centos docker 安装

centos docker 安装 参考网站 https://docs.docker.com/install/linux/docker-ce/centos/

一、删除原有docker

$ sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

二、安装

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

修改docker-ce地址为阿里地址，加速

$ sudo yum-config-manager \
    --add-repo \
    http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

$ sudo yum install -y docker-ce docker-ce-cli containerd.io

三、修改默认仓库地址为163仓库加速镜像下载

mkdir -p /etc/docker
echo '{"registry-mirrors": ["http://hub-mirror.c.163.com"] }' > /etc/docker/daemon.json
systemctl daemon-reload
systemctl start docker
docker info

四、docker 卸载

systemctl stop docker
yum -y remove docker-ce
rm -rf /var/lib/docker
rm -rf /etc/docker
