如何为开发和生产配置不同的 dockerfile [英] How to configure different dockerfile for development and production

问题描述

我使用 docker 进行 laravel 项目的开发和生产.对于开发和生产，我的 dockerfile 略有不同.例如，我在开发环境中将本地目录挂载到 docker 容器，这样我就不需要为代码的每次更改都进行 docker build.

I use docker for development and in production for laravel project. I have slightly different dockerfile for development and production. For example I am mounting local directory to docker container in development environment so that I don't need to do docker build for every change in code.

由于挂载的目录只有在运行 docker 容器时才可用，所以我不能在 dockerfile 中放置composer install"或npm install"等命令进行开发.

As mounted directory will only be available when running the docker container I can't put commands like "composer install" or "npm install" in dockerfile for development.

目前我正在管理两个 docker 文件，有什么方法可以使用单个 docker 文件执行此操作，并通过发送参数来决定在执行 docker build 时运行哪些命令.

Currently I am managing two docker files, is there any way that I can do this with single docker file and decide which commands to run when doing docker build by sending parameters.

我想要实现的是

在 docker 文件中

...
IF PROD THEN RUN composer install
...

在 docker 构建期间

docker build [PROD] -t mytag .

推荐答案

更新(2020):自从这是 3 年前写的，很多事情都发生了变化(包括我对这个话题的看法).我建议的方法是使用 one dockerfile 并使用脚本.请参阅 @yamenk 的回答.

UPDATE (2020): Since this was written 3 years ago, many things have changed (including my opinion about this topic). My suggested way of doing this, is using one dockerfile and using scripts. Please see @yamenk's answer.

原文:

您可以使用两个不同的 Dockerfile.

You can use two different Dockerfiles.

# ./Dockerfile (non production)
FROM foo/bar
MAINTAINER ...

# ....

还有第二个:

# ./Dockerfile.production
FROM foo/bar
MAINTAINER ...

RUN composer install

在调用构建命令时，您可以知道它应该使用哪个文件:

While calling the build command, you can tell which file it should use:

$> docker build -t mytag .
$> docker build -t mytag-production -f Dockerfile.production .
