Docker Registry 简单安装部署(无安全认证)

1.下载registry 镜像

# docker pull registry:2

 2.启动docker registry

docker run -idt -v /opt/registry:/var/lib/registry -p 5000:5000 --restart=always --name registry registry:2

i:	保持sdtin开放状态
d:	使容器以守护进程方式后台运行，并打印容器id
t:	分配一个tty（虚拟终端设备）
v:	绑定挂载一个容器内的路径到宿主机路径
p:	映射一个容器的端口到宿主机端口
restart:	当容器退出时的重启策略
name:	给容器命名一个名称

3.查看docker registry 进程：

$docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
25cdc31fc97a        registry:2          "/entrypoint.sh /e..."   10 minutes ago      Up 10 minutes       0.0.0.0:5000->5000/tcp   registry

 4.验证可用性

   . 4.1 打tag

docker tag ubuntu:12.04 127.0.0.1:5000/ubuntu:12.04

   

    4.2 查看本地镜像

$docker images
REPOSITORY              TAG                 IMAGE ID            CREATED             SIZE
ubuntu                  12.04               5b117edd0b76        6 months ago        104MB

    

    4.3 push镜像到私有仓库：

$docker push 127.0.0.1:5000/ubuntu

    4.4 查看宿主机映射目录

$ll /opt/registry/docker/registry/v2/repositories/
drwxr-xr-x 5 root root 4096 Oct 24 15:21 ubuntu

    4.5 查看docker registry中的镜像

    

$curl http://127.0.0.1:5000/v2/_catalog
{"repositories":["ubuntu"]}

   4.6 在docker registry中下载镜像:

  

$docker rmi 127.0.0.1:5000/ubuntu:12.04
Untagged: 127.0.0.1:5000/ubuntu:12.04
$docker pull 127.0.0.1:5000/ubuntu:12.04
12.04: Pulling from ubuntu
Status: Downloaded newer image for 127.0.0.1:5000/ubuntu:12.04
$docker images
REPOSITORY              TAG                 IMAGE ID            CREATED             SIZE
127.0.0.1:5000/ubuntu   12.04               5b117edd0b76        6 months ago        104MB
