Wendel Castro enhanced the viasoftkorp/KorpSetupLinux repository by focusing on infrastructure reliability and risk reduction over a two-month period. He implemented a reverse proxy configuration validation to ensure external access settings aligned with certificate requirements, using Ansible and YAML to enforce early error detection and prevent deployment outages. Wendel also removed the on-premise HybridProxy service, updated Docker Compose definitions, and introduced a new API route in the Fabio proxy configuration. Additionally, he improved system administration reliability by adding a retry mechanism for salt-minion connection tests, reducing downtime and streamlining on-premise infrastructure management through Infrastructure as Code practices.
