下载deb安装包
官方deb安装包列表
https://download.docker.com/linux/debian/dists/buster/pool/stable/amd64/
依次下载containerd.io、docker-ce-cli 和 docker-ce 三个软件包
wget https://download.docker.com/linux/debian/dists/buster/pool/stable/amd64/containerd.io_1.2.6-3_amd64.deb
wget https://download.docker.com/linux/debian/dists/buster/pool/stable/amd64/docker-ce-cli_19.03.5~3-0~debian-buster_amd64.deb
wget https://download.docker.com/linux/debian/dists/buster/pool/stable/amd64/docker-ce_19.03.5~3-0~debian-buster_amd64.deb
我缓存到内网服务器上了，使用内网地址下载
wget http://172.16.20.10/wangrui/deb/containerd.io_1.2.6-3_amd64.deb
wget http://172.16.20.10/wangrui/deb/docker-ce-cli_19.03.5~3-0~debian-buster_amd64.deb
wget http://172.16.20.10/wangrui/deb/docker-ce_19.03.5~3-0~debian-buster_amd64.deb
安装deb
dpkg -i containerd.io_1.2.6-3_amd64.deb
dpkg -i docker-ce-cli_19.03.5~3-0~debian-buster_amd64.deb
dpkg -i docker-ce_19.03.5~3-0~debian-buster_amd64.deb
验证docker环境
docker info
docker run --rm hello-world
卸载
“apt-get purge” 卸载命令需要逐条执行
apt-get purge docker-ce
apt-get purge docker-ce-cli
apt-get purge containerd.io
查看是否卸载完毕
apt list --installed | grep docker
apt list --installed | grep containerd.io
