To install Docker and related components on an Ubuntu server, you can follow these steps:

1. Update Package Index:

   sudo apt update
   

2. Install Required Packages: Install packages that allow apt to use packages over HTTPS.

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

3. Add Docker’s Official GPG Key:

   curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
   

4. Add Docker Repository:

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

5. Update Package Index Again:

   sudo apt update
   

6. Install Docker Engine:

   sudo apt install docker-ce
   

7. Start and Enable Docker Service:

   sudo systemctl start docker
   sudo systemctl enable docker
   

8. Verify Docker Installation:

   sudo docker --version
   

9. Install Docker Compose: Docker Compose allows you to define and run multi-container Docker applications. To install Docker Compose, follow these steps:

   sudo curl -L "https://github.com/docker/compose/releases/download/$(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep tag_name | cut -d '"' -f 4)/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
   

10. Apply Executable Permissions to the Docker Compose Binary:

    sudo chmod +x /usr/local/bin/docker-compose
    

11. Verify Docker Compose Installation:

    docker-compose --version
    

12. Optional: Install Docker Machine: Docker Machine is a tool to provision and manage Docker hosts. If you need it, install it using:

    sudo curl -L "https://github.com/docker/machine/releases/download/$(curl -s https://api.github.com/repos/docker/machine/releases/latest | grep tag_name | cut -d '"' -f 4)/docker-machine-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-machine
    

13. Apply Executable Permissions to Docker Machine Binary:

    sudo chmod +x /usr/local/bin/docker-machine
    

14. Verify Docker Machine Installation: bash docker-machine --version If you need to manage Docker as a non-root user, you can add your user to the docker group with:

sudo usermod -aG docker $USER

Then log out and log back in for the group change to take effect.
