确认Golang环境安装成功，并配置$GOPATH环境变量，例如/go。
go version go1.9.2 linux/amd64
安装
1、获取源码:
wang@wang:~/go/src/github.com/docker$ git clone https://github.com/docker/distribution.git
输出如下：
Cloning into 'distribution'...
remote: Enumerating objects: 29, done.
remote: Counting objects: 100% (29/29), done.
remote: Compressing objects: 100% (26/26), done.
remote: Total 19770 (delta 5), reused 16 (delta 3), pack-reused 19741
Receiving objects: 100% (19770/19770), 12.77 MiB | 348.00 KiB/s, done.
Resolving deltas: 100% (10665/10665), done.
Checking connectivity... done.
Checking out files: 100% (1188/1188), done.
2、将自带的模板配置文件复制到/etc/docker/registry/路径下，创建存储目录/var/lib/registry：
wang@wang:~/go/src/github.com/docker/distribution$ sudo cp cmd/registry/config-dev.yml /etc/docker/registry/config.yml
wang@wang:~$ sudo mkdir -p /var/lib/registry
3、编译：
wang@wang:~/go/src/github.com/docker/distribution$ make PREFIX=/go clean binaries
输出如下：
+ clean
+ bin/registry
+ bin/digest
+ bin/registry-api-descriptor-template
+ binaries
wang@wang:~/go/src/github.com/docker/distribution/bin$ ./registry -v
./registry github.com/docker/distribution v2.7.0
4、启动：
wang@wang:~/go/src/github.com/docker/distribution/bin$ ./registry serve /etc/docker/registry/config.yml
5、访问本地5000端口，看到返回“200 OK”，则说明成功了。
wang@wang:~$ curl -i 127.0.0.1:5000/v2/
输出：
HTTP/1.1 200 OK
Content-Length: 2
Content-Type: application/json; charset=utf-8
Docker-Distribution-Api-Version: registry/2.0
X-Content-Type-Options: nosniff

{}
测试
1、启动
root@wang:/home/wang/go/src/github.com/docker/distribution/bin# ./registry serve /etc/docker/registry/config.yml
打印：
INFO[0000] debug server listening :5001
WARN[0000] No HTTP secret provided - generated random secret. This may cause problems with uploads if multiple registries are behind a load-balancer. To provide a shared secret, fill in http.secret in the configuration file or set the REGISTRY_HTTP_SECRET environment variable. environment=development go.version=go1.9.2 instance.id=584580dc-8ae9-4a2e-8446-0eac6947c407 service=registry version=v2.7.0

INFO[0000] providing prometheus metrics on /metrics
INFO[0000] listening on [::]:5000
（我这里不用root权限启动的话，在把镜像push到Registry的时候会提示“没有权限创建文件夹”。）
2、给已存在的镜像hello-world：latest打个标记
wang@wang:~$ docker tag hello-world:latest 127.0.0.1:5000/hello-world:1.11
wang@wang:~$ docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
registry latest 2e2f252f3c88 2 months ago 33.3 MB
hello-world latest f2a91732366c 12 months ago 1.85 kB
127.0.0.1:5000/hello-world 1.11 f2a91732366c 12 months ago 1.85 kB
3、把标记的镜像push到Registry
wang@wang:~$ docker push 127.0.0.1:5000/hello-world:1.11
The push refers to a repository [127.0.0.1:5000/hello-world]
f999ae22f308: Pushed
1.11: digest: sha256:0b1396cdcea05f91f38fc7f5aecd58ccf19fb5743bbb79cff5eb3c747b36d909 size: 524
4、删除刚刚打过标记的镜像（只是去掉标记）
wang@wang:~$ docker rmi 127.0.0.1:5000/hello-world:1.11
Untagged: 127.0.0.1:5000/hello-world:1.11
Untagged: 127.0.0.1:5000/hello-world@sha256:0b1396cdcea05f91f38fc7f5aecd58ccf19fb5743bbb79cff5eb3c747b36d909
wang@wang:~$ docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
registry latest 2e2f252f3c88 2 months ago 33.3 MB
hello-world latest f2a91732366c 12 months ago 1.85 kB
5、用 curl 查看仓库中的镜像
wang@wang:~$ curl 127.0.0.1:5000/v2/_catalog
{"repositories":["hello-world"]}
或者
wang@wang:~$ curl http://localhost:5000/v2/hello-world/tags/list
{"name":"hello-world","tags":["1.11"]}
如上打印说明已经push成功了
6、前面已经删除已有镜像，尝试从私有仓库中下载这个镜像
wang@wang:~$ docker pull 127.0.0.1:5000/hello-world:1.11
打印：
1.11: Pulling from hello-world
Digest: sha256:0b1396cdcea05f91f38fc7f5aecd58ccf19fb5743bbb79cff5eb3c747b36d909
Status: Downloaded newer image for 127.0.0.1:5000/hello-world:1.11
wang@wang:~$ docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
registry latest 2e2f252f3c88 2 months ago 33.3 MB
hello-world latest f2a91732366c 12 months ago 1.85 kB
127.0.0.1:5000/hello-world 1.11 f2a91732366c 12 months ago 1.85 kB
pull成功了，简单测试就结束了。
wang@wang:~$ docker tag 127.0.0.1:5000/hello-world:1.11 hello-world:1.11
wang@wang:~$ docker rmi 127.0.0.1:5000/hello-world:1.11
Untagged: 127.0.0.1:5000/hello-world:1.11
Untagged: 127.0.0.1:5000/hello-world@sha256:0b1396cdcea05f91f38fc7f5aecd58ccf19fb5743bbb79cff5eb3c747b36d909
wang@wang:~$ docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
registry latest 2e2f252f3c88 2 months ago 33.3 MB
hello-world 1.11 f2a91732366c 12 months ago 1.85 kB
hello-world latest f2a91732366c 12 months ago 1.85 kB
其他ip在这个仓库pull镜像的设置：
修改/etc/docker下的daemon.json文件，没有的创建。内容如下：
{
"registry-mirrors": ["https://registry.docker-cn.com"]，
"insecure-registries": ["本机ip:5000"]
}
需要符合json规范，否则Docker无法启动
重启docker服务：
sudo service docker restart
docker pull 本机ip:5000/hello-world:1.10
