Docker 和 Flutter Web 热重载

如何解决Docker 和 Flutter Web 热重载

我正在尝试使用 docker compose 在 docker 中使用 Flutter 构建 Web 开发环境。 我坚持对 Flutter 进行热重载，有什么办法可以让它工作吗？ （在 Flutter docker 机器上安装 VSCode 除外）

这是我的 Dockerfile for Flutter 的样子：

#Stage 1 - Install dependencies and build the app
FROM debian:latest AS dev
workdir /root

# Install Flutter dependencies
RUN apt-get update 
RUN apt-get install -y curl git wget unzip libgconf-2-4 gdb libstdc++6 libglu1-mesa fonts-droid-fallback lib32stdc++6 python3
RUN apt-get clean

# Clone the Flutter repo
RUN git clone https://github.com/Flutter/Flutter.git /usr/local/Flutter

# Set Flutter path
# RUN /usr/local/Flutter/bin/Flutter doctor -v
ENV PATH="/usr/local/Flutter/bin:/usr/local/Flutter/bin/cache/dart-sdk/bin:${PATH}"

# Run Flutter doctor
RUN Flutter doctor -v
# Enable Flutter web
RUN Flutter channel master
RUN Flutter upgrade
RUN Flutter config --enable-web

# copy files to container and build
workdir /root
copY . .
RUN Flutter build web

# Stage 2 - Create the run-time image
FROM Nginx
EXPOSE 3000
copY --from=dev /root/build /usr/share/Nginx/html

copY Nginx.conf /etc/Nginx/Nginx.conf

还有docker-compose：

version: '3.8'
services:
  # back-end api built with golang
  golang:
    build: 
      context: golang
      target: dev
    volumes:
      - ./golang:/root
    ports:
      - "5000:5000"
    env_file: .env
    depends_on:
      - db

  # front-end built with react
  Flutter:
    build: 
      context: Flutter
      target: dev
    restart: always
    volumes:
      - ./Flutter:/root
    ports:
      - "3000:3000"
    command: >
            sh -c "Flutter pub get && Flutter run -d web-server --web-port 3000 --web-hostname 0.0.0.0"

  # postgres is our primary data store
  db:
    build: db
    volumes:
      - ./db/migrations:/docker-entrypoint-initdb.d/migrations

  # Nginx is used for ssl termination
  Nginx:
    build: 
      context: Nginx
      target: dev
    ports:
      - "443:443"
    depends_on:
      - Flutter
      - golang
