Dockerizing Angular 应用程序时的问题

Question

我对 docker 和 angular 非常陌生，我收到错误 index.html generation failed while builidng docker image 谁能帮我解决 index.html generation failed 错误，或者如果我的 dockerfile 中有任何错误，请纠正我。

Docker 文件

 FROM node:latest AS builder
 WORKDIR /csswebdockerimage
 COPY . .
 RUN npm i
 RUN npm run build --prod

 FROM nginx:alpine
 COPY --from=builder /csswebdockerimage/dist/cssweb-demo1/ /usr/share/nginx/html
 # EXPOSE 80
 # CMD ["nginx","-g"]

package.json

{
   "name": "cssweb-demo",
     "version": "0.0.0",
       "scripts": {

Answer 1

不知道这是否能解决问题，但这是我对 Angular 进行 dockerize 的方式

FROM node:12-alpine
LABEL Author="okira-e"

COPY package*.json ./
RUN npm install -g @angular/cli
RUN npm install

RUN mkdir src
WORKDIR /src

COPY . .

EXPOSE 4200

你可以尝试先复制 package.json 并在复制当前目录中的所有文件之前安装所有包，像这样

Dockerfile

FROM node:12.7-alpine AS builder
WORKDIR /csswebdockerimage
COPY package.json ./
RUN npm cache clean --force
RUN npm i
COPY . .
RUN node_modules/.bin/ng build --prod --aot --build-optimizer --vendor-chunk=true


FROM nginx:1.19.0-alpine
VOLUME /var/cache/nginx
COPY --from=builder /csswebdockerimage/dist/cssweb-demo1/ /usr/share/nginx/html
COPY ./.config/.nginx/nginx.conf /etc/nginx/conf.d/default.conf
EXPOSE 80
