构建 docker 映像时，React 应用构建失败

Question

I am trying to dockerize a react application, but npm run build layer is failing and giving this error: Dockerfile

FROM node:16-alpine

WORKDIR /app/app-v2

COPY .npmrc ./

COPY package.json ./

RUN npm install --legacy-peer-deps

COPY . .

RUN npm run build:qa

RUN rm -r node_modules

# CMD ["npm", "run", "start:dev"]

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

I'm facing error on build layer.

 => ERROR [7/8] RUN npm run build:qa                                                                                     292.8s

Error I'm using node v16 and npm v8

Seems your server does not have enough system memory to build your project. In general, I would recommend 1GB memory on your vps or if using a windows OS then it depends on the version. It would be helpful to provide the amount of memory available on your host. Some reference on docker system requirements: Docker requirements
