从主持人：

ps aux | grep java

me@my-host:~/elastic-search-group$ ps aux | grep java
smmsp    20473  106  6.3 4664740 257368 ?

然后执行到容器中：

docker exec -it 473 /bin/bash

并查看过程：

root@473c4548b06f:/usr/share/elasticsearch# ps aux | grep java

从主持人：

sudo kill -9 20473

最终杀死了Docker容器。

现在，我可能会弄错了，但我认为存在完全的流程隔离吗？这应该流向主机吗？
