Hi!
I have relatively simple application written in Nest JS and using Postgres as DB.
All that is containerized with Docker, i have two Dockerfile’s (dev and prod). Also docker-compose file for managing multiple containers. I was following this article to figure out how to deploy my service with docker-compose and Koyeb.
It worked, but partially, looks like the DB services are starting, but the Nest application not 
This is a bit unexpected.
Here are my files
Dockerfile.koyeb:
FROM koyeb/docker-compose
COPY . /app
Dockerfile.prod:
FROM node:22-alpine as build
# Working directory inside the container
WORKDIR /code
# Copy package.json and package-lock.json
COPY package*.json ./
COPY tsconfig.json ./
# Install dependencies
RUN npm install
# Copy the application code
COPY . .
# Build the application
RUN npm run build
# Production Stage
FROM node:22-alpine AS production
# Working directory inside the container
WORKDIR /app
COPY --from=build /code/dist ./dist
COPY --from=build /code/node_modules ./node_modules
COPY package*.json ./
EXPOSE 8080
# Start the application
CMD ["npm", "run", "start:prod"]
docker-compose.yml
services:

All files are in root directory. And in the screenshot you can see my settings inside Koyeb service
