Keycloak on GCP Cloud Run

[valsaraj]

We need to deploy Keycloak for an internal application. 

Is Keycloak suitable to run on GCP Cloud Run? Keycloak's database will be in Cloud SQL.

I am concerned regarding this SO link: https://stackoverflow.com/questions/59130538/run-keycloak-with-googlecloud-run

Other cost effective options are to deploy on  Compute Engine or App Engine.

Please let me know your thoughts.

Not being familiar with Keycloak it is hard to answer definitively, but as per the SO link, Cloud Run applications need to be stateless from a container standpoint (of course they can use an external service for state) but it does seem that Keycloak relies on an on-server caching mechanism and clustering for high availability, see: 

https://www.keycloak.org/server/caching

To me this says that Cloud Run might have issues.  Have you considered GKE Autopilot as an alternative?

GKE is costly compared to other options for an internal staging application. I am looking on GAE now. Ref: https://nl.devoteam.com/expert-view/deploying-keycloak-on-google-app-engine/

Did you manage to run keycloak ook GAE Valsaraj? 
Ive tried to do the same for several days, but kept running into 404 errors. Any help would be greatly appreciated!
