一、从docker官方yum源进行安装
1、添加docker官方源
cat >/etc/yum.repos.d/docker.repo <<-EOF[dockerrepo]name=Docker Repositorybaseurl=https://yum.dockerproject.org/repo/main/centos/7enabled=1gpgcheck=1gpgkey=https://yum.dockerproject.org/gpgEOF
2、安装和启动
#安装sudo yum install docker-engine#启动sudo systemctl enable docker.service#开机启动systemctl enable docker.service#验证安装sudo docker run hello-world
二、用脚本的方式安装
curl -sSL https://get.docker.com/ | sh
三、非特权用户运行 docker 命令
在 CentOS 或 Fedora 上安装完成 Docker 后,为了能以非 root 用户运行 docker,你需要把你自己添加进 docker 用户组,使用如下命令:
sudo usermod -a -G docker $USER
登出,然后再登入,以使组改变生效。
这个时候,你应该可以以一个非特权用户运行 docker 命令了。
四、使用国内源
1、安装dao
curl -sSL https://get.daocloud.io/daomonit/install.sh | sh -s 6d3f36d42ae3f3d4237943c65c8f3e5446e49a71
2、使用dao命令
dao pull ubuntu
看起来像这样:
➜ ~ dao pull ubuntuDao from DaoCloudInitializing, Please wait a minuteUsing default tag: latestPulling repository daocloud.io/daocloud/daocloud-toolsetaa5dc2eecd4a: Download completeStatus: Image is up to date for daocloud.io/daocloud/daocloud-toolset:latestdaocloud.io/daocloud/daocloud-toolset: this image was pulled from a legacy registry.
