Containers custom build

so in the base containers config they simply reference a dockerfile like this: https://github.com/cloudflare/templates/blob/main/containers-template/wrangler.jsonc#L13 that's not ideal for my project because: 1. I want to build the containers myself...

My service is failing to respond with the error Container suddenly disconnected, try again being returned. When I look at the worker logs it shows a 500 error in the fetch but when I look at the container logs it shows it responded to the request with a 200 OK. Everything works perfectly running locally w/ wrangler dev but fails in production (though this same service did work yesterday).
