How to configure Docker-CE image acceleration in Ubuntu? in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Experimental environment

Operating system: Ubuntu 18.04.4 LTS

LAN IP: 192.168.3.22

Docker is an integral part of modern software development and DevOps continuous integration and deployment pipeline, and most companies use containerization technology to reduce server costs.

Install the necessary system resource library

Root@linuxcool:~$ sudo apt-get updateroot@linuxcool:~$ sudo apt-get-y install apt-transport-https ca-certificates curl software-properties-common

Install GPG certificate

Root@linuxcool:~$ curl-fsSL https://mirrors.nwafu.edu.cn/docker-ce/linux/ubuntu/gpg | sudo apt-key add-

The Docker server is abroad, so it will be very slow to install docker using docker.io, and sometimes it will not be installed successfully due to the timeout. Therefore, I am using the domestic image acceleration of the Network and Educational Technology Center of Northwest University of Agriculture and Forestry Science and Technology, and there are many image acceleration sites in China, such as Aliyun, Tencent Cloud, NetEase, Tsinghua University and so on.

Update the system and install Docker-CE

Root@linuxcool:~$ sudo apt-get-y updateroot@linuxcool:~$ sudo apt-get-y install docker-ce

The latest version of docker is installed through the above command. If you want to install docker, please continue to read the following

Install a specified version of Docker-CE, such as 19.03.8room3-0~ubuntu-bionic

Root@linuxcool:~$ sudo apt-get-y install docker-ce=19.03.8~3-0~ubuntu-bionic

Configure Mirror acceleration

# create daemon.json configuration file root@linuxcool:~$ sudo vim / etc/docker/daemon.json {"registry-mirrors": ["https://dockerhub.mirrors.nwafu.edu.cn/"]}# default daemon.json file does not exist. If the daemon.json file does not exist, create it yourself.

Load configuration and restart docker service

Root@linuxcool:~$ sudo systemctl daemon-reloadroot@linuxcool:~$ sudo systemctl restart docker

Verify that the configuration of image acceleration is effective

Root@linuxcool:~$ sudo docker info Client: Debug Mode: falseServer: Containers: 0 Running: 0 Paused: 0 Stopped: 0 Images: 0 Server Version: 19.03.8 Storage Driver: overlay2 Backing Filesystem:Supports d_type: true Native Overlay Diff: true Logging Driver: json-file Cgroup Driver: cgroupfs Plugins: Volume: local Network: bridge host ipvlan macvlan null overlay Log: awslogs fluentd gcplogs gelf journald json-file local logentries splunk syslog Swarm: inactive Runtimes: runc Default Runtime: runc Init Binary: docker-init containerd version: 7ad184331fa3e55e52b890ea95e65ba581ae3429 runc version: dc9208a3303feef5b3839f4323d9beb36df0a9dd init version : fec3683 Security Options: apparmor seccomp Profile: default Kernel Version: 5.3.0-51-generic Operating System: Ubuntu 18.04.4 LTS OSType: linux Architecture: x86: 64 CPUs: 8 Total Memory: 15.64GiB Name: linuxcool ID: K252:G32L:GWWN:J5FE:3MFZ:2ITG:UE7Y:Y26F:QT3Q:2PLS:HCUX:PJYZ Docker Root Dir: / var/lib/docker Debug Mode: false Registry: https://index.docker.io/v1/ Labels: Experimental: false Insecure Registries: 127.0 . 0.0/8 Registry Mirrors: https://dockerhub.mirrors.nwafu.edu.cn/ Live Restore Enabled: falseWARNING: No swap limit support

Registry Mirrors defaults to docker.io. If you see that Registry Mirrors changes to https://dockerhub.mirrors.nwafu.edu.cn, the configuration is already in effect.
