Frustrating experience with installation for remote DB

Have tried to install ERPNext over this weekend, but I am going no where so far. I try to install by Docker image except DB. For the DB, I have to use my company’s network DB (say 192.168.255.255).

Unlike Discourse, it seeems like I have to add extra values to use remote DB, in addition to different IP/host. I keep getting internal server error.

Thought it would be as simple as Discourse that I just change yml values for website url, DB IP/port, and additional apps. It doesn’t work so far.

Any detailed documents available for yml parameters for installation?

Though I do appreciate the support forum and the documents for installation options, almost none of them helped me. In the end, I just copy and pasted pwd.yml with custom built image. There were only handful of options in parameters, so I did all custom settings within the docker.

I just hope that I dont have to frequently re compose my docker containers.
