After sorting out the mess on my cluster as exposed on my previous post, I started migrating the consul servers to the latest, 1.11.2, while most of the clients in 0.8.5 and I am facing a really weird scenario: Tags are literally flapping in the new servers.
Flapping meaning they disappear and reappear completely, from all the 5 servers. They start in synchrony, and then one disappears, then another, then all, the all back… I couldn’t find a pattern, although when tags are back they don’t last more than 20-30 secs and off again for 1-2 minutes.
Ok… Am I right to assume that consul servers belong implicitly to the service “consul”? If I remove that definition, they boot up and work in the same fashion, and, in fact, if I change the service id/name to something different i.e.: konsul, there are two services per node (as in multiple service definitions), and, in those secondary ones, tags work as expected.
I assume this is by design, right?
If so, I have found my workaround already, by creating that secondary service with the tags I need.
