Prerequisites to Install Docker on Linux
Before you can install docker Linux, you should know what is docker for Linux, and ensure that your system meets the following prerequisites:
Linux Distribution
Docker is compatible with a wide range of Linux distributions. However, it's most commonly used on distributions like Ubuntu, Debian, CentOS, Red Hat Enterprise Linux (RHEL), and Fedora. Ensure that you have one of these distributions installed on your system.
64-bit Architecture
install docker Linux requires a 64-bit Linux distribution. Verify that your system is running a 64-bit version of the operating system.

Kernel-Version
install docker Linux relies on certain features of the Linux kernel, so you should have a relatively recent kernel version. A kernel version of 3.10 or later is recommended for the best compatibility. You can check your kernel version by running the following command:
uname -r
Root or Sudo Access
Docker commands often require root or sudo privileges for execution. Ensure that you have root access or are a member of the sudo group on your Linux system.
Disk Space
Docker images and containers consume disk space. Ensure that you have sufficient free disk space for downloading and storing images and containers. A minimum of 10-20 GB is recommended.

CPU and Memory
Docker containers share the host system's CPU and memory resources. Ensure that your system has an adequate amount of CPU and memory to support the applications and services you plan to run within Docker containers.
Network Connectivity
Docker images are typically downloaded from remote repositories like Docker Hub. Ensure that your system has internet connectivity to fetch Docker images during installation.
Firewall Configuration
If you have a firewall enabled on your Linux system, make sure it allows incoming and outgoing traffic on the necessary Docker-related ports (usually port 2375 and 2376 for the Docker daemon).
Uninstallation of Older Versions
If you previously had Docker installed on your system, consider uninstalling it before installing a newer version to prevent conflicts.
Once you've verified that your system meets these prerequisites, you can proceed with the installation of Docker on your Linux distribution. The installation process may vary slightly depending on your chosen distribution, so consult the official Docker documentation or the documentation for your specific Linux distribution for detailed installation instructions.

How to install docker on a Linux server?
Here is a detailed explanation of how to install Docker on a Linux server :
Installing Docker on a Linux server is a fundamental task for system administrators, enabling efficient containerization of applications and services. Follow these steps to install Docker on a Linux server securely and easily.
1. Update Your System:
Before you begin, it's essential to ensure that your Linux server is up to date. Run the following command to update the package list:
sudo apt update # To install Docker on Debian/Ubuntu-based systems
sudo yum update # For Docker installation on CentOS/RHEL systems
2. Install Docker:
Now, proceed to install Docker on your Linux server. Docker provides a convenient script for this purpose:
curl -fsSL https://get.docker.com -o get-docker.sh
arduino
sudo sh get-docker.sh
This script automatically detects your Linux distribution and installs Docker accordingly. It simplifies the process of installing Docker on a Linux server.
3. Start and Enable Docker:
After Docker is installed, start the Docker service and enable it to start automatically on system boot:
sudo systemctl start docker
sudo systemctl enable docker
4. Verify Docker Installation:
To confirm that Docker is successfully installed on your Linux server, run the following command:
sudo docker --version
This command should display the installed Docker version, indicating that you have successfully installed Docker on your Linux server.
5. Docker Group Membership (Optional):
By default, Docker commands require root or sudo privileges, which can be inconvenient. To run Docker commands without sudo, add your user to the 'docker' group:
sudo usermod -aG docker <your_username>
Replace <your_username> with your actual username. After making this change, you'll need to log out and log back in for the group membership to take effect.
6. Pull and Run Docker Containers:
With Docker installed on your Linux server, you can now pull and run containers for various applications and services. Use the docker pull and docker run commands to start deploying containers as needed.
In summary, learning how to install Docker on a Linux server is a valuable skill for any system administrator. Following these steps to install Docker on a Linux server allows you to harness the power of containerization for efficient application deployment and management on your Linux system.
Executing the Docker Command Without Sudo
After installing docker Linux, To execute Docker commands without using sudo on Linux, you can add your user to the "docker" group. This allows your user to interact with Docker as if they were the root user. Here's how to do it:
Open a terminal window.
Run the following command to add your user to the "docker" group (replace <username> with your actual username):
sudo usermod -aG docker <username>
For example, if your username is "john," you would run:
sudo usermod -aG docker john
Log out of your current session and then log back in. This step is crucial to apply the group changes to your user without requiring a system reboot.
To verify that you can run Docker commands without sudo, open a new terminal window and run a Docker command. For example:
docker --version
You should see the Docker version information displayed without any permission errors.
Now, you can execute Docker commands without needing sudo for each one, making it more convenient to work with Docker as a regular user.

Using the Docker Commands After Installing Docker
After installing docker Linux, Using Docker commands is essential for managing containers, images, and other aspects of your Dockerized applications. Here are some common Docker commands and their basic usage:
Pulling Docker Images:
To download a Docker image from a repository (e.g., Docker Hub), use the docker pull command followed by the image name and optionally the tag (version).
docker pull ubuntu:20.04
Running a Docker Container:
To start a new container from an image, use the docker run command. You can specify options such as port mapping, volume mounting, and more.
docker run -d -p 8080:80 --name my-nginx nginx
Listing Running Containers:
To view a list of currently running containers, use the docker ps command.
docker ps
Listing All Containers (Including Stopped Ones):
To see all containers, including those that are stopped, use the -a option with docker ps.
docker ps -a
Stopping a Running Container:
To stop a running container, use the docker stop command followed by the container's name or ID.
docker stop my-nginx
Starting a Stopped Container:
To start a stopped container, use the docker start command followed by the container's name or ID.
docker start my-nginx
Removing a Container:
To remove a stopped container, use the docker rm command followed by the container's name or ID.
docker rm my-nginx
Inspecting a Container:
To get detailed information about a container, including its configuration and networking, use the docker inspect command.
docker inspect my-nginx
Viewing Docker Images:
To list locally available Docker images, use the docker images command.
docker images
Running a Command Inside a Container:
You can execute a command within a running container using docker exec. For example, to open a shell inside a running container:
docker exec -it my-nginx bash
These are some fundamental Docker commands to help you get started. Docker provides a rich set of commands and options to manage containers, networks, volumes, and more. You can always refer to the official Docker documentation for more details and advanced usage.
Conclusion
