安装

Docker 升级​

查找主机上关于Docker的软件包​

rpm -qa | grep docker – – 列出包含docker字段的软件的信息

docker-1.13.1-53.git774336d.el7.centos.x86_64
docker-client-1.13.1-53.git774336d.el7.centos.x86_64
docker-common-1.13.1-53.git774336d.el7.centos.x86_64

使用yum remove卸载软件​

yum remove docker-1.13.1-53.git774336d.el7.centos.x86_64
yum remove docker-client-1.13.1-53.git774336d.el7.centos.x86_64
yum remove docker-common-1.13.1-53.git774336d.el7.centos.x86_64

删除完毕，然后运行命令检查一下，在使用docker命令会提示docker不存在，删除完成。没有该命令或者该目录

使用curl升级到最新版​

curl -fsSL https://get.docker.com/ | sh

镜像加速​

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
    "registry-mirrors": [
        "https://hub-mirror.c.163.com",
        "https://docker.m.daocloud.io",
        "https://ghcr.io",
        "https://mirror.baidubce.com",
        "https://docker.nju.edu.cn"
    ]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
