysql
    - composer
  volumes:
    - wp-content/plugins/:/var/www/html/wp-content/plugins
    - wp-content/themes/:/var/www/html/wp-content/themes
  environment:
    - WORDPRESS_DB_PASSWORD=__WORDPRESS_DB_PASSWORD__
    - WORDPRESS_DB_NAME=__WORDPRESS_DB_NAME__
    # - WORDPRESS_DB_USER=__WORDPRESS_DB_USER__

  ports:
    - "9888:80"

mysql:
  image: mysql:5.7
  environment:
    - MYSQL_ROOT_PASSWORD=__WORDPRESS_DB_PASSWORD__
    - MYSQL_DATABASE=__WORDPRESS_DB_NAME__

composer:
  image: composer/composer

问题详细信息

我能够 ADD composer.json 和 composer.lock 文件到工作目录.我可以确认这两个文件在工作目录中.

Question details

I'm able to ADD the composer.json and composer.lock files to the working directory. I can confirm that these two files are in the working directory.

我需要的是Dockerfile(或其他位置)也将依赖项自动安装到工作目录中.

What I need is for the Dockerfile (or wherever) to also automatically install the dependencies into the working directory.

根据Docker Hub， https://hub.docker.com/r/composer/作曲家/，我应该能够 docker run -v $ {pwd):/app composer/composer install 来安装依赖项，但是我该如何在Dockerfile中做到这一点呢?

According to Docker Hub, https://hub.docker.com/r/composer/composer/, I should be able to docker run -v $(pwd):/app composer/composer install to install the dependencies but how do I do this in Dockerfile?

我也很困惑，因为 -v 标志 https://docs.docker.com/engine/userguide/dockervolumes/与将指定的主机目录装入容器有关，但是我已经 ADD 了必要的文件到工作目录.我要做的就是安装依赖项.

Also I'm confused because the -v flag, https://docs.docker.com/engine/userguide/dockervolumes/, has to do with mounting the specified host directory into the a container but I've already ADDed the necessary files to the working directory. All I want to do is install the dependencies.

谢谢您的帮助.

推荐答案

运行 composer 容器时，只需要将当前目录挂载到/app .我在 https://gist.github.com/andyshinn/处放了一个简单的示例来说明此工作e2c428f2cd234b718239 .

You just need to mount the current directory to /app when running your composer container. I've put together a simple example to illustrate this working at https://gist.github.com/andyshinn/e2c428f2cd234b718239.

这里的关键部分是应用程序 composer 部分的 volumes 和主要PHP应用程序上的 restart:'yes'(在Composer运行之前，该应用程序可能无法运行，因此您希望它重新启动.)

The key parts here are the volumes for the composer part of the application and the restart: 'yes' on the primary PHP application (the application likely will not run until Composer has run so you will want it to restart).
