docker 安裝

yum源 準備

curl  http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker-ce.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo           

安裝依賴包

yum install -y yum-utils device-mapper-persistent-data lvm2
yum list docker-ce.x86_64 --showduplicates | sort -r
yum install -y docker-ce           

安裝docker-ce

yum install -y --setopt=obsoletes=0 \
docker-ce-17.03.2.ce-1.el7.centos.x86_64 \
docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch
