Main Components of Docker

Understanding Docker's key components is essential for effective use:

1. Docker File: A script with instructions to build Docker images.

4. Docker Registry: A storage and distribution system for Docker images.

 Step-by-Step Guide to Installing Docker on Red Hat

 Step 1: Install Yum Utilities

First, you need to install the `yum-utils` package to manage your repositories efficiently. Open your terminal and run:

command: sudo yum install -y yum-utils

 Step 2: Add the Docker Repository

Next, add the Docker repository to your system to ensure you get the latest version. Execute the following command:

command: sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

Step 3: Install Docker

Now, you can install Docker and its associated components. Run the following command to install Docker Engine, CLI, and necessary plugins:

command: sudo yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

 Step 4: Start Docker

Finally, start the Docker service with the command:

command: sudo systemctl start docker

For more detailed information, you can refer to the official Docker documentation [here](https://docs.docker.com/engine/install/centos/).

By following these steps, you will have Docker up and running on your Red Hat Linux system. Happy containerizing!
