Tried two two tutorials on my personal GCP.
cloud storage (upload a file, then return a public url for download; another download link)
I may delete those bucket and files later on, as hosting costs money (app engine, cloud storage). Update: I disabled the app (here is one article talking about disable / delete app engine app). In simple term: I go to project, app engine, go to settings, click disable. Btw, I noticed all 73 cents charges for about 20 hours is from app engine.
From GCP Console Dashboard, I saw Resource
App Engine
2 versions
Storage
4 buckets
GCP Service Broker
For PCF, the approach above did not work (got an error on line 61 on the example above). I followed the steps for GCP service broker and pushed it to our pcf.
Virus Scan
Automating malware scanning for documents uploaded to Cloud Storage
PCF Sample App
It looks like with the VMWare Pivotal acquisition / integration, their hello world sample app website also moved. Here is the new link.
