How to View Files in a Google App Engine Docker Container

This post has been adapted (abridged) from the Google Cloud Platform (GCP) Debugging an Instance documentation. I wanted to see the file structure that was being deployed to my Angular 5 application for my YouTube video highlight web app (Tunnel Video). These are the steps required.

1. Go to your App Engine instances in the GCP console

https://console.cloud.google.com/appengine/instances

2. Find the instance and choose the SSH option to open a terminal in a browser window

3. Once the terminal window for the instance opens, list the docker containers: $ sudo docker ps

4. Find the docker container in the list with your project name in it and then run: $ container_exec containerId /bin/bash

5. This will open a shell in your container. From there, just list your files as usual: ls app
