To install Docker on Ubuntu, you will need to follow these steps:

  1. First, update the package manager index by running the following command:
1
sudo apt update


  1. Next, install the dependencies required to add a new repository to your system by running the following command:
1
sudo apt install apt-transport-https ca-certificates curl software-properties-common


  1. Add the GPG key for the official Docker repository to your system by running the following command:
1
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -


  1. Add the Docker repository to your system by running the following command:
1
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"


  1. Once the repository is added, update the package manager index again by running the following command:
1
sudo apt update


  1. Finally, install Docker by running the following command:
1
sudo apt install docker-ce


After installation is complete, you can verify that Docker is running by running the following command:

1
sudo systemctl status docker


This will display the status of the Docker service, including whether it is running or not. If the service is running, you should see a message similar to the following:
