阿里云服务器：
127.0.0.1(客户端)
127.0.0.2(私有服务器)
127.0.0.2作为私有仓库使用
1.下载镜像
[root@insure ~]# docker pull registry Using default tag: latest latest: Pulling from library/registry 456f9d0bf1d1: Pull complete b7f3f37a05d2: Pull complete d1b2fc1a6bc7: Pull complete 400c20544fd6: Pull complete 48473a72399c: Pull complete Digest: sha256:2a5b47a613fd7e9d28120fa77016554c3dffa8913b6a314ede518447ddc68e2f Status: Downloaded newer image for registry:latest
2.通过镜像启动一个容器
[root@insure ~]# docker run -d -p 5000:5000 -v /opt/data/registry:/tmp/registry registry 223608fc9814b1c7f22b47248d6006f50f322f35c4f8e92c7a9429a9f6104767 [root@insure ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 223608fc9814 registry "/entrypoint.sh /etc…" 5 seconds ago Up 4 seconds 0.0.0.0:5000->5000/tcp eager_euler
命令解析：docker run -d -p 5000:5000 -v /opt/data/registry:/tmp/registry registry
使用官方提供的registry镜像来搭建一套本地的私有仓库环境
通过-v参数将镜像文件存放到本地的指定路径上/opt/data/registry
本地仓库本身就是容器，命令的含义就是下载并创建一个registry容器，创建本地的私有仓库，仓库得路径是/tmp/registry
进入容器内部的命令
[root@insure ~]# docker exec -it 223608fc9814 sh / # ls bin entrypoint.sh home linuxrc mnt root sbin sys usr dev etc lib media proc run srv tmp var
127.0.0.1客户端使用
1.下载一个hello-world镜像
[root@insure ~]# docker pull hello-world Using default tag: latest latest: Pulling from library/hello-world d1725b59e92d: Pull complete Digest: sha256:0add3ace90ecb4adbf7777e9aacf18357296e799f81cabc9fde470971e499788 Status: Downloaded newer image for hello-world:latest
2.给hello-world镜像打个tag，表示新的版本
[root@insure ~]# docker tag hello-world:latest 127.0.0.2:5000/hello-world:latest
3.将新的hello-world镜像上传到私有仓库
[root@insure ~]# docker push 127.0.0.2:5000/hello-world:latest The push refers to repository [127.0.0.2:5000/hello-world] Get https://127.0.0.2:5000/v2/: http: server gave HTTP response to HTTPS client
原因是docker私有仓库服务器，默认是基于https传输的，所以我们需要在客户端192.168.1.160做相关设置，不使用https传输
[root@insure ~]# vi /etc/docker/daemon.json
添加如下内容
{
"registry-mirror": [
"https://registry.docker-cn.com"
],
"insecure-registries": [
"127.0.0.2:5000"
]
}[root@insure /]# vi /lib/systemd/system/docker.service 修改有问题不用管这个
添加如下内容ExecStart=/usr/bin/dockerd --insecure-registry 116.62.163.101:5000
依次执行下面两条命令，重新启动docker
[root@insure ~]# systemctl daemon-reload
[root@insure ~]# systemctl restart docker
再次执行上传到私有仓库的命令，并测试
[root@insure ~]# docker push 127.0.0.2:5000/hello-world:latest The push refers to repository [127.0.0.2:5000/hello-world] 428c97da766c: Pushed latest: digest: sha256:1a6fd470b9ce10849be79e99529a88371dff60c60aab424c077007f6979b4812 size: 524 [root@insure ~]# curl http://127.0.0.2:5000/v2/_catalog {"repositories":["hello-world"]}
删除镜像进行重新下载
[root@insure /]# docker pull 127.0.0.2:5000/hello-world Using default tag: latest latest: Pulling from hello-world d1725b59e92d: Pull complete Digest: sha256:1a6fd470b9ce10849be79e99529a88371dff60c60aab424c077007f6979b4812 Status: Downloaded newer image for 127.0.0.2:5000/hello-world:latest [root@insure /]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE dashboard latest 60ff0c365e46 3 days ago 662MB jdk-8u141 20181222 c717428b1276 3 days ago 578MB tomcat latest ef802ca71927 5 days ago 475MB centos latest 1e1148e4cc2c 2 weeks ago 202MB openjdk latest 8e7eacedab93 2 weeks ago 986MB 127.0.0.2:5000/hello-world latest 4ab4c602aa5e 3 months ago 1.84kB
127.0.0.2私有仓库上面查看上传的镜像
挂载和临时目录都没有找到，查询
[root@insure lib]# find / -name "hello-world" /var/lib/docker/volumes/6fcff317934d3c3f4bbaf1c3c4b6dc240b42b69242d8159e75e283ff2d217e16/_data/docker/registry/v2/repositories/hello-world /var/lib/docker/volumes/efed8eab2f8e536123f218486a9462d41e70bc0c6bb4c019d1b73cf646c878de/_data/docker/registry/v2/repositories/hello-world [root@insure lib]# cd /var/lib/docker/volumes/efed8eab2f8e536123f218486a9462d41e70bc0c6bb4c019d1b73cf646c878de/_data/docker/registry/v2/repositories [root@insure repositories]# ls hello-world [root@insure repositories]# ls dashboard hello-world
成功完成私有仓库的创建、客户端镜像的上传和下载。
说明：客户端和私有仓库在不同机器的同一个局域网之内，所用IP都是实际IP，非映射之后的IP。
