Could you share your Dockerfile, and docker-compose.yml?

Sure :
Here is my DockerFile :

FROM node:20.10.0

# Set the working directory in the container
WORKDIR /usr/src/app

# Copy package.json and package-lock.json (or yarn.lock)
COPY package*.json ./

# Install app dependencies
RUN npm ci

# Bundle app source inside the Docker image
COPY . .

# Rebuild bcrypt for the current platform
RUN npm rebuild bcrypt --build-from-source

# Build the application
RUN npm run build

# Your app binds to port 3000 (or the port your app uses)
EXPOSE 3000

# Define the command to run your app (adjust as necessary based on your npm scripts)
CMD ["npm", "run", "start:dev"]
#

and My docker-compose.yml:

version: '3.8'

services:
  # PostgreSQL Database Service
  postgres:
    image: postgres:latest
    ports:
      - "5432:5432"
    environment:
      POSTGRES_USER: username     
      POSTGRES_PASSWORD: password 
      POSTGRES_DB: erd   
    volumes:
      - postgres-data:/var/lib/postgresql/data

  # NestJS Backend Service

      KONG_DECLARATIVE_CONFIG: /etc/kong/kong.yml
    ports:
      - "8000:8000" #HTTP TRAFFIC
      - "8443:8443" #HTTPS

      - "8444:8444"
    depends_on:
      - nestjs-backend
    volumes:

    command: ["kong", "start", "--vv"]


volumes:

Thanks for your help!

Adding those volume binds to my docker-compose.yml did the trick.

it was exactly what I needed to solve this issue.
