In their own words
openCenter
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.
