How to install YUM in a Docker container

YUM (Yellowdog Updater, Managed) is a command-line tool for managing RPM packages. Here is how to install YUM in a Docker container:

Step 1: Create a container from the base image

 <code>docker run -it --rm centos:latest</code>

Step 2: Update the package information of the container

 <code>yum update</code>

Step 3: Install YUM

 <code>yum install yum</code>

Detailed steps:

1. Create containers from the base image:

   • Use the docker run command to create a container based on CentOS image.
   • -it flag enables interactive terminals.
   • --rm flag automatically deletes the container after it exits.

2. Update package information:

   • Run the <code>yum update</code> command to update the package information in the container. This will get a list of all available updates.

3. Install YUM:

   • Run the <code>yum install yum</code> command to install YUM. This will install the YUM suite along with all required dependencies.

Once the installation is complete, you can use YUM in the container to manage the packages. You can install, update, or delete RPM packages using the following commands:

• Installation: yum install <package_name></package_name>
• Update: yum update <package_name></package_name>
