Docker 安装 [ 技术分享 ]

docker 系统版本要求 **64-bit 系统 kernel 3.10+** 

1.检查内核版本

uname -r

2.确保yum是最新的

yum update

3.添加 yum 仓库

tee /etc/yum.repos.d/docker.repo <<-'EOF'
[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg
EOF

4.安装 Docker

yum install -y docker-engine

5.启动docker

systemctl start docker.service

6.验证安装是否成功(有client和service两部分表示docker安装启动都成功了)

docker version
