安装docker (centos7.6)

Docker

更新yum包

sudo yum update

卸载旧版本
sudo yum remove docker docker-common docker-selinux docker-engine

安装软件包， yum-util 提供yum-config-manager功能，device-mapper-persistent-data和lvm2是devicemapper驱动依赖
sudo yum install -y yum-utils device-mapper-persistent-data lvm2

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

查看所有仓库中所有docker版本，可以选择特定版本安装
yum list docker-ce --showduplicates | sort -r

安装docker
sudo yum install docker-ce 安装最新版
sudo yum install docker-ce-xx.xx.x.ce 安装指定版本

开机启动
sudo systemctl enable docker
sudo systemctl start docker

查看安装是否成功
docker version

允许远程访问
vim /usr/lib/systemd/system/docker.service

在 ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock 后面添加-H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
变成ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
systemctl daemon-reload
systemctl restart docker

使用Docker 中国加速器

        "live-restore": true
}

systemctl restart docker
