Я создаю многоэтапный образ докера для проекта, который использует nextjs и preact в монорепозитории lerna.
Однако многоэтапная сборка выполняется успешно, когда я хочу запустить образ, nextjs выдает ошибку, что «реакция» не может быть найдена.
Dockerfile для многоэтапной сборки:
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 ${PORT}
В финале я убедился, что модуль react был скопирован в папку node_modules. Сам модуль реакции просто использует псевдоним для использования preact/compat.
При запуске всего в одном билдере все работает отлично:
FROM node:12 as builder
RUN curl -sfL https://install.goreleaser.com/github.com/tj/node-prune.sh | bash -s -- -b /usr/local/bin
RUN npm -g config set user root && \
npm install -g lerna
WORKDIR /app
COPY . ./
ARG TARGET_APP_FOLDER=apps/app-1
# Install dependencies
COPY yarn.lock ./
WORKDIR /app/${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 ${PORT}
Починил это!
Это файл докеров, который я использую прямо сейчас на случай, если кто-то наткнется на ту же проблему:
FROM node:12-alpine AS base
# DEFAULT ARGS
ENV BUILD_FOLDER=/build
ENV TARGET_APP_FOLDER=/apps/my_app
# CHECK PROJECT ID IS SET
ARG PROJECT_ID
RUN test -n "$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}
