Sep 1, 2025September 2025: Focused on stabilizing the CHPay payment integration within WISVCH/gke-cluster. Delivered activation of CHPay in deployment, corrected Mollie payment and webhook endpoints, and standardized CHPay-related environment variable names to ensure reliable payments and webhook handling. Introduced a rollback path by enabling CHPay deactivation in release configurations. These efforts improved payment reliability, reduced configuration drift, and strengthened release governance, supporting faster recovery in case of issues.

Nov 1, 2024November 2024 monthly summary for WISVCH/gke-cluster focusing on Dienst2 release configuration changes related to allowed hosts. Implemented a two-step workflow: enabling localhost for local development/testing during early stages and subsequently tightening access by removing localhost to enforce access via designated domain and internal cluster network addresses. This delivers both rapid local iteration capability and improved security for production deployment.
