 Docker version 18.09.4, build d14af54266

• The company’s network needs to be configured with an agent to get online, and the agent settings have been modified in the virtual machine. As shown below,

cat /etc/systemd/system/docker.service.d/http-proxy.conf
 
 
 [Service]
 Environment="HTTP_PROXY=http://proxy.cmcc:8080/"
 Environment="HTTPS_PROXY=http://proxy.cmcc:8080"
 ~

• The mirror image of 163 is configured in daemon.json

cat /etc/docker/daemon.json
 
 {
 "registry-mirrors": ["http://hub-mirror.c.163.com"]
 }

Well, I think the source or network has not been configured properly, but now I really don’t know how to modify it. Which great god can help solve it or give some ideas?
I am also a docker learner. I hope you can help me a lot. I am very grateful.
