Aya Hosni contributed to the argoproj/argo-cd repository by addressing Kubernetes image registry compatibility during a one-month period. She migrated image references in Kubernetes install manifests from k8s.gcr.io to registry.k8s.io, ensuring continued reliability as upstream registries evolved. This update, implemented using YAML and leveraging her skills in CI/CD and DevOps, reduced the risk of image pull failures across diverse cluster environments. Aya documented the migration process to support future registry transitions, enabling smoother upgrades. While the work focused on a single bug fix rather than new features, it demonstrated careful attention to infrastructure reliability and cross-environment consistency.
