    # - WORDPRESS_DB_USER=__WORDPRESS_DB_USER__

  ports:
    - "9888:80"

mysql:

问题详情

我能够将 composer.json 和 composer.lock 文件ADD 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(或任何地方)也自动将依赖项安装到工作目录中.

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，但是如何在 Dockerfile 中执行此操作?

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挂载到容器中有关，但我已经 ADDed 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.

感谢您的帮助.

推荐答案

您只需在运行 composer 容器时将当前目录挂载到 /app 即可.我在 https://gist.github.com/andyshinn/整理了一个简单的例子来说明这个工作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'(应用程序可能在 Composer 运行之前不会运行，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).
