Common Mistakes

Using -it runs the container interactively, not detached.

Using --rm removes the container after it stops, unrelated to detached mode.

Using -p is for port mapping, not for detached mode.

The -d flag runs the container in detached mode, meaning it runs in the background.

Using -it runs interactively, not detached.

The -d flag must come before the image name to run the container detached.

Using -it instead of -d for detached mode.

Swapping port numbers in the mapping.

Use -d to run detached and -p 8080:80 to map host port 8080 to container port 80.

Using -it instead of -d for detached mode.

Incorrect port mapping format.

Forgetting to name the container.
