I have the following `docker-compose.yml` file to build me 2 services. It starts up and runs perfectly. The problem is that if I execute an ember command in the container, it creates the files but when I edited them in VS code and hit save, I get permission denied. How can I fix this? 

```
version: '3'

volumes:
  ember-bower_components:
  ember-node_modules:

services:
  ember:
    build: .
    container_name: cf2-ember
    ports:
      - 7357:7357
      - 4200:4200
      - 9222:9222
      - 49152:49152
    volumes:
      - .:/myapp
      - ember-bower_components:/myapp/bower_components
      - ember-node_modules:/myapp/node_modules
      - ./docker/entrypoint.sh:/entrypoint.sh
    tmpfs:
      - /myapp/tmp
    environment:
      - APIM_HOST=CHANGEME
      - APIM_SUBSCRIPTION_KEY=CHANGEME
    command: ["sh", "/entrypoint.sh"]
  nginx:
    image: nginx:1.12.1-alpine
    container_name: cf2-nginx
    ports:
      - 8081:8080
    depends_on:
      - ember
    volumes:
      - ./docker/default.template:/etc/nginx/conf.d/default.template
      - ./dist:/usr/share/nginx/html:delegated
    environment:
      - SERVER_NAME=localhost
    command: /bin/sh -c "envsubst < /etc/nginx/conf.d/default.template > /etc/nginx/conf.d/default.conf && nginx -g 'daemon off;'"

```
