PROFILE

Gregory Thiemonge

Worked on the openstack-k8s-operators suite to deliver robust Octavia load balancing and data plane adoption features for distributed cloud environments. Leveraged Kubernetes, OpenStack, and Shell scripting to implement DCN-specific network configurations, automate VLAN and bridge mappings, and integrate Redis-backed jobboard support within the architecture repository. Enhanced the Octavia adoption process by introducing prelaunch validation, automated failover, and streamlined migration steps, reducing risk and downtime. Addressed critical bugs in firewall zone handling and network configuration workflows, improving reliability across multi-AZ deployments. Updated documentation and deployment templates to reflect these changes, ensuring maintainable, production-ready infrastructure as code for cloud-native operations.

Monthly summary for 2025-03: Delivered a targeted bug fix in the data-plane-adoption workflow to harden Octavia adoption against misconfigurations. The core change corrected a faulty grep regex used during Octavia adoption and added an exclusion for DNS-related NNCPs to prevent unintended updates. This work was performed in repository openstack-k8s-operators/data-plane-adoption and tracked under commit d391d6b7140fa12152cc7a67bf9bc86f62647bab. The update improves stability and safety of Octavia network configuration deployments.
