Docker 入门笔记 1

安装配置 repository

确保apt 可以使用HTTPs来访问 repository

sudo apt-get install     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 -

验证添加的GPG key 的fingerprint 正确

$ sudo apt-key fingerprint 0EBFCD88pub   4096R/0EBFCD88 2017-02-22      Key fingerprint = 9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88uid                  Docker Release (CE deb) <[e-mail]>sub   4096R/F273FCD8 2017-02-22

建立stable repository

sudo add-apt-repository \   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \   $(lsb_release -cs) \   stable"

安装docker ce

安装最新版的docker ce

sudo apt-get updatesudo apt-get install docker-ce

为生产环境安装特定版本docker ce

$ apt-cache madison docker-cedocker-ce | 17.09.0~ce-0~ubuntu | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages......//列表显示了可用的repository， 第二列是docker versionsudo apt-get install docker-ce=<VERSION>

查看docker是否正确安装

• docker
• docker info
• docker version

使用示例测试

sudo docker run hello-world

升级docker ce

sudo apt-get updatethen install the new version as you want.

卸载 docker

sudo apt-get purge docker-ce//To delete all images, containers, and volumessudo rm -rf /var/lib/docker

配置 docker

实用non-root user 管理docker

//docker daemon binds to a Unix socket instead of a TCP port, other users can only access it using sudosudo groupadd dockersudo usermod -aG docker $USER//verifydocker run hello-world//如果发生  ~/.docker/ 权限不对的warning， 运行如下命令$ sudo chown "$USER":"$USER" /home/"$USER"/.docker -R$ sudo chmod g+rwx "/home/$USER/.docker" -R

设定启动/停止 docker服务

sudo systemctl enable dockersudo systemctl disable docker

启动停止docker

sudo service docker restart
