删除镜像和容器

# docker image rm ubuntu:22.04
Untagged: ubuntu:22.04

# docker container rm warp
Error response from daemon: You cannot remove a running container cd7b49132dab2267b2e528cec3a9b1cc989fd1730a44ae328e60d478b3409174. Stop the container before attempting removal or force remove

无法删除正在运行的容器，-f强制删除
# docker container rm warp -f

清理所有停止运行的容器
# docker container prune

分离与连接

使用以下命令创建容器后，容器将被启动并被分离，在后台运行bash，如果bash退出，容器也将退出

docker run    --name warp    -p 8080:8080     -it     -d      ubuntu
-i 让容器的标准输入保持打开
-t 让docker分配一个伪终端并绑定到容器的标准输入上
-d 分离到后台运行

使用 docker attach name 或 docker start -ai warp 即可进入容器，使用 ^P + ^Q 分离容器。
