运行 multi-stacker docker 构建的 docker 镜像失败 – Nexts 找不到反应模块

如何解决运行 multi-stacker docker 构建的 docker 镜像失败 – Nexts 找不到反应模块

我正在为一个使用 nextjs 并在 lerna monorepo 中进行 preact 的项目构建一个多阶段 docker 映像。

多阶段构建成功，但是，当我想运行图像时，nextjs 抛出一个错误，说找不到 'react'。

用于多阶段构建的 Dockerfile：

FROM node:12 as builder

RUN curl -sfL https://install.goreleaser.com/github.com/tj/node-prune.sh | bash -s -- -b /usr/local/bin

RUN npm -g config set user root && \
    npm install -g lerna

WORKDIR /app
COPY . ./

ARG TARGET_APP_FOLDER=apps/app-1

# Install dependencies
COPY yarn.lock ./
WORKDIR /app/${TARGET_APP_FOLDER}
RUN lerna bootstrap \
    -- --production

# Build
ARG PROJECT_ID
RUN test -n "$PROJECT_ID" || (echo "PROJECT_ID not set. Need to set PROJECT_ID to the GCP project ID you're deploying to" && false)

ENV PROJECT_ID=${PROJECT_ID}
RUN yarn run build:prod && \
    /usr/local/bin/node-prune

# Our final image
FROM node:12-alpine

RUN yarn global add next

ARG TARGET_APP_FOLDER=apps/app-1

WORKDIR /app

# copy from build image
COPY --from=builder /app/node_modules ./node_modules
COPY --from=builder /app/${TARGET_APP_FOLDER}/.next ./.next
COPY --from=builder /app/${TARGET_APP_FOLDER}/node_modules ./node_modules
COPY --from=builder /app/${TARGET_APP_FOLDER}/package.json ./package.json

ENV PORT=8080
CMD yarn run start -p ${PORT}

我在决赛中验证了 react 模块已复制到 node_modules 文件夹中。 react 模块本身只是使用别名来使用 preact/compat。

在单个构建器中运行所有内容时，它工作得非常好：

FROM node:12 as builder

RUN curl -sfL https://install.goreleaser.com/github.com/tj/node-prune.sh | bash -s -- -b /usr/local/bin

RUN npm -g config set user root && \
    npm install -g lerna

WORKDIR /app
COPY . ./

ARG TARGET_APP_FOLDER=apps/app-1

# Install dependencies
COPY yarn.lock ./
WORKDIR /app/${TARGET_APP_FOLDER}
RUN lerna bootstrap \
    -- --production

# Build
ARG PROJECT_ID
RUN test -n "$PROJECT_ID" || (echo "PROJECT_ID not set. Need to set PROJECT_ID to the GCP project ID you're deploying to" && false)

ENV PROJECT_ID=${PROJECT_ID}
RUN yarn run build:prod && \
    /usr/local/bin/node-prune

# Start the server
ENV PORT=8080
CMD yarn run start -p ${PORT}

解决方法

修复它！

这是我现在正在使用的 dockerfile，以防有人遇到同样的问题：

FROM node:12-alpine AS base

# DEFAULT ARGS
ENV BUILD_FOLDER=/build
ENV TARGET_APP_FOLDER=/apps/my_app

# CHECK PROJECT ID IS SET
ARG PROJECT_ID
RUN test -n "$PROJECT_ID" || (echo "PROJECT_ID not set. Need to set PROJECT_ID to the GCP project ID you're deploying to" && false)
ENV PROJECT_ID=${PROJECT_ID}
