PROFILE

Raúl Hernández

Worked on automation and CI/CD infrastructure across repositories such as openshift-kni/cnf-features-deploy, openshift/release, and konflux-ci/build-definitions, focusing on reproducible builds, workflow optimization, and deployment reliability. Delivered hermetic build systems using Tekton pipelines and lockfile management, enabling deterministic outputs and improved security. Enhanced CI efficiency by introducing conditional job execution and integrating Konflux trust, reducing unnecessary runs and feedback latency. Implemented image tag to SHA256 digest conversion for OLM catalogs, improving artifact traceability. Leveraged YAML, Bash, and Dockerfile to manage configuration, containerization, and deployment logic, with a strong emphasis on maintainability, compliance, and scalable DevOps practices.

Dec 1, 2025

December 2025 monthly summary for konflux-ci/build-definitions: Delivered an image tag to SHA256 digest conversion feature in the OLM catalog with configurable enablement. The feature processes only images without existing digests, adds parameters and logic to control the conversion, and integrates the change into the deployment workflow. Commit 5ccb1868b6f7a6682b28286d78dd3a954ba16f24 accompanies the changes.

Month: 2025-11 | OpenShift KNI: cluster-group-upgrades-operator. Key feature delivered: Hermetic catalog rendering in the FBC pipeline, enabling reproducible builds and safer upgrade catalogs. Implemented a new run-opm-command integration and added catalog-format management to support hermetic builds. This work reduces drift between source catalogs and deployed configurations and improves upgrade reliability for cluster environments. References: commit 7c4ffca6938cb17608f808b74c96e0bd34641d65, CNF-20549.

August 2025: Delivered targeted CI workflow optimization for the openshift/release repository to reduce unnecessary CI runs and accelerate feedback. Implemented conditional ci-job execution by configuring always_run to false and adding skip_if_only_changed to both main and presubmits, ensuring CI validates only changes that impact the release process. This reduces CI load, shortens queue times, and improves developer productivity. The change is backed by commit 351f352896e3034cb36aba8487b371c07603b625 ("make oran ci-job conditionally required (#67754)").

July 2025 highlights for openshift/release: Delivered Konflux CI integration by configuring the oran-o2ims CI to trust the Konflux app and skip Prow checks for Konflux-related changes. This aligns CI policies with Konflux integration, reduces unnecessary CI runs, and speeds up feedback for Konflux-related changes.
