My Google Cloud Container Builder steps are touching information that should not leave the European Union. Is it possible to restrict the region for a build so that it won't be executed in us-central1 for example?
I know I can define the region, where the resulting images are stored, but that does not mean the processing happens within the EU, or am I wrong?
You are correct that you cannot at this time define the region where the processing happens. However, since all processing of your build is ephemeral, data lives in the arbitrarily-selected processing region only for the brief lifetime of your build.
If you believe you need more control over regionality than this ephemeral lifespan offers, please make this a formal feature request by sending details regarding your use case to gcr-contact@google.com.
