Stratum v1.0.0-rc.56

Release candidate. You can now choose an endpoint's MAC address instead of taking the one assigned to it.

Added

• Give an endpoint a specific MAC address. Each endpoint is an IP paired with a MAC, and until now the MAC was assigned for you with no way to influence it. That is fine when a workload takes whatever address it is given, but not when it already has one — a virtual machine image with a fixed address, an appliance whose licence is tied to one, or a machine being moved onto Stratum that has to keep its identity.

cenvero-str-ctl network attach <network-id> --ip 10.20.0.50 --mac 52:54:00:ab:01:02
cenvero-str-ctl network set-mac <endpoint-id> 52:54:00:ab:01:02

The same is available over the API: pass mac when attaching, or PUT /api/v1/networks/{id}/endpoints/{eid}/mac. Leaving it out keeps the assigned address, so nothing changes for existing setups.

• Find an endpoint by its MAC. GET /api/v1/networks/{id}/endpoints?mac=… returns just that one, which is the practical way to answer "which endpoint is this workload on" when reconciling against a hypervisor — the full listing of a /24 is 254 entries.

An address already in use by another endpoint is refused and the response names the one holding it. Multicast addresses are refused as well: one can never be a source address, so a workload could not send from it.

Documentation

The CLI Reference and Management API Reference cover both, including when you would want a specific address rather than the assigned one. Already live.
