Files not getting stored properly in Azure File Share

Question

Hello Experts,

I have deployed a docker container as a web app. If I use WEBSITES_ENABLE_PERSISTENT_APP_STORAGE the data gets stored in the app storage. However, I want to use Azure File Share for better results.

My container basically is a database application that uses XAMPP server. The database files are stored in the location: /opt/lampp/var/mysql in the case of my container which uses Ubuntu.

The contents of this directory are as follows:

a214daf4f291.err a214daf4f291.pid aria_log.00000001 aria_log_control
ib_logfile0 ib_logfile1 ibdata1 ibtmp1 multi-master.info
mysql mysql.sock performance_schema phpmyadmin test

where the last lines correspond to folders.

I am able to connect to the file share, but the result is as follows:

I am not able to figure out why all files and folders inside the mysql directory are not getting stored in the Azure file share. I deployed the web app using a docker compose file as follows:

----------

version: '3.3'

services:
db:
image: testosreg.azurecr.io/webimage
volumes:
- db-data:/opt/lampp/var/mysql

volumes:
db-data:

----------

where db-data is the name of the Azure Storage Mount for the web app.

I followed this video for deploying the web app: https://www.youtube.com/watch?v=q7J050yovuo

Any help or suggestions in this regard?
