Docker container not starting with ubuntu image docker start

Question

If I use docker container run ubuntu to run a container directly from an Ubuntu image, I can easily restart it using docker start CONTAINER_ID. When I run the container using the image using docker run ID_IMAGE, however, it is completely gone as I quit the pseudo-terminal.

When I tried to restart it, I observed that the status changed, indicating that the primary process starts and then ends. Do you have any ideas?
