如何将多张图片合二为一? [英] How do I combine several images into one?

我有几个图像(第 3 方)，例如设置 mysql、设置通用 php 应用程序环境、设置第 3 方工具.

## Dockerfile.genericwebapp might have FROM ubuntu
cat Dockerfile.genericwebapp | docker build -t genericwebapp -
## Dockerfile.genericpython-web would have FROM genericwebapp
cat Dockerfile.genericpython-web | docker build -t genericpython-web -
## and then this specific app i'm testing might have a docker file that containers FROM genericpython-web
docker build -t thisapp .

一般来说，在同一个容器上运行多个进程是一种不好的做法.

In general though, it's a bad practice to have more than one running processes on the same container.
