下載deb安裝包
官方deb安裝包列表
https://download.docker.com/linux/debian/dists/buster/pool/stable/amd64/
依次下載containerd.io、docker-ce-cli 和 docker-ce 三個軟件包
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
我緩存到內網服務器上了，使用內網地址下載
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
安裝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
驗證docker環境
docker info
docker run --rm hello-world
卸載
“apt-get purge” 卸載命令需要逐條執行
apt-get purge docker-ce
apt-get purge docker-ce-cli
apt-get purge containerd.io
查看是否卸載完畢
apt list --installed | grep docker
apt list --installed | grep containerd.io
刪除殘留文件
rm -rf /var/lib/docker
rm -rf /var/run/docker
rm -rf /etc/docker
rm -rf /run/docker.sock
rm -rf /var/lib/containerd
rm -rf /run/containerd
rm -rf /opt/containerd
