Cara Menjalankan Aplikasi Next.js di VPS Menggunakan Docker & Docker Compose

Prasyarat

Pastikan sebelum memulai:

• VPS Linux (Ubuntu 20.04 / 22.04 / 24.04 direkomendasikan)
• Docker & Docker Compose sudah terinstal
• Source code Next.js siap digunakan
• Aplikasi dapat berjalan normal di lokal

1. Dockerfile Next.js (Production)

Gunakan multi-stage build agar image lebih kecil, aman, dan cepat.

FROM node:20-alpine AS builder

WORKDIR /app

COPY package*.json ./
RUN npm install

COPY . .
RUN npm run build

FROM node:20-alpine AS runner

WORKDIR /app
ENV NODE_ENV=production

COPY --from=builder /app/.next/standalone ./
COPY --from=builder /app/.next/static ./.next/static
COPY --from=builder /app/public ./public

EXPOSE 3000

CMD ["node", "server.js"]

2. Konfigurasi Docker Compose

version: "3.9"

services:
  nextjs:
    build: .
    container_name: nextjs-app
    restart: always
    ports:
      - "127.0.0.1:3001:3000"
    environment:
      NODE_ENV: production

3. Build dan Jalankan Aplikasi

docker compose build
docker compose up -d

Cek container:

docker ps

4. Pengujian Aplikasi

curl http://127.0.0.1:3001

5. Struktur Direktori
