Sometimes it is difficult to pull the image from Docker Hub in China, so you can configure the image accelerator. Docker official and many domestic cloud service providers provide domestic accelerator services.

Configuring the Acceleration Address

Ubuntu 16.04+, Debian 8+, CentOS 7+

/etc/ docker-daemon. json

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
    "registry-mirrors": [
        "https://1nj0zren.mirror.aliyuncs.com"."https://docker.mirrors.ustc.edu.cn"."http://f1361db2.m.daocloud.io"."https://registry.docker-cn.com"
    ]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
Copy the code

Check whether the accelerator is working

Run the docker info command. If the following information is displayed, the configuration is successful.

Docker Hub image speed measurement

You can use time to count the total time spent before and after mirroring. Remove local image before speed measurement!

$ docker rmi node:latest
$ time docker pull node:latestPulling repository node [...] Real 1m14.078s user 0m0.176s sys 0m0.120SCopy the code
