Repro steps.

Run up a new docker container with a mounted drive from PowerShell
Install @angular/cli
create a new app
serve the app
make changes from a text editor in the host machine and save
the app does not re-transpile

Commands run are listed below (output removed for brevity)

> docker run -it -p 4200:4200 -p 49153:49153 -v ${pwd}:/app -w /app node /bin/bash
root@3c96e8d8df57:/app# npm i -g @angular/cli
root@3c96e8d8df57:/app# ng new test-app --skip-npm
root@3c96e8d8df57:/app# cd test-app
root@3c96e8d8df57:/app/test-app# npm i 
root@3c96e8d8df57:/app/test-app# ng serve --host 0.0.0.0

Once the app is up and running I open the app folder with VSCode on my host machine and edit a file, for example removing the production mode check in main.ts and save the changes.
I would expect that this action triggers a rebuild of the app as happens when I do this right on the windows host machine

The log given by the failure.

Mention any other details that might be useful.

Following all of the steps performed inside the container on the host machine results in the expected behavior

With your setup you may need to use the '--poll' option with a reasonable value based on your needs (value is in milliseconds).

Closing as working as intended.

[gavinbarron]

Thank you!!! that has solved the problem Legends :)

[Corsseir]

'--poll' flag consumes a lot of cpu so this is not a solution.

[smoke]

@Corsseir my 2 cents - this is OS specific and currently I don't believe there is a better way in this combination - docker + Windows

[Corsseir]

Hm, ok. I though that Windows would be ok for web development since vagrant and docker but I was wrong. Its time to migrate to Linux I guess.

[holms]

--poll flag doesn't give any results at all, all ports opened, by changing template no webpack rebuild happens

[erensogut543]

@Corsseir as he said , after '--poll' my pc consume lots of cpu. Are there any way to ho reloding an angular app with docker ?
