You can do whatever you want inside the container. If you wanted to update inside it, you can, but it’s probably not worth the effort. The downtime depending on the app can be just a few seconds when you rebuild the container.
I have a container running Watchtower and it checks once a week for any updated images so I can go through and update whatever needs updating myself. IIRC there’s an option to have it automatically update stuff but I don’t know nearly enough yet to be comfortable with that - If something is going to break let me break it myself so I can troubleshoot it haha.
I use Portainer as a GUI docker management system, and in regards to updating I can just hit a “Recreate” button and select “re-pull image” to update them. As long as you have the containers tied to persistent data folders it just pulls the latest image and ““re-installs”” it per your docker-compose file and everything is just as you left it.
Do you need to recreate the container? Can you update the applications in the container?
I mean, I know I don’t have to recreate it when I use a normal container, but I’m not clear when using compose
Hopefully someone with knowledge can weigh in.

That makes sense
