一、安装epel源
yum install epel-release -y
二、添加docker源
yum install -y yum-utils
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
三、查看当前docer安装版本号
yum list docker-ce --show-duplicates
四、安装社区版docker
yum -y install docker-ce
五、创建配置docker的配置文件
docker]# vi /etc/docker/daemon.json
{
"graph": "/data/docker",
"storage-driver": "overlay2",
"insecure-registries": ["registry.access.redhat.com","quay.io"],
"registry-mirrors": ["https://q2gr04ke.mirror.aliyuncs.com"],
"bip": "172.7.5.1/24",
"exec-opts": ["native.cgroupdriver=systemd"],
"live-restore": true
}
graph: docker 工作目录
sotrage-dirver: docer存储驱动模式
insecure-registries:容器仓库
registry-mirrors:仓库加速镜像
bip:容器运行的网络
exec-opts:容器的启动方式
live-restore:当容器引擎中断时，所启动的容器继续运行
六、启动&关闭&重启docker
启动: systemctl start docker
关闭: systemctl stop docker
重启: systemctl restart docker
七、查看当前容器信息
[root@docker docker]# docker info
