In the centos6 version, if you configure the https_proxy agent of Docker, you only need to add the configuration in the / etc/sysconfig/docker configuration file, but in centos7 you will find that you can no longer use this configuration method for https_proxy configuration, because centos uses systemd to manage the process environment. We need the following configuration to apply the https_proxy configuration to create the directory.

Mkdir / etc/systemd/system/docker.service.d

Create a file

Touch / etc/systemd/system/docker.service.d/http-proxy.conf

Configure the http-proxy.conf file to add the following

[Service]

Environment= "HTTP_PROXY= http://proxy.ip.com:80"

Environment= "NO_PROXY=localhost,127.0.0.0/8,docker-registry.somecorporation.com,11.11.225.50"

Note: be sure to add the private library address to the no_proxy, otherwise, you will not be able to push the private database.

Daemon re-reload and restart docker

Systemctl daemon-reload

Systemctl restart docker

Check whether the variable is loaded

Systemctl show docker-property Environment
