PROFILE
Justin Riley
Justin Riley engineered and maintained the OCP-on-NERC/nerc-ocp-config repository, delivering robust cloud infrastructure and Kubernetes-based solutions over a nine-month period. He implemented features such as GPU workload enablement, secure secret management with Vault, and multi-cluster OpenShift upgrades, focusing on production stability and upgrade readiness. Using YAML, bash, and Kustomize, Justin standardized network configurations, automated SSH key rotation, and integrated monitoring with Nagios. His work addressed both feature delivery and critical bug fixes, demonstrating depth in DevOps, infrastructure as code, and operator lifecycle management. The resulting platform improved reliability, security, and scalability for complex, multi-environment OpenShift deployments.

Jun 1, 2025June 2025 monthly highlights for OCP-on-NERC/nerc-ocp-config: Key features delivered: - SSH keys rotation and admin access hardening: updated SSH authorized_keys on master and worker nodes; replaced the old admin key with a new one and added a debugging key for secure/debug access. - Node Feature Discovery upgrade to OpenShift 4.17: upgraded NFD image to v4.17 to align with OpenShift 4.17 upgrade path. - OpenShift cluster upgrade cycle: executed a multi-step upgrade path from 4.15.51 → 4.16.41 → 4.17.31, addressing API removals compatibility across the prod environment. - OpenShift operators and components upgrades: updated core operators and components (ODF, logging, RHOAI, knative-serving, GPU operator) to the latest stable versions. - ArgoCD monitoring enhancements: enabled Nagios monitoring of ArgoCD resources by granting access to the ArgoCD API group and related health checks. Major bugs fixed: - Reverted htpasswd authentication in production and removed htpasswd from kustomization.yaml to restore a secure baseline. Overall impact and accomplishments: - Improved security posture through htpasswd removal and SSH key hardening; enhanced upgrade readiness and API compatibility with OpenShift 4.17; boosted observability with ArgoCD Nagios monitoring; and streamlined network configuration management via centralized IP forwarding practices. Technologies/skills demonstrated: - OpenShift 4.17 upgrade path, Node Feature Discovery, multi-step cluster upgrades, operator/component upgrades, ArgoCD RBAC monitoring, SSH key management, and centralized network configuration." ,
