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
[[email protected] docker]# docker pull docker-dev:1.8.2 Pulling repository docker-dev ab03141ac2e9: Pulling dependent layers d3a1f33e8a5a: Download complete c22013c84729: Download complete d74508fb6632: Download complete 91e54dfb1179: Download complete 758970a22420: Download complete 62fd5b9e4d35: Download complete 944fcdea21b1: Download complete ab975b7812f0: Download complete 0f860819eb9c: Download complete adcf22790962: Download complete c79325ee5872: Download complete 115d2806e84a: Download complete 1705282a2f45: Download complete 5d8bf41b5802: Download complete 3388f79cde5c: Download complete 979009c412cd: Download complete 11eaa2b57f9e: Download complete b3ff0a3e16f1: Download complete a7cc3d81aeed: Download complete 94b8248ce242: Download complete 006aa3cb8d92: Download complete 5ce85bb004d1: Download complete 28907ad32b10: Download complete 919096bcd935: Download complete 2a138d63ee40: Download complete 2b2733893e80: Download complete ab03141ac2e9: Download complete 906727032fc8: Download complete c296523a5eea: Download complete f38d4f3bc631: Download complete b5564cf04aab: Download complete cd3a9bdbad49: Download complete a223a267d4b0: Download complete 0912427504fa: Download complete 9d153769f49b: Download complete 4ec1b8c4c270: Download complete 7ca719ee5f14: Download complete 3b994c4a49de: Download complete 062d730e6007: Download complete ac1892714a82: Download complete ac43d240b0a2: Download complete dbab3fbdd774: Download complete 79d657b6d894: Download complete 725fa96f33ab: Download complete ad50f4526814: Download complete ee0aa2630de6: Download complete a9314782dbbf: Download complete 23f7502170cd: Download complete 8bfc29dd7728: Download complete Status: Downloaded newer image for docker-dev:1.8.2
2.创建一个目录存放docker编译后生成的文件
[[email protected] home]# mkdir -p /home/dockerbuild/bundles [[email protected] 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
[[email protected] 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 [email protected]:/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
[email protected]:/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。
[[email protected] dockerbuild]# cd bundles/ [[email protected] bundles]# ls 1.8.2 latest [[email protected] bundles]# cd 1.8.2/ [[email protected] 1.8.2]# ls binary [[email protected] 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 [[email protected] binary]# ./docker version Client: Version: 1.8.2 API version: 1.20 Go version: go1.4.2 Git commit: 0a8c2e3 Built: Tue Sep 15 10:20:40 UTC 2015 OS/Arch: linux/amd64 Error response from daemon: client and server don‘t have same version (client API version: 1.20, server API version: 1.19)
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。
