注：本文操作以debian12.8 最小化安装环境为host系统。
一、彻底卸载原有的残留
apt-get purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extras二、设置docker的安装源
# Add Docker's official GPG key:
apt update
apt install ca-certificates curl
install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc chmod a+r /etc/apt/keyrings/docker.asc
# Add the repository to Apt sources:
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian \
$(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
tee /etc/apt/sources.list.d/docker.list > /dev/null
apt update三、安装docker 及 docker-compose
apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin四、添加国内镜像源
编写一个脚本，将registry-mirrors 中的内容替换为搜到的可用源
#!/bin/sh
cat <<-EOF > /etc/docker/daemon.json
{
"registry-mirrors": [
"https://docker.linkedbus.com",
"https://docker.xuanyuan.me"
]
}
EOF
systemctl daemon-reload
systemctl restart docker五、安装 excalidraw
docker run -i -t -d --name exdraw -p 8090:80 excalidraw/excalidraw:latest
## 设置 exdraw 这个容器随系统自动启动
docker container update --restart=always exdraw六、打开
