Docker安装的镜像没有关机命令怎么办

Question

安装的Docker的官方镜像ubuntu18.04

PS C:\Users\17293> docker images
REPOSITORY   TAG       IMAGE ID       CREATED       SIZE
ubuntu       18.04     4eb8f7c43909   2 weeks ago   63.1MB
PS C:\Users\17293> docker ps -a
CONTAINER ID   IMAGE          COMMAND   CREATED       STATUS       PORTS     NAMES
12910e0535ad   ubuntu:18.04   "bash"    2 hours ago   Up 2 hours             mineos

试了poweroff、shutdown和halt都没有，那我怎么关机呢？

root@12910e0535ad:/# uname -a

root@12910e0535ad:/# poweroff
bash: poweroff: command not found
root@12910e0535ad:/# shutdown
bash: shutdown: command not found
root@12910e0535ad:/# halt
bash: halt: command not found

Answer 1

docker stop xxx
docker kill xxx

如果你的镜像运行时命令是 docker run --rm，退出之后修改就消失了，如果不是，退出之后，还能继续运行。
