docker 1.8.2 源代码编译

编译docker的必要条件

  这阵子在公司搞docker container这些技术,docker编译网上查了一下木有靠谱的。只好自己动手丰衣足食了。

  声明:你编译docker不需要git pull它的源码,必备条件只有一个,就是你有一台能pull镜像的docker主机就行了。

本人环境是VMware下CentOS Linux release 7.1.1503 (Core) [x86_64]

以下为编译过程的具体记录

 

1.pull docker-dev:1.8.2的镜像

[root@myserv docker]# docker pull docker-dev:1.8.2

2.创建一个目录存放docker编译后生成的文件夹

[root@myserv home]# mkdir -p /home/dockerbuild/bundles
[root@myserv home]# cd /home/dockerbuild/

3.运行刚刚pull好的docker-dev镜像,然后在容器里进行docker的编译工作

[root@myserv home]# docker run --rm -it --privileged \
  -e BUILDFLAGS -e DOCKER_CLIENTONLY -e DOCKER_EXECDRIVER -e DOCKER_EXPERIMENTAL \
  -e DOCKER_GRAPHDRIVER -e DOCKER_STORAGE_OPTS -e DOCKER_USERLANDPROXY -e TESTDIRS -e TESTFLAGS -e TIMEOUT \
  -v /home/dockerbuild/bundles:/go/src/github.com/docker/docker/bundles docker-dev:1.8.2 bash
  
root@87193e358c88:/go/src/github.com/docker/docker# hack/make.sh binary

---> Making bundle: binary (in bundles/1.8.2/binary)
Building: bundles/1.8.2/binary/docker-1.8.2
Created binary: bundles/1.8.2/binary/docker-1.8.2

4.查看编译输出并验证编译结果

root@87193e358c88:/go/src/github.com/docker/docker# ls -l bundles/1.8.2/binary/
total 21104
lrwxrwxrwx 1 root root       12 Sep 15 10:20 docker -> docker-1.8.2
-rwxr-xr-x 1 root root 21599668 Sep 15 10:20 docker-1.8.2
-rw-r--r-- 1 root root       47 Sep 15 10:20 docker-1.8.2.md5
-rw-r--r-- 1 root root       79 Sep 15 10:20 docker-1.8.2.sha256

  上述可以看到在容器内,bundles目录已经有了编译好的docker程序文件了。退出容器后,在本机/home/dockerbuild/bundles/1.8.2/binary目录下会得到一个编译完毕的docker。

[root@myserv dockerbuild]# cd bundles/
[root@myserv bundles]# ls
1.8.2  latest
[root@myserv bundles]# cd 1.8.2/
[root@myserv 1.8.2]# ls
binary
[root@myserv binary]# ls -l
total 21104
lrwxrwxrwx 1 root root       12 Sep 15 18:20 docker -> docker-1.8.2
-rwxr-xr-x 1 root root 21599668 Sep 15 18:20 docker-1.8.2
-rw-r--r-- 1 root root       47 Sep 15 18:20 docker-1.8.2.md5
-rw-r--r-- 1 root root       79 Sep 15 18:20 docker-1.8.2.sha256
[root@myserv binary]# ./docker version

题外话

  官方之所以选择在容器内编译docker的方式是因为容器内部已经集成好编译docker所需的环境及组件了,我也懒得在centos里将依赖一个个装了。

 

本文到此结束,谢谢。
