Simple operation of installing vi command 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 again:

apt-get install vim

Just run the command.
