1、环境要求

a GitHub account
git
make
docker

1、git 版本 大于 2.2.2

vito@caas:~$ git --version
git version 2.7.4

2、make版本 大于3.8.1

vito@caas:~$ make -v
GNU Make 4.1
Built for x86_64-pc-linux-gnu

3、docker 版本

vito@caas:~$ sudo docker --version
Docker version 17.09.0-ce, build afdb6d4

linux 用户小提示：
如果你的用户没有加入docker组，每次执行docker命令笔记加上sudo，执行下面的命令查看是否加入docker组，下面的命令表示没有加入。所以执行命令的时候必须加入sudo：

vito@caas:~$ getent group docker
docker:x:999:
vito@caas:~$ sudo docker --version
Docker version 17.09.0-ce, build afdb6d4

我们可以执行以下命令把当前用户加入到docker组：
（注意：执行命令后重新启动）

vito@caas:~$ sudo usermod -aG docker username

2、创建docker编译环境

• 首先下载docker源代码：https://github.com/docker/distribution.git

git clone https://github.com/docker/distribution.git

• 切换到源码根目录，发现根目录有一个Dockerfile，用这个Dockerfile创建docker的编译环境，执行创建docker

  镜像的命令：

vito@caas:~/docker/moby$ sudo make BIND_DIR=. shell
Makefile:115: The docker client CLI has moved to github.com/docker/cli. For a dev-test cycle involving the CLI, run:
 DOCKER_CLI_PATH=/host/path/to/cli/binary make shell 
 then change the cli and compile into a binary at the same location.

docker build   -t "docker-dev:master" -f "" .

踩过的坑

• 由于有些下载地址可能被屏蔽，中途的错误可以手动修改，改为国内下载地址，例如：golang的下载地址，各种版本都可以在这个地址找到：https://studygolang.com/dl，我们替换Dockerfile中的地址为国内地址：

• 再次执行 ：sudo make BIND_DIR=. shell,执行到第30步的时候报错：

Step 30/39 : RUN ./contrib/download-frozen-image-v2.sh /docker-frozen-images    buildpack-deps:jessie@sha256:85b379ec16065e4fe4127eb1c5fb1bcc03c559bd36dbb2e22ff496de55925fa6   busybox:latest@sha256:32f093055929dbc23dec4d03e09dfe971f5973a9ca5cf059cbfb644c206aa83f  debian:jessie@sha256:72f784399fd2719b4cb4e16ef8e369a39dc67f53d978cd3e2e7bf4e502c7b793   hello-world:latest@sha256:c5515758d4c5e1e838e9cd307f6c6a0d620b5e07e6f927b07d05f6d12a1ac8d7

经过分析是因为脚本中存在windows的换行符，使用命令替换掉换行符：

sed -i 's/\r$//' contrib/download-frozen-image-v2.sh

会把 .sh 中的\r 替换成空白,再次编译，pass

• 执行过程中，如果发现脚本中用到的有些文件夹不存在，可能是因为权限不够，造成创建的某些文件夹失败，解决方案是切换到root用户下执行：make BIND_DIR=. shell
• 镜像下载慢问题：由于sh脚本中定义的镜像仓库都是国外的仓库，下载镜像比较慢，甚至终端，可以把镜像仓库替换为国内的镜像仓库，例如：download-frozen-image-v2.sh文件中的registryBase

registryBase='https://registry-1.docker.io'
authBase='https://auth.docker.io'
authService='registry.docker.io'

替换为：
registryBase='https://5162s31v.mirror.aliyuncs.com'
authBase='https://auth.docker.io'
authService='registry.docker.io'

解决办法1，修改/hack/dockerfile/install-binaries.sh文件

    url=https://download.docker.com/linux/static
    curl -Ls $url/$DOCKERCLI_CHANNEL/$arch/docker-$DOCKERCLI_VERSION.tgz | \
    tar -xz docker/docker
    mv docker/docker /usr/local/bin/
    rmdir docker
改为：
    url=https://download.docker.com/linux/static
    curl -o docker-$DOCKERCLI_VERSION.tgz $url/$DOCKERCLI_CHANNEL/$arch/docker-$DOCKERCLI_VERSION.tgz | \
    tar -xzf docker-$DOCKERCLI_VERSION.tgz
    mv docker/docker /usr/local/bin/
    rmdir docker

上马的方法如该不行，有个稍微麻烦的办法，自己下载docker-17.06.0-ce.tgz文件：https://download.docker.com/linux/static/edge/x86_64/docker-17.06.0-ce.tgz，解压缩，然后放在自己的github上，在github上自己的账户下创建public项目docker，把解压缩的文件上传到githua中。然后修改里面的语句为git clone，具体修改后内容如下：

        url=https://download.docker.com/linux/static
        git clone https://github.com/liujb0319/docker.git
        mv docker/docker /usr/local/bin/
        rm -rf docker
