Question

我试图通过运行

docker compose up

来对项目进行 dockerize，但显示了此错误。

这是 Dockerfile

FROM node:gallium-alpine3.18 as build
WORKDIR /app
COPY package.json .
COPY package-lock.json .
RUN npm install
COPY . .
RUN npm run install-all

# Stage 2
FROM nginx
WORKDIR /usr/share/nginx/html
RUN rm -rf ./*
RUN echo ${PWD} && ls -la
COPY --from=build /app/build .
ENTRYPOINT ["nginx", "-g", "daemon off;"]

这是

docker-compose.yml

version: '3.8'

services:
  app: 
    container_name: product_container
    image: product_image
    build:
      context: .
    ports:
      - 8000:8000

以下是可通过

npm run

获得的脚本

install-all
    cd server && npm i && cd .. && cd client && npm i
  server
    cd server && npm start
  server-dev
    cd server && npm run dev
  client-dev
    cd client && vite
  client-build
    cd client && vite build
  client-preview
    cd client && vite preview

我什至尝试将

COPY --from=build /app/build .

更改为

COPY --from=build /app/install-all

以防万一，但我遇到了同样的错误。

Answer 1

确保

.dockerignore

不包含

/app/build

。
