docker 版本說明

docker自1.13版本以后發(fā)行版本有了很大不同
分為了CE(community edition)社區(qū)版和EE(enterprise edition)企業(yè)版

• 現(xiàn)在Docker改為基于YY.MM的版本（像Ubuntu）
• 用戶可以選擇Stable（發(fā)布較慢）或者Edge（發(fā)布較快）版本。
• ce由社區(qū)維護和提供技術(shù)支持，為免費版本
• ee版本為收費版本，由售后團隊和技術(shù)團隊支持技術(shù)支持
• 更多的收費標(biāo)準(zhǔn)看docker官網(wǎng)

docker 安裝包說明

• docker.io: is used to be very old version in default ubuntu repo (can skip here)
• docker-engine: is used before release 1.13.x
• docker-ce: since 17.03

docker-engine 安裝

yum 安裝

cat > /etc/yum.repos.d/docker.repo <<EOF

[dockerrepo]

name=Docker Repository

baseurl=https://mirrors.aliyun.com/docker-engine/yum/repo/main/centos/7/

enabled=1

gpgcheck=0

gpgkey=https://yum.dockerproject.org/gpg

EOF
### yum 
yum -y install docker-engine

啟動管理

systemctl start docker
systemctl enable docker
systemctl status docker

docker-ce 安裝

yum安裝

yum 工具

安裝所需的軟件包 yum-utils提供了yum-config-manager 效用
并device-mapper-persistent-data和lvm2由需要devicemapper存儲驅(qū)動程序。

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

添加鏡像源

sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

將軟件包添加至本地緩存

sudo yum makecache fast

安裝docker-ce

sudo yum install docker-ce

啟動docker
