-#!/bin/bash
-# Stop the running backend
-docker stop modocot-backend

-# Delete the existing container
-docker rm modocot-backend
-
-# Pull the new version from DockerHub
-docker pull hftstuttgart/modocot-backend
-
-# Build the container and start it
-docker run --name modocot-backend -p 8888:8081 hftstuttgart/modocot-backend:latest &
