Thanks ZhipengS!
When I run below step $ docker build -t user:centos-mirror-repository -f Dockerfile . It mentioned Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection
It can work after following below steps. =========================================================== Here is a link to the official docker doc for proxy http:https://docs.docker.com/engine/admin/systemd/#http-proxy A quick outline: First, create a systemd drop-in directory for the docker service: mkdir /etc/systemd/system/docker.service.d Now create a file called /etc/systemd/system/docker.service.d/http- proxy.conf that adds the HTTP_PROXY environment variable: [Service] Environment="HTTP_PROXY=http://proxy.example.com:80/" If you have internal Docker registries that you need to contact without proxying you can specify them via the NO_PROXY environment variable: Environment="HTTP_PROXY=http://proxy.example.com:80/" Environment="NO_PROXY=localhost,127.0.0.0/8,docker- registry.somecorporation.com" Flush changes: $ sudo systemctl daemon-reload Verify that the configuration has been loaded: $ sudo systemctl show --property Environment docker Environment=HTTP_PROXY=http://proxy.example.com:80/ Restart Docker: $ sudo systemctl restart docker
