服务端

1. 启动命令

   • docker run -d -p 5000:5000 –restart always –name registry registry:2
2. ip地址及验证api

客户端

1. build

   root@swoole_dev:/home/tb/my_docker_helloworld# docker build -t 192.168.1.8:5000/hello_docker:latest .
   Sending build context to Docker daemon  916.5kB
   Step 1/3 : FROM scratch
    ---> 
   Step 2/3 : ADD hello /
    ---> Using cache
    ---> 11b009df24b2
   Step 3/3 : CMD ["/hello"]
    ---> Using cache
    ---> 6c539eb137dd
   Successfully built 6c539eb137dd
   Successfully tagged 192.168.1.8:5000/hello_docker:latest
   
   ## 验证image
   root@swoole_dev:/home/tb/my_docker_helloworld# docker images |grep 192
   192.168.1.8:5000/hello_docker   latest              6c539eb137dd        21 hours ago        913kB
   root@swoole_dev:/home/tb/my_docker_helloworld# 
   

2. 验证服务端

   root@swoole_dev:/home/tb/my_docker_helloworld# telnet 192.168.1.8 5000
   Trying 192.168.1.8...
   Connected to 192.168.1.8.
   Escape character is '^]'.
   

3. 尝试push

   root@swoole_dev:/home/tb/my_docker_helloworld# docker push 192.168.1.8:5000/hello_docker:latest
   The push refers to repository [192.168.1.8:5000/hello_docker]
   Get https://192.168.1.8:5000/v2/: http: server gave HTTP response to HTTPS client
   root@swoole_dev:/home/tb/my_docker_helloworld# 
   ## 应该是安全策略问题，http vs https

4. 解决办法

   vim /etc/docker/deamon.json
   ## 增加第二行
   {
      "registry-mirrors": ["http://d1d9aef0.m.daocloud.io"],
      "insecure-registries":["192.168.1.8:5000"]  
   }
   
   ## 验证结果1
   root@swoole_dev:/home/tb/my_docker_helloworld# vim /etc/docker/daemon.json
   root@swoole_dev:/home/tb/my_docker_helloworld# service docker restart
   root@swoole_dev:/home/tb/my_docker_helloworld# docker push 192.168.1.8:5000/hello_docker:latest
   The push refers to repository [192.168.1.8:5000/hello_docker]
   096f9105d9f4: Pushed 
   latest: digest: sha256:dc9c69395640d5fd7cb9e4f8bd2bdbf788b206a59e942a2a40577d9b1c089934 size: 527
   root@swoole_dev:/home/tb/my_docker_helloworld# 

5. 客户端通过registry api 查看

   • 

6. 如果未成功，尝试如下操作

   vim  /lib/systemd/system/docker.service
   #增加一行
   EnvironmentFile=-/etc/docker/daemon.json
