Angular app show different UI between local & production environment

Question

I am using Angular 5 and Node.js.

I don't know how on earth this would happen, but I notice my local environment is displaying different look than the one that I deployed via DockerCloud.

This is my

package.json

{
  "name": "web",
  "version": "0.0.0",
  "license": "MIT",
  "scripts": {
    "ng": "ng",
    "start": "ng serve --port 4202",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },

    "@angular/router": "5.0.3",

  },
  "devDependencies": {

    "protractor": "~5.1.2",
    "ts-node": "~3.2.0",
    "tslint": "~5.7.0",
    "typescript": "~2.4.2"
  }
}

This is my

web.dockerfile

### STAGE 1: Build ###
FROM node:9.3.0-alpine as builder

COPY package.json ./

RUN npm set progress=false && npm config set depth 0 && npm cache clean --force

## Storing node modules on a separate layer will prevent unnecessary npm installs at each build
RUN npm i
RUN mkdir /web
RUN cp -R ./node_modules ./web

WORKDIR /web

COPY . .

## Build the angular app in production mode and store the artifacts in dist folder
RUN $(npm bin)/ng build --prod --build-optimizer

### STAGE 2: Setup ###

FROM nginx:1.13.8-alpine

COPY nginx.conf /etc/nginx/nginx.conf
COPY site.conf /etc/nginx/conf.d/default.conf
RUN rm -rf /usr/share/nginx/html/*

COPY --from=builder /web/dist /usr/share/nginx/html/

RUN touch /var/run/nginx.pid && \
  chown -R nginx:nginx /var/run/nginx.pid && \
  chown -R nginx:nginx /var/cache/nginx && \
  chown -R nginx:nginx /usr/share/nginx/html

USER nginx

Result

Is it because of some kind of version different of some packages?

Answer 1

had the same issue and solved it by adding --extract-css=false to my build command
