Setup Nextjs Docker Deploy Ke Fly.io

Setup nextjs dengan docker untuk Deploy ke Fly.io, karena sangat cepat dan andal

Buat Project dengan Nextjs :

yarn create next-app nextfly

Lalu ubah next.config.js

const nextConfig = {
  reactStrictMode: true,
  // config output akan menjelaskan ke nextjs bahwa akan menggunakan docker
  output: 'standalone',
};
module.exports = nextConfig;

dan Buat file Dockerfile seperti ini

# Install dependencies only when needed
# Dockerfile
FROM node:16-alpine AS deps
RUN apk add --no-cache libc6-compat
WORKDIR /app
COPY package.json yarn.lock ./
RUN yarn install --frozen-lockfile


FROM node:16-alpine AS builder
WORKDIR /app
COPY --from=deps /app/node_modules ./node_modules
COPY . .

ENV NEXT_TELEMETRY_DISABLED 1
ARG NEXT_PUBLIC_API_URL

RUN yarn build

FROM node:16-alpine AS runner
WORKDIR /app


ENV NODE_ENV production
ENV NEXT_TELEMETRY_DISABLED 1

RUN addgroup --system --gid 1001 nodejs
RUN adduser --system --uid 1001 nextjs

COPY --from=builder /app/next.config.js ./
COPY --from=builder /app/public ./public
COPY --from=builder /app/package.json ./package.json

COPY --from=builder --chown=nextjs:nodejs /app/.next/standalone ./
COPY --from=builder --chown=nextjs:nodejs /app/.next/static ./.next/static

USER nextjs

EXPOSE 3000

ENV PORT 8080

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

dan deploy dengan perintah :

flyctl deploy
