docker⼆进制代码编译Contentsdocker如何编译，在 进⾏了介绍。其实很简单，就是在docker源码中有⼀个makefile⽂件，执⾏make，就可以进⾏编译了。我们从源码来看⼀下make的过程。⾸先看⼀下Makefile。...DOCKER_MOUNT := $(if $(BINDDIR),-v "$(CURDIR)/$(BINDDIR):/go/src//docker/docker/$(BINDDIR)")DOCKER_RUN_DOCKER := docker run --rm -it --privileged -e TIMEOUT -e BUILDFLAGS -e TESTFLAGS -e TESTDIRS -e DOCKER_GRAPHDRIVER -e DOCKER_EXECDRIVER $(DOCKER_MOUNT) "$(DOCKER_IMAGE)"...binary: build $(DOCKER_RUN_DOCKER) hack/ build: bundlesdocker build -t "$(DOCKER_IMAGE)" ....bundles: mkdir bundles执⾏make binary。会⾸先创建bundles⽂件夹，然后执⾏docker build，通过dockerfile创建镜像（这⼀步其实可以直接从官⽹pull镜像⽽不⽤⾃⼰build，下⾯详细讲）。然后将容器run起来，通过-v参数，将容器中的bundles同物理机的该路径下的bundles⽂件夹绑定起来，然后启动容器。容器执⾏了hack/dind命令，编译docker，将编译好的⽂件放在了bundles中。从⽽在物理机上也可见。对于docker的⼆进制代码编译采取了⼀种极为dockerful的⽅式。因为搭建docker的编译环境可能会较为繁琐，docker直接提供给了⼀个 的镜像给⽤户。获得这个镜像有两种⽅式，⼀种是直接下载。⽤户只需要下载这个镜像，就可以在这个镜像中进⾏docker的⼆进制代码的编译了。另⼀种，就是使⽤Dockerfile进⾏进⾏build，来获取镜像。Dockerfile⽂件就在docker源码的根⽬录下。这种⽅式⽐较耗时，不推荐。有了docker-dev镜像，其实不必每次都要docker build镜像，⽽只需要利⽤原有镜像就可以了。那么我修改了Makefile⽂件，从⽽可以⽀持能够使⽤docker-dev镜像进⾏编译。更新后的Makefile在末尾附带。在我的⾥⾯⽀持了多种⽅式来灵活使⽤本地环境：通过build⽅式make DOCKER_COMMAND=build通过pull⽅式（默认，pull与本版本相同的docker-dev镜像）make通过pull⽅式，指定本地镜像（不再pull镜像）make DOCKER_IMAGE=docker-dev:v1.2另外⼀种⽅法，就是把你的代码上传到github上。这种⽅式真⼼慢，没个半⼩时弄不出来（实测是20min），虽然是官⽅推荐。但是我感觉这更像是给他们⾃⼰做的⼀种硬⼴告。。。.PHONY: all binary build cross default docs docs-build docs-shell shell test test-unit test-integration test-integration-cli test-docker-py validate# env vars passed through directly to Docker's build scripts# to allow things like `make DOCKER_CLIENTONLY=1 binary` easily# `docs/sources/contributing/ ` and `project/` have some limited documentation of some of theseDOCKER_ENVS := -e BUILDFLAGS -e BUILDFLAGS -e DOCKER_CLIENTONLY -e DOCKER_EXECDRIVER -e DOCKER_GRAPHDRIVER -e TESTDIRS -e TESTFLAGS -e TIMEOUT# note: we _cannot_ add "-e DOCKER_BUILDTAGS" here because even if it's unset in the shell, that would shadow the "ENV DOCKER_BUILDTAGS"
