Issue while running image of emoncms-docker

I installed the Docker image of Emoncms from the following Github branch:

After completing the installation, when I tried to open it on the server, It gave the following error:

" Can’t connect to the database, please verify credentials/configuration in settings.ini
Error message: Access denied for user ‘emoncms’@‘172.18.0.5’ (using password: YES) "

Please suggest further steps for successfully running the Docker Image.
