PROFILE
Florian Streibelt
Worked extensively on the sapcc/helm-charts repository, delivering features and fixes that enhanced security, reliability, and operational flexibility for OpenStack and Kubernetes deployments. Focused on Helm chart development, the work included implementing secure credential handling, dynamic multi-region service deployment, and automated DNS backup workflows. Leveraged Go, YAML, and Shell scripting to streamline configuration management and CI/CD processes, while introducing policy updates and dependency management improvements. Addressed deployment stability by refining liveness probes and simplifying seeder configurations, reducing operational risk and maintenance overhead. The approach emphasized automation, maintainability, and adherence to best practices in cloud infrastructure and DevOps environments.

Mar 1, 2026March 2026 delivered scalable, region-aware nanny deployment and tightened seed isolation in OpenStack integration, driving reliability and business scalability. Key features include dynamic multi-region nanny deployment with Helm chart iteration over an arbitrary number of nannies and improved default configuration for designate-nanny (autorun, log levels) and seed config for the global nanny. A critical bug fix isolated seeder behavior by ignoring the 'dnsglobal' namespace, ensuring only the global seeder handles seeds. These changes reduce operational toil, lower risk during regional expansion, and improve observability through standardized defaults. Technologies demonstrated include Helm templating, Kubernetes/YAML configuration, OpenStack seeder logic, and multi-region deployment patterns.

Dec 1, 2025December 2025 performance snapshot for sapcc/helm-charts focused on enhancing backup flexibility and reliability in the designate-nanny integration within a multi-region OpenStack environment. Key accomplishments include enabling an out-of-region backup user with restricted API access and moving the nanny-user seed into the nanny Helm charts to support additional user provisioning via secrets. In parallel, deployment stability was significantly improved through a series of fixes across seeds, credentials, and region handling, restoring reliable deployment and operation.

Aug 1, 2025Month: 2025-08 overview focusing on security hardening and operational reliability for DNS backup and logging services in sapcc/helm-charts. Key features delivered include enabling DNS backup capabilities via a new cloud_dns_backup role with Designate/Keystone policy updates, and introducing explicit database credentials for the nsxv3 logstash service in the Neutron Helm chart. These changes enable automated backup workflows, improve credential security, and strengthen governance across DNS and logging components.
