# 第一次创建 docker run -p 8080:80 --name mydestop dorowu/ubuntu-desktop-lxde-vnc # 保存 docker commit $(docker ps -aq) mydestop:1.0; docker save -o mydestop.tar mydestop:1.0 # 停止和删除所有的容器和镜像(用完之后, 可以执行该命令, 删除镜像, 以免影响速度和空间) docker stop $(docker ps -aq); docker rm $(docker ps -aq); docker rmi $(docker images -aq); # 导入本地桌面镜像, 并启动 (每次运行可以用该命令) docker load --input mydestop.tar; docker run -p 8080:80 $(docker images -aq) # 导入本地桌面 docker load --input mydestop.tar; # 后台运行任务 nohup docker run -p 8080:80 $(docker images -aq) 2>&1 & # 删除后台运行 ps ux kill -9 填写实际的进程pid号
也可以让本地文件和docker镜像文件共享, 在https://github.com/codespaces 中可用下面命令
# 直接运行任务
docker run -p 8080:80 -it -v /workspaces:/root $(docker images -aq)
# 后台运行任务
nohup docker run -p 8080:80 -it -v /workspaces:/root $(docker images -aq) 2>&1 &
如果8080端口被占用, 可以考虑换成别的端口, 只需把8080换成别的四位数即可.
这一步的目的使彻底解决文件下载问题
也可以采用网盘
