You can run Docker in the background by using the `-d` or `—detach` option when starting your container.
Here’s a general structure of the command:
```
docker run -d image_name
```
Remember to replace `image_name` with the name of the Docker image you want to run in the background.
This will start the Docker container and place it in the background, detached from your current shell or terminal session.
After running this command, Docker will print the container ID to the console, and then control will be returned to your shell or terminal prompt. You can then continue to use the shell or terminal for other commands, while the Docker container runs in the background.
