一、從docker官方yum源進行安裝
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、安裝和啟動
#安裝sudo yum install docker-engine#啟動sudo systemctl enable docker.service#開機啟動systemctl enable docker.service#驗證安裝sudo docker run hello-world
二、用腳本的方式安裝
curl -sSL https://get.docker.com/ | sh
三、非特權用戶運行 docker 命令
在 CentOS 或 Fedora 上安裝完成 Docker 后,為了能以非 root 用戶運行 docker,你需要把你自己添加進 docker 用戶組,使用如下命令:
sudo usermod -a -G docker $USER
登出,然后再登入,以使組改變生效。
這個時候,你應該可以以一個非特權用戶運行 docker 命令了。
四、使用國內源
1、安裝dao
curl -sSL https://get.daocloud.io/daomonit/install.sh | sh -s 6d3f36d42ae3f3d4237943c65c8f3e5446e49a71
2、使用dao命令
dao pull ubuntu
看起來像這樣:
➜ ~ 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.
