Docker是現代軟件開發和DevOps持續集成和部署管道中不可或缺的一部分,大部分公司都使用容器化技術,降低服務器成本。
root@linuxcool:~# apt-get updateroot@linuxcool:~# apt-get -y install apt-transport-https ca-certificates curl software-properties-common
root@linuxcool:~# curl -fsSL https://mirrors.nwafu.edu.cn/docker-ce/linux/ubuntu/gpg | apt-key add -
Docker服務器在國外,如果使用docker.io來安裝docker會非常慢,有時候還會超時斷開導致無法安裝成功;所以,我這里使用的是國內“西北農林科技大學網絡與教育技術中心”鏡像加速,國內還有很多鏡像加速站點,比如:阿里云、騰訊云、網易、清華大學等,
root@linuxcool:~# apt-get -y updateroot@linuxcool:~# apt-get -y install docker-ce
通過以上命令安裝的是docker最新版本,如果要安裝docker,請繼續閱讀下文,
查找Docker-CE的版本

安裝指定版本的Docker-CE,比如要安裝19.03.8~3-0~ubuntu-bionic
root@linuxcool:~# apt-get -y install docker-ce=19.03.8~3-0~ubuntu-bionic
root@linuxcool:~# docker versionClient: Docker Engine - Community Version: 19.03.8 API version: 1.40 Go version: go1.12.17 Git commit: afacb8b7f0 Built: Wed Mar 11 01:25:46 2020 OS/Arch: linux/amd64 Experimental: falseServer: Docker Engine - Community Engine: Version: 19.03.8 API version: 1.40 (minimum version 1.12) Go version: go1.12.17 Git commit: afacb8b7f0 Built: Wed Mar 11 01:24:19 2020 OS/Arch: linux/amd64 Experimental: falsecontainerd: Version: 1.2.13 GitCommit: 7ad184331fa3e55e52b890ea95e65ba581ae3429 runc: Version: 1.0.0-rc10 GitCommit: dc9208a3303feef5b3839f4323d9beb36df0a9dd docker-init: Version: 0.18.0 GitCommit: fec3683
創建daemon.json配置文件
root@linuxcool:~# vim /etc/docker/daemon.json{ "registry-mirrors": ["https://dockerhub.mirrors.nwafu.edu.cn/"] }
默認daemon.json文件不存在,如果daemon.json文件不存在,自己創建
root@linuxcool:~# systemctl daemon-reloadroot@linuxcool:~# systemctl restart docker
root@linuxcool:~# docker infoClient:Debug Mode: falseServer:Containers: 0 Running: 0 Paused: 0 Stopped: 0Images: 0Server Version: 19.03.8Storage Driver: overlay2 Backing Filesystem: Supports d_type: true Native Overlay Diff: trueLogging Driver: json-fileCgroup Driver: cgroupfsPlugins: Volume: local Network: bridge host ipvlan macvlan null overlay Log: awslogs fluentd gcplogs gelf journald json-file local logentries splunk syslogSwarm: inactiveRuntimes: runcDefault Runtime: runcInit Binary: docker-initcontainerd version: 7ad184331fa3e55e52b890ea95e65ba581ae3429runc version: dc9208a3303feef5b3839f4323d9beb36df0a9ddinit version: fec3683Security Options: apparmor seccomp Profile: defaultKernel Version: 5.3.0-51-genericOperating System: Ubuntu 18.04.4 LTSOSType: linuxArchitecture: x86_64CPUs: 8Total Memory: 15.64GiBName: linuxcoolID: K252:G32L:GWWN:J5FE:3MFZ:2ITG:UE7Y:Y26F:QT3Q:2PLS:HCUX:PJYZDocker Root Dir: /var/lib/dockerDebug Mode: falseRegistry: https://index.docker.io/v1/Labels:Experimental: falseInsecure Registries: 127.0.0.0/8Registry Mirrors: https://dockerhub.mirrors.nwafu.edu.cn/Live Restore Enabled: falseWARNING: No swap limit support
Registry Mirrors默認是docker.io,如果看到Registry Mirrors變https://dockerhub.mirrors.nwafu.edu.cn說明配置已經生效。
