Running
|
|
|
|
|
-------
|
|
|
|
|
|
|
|
|
|
Since this app makes use of Compose's experimental networking support, it must be started with:
|
|
|
|
|
|
|
|
|
|
$ cd vote-apps/
|
|
|
|
|
$ docker-compose --x-networking up -d
|
|
|
|
|
|
|
|
|
|
The app will be running on port 5000 on your Docker host, and the results will be on port 5001.
