How to install vim/nano in the docker container




Step 1: Identify the Linux Distribution
Before you can update the package index or install Vim or Nano, you need to identify the Linux distribution used in the Docker container. To do this, you can run the following command:

cat /etc/os-release
This will display information about the Linux distribution used in the container, including the name and version.

Step 2: Install the Appropriate Package Manager
Once you have identified the Linux distribution used in the container, you need to install the appropriate package manager.

Debian/Ubuntu
For Debian and Ubuntu, you can use the apt-get package manager. To install it, run the following command:

apt-get update

CentOS/Fedora
For CentOS and Fedora, you can use the yum package manager. To install it, run the following command:

yum update

Alpine
For Alpine, you can use the apk package manager. To install it, run the following command:

apk update
This command will update the package index to ensure that you have access to the latest packages available.

Step 3: Install Vim or Nano
To install Vim or Nano in the Docker container, you need to run the appropriate command for the Linux distribution you are using.

Install Vim

Debian/Ubuntu

apt-get install vim -y

CentOS/Fedora

yum install vim -y

Alpine

apk add vim

Install Nano
Debian/Ubuntu

apt-get install nano -y

CentOS/Fedora

yum install nano -y

Step 4: Verify Installation

or

nano --version
This will show you the version information for the installed program.
