Solve the problem of ifconfig being unavailable in docker

Recently, when I was learning docker, I found that ifconfig was used to query the network status in the docker container.

The command not found message appeared. After searching the information, I learned that the images on Docker are installed in the lightest way, and some commands need to be installed by yourself.

Solution:

yum install net-tools

If yum is not available, you can use apt-get install net-tools to solve it

Supplement: Install vim, telnet, ifconfig commands in docker container

When using a docker container, sometimes vim is not installed in it, and when you type the vim command, it prompts: vim: command not found. At this time, you need to install vim, but when you type the apt-get install vim command, it prompts:

Reading package lists... Done

Building dependency tree

Reading state information... Done

E: Unable to locate package vim

At this time, you need to type: apt-get update,

The purpose of this command is to synchronize the indexes of the sources listed in /etc/apt/sources.list and /etc/apt/sources.list.d so that the latest software packages can be obtained.

After the update is complete, type the command: apt-get install vim.

apt-get install telnet Install telnet

apt-get install net-tools Install ifconfig

The above is my personal experience. I hope it can give you a reference. I also hope that you will support 123WORDPRESS.COM. If there are any mistakes or incomplete considerations, please feel free to correct me.
