I'm building the angular6 app w/ a docker multistage build.
The default angular.json created by angular.cli contains a build section including a list of configurations.
I can select a specific configuration using the following command

ng build --configuration production 

but in my docker multistage build I cannot us ng directly but npm only

using "npm run build" kicks "ng build" but I don't know how to supply the additional parameters "--configuration production" to select a specific configuration.

That's a chunck of my angular.json file

{

  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",

  "version": 1,

  "newProjectRoot": "projects",

  "projects": {

    "woa-angular6-app": {

                {

                  "with": "src/environments/environment.prod.ts"

                }

              ],

            }

          }

        },

        "serve": {...

that's my dockerfile

# Stage 1

FROM node:8.11.2-alpine as node



WORKDIR /usr/src/app



COPY package*.json ./



RUN npm install



COPY . .



# how to supply the equivalent parameter to select a given configuration?

RUN npm run build 

#RUN ng build --configuration production



# Stage 2

FROM nginx:1.13.12-alpine



COPY --from=node /usr/src/app/dist/woa-angular6-app /usr/share/nginx/html



COPY ./nginx.conf /etc/nginx/conf.d/default.conf

Default build production for angular

ng build --prod --build-optimizer

read more here https://angular.io/guide/deployment

Not sure I understand what you trying to do, but in package json, you can create the run command as you wish per environment like

"scripts": {

  "build:production": "ng build --prod ... + your prod config flags here",

  "build:staging": "ng build --prod ... +  whatever flags",

  "build:dev": "ng build --prod + whatever flags",

}

Check what options you can provide here :

https://angular.io/cli/build

Then from docker file you just

npm run build:production

Hope this helps!
