is there a way to launch a container when a page is called?

[Betonhaus]

I figured I'd ask here. I have a docker app that has a tendancy to eventually crash after running for a while. I'm poking the developer about it but haven't made any progress.

What I'm wondering is if there's some sort of "launch on load" thing?

1. open the web url associated with the app, which npm or a 3rd party monitors instead
2. npm or a third party component restarts the app's docker image, and ensures it loads
3. npm or 3rd party proxies the app so that it loads from that url

ideally npm or the 3rd party would offer a login page (optional), be able to detect if the app is responding or not, and if it isn't pull up a loading page while it forces the app to restart
