visualize-reservations

Overview ¶

Tool to visualize failover reservations and their VM connections

Usage:

go run tools/visualize-reservations/main.go [flags]

Flags:

--config=path              Path to JSON config file (CLI flags override config values)
--sort=vm|vm-host|res-host  Sort VMs by UUID, VM host, or reservation host
--postgres-secret=name      Name of the kubernetes secret containing postgres credentials (default: cortex-nova-postgres)
--namespace=ns              Namespace of the postgres secret (default: default)
--postgres-host=host        Override postgres host (useful with port-forward, e.g., localhost)
--postgres-port=port        Override postgres port (useful with port-forward, e.g., 5432)
--postgres-port-forward      Automatically run kubectl port-forward for postgres
--postgres-port-forward-service=name       Service name for port-forward (defaults to secret host)
--postgres-port-forward-local-port=port    Local port for port-forward (defaults to postgres port)
--postgres-port-forward-remote-port=port   Remote port for port-forward (defaults to postgres port)
--views=view1,view2,...     Comma-separated list of views to show (default: all)
                            Available views: hypervisors, vms, reservations, summary,
                            hypervisor-summary, validation, stale, without-res, not-in-db, by-host
--hide=view1,view2,...      Comma-separated list of views to hide (applied after --views)
--filter-name=pattern       Filter hypervisors by name (substring match)
--filter-trait=trait        Filter hypervisors by trait (e.g., CUSTOM_HANA_EXCLUSIVE_HOST)
--hypervisor-context=name   Kubernetes context for reading Hypervisors (default: current context, backward compatible)
--hypervisor-contexts=ctx1,ctx2,...        Kubernetes contexts for reading Hypervisors
--reservation-context=name  Kubernetes context for reading Reservations (default: current context, backward compatible)
--reservation-contexts=ctx1,ctx2,...       Kubernetes contexts for reading Reservations
--postgres-context=name     Kubernetes context for reading postgres secret (default: current context)

To connect to postgres when running locally, use kubectl port-forward:

kubectl port-forward svc/cortex-nova-postgresql 5432:5432 -n <namespace>
go run tools/visualize-reservations/main.go --postgres-host=localhost --postgres-port=5432
