To run an Ubuntu Docker container, you need to have Docker installed on your system. If you don't have Docker installed, you can follow the instructions on the Docker website to install it.

Once you have Docker installed, you can start by pulling the Ubuntu image from the Docker registry. You can do this by running the following command:

1
docker pull ubuntu

This will download the latest version of the Ubuntu image to your system. Once the image is downloaded, you can run a container using the image by using the docker run command. For example:

1
docker run -it ubuntu

This will start an Ubuntu container and open a terminal inside the container. From here, you can run any command that you would normally run on an Ubuntu system.

Keep in mind that any changes you make inside the container will be lost when the container is stopped. To save changes, you can either commit them to a new Docker image or use Docker volumes to persist data outside of the container. For more information on how to do this, see the Docker documentation.

To run an Ubuntu Docker container, follow these steps:

  1. Install Docker: If you haven't already, install Docker on your system by following the instructions on the Docker website.
  2. Pull the Ubuntu Image: Open a terminal or command prompt and enter the following command to download the Ubuntu image from the Docker registry:
1
docker pull ubuntu


  1. Run the Container: Once the image is downloaded, you can start a container by running the following command:
1
docker run -it ubuntu


The -it flag allows you to interact with the container through a terminal.

  1. Interact with the Container: After running the command, you will be inside the Ubuntu container's shell. You can now run any command as if it were a regular Ubuntu system. For example, you can run:
1
2
apt update
apt install <package>


  1. Exit the Container: To exit the container and stop it, type exit in the container's shell.


Note: By default, any changes made inside the container are lost when it's stopped. To persist changes, you can use Docker volumes to map directories from your host system to the container. This allows you to store and access data outside the container.
