i am trying to containerize my nextjs application but I always encounter a series of problems.

I want my container to connect to an external database so I first create networks:... and add it in my web but after building and running the container I got an error of Can't reach database server at SERVER_IP_ADD:1433. So I tried to remove the networks:.. but I got an error of Error opening a TLS connection: The TLS settings didn't allow the connection to be established. Please review your connection string.. Can anyone point out my mistake? Is it in Dockerfile or docker-compose? my application is working fine when I run npm run dev
networks:, and manually specifying IP addresses in Docker is rarely if ever necessary. I don't see the database listed in your Compose setup; where is it actually running? If the connection is over TLS, do you need to use a host name (not an IP address) that matches the server certificate? Do you need to load a custom CA certificate?
