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

 

问题：

 在另外一个linux服务器上拉取镜像时提示如下错误：

bill@VirtualBox:~$ docker pull 172.31.50.39:5000/alpine

Using default tag: latest

Error response from daemon: Get https://172.31.50.39:5000/v2/: http: server gave HTTP response to HTTPS client

本人拉取的docker client是ubuntu系统：

VirtualBox:~$ systemctl status docker.service

● docker.service - Docker Application Container Engine

   Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)

 

解决方法：

sudo vim /usr/lib/systemd/system/docker.service  ，加入如下红色部分，具体为registry 地址：

 

ExecStart=/usr/bin/dockerd -H fd:// --insecure-registry=172.31.50.39:5000

 

修改好后重启docker 服务

systemctl daemon-reload 

systemctl restart docker
