参考：https://linuxiac.com/how-to-install-docker-on-debian-12-bookworm/
step1
sudo apt update
sudo apt install apt-transport-https ca-certificates curl gnupg
step2:这一步多尝试两次，避免网络原因下载失败
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker.gpg
step3
echo “deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker.gpg] https://download.docker.com/linux/debian bookworm stable” | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
step4
sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
step5
sudo systemctl is-active docker
#显示active，表示安装成功！
#加入自启动（可选）
#systemctl enable docker.service
step6:测试
sudo docker run hello-world
更换docker镜像源
nano /etc/docker/daemon.json
{"registry-mirrors" : ["https://dockerproxy.com","https://hub-mirror.c.163.com","https://mirror.baidubce.com","https://ccr.ccs.tencentyun.com"]
