deployment - Locally deploying a GCloud app with a custom Docker image -

i have been deploying app bash terminal using app.yaml script , command: gcloud app deploy app.yaml

this runs main.app script set environment custom made docker image. how can deploy locally can make small changes , see effects before deploying takes quite while?

if want run app locally, should able outside of docker container. place few restrictions on environment - largely need make sure you're listening on port 8080.

however if want test locally docker - can...

# generate dockerfile applications gcloud beta app gen-config --custom  # build docker container docker build -t myapp .  # run container docker run -it -p 8080:8080 myapp 

from there, should able hit http://localhost:8080 , see app running.

hope helps!
