Spec score 7.2 #21 of 29 in Kubernetes Management Platforms

What it is

openCenter provides upstream Kubernetes with GitOps automation, security hardening, observability, backup and lifecycle management. It runs on OpenStack, VMware vSphere, AWS, bare metal and air-gapped sites. Its CLI uses declarative YAML to define infrastructure, Kubernetes, services and secrets, applying schema validation and business-rule checks before generating infrastructure-as-code, Kubespray inventory and FluxCD manifests with Kustomize overlays. Listed pre-hardened services include cert-manager, Kyverno, Keycloak, Harbor, Velero, MetalLB, Longhorn, Calico, PostgreSQL Operator and OpenStack CSI. Observability components include Prometheus, Grafana, Alertmanager, Loki, Tempo and OpenTelemetry. Security controls include Kyverno ClusterPolicies, Pod Security Admission, NetworkPolicies and group-based Keycloak OIDC access controls. Secrets can use SOPS Age encryption in Git, Kubernetes encryption at rest and key rotation. Air-gap packaging uses a Zarf artifact for images, charts and binaries, with signing and SBOM generation. Community is free; paid plans start at $125/mo. Rackspace Technology develops and maintains openCenter.
