Problem when I dockerize my Angular application

My problem is that I cna't see my application on the broswer (http://localhost:1999/), My docker command are this: docker-compose build docker-compose up

I'm doing something wrong? Why can't I see my application running? I tried to add the CMD line with ng -serve but it give me the error that ng isn't istalled, any other suggest?

My docker console:

/docker-entrypoint.sh: /docker-entrypoint.d/ is not empty, will attempt to perform configuration
/docker-entrypoint.sh: Looking for shell scripts in /docker-entrypoint.d/
/docker-entrypoint.sh: Launching /docker-entrypoint.d/10-listen-on-ipv6-by-default.sh

My Dockerfile:

FROM node:latest as node
WORKDIR /app
COPY . .
RUN npm install
RUN npm run build --prod
EXPOSE 1999
#stage 2
FROM nginx:alpine
COPY --from=node /app/dist /usr/share/nginx/html

My docker-compose:

version: "3.8"

  db:
    image: mongo:latest
    ports:

    environment:

    volumes:

  web:
    build: ./PersonBE/src/main/resources/person-fe
    ports:

  api:

You are using a multistage build. The port exposed is the nginx port (80) not the node port 1999 (the line EXPOSE 1999 is useless here)

Try :

[...]
  web:
    build: ./PersonBE/src/main/resources/person-fe
    ports:
      - 80:80 # port mapping like the command "docker run -d 80:80 person-fe:latest" will do
[...]

Next open : http://localhost:80 or http://localhost

Also, your app is generated in the /app/dist/person-fe so you must COPY the content of this folder in nginx folder with COPY --from=node /app/dist/person-fe /usr/share/nginx/html :

FROM node:latest as node
WORKDIR /app
COPY . .
RUN npm install
RUN npm run build --prod
EXPOSE 1999
#stage 2
FROM nginx:alpine
COPY --from=node /app/dist/person-fe /usr/share/nginx/html
