Below, we adopted the most simple image file "hello world", feel Docker.

Because the domestic official connection Docker warehouse is very slow, so we will use the accelerator Docker China in daily use. Docker mirrored by official accelerate, China, users can quickly access the most popular Docker image. The mirror is hosted mainland China, local users will now enjoy faster download speeds and greater stability, enabling more agile develop and deliver Docker applications.

Docker Chinese official mirror can be accelerated by registry.docker-cn.comaccess. The image library contains only popular public image, private image from the still image library in the United States pull.

Docker modify system configuration file corresponding to, the following:

vi  /etc/docker/daemon.json

    "live-restore": true
}

Run the following command to grab the image file from the warehouse to the local.
