在docker build中运行docker命令 [英] Running a docker command in docker build
问题描述
我有一个使用docker构建自身的应用程序，我想为其构建docker映像.这需要在 docker build 命令期间将 docker.sock 暴露给应用程序(类似于添加 -v/var/run/run/docker.sock:/var/run/docker.sock 参数传递给 docker run 命令).
I have an application which uses docker to build itself, and I want to build a docker image of it. This requires exposing the docker.sock to the application during the docker build command (similar to adding a -v /var/run/docker.sock:/var/run/docker.sock argument to a docker run command).
有什么方法可以做到这一点，还是应该在虚拟机中构建并将构建工件复制到容器中? Dockerfile 看起来像这样:
It there any way I can do this or should I resort to building in a virtual machine and copying the build artefacts into a container?
The Dockerfile look like this:
FROM docker
RUN docker run --rm -v /opt/<myapp>:/opt/<myapp> <myapp> /build_and_install.sh /opt/<myapp>
# etc...
推荐答案
您的用例尚不清楚.也就是说，在许多情况下，这可以通过多阶段来完成构建.Docker推出了一个Java示例应用程序，其中包含阶段Dockerfile .
Your usecase is a little unclear. That said, in many cases this can be done with a multi-stage build. Docker has put out a sample Java application with a good example of a multi-stage Dockerfile.
