【问题描述】:
我正在按照本指南将 Docker 支持添加到我现有的 NextJS + TypeScript 项目并部署到 Google Cloud Run:https://github.com/vercel/next.js/tree/canary/examples/with-docker。
但是,构建您的容器步骤:
docker build -t nextjs-docker .
一直失败,因为它给了我一个错误“stat app/.next/standalone:文件不存在”错误。
我查看了我的 .next 文件夹并且没有生成独立文件,这就是我收到该错误的原因。如何创建这个 .next/standalone 文件?
我的 next.config.js 文件如下所示:
module.exports = {
eslint: {
ignoreDuringBuilds: true,
},
experimental: {
outputStandalone: true
}
}
我的 Dockerfile 看起来像这样:
# Install dependencies only when needed
FROM node:16-alpine AS deps
RUN apk add --no-cache libc6-compat
WORKDIR /app
COPY package.json package-lock.json tsconfig.json ./
RUN npm ci
# Rebuild the source code only when needed
FROM node:16-alpine AS builder
WORKDIR /app
COPY --from=deps /app/node_modules ./node_modules
COPY . .
RUN npm run build
# Production image, copy all the files and run next
FROM node:16-alpine AS runner
WORKDIR /app
ENV NODE_ENV production
RUN addgroup --system --gid 1001 nodejs
RUN adduser --system --uid 1001 nextjs
# You only need to copy next.config.js if you are NOT using the default configuration
COPY --from=builder /app/next.config.js ./
COPY --from=builder /app/public ./public
COPY --from=builder /app/package.json ./package.json
# Automatically leverage output traces to reduce image size
# https://nextjs.org/docs/advanced-features/output-file-tracing
# Following line is giving me the error
# NOTE: I can not just comment out this line because it will give an error later that \"Cannot find module \'/app/server.js\"
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
CMD [\"node\", \"server.js\"]
我的 .next 文件夹如下所示:
- .next
- cache
- server
- static
- traces
- BUILD_ID
- build-manifest.json
- export.marker.json
- images-manifest.json
- prerender-manifest.json
- react-loadasble-manifest.json
- required-server-files.json
- routes-manifest.json
- trace
我的理解是添加:
experimental: {
outputStandalone: true
}
到 next.config.js 文件,然后运行 npm run build 将创建 .next/standalone 文件,但似乎无法正常工作。
