Troubleshooting Pub/Sub Message Delivery and VPC Network Peering for Cloud Run and Cloud SQL

[yuki-hara]

The Pub/Sub messages used for starting Cloud Run for Anthos are no longer being received. Consequently, while reviewing the configurations of the managed GKE and VPC, it was discovered that the status of VPC Network Peering to cloudsql-postgres had become inactive.

Although it is unclear whether this directly relates to the initial issue of Pub/Sub messages not being delivered, please provide guidance on how to rectify the VPC Network Peering configuration for Cloud SQL. Additionally, if you have any insights into the situation where Pub/Sub messages are not being received, kindly share them. Currently, when sending a POST request to the domain mapped to Cloud Run for Anthos using the curl command, a proper response is received, indicating that there may not be an issue on the Cloud Run for Anthos side.

Hi @yuki-hara, 

Since you’ve mentioned that the VPC Peering for the cloudsql-postgres had become inactive, kindly delete the peering and re-create it using the steps indicated on this link.
