To install and deploy Docker in Ubuntu, you can follow the steps below:

  1. Update the system software packages:
  2. Update the system with the following commands:
    sudo apt-get update
    sudo apt-get upgrade
  3. Install the dependencies for Docker.
  4. Install apt-transport-https, ca-certificates, curl, and software-properties-common using the following command: sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
  5. Add the GPG key from the official Docker website.
  6. Download the Docker GPG key for Ubuntu and save it in /usr/share/keyrings/docker-archive-keyring.gpg using sudo command.
  7. Add the stable repository from Docker official.
  8. Output the mentioned line of code to the file “/etc/apt/sources.list.d/docker.list” using sudo and suppress the standard output.
  9. Install the Docker engine.
  10. Update your system by running the command “sudo apt-get update” and install Docker by running “sudo apt-get install docker-ce docker-ce-cli containerd.io”.
  11. Verify that Docker is installed correctly:
  12. Execute the command “sudo docker run hello-world.”
  13. Execute Docker commands using a non-root user.
  14. Add the current user to the docker group using the sudo command.
  15. Please log back in to the system to apply the changes to the user group.

After installing and deploying Docker, you can use the “docker run” command to run containers. For example, to run a Ubuntu container named “my-container”, you can execute the following command:

sudo docker run --name my-container -it ubuntu

This will launch an interactive Ubuntu terminal in a new container.

Please note that these steps are only applicable to Ubuntu systems. For other Linux distributions, please refer to the official documentation or respective installation guides.
