DNS is broken after node reboot #8144
This is blocking #7580 (test reboot).
I originally ran into this trying to run the guestbook test after the nodes had all rebooted; here is the log for the failed guestbook test.
I added more logging to help understand what is happening. I added the following logging after this line:
Logf("Call to makeRequestToGuestbook(client, cmd='%s', arg='%s', ns='%s') failed.", cmd, arg, ns) Logf("\t response: expected '%s', got: '%s'", expectedResponse, res) Logf("\t error: expected '<nil>', got: '%v'", err)
The first time it's called I get an error that says
Just to make that more readable, the error before the stack trace is:
Any tips or help greatly appreciated. I'm not sure where in the tcp / services / php / redis stack this is going wrong.
This is actually fairly easy to reproduce:
This is done programmatically in #7580 and tests start breaking, including guestbook, DNS, elasticsearch, and influx / heapster. Any help greatly appreciated!
What does reboot have to do with DNS? That's bizarre. Trying to repro

kube2sky is crashlooping with the following error:
Yeah, the crashloop explains why endpoints controller isn't making any endpoints (I am getting nervous because there's been NO BUGS in my rewrite of endpoints controller, so there's probably a really awful one waiting to bite us, but this is not it.). This is clearly #7958. Let's just close this as a dup?
