Ian Horne migrated production Azure Container Registry references across the hmcts/civil-sdt and hmcts/civil-sdt-commissioning repositories, ensuring deployments consistently pulled correct images and dependencies. He updated Chart.yaml, Dockerfile, and values.yaml files, aligning CI/CD pipelines and deployment configurations to reduce environment drift and improve release safety. When a misconfiguration was detected, Ian executed a rollback to restore secure registry settings, demonstrating careful change management. His work leveraged skills in Kubernetes, containerization, and YAML, delivering clearer environment parity and traceability. Over the month, Ian delivered one feature and resolved two bugs, focusing on deployment reliability and security across production environments.
