需求
安装docker运行环境
准备条件
- 一台vps(本文使用阿里云香港 - centos7.7)
- 一台能ssh连接到vps的本地电脑 (推荐连接工具xshell)
安装步骤
安装docker
curl -fssl https://get.docker.com -o get-docker.sh sh get-docker.sh --mirror aliyun
配置docker访问加速
tee /etc/docker/daemon.json <<-'eof' { "registry-mirrors": [ "https://ze9vyrof.mirror.aliyuncs.com", "https://registry.docker-cn.com", "http://f1361db2.m.daocloud.io", "https://docker.mirrors.ustc.edu.cn" ] } eof
创建用户并加入docker组
useradd -g docker docker usermod -ag docker docker
加入开启启动、启动docker应用
systemctl enable docker systemctl start docker
测试 docker 是否安装正确
docker run hello-world unable to find image 'hello-world:latest' locally latest: pulling from library/hello-world 0e03bdcc26d7: pulling fs layer latest: pulling from library/hello-world 0e03bdcc26d7: pull complete digest: sha256:8e3114318a995a1ee497790535e7b88365222a21771ae7e53687ad76563e8e76 status: downloaded newer image for hello-world:latest hello from docker! this message shows that your installation appears to be working correctly. to generate this message, docker took the following steps: 1. the docker client contacted the docker daemon. 2. the docker daemon pulled the "hello-world" image from the docker hub. (amd64) 3. the docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. the docker daemon streamed that output to the docker client, which sent it to your terminal. to try something more ambitious, you can run an ubuntu container with: $ docker run -it ubuntu bash share images, automate workflows, and more with a free docker id: https://hub.docker.com/ for more examples and ideas, visit: https://docs.docker.com/get-started/
