What openCenter is
openCenter is a Kubernetes platform for provisioning and managing clusters with GitOps, security controls, observability, backup, and lifecycle management. It supports OpenStack, VMware, AWS, bare metal, Kind, and air-gapped environments, with customer-managed control planes and multi-cluster management. Its CLI uses declarative YAML to configure infrastructure, Kubernetes, services, and secrets, then generates infrastructure-as-code, Kubespray inventory, and FluxCD manifests with Kustomize overlays. The listed services include cert-manager, Kyverno, Keycloak, Harbor, Velero, MetalLB, Longhorn, Calico, PostgreSQL Operator, and OpenStack CSI. Monitoring options include Prometheus, Grafana, Alertmanager, Loki, Tempo, and OpenTelemetry. Security features include policy enforcement, Pod Security Admission, NetworkPolicies, and Keycloak group-based access. Community is free and self-supported; paid plans start at $125/mo, with Essentials priced on request. The maker does not publish specific certification claims such as SOC 2 or ISO 27001.
