Hi Ajkuma,
Thankfully I've resolve this issue, but I'm posting this for the next person who stumbles on this problem.
The problem I was receiving was "docker container could not be started: zoompic_0_54831544", I believe it was trying to ping to another page which wouldn't allow my page to start.
In order to resolve this problem I followed this website "https://learn.microsoft.com/en-au/azure/app-service/configure-custom-container?pivots=platform-linux"and found that this command "az webapp config appsettings set --resource-group <resource-group-name> --name <app-name> --settings WEBSITES_PORT=8000" saved my code, and my app is now up and running properly.
Just want to give a huge shoutout to the MSFT team, because they were very patient and helpful along the way, without them I would've never been able to get this far!
