docker - 如何在 Fedora Docker 上使用“ping”

问题描述

在容器根/目录中，我键入

ping

并得到

bash: ping: command not found

然后我输入

yum install iputils

然后我输入

ping

我得到

bash: /usr/bin/ping: Operation not permitted

然后我做

sudo ping

我得到

bash: sudo: command not found

所以我输入

yum install sudo

我输入

sudo ping

我得到

sudo: unable to execute /bin/ping: Operation not permitted

在这一点上，我放弃了，把手举在空中......

那么我该如何使用pingutil，并且我还想使用其他 utils，例如hostname和ifconfig
