Telco Blueprint

Purpose: For platform engineers and operators in telecommunications, describes how the Telco blueprint extends the openCenter platform foundation for edge-to-core deployments at scale.

Overview​

Telco infrastructure does not get the luxury of "we will fix it in the next sprint." The Telco blueprint gives network and platform teams the operational controls to run Kubernetes at scale without the 3am surprises.

What You Get​

  • Standardized cluster operations from edge sites to core data centers. No snowflakes.
  • Policy-driven delivery for high-change, high-availability workloads that cannot afford rollback failures.
  • Operational tooling that helps teams recover in minutes, not hours.

Capabilities​

Edge-to-Core Deployment Model​

One deployment model, one ops workflow, whether it is running in a central DC or a cell tower cabinet:

  • The same openCenter CLI config structure works for core data center clusters and edge site clusters. Differences are captured in Kustomize overlays (node counts, resource limits, storage backends), not in separate toolchains.
  • Edge clusters can run with reduced control plane sizes (single-node or three-node) while maintaining the same security and observability stack.
  • Centralized observability aggregates metrics and logs from all clusters into a core Prometheus/Loki/Grafana instance.

See Reference Topologies for edge-core topology patterns.

Multi-Cluster Fleet Management​

  • Fleet-wide configuration changes propagate through Git. Update the gitops-base tag in one PR, roll out to all clusters through FluxCD reconciliation.
  • Consistent security policies across the fleet — the same Kyverno ClusterPolicies and PSA configuration apply to every cluster regardless of location.
  • Centralized RBAC via Keycloak — operators authenticate once and access any cluster in the fleet based on group membership.

Policy-Driven Delivery​

  • Versioned blueprints and GitOps workflows so you can push changes to critical services without holding your breath.
  • Kyverno policies validate every resource before admission. Non-compliant changes are blocked at the API server, not discovered in production.
  • FluxCD drift detection ensures clusters stay in sync with the declared state. Unauthorized manual changes are automatically reverted.

See Drift Detection for reconciliation strategies.

Operational Recovery​

  • Standardized runbooks for common failure scenarios (node failure, service crash, network partition).
  • Automated remediation through FluxCD — if a service is deleted or modified, FluxCD restores it from Git within the reconciliation interval.
  • Velero backup schedules configured per cluster tier (core clusters: frequent snapshots; edge clusters: daily snapshots with longer retention).

See Backup & Restore for configuration details.

Air-Gap Considerations​

Many telco edge sites have limited or no internet connectivity. The Telco blueprint is fully compatible with Air-Gap Deployments:

  • All container images, Helm charts, and OS packages are packaged into signed Zarf artifacts.
  • Edge bastion hosts serve as local registries and package repositories.
  • Updates are delivered via physical media transfer or secure file transfer to the bastion.

Relationship to the Platform Foundation​

The Telco blueprint layers on top of the openCenter platform foundation. It adds edge deployment patterns, multi-cluster fleet management configuration, and telco-specific operational constraints (tighter SLAs, faster recovery targets, air-gap readiness for edge sites).
