# Run with docker compose up with provinding DBUSER, DBPASS and SecretKey(Optnl). 
# You can also pass in .env file just create. env file in directory
# If you run into error just cancel and run docker compose up, it may error out in build or docker compose up just rerun the command
# I think it is due to  connection error between postgres and webapp.
