在 ubuntu Docker 映像中缺少 ip 命令

当我试图在 ubuntu docker 容器中执行 ip 命令时，我得到:

找不到命令。

Ubuntu 版本:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=18.04
DISTRIB_CODENAME=bionic
DISTRIB_DESCRIPTION="Ubuntu 18.04.1 LTS"

我应该为该命令安装什么软件包？

谢谢

You could use apt-file search to determine the command in which package. From my ubuntu16.04, it tells me to install iproute2, I think 1804 similar.

1. Get what package need to be installed:

$ apt-file search --regexp 'bin/ip$'
iproute2: /bin/ip
iproute2: /sbin/ip

2. Install the package:

$ apt install -y iproute2
...

3. Verify the package is installed:

$ dpkg -l iproute2
ii  iproute2    4.3.0-1ubuntu3      amd64      networking and traffic control tools

Don't forget to install the iproute2

apt install iproute2

And then you may use ip command.

Once you have created your docker with ubuntu latest or any of version image and crated a ubuntu container, you have to run your ubuntu container and install the following for the basic networking command,

apt-get update


apt-get upgrade


apt-get install -y net-tools


apt-get update

I hope it could help:
