Docker容器不会重新加载Angular应用 [英] Docker container doesn't reload Angular app

问题描述

我在由docker-compose运行的docker容器中的ng serve出现了一些问题.

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

Dockerfile

Dockerfile

FROM node:7.1

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY package.json /usr/src/app
RUN npm install
RUN npm install -g angular-cli
COPY . /usr/src/app

EXPOSE 4200

CMD [ "npm", "start" ]'

还有我的docker-compose.yml

And my docker-compose.yml

web:
    build: .
    ports:
        - '8089:4200'
    volumes:
        - .:/usr/src/app/
    environment:
        - NODE_ENV=dev
    command: bash -c "npm start"

当我运行它时，一切都很好，但是编辑文件不会增加应用程序的重载.文件已更改，我确定是因为我通过ssh连接对其进行了检查，并且容器中的文件已被编辑.再次重新启动容器后，将应用所有更改. 我以为，当我仅通过泊坞窗切换建筑物的图像来构成此图像时，它就会消失，但不会消失.

Everything works great when I run it but the editing file does not rise reload of application. File is changed, I'm sure because I check it by ssh connection and the file in the container is edited. When container is restarted again every change is applied. I thought when I switch with building image by only docker to compose this will disappearr, but do not.

当我打电话时，请触摸docker exec webpack中的某些文件，重新加载所有文件，这样就可以在不重新启动容器的情况下正常工作.

When I call touch some file from docker exec webpack reload all file and it work without restarting container.

有人解决吗?

推荐答案

我找到了两个问题的解决方案:

I found solution for both problems:

1. inotify->只需在"scripts"部分的以下行中编辑package.json:"start": "ng serve --host 0.0.0.0 --poll"，仅Windows主机需要

1. inotify -> just edit package.json in "scripts" section this line: "start": "ng serve --host 0.0.0.0 --poll", required only for Windows host,

热重载->在Dockerfile中添加expose 49153并在docker-compose.yml中添加端口- '49153:49153'，就像提到的@kstromeiraos.

hot reload -> add expose 49153 in Dockerfile and ports - '49153:49153' in docker-compose.yml like @kstromeiraos mentioned.
