安装依赖库
# sudo apt-get install -y apt-transport-https ca-certificates curl software-properties-common
添加Docker官方GPG key
# curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
设置Docker稳定版仓库
# sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
更新apt源索引
# sudo apt-get update
安装最新版Docker CE（社区版）
# sudo apt-get install -y docker-ce
检查Docker CE是否安装正确，出现 Hello from Docker! ，则表示安装成功
# sudo docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 1b930d010525: Pull complete Digest: sha256:4df8ca8a7e309c256d60d7971ea14c27672fc0d10c5f303856d7bc48f8cc17ff 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/
安装docker-compose
$ sudo curl -L https://github.com/docker/compose/releases/download/1.25.0-rc4/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose $ sudo chmod +x /usr/local/bin/docker-compose $ docker-compose version
设置权限，不用每次都输入sudo
$ sudo usermod -a -G docker docker
docker常用命令
# # 启动docker # sudo service docker start # # 停止docker # sudo service docker stop # # 重启docker # sudo service docker restart
