  "account": "Docker containers sometimes fail to launch, resulting in unexpected termination. To diagnose the issue, you need to access a debug console. Begin by identifying the failing container using the command 'docker ps -a'. For instance, the container might be named 'blog-testprod-django-testprod-1'. To create a new image from the failing container, use the command 'docker commit container_id new_image_name'. Replace 'container_id' with the ID of the failing container and 'new_image_name' with the desired name for the new image. Next, run the new image in a detached mode with an interactive shell by using the command 'docker run -it --rm --entrypoint /bin/bash new_image_name'. If the '/bin/bash' command is not available, use '/bin/sh' instead. This process allows you to execute any diagnostic commands necessary to pinpoint the cause of the container's failure.",

But when I try to launch it: docker compose up -d But for some reason is unable to be launched and it is unexpectedly terminated.
