docker search 命令报docker Error response from daemon: Get https://registry-1.docker.io
- docker hub源的问题，就是访问不了,可以用中科大的镜像源http://mirrors.ustc.edu.cn/help/dockerhub.html
- 有些image 在中科大没有咋办？死磕，用 默认的docker hub 源，但是连不上，咋办呢？dig 获取可用ip：简单来说就是用dig命令发现registry-1.docker.io和index.docker.io域名的可用ip地址，然后编辑hosts文件，将可用ip与域名绑定，例如
52.87.94.70 registry-1.docker.io
52.72.177.78 index.docker.io
缺点就是动不动过个一两天ip会变，得重新获取ip
[root@micocube ~]# docker search nginx

docker run image 之后，怎么进入到container 里边执行命令？--执行docker exec -it containerId bash
[root@micocube ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c107f307366f xuping/clipbucket:v1.0 "/usr/bin/supervisord" 5 hours ago Up 3 hours 0.0.0.0:2222->22/tcp, 0.0.0.0:8081->80/tcp stoic_bose
[root@micocube ~]# docker exec -it c107 bash
root@c107f307366f:/#
退出只要执行exit命令就好了，不会把容器退出
