Bootstrap cluster when DNS entry is empty?

clarkdanielsclarkdaniels EntrantInactive User Role Beginner
Hi, I'm using XtraDB 5.6 with consul for service discovery via DNS and the cluster is failing to bootstrap when there are no nodes yet available.

In my.cnf I have this set up on all nodes, and it works great when the cluster is bootstrapped on one node: wsrep_cluster_address=gcomm://db.service.consul

With the above, I can automatically add any number of new nodes to my cluster without intervention.
But when all three of my nodes are down I get this in my error.log and the cluster fails to bootstrap: "Failed to resolve tcp://db.service.consul:4567" and my cluster won't bootstrap.

I guess this isn't totally unexpected behavior, but if I were to leave my cluster_address as empty gcomm:// my cluster bootstraps as expected, and since DNS is returning 0 node addresses I would think the node would bootstrap itself.

Can anyone think of a workaround for this, or is this a bug?

Thanks for your time and input!
