Cleaning up old failed tasks?

[naemono]

This is more of a question than an issue.

i was wondering why I was getting duplicative service ids for the same service, even though it was an old deployment of the service.

from here:

https://github.com/CiscoCloud/mesos-consul/blob/master/mesos/mesos.go#L150-L158

It appears that only running tasks are investigated.

I'm seeing this in my setup:

http://myhost:8500/v1/catalog/service/nginx-test

[

]

Only one of these tasks is actually active.

Does de-registration not remove these?

Thanks for any further insight you can give.

Ok, digging through the code this morning, I think I've found the issue.

Here:

https://github.com/CiscoCloud/mesos-consul/blob/master/mesos/mesos.go#L161

You're not checking if an error was returned from m.Registry.Deregister()

This seems more appropriate:

    // Remove completed tasks
    err := m.Registry.Deregister()
    if err != nil {
        log.Error(err)
    }

I'll get a PR for this shortly.

@naemono any chance for the PR ? 🎄
