Upbound Hub · upbound bundle Query and mutate Upbound Hub, the central API for an Upbound Platform deployment, which gives one cross-fleet view of control planes, spaces, realms, types, packages, resources, identity providers, and the image catalog. Use when asked about fleet-wide state ("how many resources are unhealthy", "list control planes", "what types are deployed across the fleet", "show resources in <control plane>"), or to create, update, or delete Hub objects. Not for a single control plane's own API server, and not for Crossplane resources managed inside one.
