Oracle Cloud Infra Admin-Devops with Redhat Openshift-Senior

OpenShift Cluster Deployment & Operations

• Install and operate OpenShift 4.x on-prem and in the cloud (UPI/IPI), including control plane and worker setup.
• Perform cluster upgrades, certificate management, and etcd backup/restore with DR readiness.
• Monitor and troubleshoot using Prometheus/Grafana and maintain runbooks for common incidents.

OpenShift Virtualization (KubeVirt)

• Manage OpenShift Virtualization (KubeVirt) to run and live-migrate VMs alongside containers.
• Configure VM networking (Multus/SR-IOV) and storage integration (ODF/Ceph, NFS, Fibre Channel).
• Enable VM image import and backup/restore using CDI and OADP/Velero.

CI/CD Pipelines & DevSecOps

• Build and support CI/CD pipelines on OpenShift using Jenkins.
• Manage artifact and image repositories (Nexus) and support disconnected setups.
• Implement DevSecOps controls: SonarQube quality gates, image scanning (ACS/Trivy) and GitOps delivery (Argo CD).

Networking, Storage & Platform Integration

• Configure networking: VLANs, OVN-Kubernetes policies, egress and load balancing (HAProxy/MetalLB).
• Integrate identity and security basics: LDAP/AD, RBAC, wildcard DNS and TLS certificates.
• Provision storage classes and set resource controls (quotas and LimitRanges) for namespaces.

Automation, IaC & Air-Gapped Environments

• Automate provisioning and day-2 tasks using Ansible, Helm and Kustomize.
• Support air-gapped installs by mirroring OpenShift releases/operators/images and managing ICSP/IDMS.
• Use Terraform for supporting services (DNS, load balancer, IPAM) and maintain drift control via GitOps.

Security, Compliance & Reliability

• Apply platform security: SCCs, Pod Security standards and NetworkPolicy; align with CIS hardening.
• Integrate secrets and audit controls (Vault, SIEM) and support reliability through tuning and RCA.
• Create clear diagrams/runbooks/SOPs and support on-call and knowledge transfer for L1/L2 teams.
