Summary

openCenter is a Kubernetes platform for provisioning and managing clusters with GitOps automation, security controls, observability, backup, and lifecycle management. It runs on OpenStack, VMware vSphere, AWS, bare metal, Kind, and air-gapped environments. Its CLI uses declarative YAML to define infrastructure, Kubernetes, services, and secrets, validating schemas and business rules before generating infrastructure-as-code, Kubespray inventory, and FluxCD manifests with Kustomize overlays. Integrated 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 features include Kyverno policies, Pod Security Admission, NetworkPolicies, and group-based Keycloak access controls. Secrets support SOPS Age encryption in Git and Kubernetes encryption at rest. The free Community plan is self-supported for evaluation and development; paid plans start at $125/mo. Rackspace Technology develops and maintains openCenter.

Who it is for

openCenter is for teams provisioning or operating Kubernetes clusters across supported infrastructure, including air-gapped sites. Its free self-supported plan is positioned for builders and proofs of concept; production users can select paid support tiers.

What is good

Supports air-gapped and bare-metal environments.
CLI generates GitOps manifests from declarative YAML.
Includes monitoring, logging, and tracing components.
Secrets support encryption in Git and at rest.

What to know first

Community support has no guaranteed response time.
The website publishes no specific SOC 2 or ISO 27001 claims.
Paid plans start at $125/mo.

Verdict

openCenter combines cluster lifecycle tooling with security and observability components across several environments. Community use is self-supported, while paid tiers list support response targets for covered issues.
