It would be much helpful if you provide docker-compose.yml or kubernetes deployment yaml.

Getting this error when attempting to use pyodbc in my django application. When I ssh into the container I am able to use sqlcmd to execute queries using the same connection string as my app is using. I've seen that this might be a permissions issue however I have configured everything to run as root and am still seeing this issue.

Stack Trace:
