OpenStack Ironic
What OpenStack Ironic is
OpenStack Ironic manages physical machines through discovery, cataloging, enrollment, provisioning, maintenance and decommissioning. Its REST API gives operators a vendor-agnostic interface for managing machines across those stages. Hardware support includes generic Redfish and IPMI types, as well as vendor-specific types. Operators can inspect hardware and run extensible preparation actions before workloads are assigned.
Ironic supports hardware ownership and leasing across separate pools. It can also integrate with OpenStack Networking to isolate workload networks. Its modular design is described for environments with tens, hundreds or thousands of machines. Bifrost, Metal3 and OpenStack Compute are deployment options or related projects. Ironic is free, open source under the Apache 2 license, and offers API access. It runs on Linux and in self-hosted deployments. Operators can configure TLS for outbound image downloads and Redfish BMC connections. The security guide recommends disabling IPMI when modern out-of-band management is available. Bifrost setup requires knowing the bare-metal network interface and having hardware controller credentials.
Who it suits
Ironic suits operators managing fleets of physical machines who need lifecycle controls through an API, hardware ownership and leasing, or image-based provisioning. It is also relevant to teams deploying with Bifrost, Metal3 or OpenStack Compute and able to configure bare-metal networking and hardware controller access.
