my current Dockerfile:

# Stage 1: Install dependencies and build the app
FROM node:18-alpine AS builder
WORKDIR /app

COPY package*.json ./
RUN npm install

COPY . .
RUN npm run build

# Stage 2: Run the app
FROM node:18-alpine
WORKDIR /app

COPY --from=builder /app/node_modules ./node_modules
COPY --from=builder /app/.next ./.next
COPY --from=builder /app/public ./public
COPY --from=builder /app/package*.json ./

CMD ["npm", "run", "dev"]

My current docker-compose.yaml

version: "3.5"

services:
  app:
    build:
      context: .
      dockerfile: Dockerfile
    container_name: next-ui
    ports:
      - "3000:3000"
    volumes:
      - .:/app
    env_file:
      - .env.local

the image size is aroud 500mb for me, I have looked into pages router docker image and it goes down to 150mb I didn't find a docker file for app router. How do I optimise my current image so it doesnt take up too much space?
