【问题描述】：

我在 next.js 上使用 yarn berry。我需要减少这个构建的 docker 镜像大小，所以我转换为基于 next.js 的独立构建。

这是我的 Dockerfile。

FROM node:16-alpine as builder

WORKDIR /app

COPY package.json ./
COPY yarn.lock ./
COPY .pnp.cjs ./
COPY .pnp.loader.mjs ./
COPY .yarnrc.yml ./
COPY .yarn .yarn
RUN yarn install --immutable

COPY . .

ARG GITHUB_SHA=0
RUN yarn build

FROM node:16-alpine AS runner

WORKDIR /app

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

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

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

ENV NODE_ENV='production'
CMD node server.js

它可以构建命令docker build -t standalone . 然后我可以获得输出图像。

当我使用命令docker run -d -p3000:3000 standalone 运行这个 docker 镜像时。

我收到这个错误。
