Install docker on the Linux System

To install Docker and Docker compose on your Linux system, the steps can vary slightly depending on the Linux distribution you’re using.

Here’s a general guide for Ubuntu and Debian-based systems:

1.Update your package index:

sudo apt-get update

2.nstall required packages:
Docker requires a few dependencies, so install them first:

sudo apt-get install apt-transport-https ca-certificates curl software-properties-common

3.Add Docker’s official GPG key:
Docker’s official GPG key ensures that the software package comes from a trusted source.

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo tee /etc/apt/trusted.gpg.d/docker.asc

4.Set up the stable Docker repository:
Add Docker’s official repository to your list of package sources.

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

5.Update your package index again:

sudo apt-get update

6.Install Docker Engine:
Install Docker and Docker compose using the following command:

sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

7.Check Docker status:
After the installation completes, check if Docker is running with the following command:

sudo systemctl status docker

You should see Docker is active and running. If not, you can start it using:

sudo systemctl start docker

8.Verify Docker installation:
Run this command to verify that Docker is correctly installed:

docker --version

Conclusion

This method is the one I referred to with GPT, and I verified that it is useful. Everyone can follow these steps to install Docker on a Linux system because sometimes GPT may make mistakes.
