Static MAC Address for App/Pod

[TempleHasFallen]

It seems for now, every time an app is restarted/started, the interface receives a new MAC address (using external interface).

While this does not present an issue when using a Static IP address, it definitely is an issue if a static MAC is required (ex. trying to assign reserved address via DHCP or firewall functions based on MAC).

Is there any feature which will allow setting a static MAC address for an app? For regular docker containers it is a simple as

Code:

--mac-address=12:34:56:78:89:0A

Any ideas?

Expecting the same feature. My router relies on a static MAC for NAT.

Also interested in this.

Same here, a static MAC Address would be nice.

While I have no experience with Scale, I know a bit about Docker and K8S. So my thoughts may be not applicable here.

In K8S the use of fixed IP addresses does not really work due to the highly dynamic nature of deployments. So instead one needs to properly set up the DNS in K8S and work only with hostnames. I would assume the same applies here. Again, I may be completely wrong here.

+1 from me as well.

Unifi:
Without static MACs, there's no alternative way to assign route rules on endpoints

+1 for me as well, also useful for Vlans, but don't think Kubernetes supports this.

And one of the main reasons I like jails.

Anyone ever figure out how to specify a MAC address for a container using an external interface? Or is this still a feature everyone is waiting for?

Thanks,
Harry

Not on Bluefin at least. Need to use static IP for now.

I wish they'd introduce XLC containers in scale as a substitute for jails in core, then we could have mac addresses per app to allow dns reservation and vlan assignments.
