linux - 能否在Docker容器内读取宿主机的进程信息(ps)和一些系统状态(df)

Answer 1

1.In docker container, you can add dockerhost in /etc/hosts:

127.0.0.1    localhost
192.168.0.109   dockerhost  # host ip

2.In docker container,run command as following:

ssh root@dockerhost 'df -h'

NOTE:You can add docker ssh file id_rsa.pub in dockerhost, so you do not have to input password every time when excuting the command.
