NextJS 应用使用 docker 自托管部署

发布于

Vercel 用起来是真方便，免运维 + github 提交自动触发 CI/CD，确实太香了，但国内直接被墙了没办法呀， 只好自己买个云服务器托管了，第一想法就是 docker 部署了，原来的模板代码1是没有集成 docker 构建的，因此自己找到了官方提供的示例， 试用发现跑不起来，然后手动改了一点

Dockerfile
FROM node:18-alpine AS base

# Rebuild the source code only when needed
FROM base AS builder
# Check https://github.com/nodejs/docker-node/tree/b4117f9333da4138b03a546ec926ef50a31506c3#nodealpine to understand why libc6-compat might be needed.
RUN apk add --no-cache libc6-compat

WORKDIR /app
COPY . .
RUN yarn install && yarn run build

# Production image, copy all the files and run next
FROM base AS runner
WORKDIR /app

ENV NODE_ENV=production
# Uncomment the following line in case you want to disable telemetry during runtime.
# ENV NEXT_TELEMETRY_DISABLED=1

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

COPY --from=builder /app/public ./public

# Set the correct permission for prerender cache
RUN mkdir .next
RUN chown nextjs:nodejs .next

# Automatically leverage output traces to reduce image size
# https://nextjs.org/docs/advanced-features/output-file-tracing
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=3000

# server.js is created by next build from the standalone output
# https://nextjs.org/docs/pages/api-reference/next-config-js/output
ENV HOSTNAME="0.0.0.0"
CMD ["node", "server.js"]

目前在服务器上拉完代码后构建镜像然后应用跑在 docker 里，再用 nginx 反向代理到网站，整个流程在 1panel 里操作还是非常方便的，后面考虑 jenkins 自动化了
