apparently it get caught here:
// Regular expression to extract runSpecId from instanceId // See: https://github.com/mesosphere/marathon/blob/v1.4.0-RC4/src/main/scala/mesosphere/marathon/core/instance/Instance.scala#L244 var instanceIDRegex = regexp.MustCompile(
^(.+).(instance-|marathon-)([^.]+)$`)
func (t TaskHealthChange) TaskID() apps.TaskID { if t.ID != "" { return t.ID } return apps.TaskID(instanceIDRegex.ReplaceAllString(t.InstanceID, "$1.$3")) }`
If I read that correct, it seems that that the ID is empty and therefor uses the regex replacement
I would like to add to this bug, as we are hitting the same thing.
though I would add some extra information.

This is the curated logs during a normal marathon deploy. the task is correctly de-registered, but it cannot re-register, though this only occurs from the register task. After some minutes, when the sync all task is called, the registration of the service works.
msg=Registering Address=10.xx.xx.52 EnableTagOverride=false Id=pyt_my-service-svc.instance-5373f6f3-f523-11e9-9b69-02429c8e109f._app.1_my-service-svc_31586
Unfortunately, the sync is quite infrequent, and this causes downtime for us. We will no doubt increase the frequency of the sync until this issue can be resolved, but this is not ideal. (In this example, we are talking about 3.5 minutes before the service gets registered back in consul)
now testing with 1.5.1 (marathon 1.9.100 from yum repo http://repos.mesosphere.com/el/7/$basearch/) and we see the same
Just to debug some code changes which make it work (but are no real fix in any sense of that combination of words ;)
diff marathon-consul-master/events/task_health_change.go go/src/github.com/allegro/marathon-consul/events/task_health_change.go 24c24 var instanceIDRegex = regexp.MustCompile(
^(.+)\.(instance-|marathon-)([^\.]+)$
)var instanceIDRegex = regexp.MustCompile(
^(.+)$
)30c30 return apps.TaskID(instanceIDRegex.ReplaceAllString(t.InstanceID, "$1.$3"))
return apps.TaskID(instanceIDRegex.ReplaceAllString(t.InstanceID, "$1._app.1"))
So essentially I just take the complete instanceID and put ._app.1 after that, which causes the task to be found. However if the task has more than 1 instance it will fail, also the regex change is just giving back the input, which should be done in a correct way (but hey, I'm an operator, not a programmer).
The data given by the health status change event seems to be
data: {"appId":"/demo/hello-world","instanceId":"demo_hello-world.instance-b98f6bf3- eb61-11e9-af4c-02423f927891","version":"2019-10-10T13:27:36.878Z","alive":true,"eventType":"health_status_changed_event","timestamp":"2019-10-10T13:27:41.929Z"}
So if we can match that instanceId to a field in the task list instead of the id field which does include the ._app.# we should be baconbuyer.
we are working on a fix and hopefully will submit a merge request semi-soon
Is there any update on this topic?
There is a PR but there is a build fail, which JurrianFahner can't reproduce. Not sure what's the hold-up on the reply to his question.
The thing is we stopped developing this project. We still use it in production, but it runs on an older version of Marathon and we only use a subset of features. We don't plan to keep it up to date with Marathon releases.
That being said, we'd be happy to accept PRs and release them for you. We don't want to invest time in debugging the travis build though.
Even better, you could fork this project and continue its development. If you decide so, we can make it official and provide a link in our README.
ok thanks for the update. We'll consider our options at this point.
Hi,
we are looking to upgrade marathon, and also marathon consul. We are testing with Version: 1.4.2 (from apt) and marathon 1.9.
We see that when an application is stopped (by scaling to 0 instances) and then starting by setting 1 instance, the application is not registered in consul (the unregister works fine though). We see the following in the marathon-consul log where I grep the instance UUID:
`grep b98f6bf3-eb61-11e9-af4c-02423f927891 /var/log/marathon-consul.log

So the "Got HealthStatusEvent" registers the following instanceID: demo_hello-world.b98f6bf3-eb61-11e9-af4c-02423f927891 where we see that the instance ID is demo_hello-world.instance-b98f6bf3-eb61-11e9-af4c-02423f927891
So I thought that the marathon event endpoint returns an incorrect instanceid and went on to capture the traffic with tcpflow (tcpflow -i eth1 -c port 8080 >> ~/tcpdump2) that goes through the events endpoint:

And I see no instanceID that lacks the "instance-" prefix. I haven't found anything that resembles this problem and am not sure whether this is a marathon or a marathon-consul problem.
The error is thrown by events/event_handler.go (line 142)
