Michal Kralik

Michal Kralik developed and enhanced features for the percona/everest and percona/everest-operator repositories, focusing on secure, reliable, and flexible database lifecycle management in Kubernetes environments. He implemented environment-aware installation for OpenShift, robust error handling, and role-based access control for backup and restore operations, using Go and YAML to ensure maintainable, cloud-native solutions. His work included CRD affinity support for granular scheduling, improved logging, and dependency management, addressing both operational efficiency and compliance. By integrating API development, CLI tooling, and RBAC, Michal delivered well-architected solutions that reduced deployment risk and improved usability for complex, multi-cluster database workflows.

December 2024 monthly summary focusing on security, reliability, and deployment flexibility across Everest and Everest-Operator. Key features delivered include Role-Based Access Control (RBAC) for database backups and restores, restricting actions by user permissions tied to database clusters and filtering restore listings accordingly. Introduced Kubernetes CRD Affinity support for database cluster components through Everest-Operator, enabling per-component scheduling preferences via new Affinity fields and updated deepcopy logic. Major bug fix improved validation messaging for duplicate backup storage configurations, ensuring the error clearly states when URL, bucket, and region collide, and included dependency version updates in percona-helm-charts. These changes together reduce risk, improve usability, and enable more precise resource governance.

October 2024: Implemented OpenShift Everest support with environment-aware installation and management. The feature detects whether the runtime is OpenShift and adjusts OLM/catalog deployment steps during install, uninstall, and upgrade, with new flags for manual control over environment detection and OLM operations. This work lays the foundation for safer, more predictable Everest lifecycle in OpenShift clusters and aligns with customer demand for streamlined OpenShift deployments.
