Docker container doesn't reload Angular app

Question

I have some issue with ng serve in my docker container running by docker-compose.

Dockerfile

FROM node:7.1

RUN mkdir -p /u         


        

Answer 1

A solution can be the chokidar wrapper, which is a dependency of the angular package. I dont know, if that was the status in 2017. You don't need to expose any extra ports. Just use an environment variable in your docker-compose.

Basic configuration:

Dockerfile

CMD ng serve --host 0.0.0.0

docker-compose.yml

environment:
  - CHOKIDAR_USEPOLLING=true

This should hot-reloading your browser. Tested on Chrome and Angular 8
