Angular 通用 Docker 构建问题

Question

When I'm trying to build my Docker file, I'm getting the below error

ERROR in Cannot read property '0' of undefined

npm ERR! code ELIFECYCLE

npm ERR! errno 1 npm

ERR. ssf@0.0:0 build:ssr: ng build --prod && ng run ssf:server:production npm ERR! Exit status 1

Please find below my Docker file

FROM node:10.16.3-slim AS build
WORKDIR /app
COPY ./package.json ./package-lock.json /app/
RUN npm install
COPY . /app
ENV NODE_OPTIONS --max-old-space-size=4096
RUN npm run build:ssr **(Error is coming at this line)**
COPY --from=build /app/package.json /app
COPY --from=build /app/dist /app/dist
EXPOSE 4000
ENV NODE_ENV production
CMD ["npm", "run", "serve:ssr"]

Also, this is the package.json snapshot

{
  "name": "ssf",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e",
    "dev:ssr": "ng run ssf:serve-ssr",
    "serve:ssr": "node dist/server/main.js",
    "build:ssr": "ng build --prod && ng run ssf:server:production",
    "prerender": "ng run ssf:prerender"
    
  },

I'm not sure if this is still relevant.. but you can try replacing your dockerfile with the following:

### Stage: 1 ###
FROM node:14-alpine as Build
WORKDIR /app
COPY ./package.json ./package-lock.json /app/
RUN npm install
COPY . /app
#This will create dist/ and dist-server/ folders in docker
RUN npm run build:ssr

### Stage: 2 ###
FROM node:14-alpine
WORKDIR /app
COPY --from=Build /app/package.json /app
COPY --from=Build /app/dist /app/dist
COPY --from=Build /app/dist/server /app/dist-server

EXPOSE 4000

CMD ["npm", "run", "serve:ssr"]

I'm still testing this myself but I successfully run this container already. Hope this will help you or others reading this.

Kind regards, R
