node.js - 在Docker中构建Angular会抛出 “environment.prod.ts path in file replacements does not exist”

Question

当我尝试构建以下Dockerfile时，将引发错误。
我也尝试使用RUN命令来全局安装angular / cli并直接用另一个RUN ng build --prod调用，但是会发生相同的错误。

Dockerfile

FROM node:12.17.0-alpine AS build-angular
WORKDIR /src
COPY webui/* webui/
WORKDIR /src/webui
RUN ["npm", "install"]
RUN ["npm", "run", "build"]

构建错误输出

Step 6/6 : RUN ["npm", "run", "build"]

来自angular.json的摘录

"production": {
              "fileReplacements": [
                {
                  "replace": "src/environments/environment.ts",
                  "with": "src/environments/environment.prod.ts"
                }
              ],

我必须从COPY行中删除*。
以下DOCKERFILE起作用:

FROM node:12.17.0-alpine AS build-angular
WORKDIR /src
COPY webui ./
RUN ["npm", "install"]
RUN ["npm", "run", "build"]

如Dockerfile reference中所述，不需要*

If is a directory, the entire contents of the directory are copied, including filesystem metadata.
