The 12 factor manifest tells us in point III that apps should retrieve their config from environment variables to strictly separate config from code. “Config” meaning everything that is likely to vary between deployments (staging, production, developer environments, etc). Cloud Foundry allows us to do that very easily using either the manifest.yml file or the cf set-env command. However, this only works for apps which have a dynamic back end. What if we want to configure a front end app that we have pushed to Cloud Foundry using the staticfile buildpack? These apps are, by definition, static so they cannot read out any environment variables. Therefore, if we use this buildpack to deploy an Angular or React app, we cannot use these variables.
