Cristian Campos-Rivera focused on restoring Tempest privileged mode functionality in the openstack-k8s-operators/test-operator repository. He addressed a core issue where Tempest PodCapabilities were left empty, which prevented privileged network operations from functioning as intended. By adding the NET_ADMIN and NET_RAW Linux capabilities, Cristian ensured Tempest could perform necessary network administration and raw socket tasks, aligning its configuration with other test frameworks such as AnsibleTest and Tobiko. Working primarily with Go and leveraging his DevOps and Kubernetes expertise, he improved the reliability of end-to-end network tests and reduced test flakiness, contributing to more consistent continuous integration workflows.
