Re: healthcheck task?
I found javadocs for package "Protos.HealthCheck": http://mesos.apache.org/api/latest/java/org/apache/mesos/Protos.HealthCheck.html but not a single example of how to use it On Wed, Dec 7, 2016 at 11:22 AM, Alex Rukletsov <a...@mesosphere.com> wrote: > What exactly do you mean under "health check task"? > > On Wed, Dec 7, 2016 at 5:09 PM, Victor L <vlyamt...@gmail.com> wrote: > >> Can someone recommend simple example of how to add healthcheck task to >> java framework? >> Thanks, >> >> >
Re: healthcheck task?
My app is supposed to accept tcp connections on the port 3309 after successful deployment. The mesos task to periodically check for that i am referring as "healthcheck task". My understanding is that you can do the same in Marathon app deployments with json code like: "portIndex": $PORT1, "protocol": "TCP", "gracePeriodSeconds": 300, "intervalSeconds": 60, "timeoutSeconds": 20, On Wed, Dec 7, 2016 at 11:22 AM, Alex Rukletsov <a...@mesosphere.com> wrote: > What exactly do you mean under "health check task"? > > On Wed, Dec 7, 2016 at 5:09 PM, Victor L <vlyamt...@gmail.com> wrote: > >> Can someone recommend simple example of how to add healthcheck task to >> java framework? >> Thanks, >> >> >
healthcheck task?
Can someone recommend simple example of how to add healthcheck task to java framework? Thanks,
Re: forcing framework to re-schedule?
How can i explicitly kill the task from my class?

Re: forcing framework to re-schedule?
It checks if process is functional. I don't think standard healthchecks wouldn't be sufficient for my purpose and my question still stands: how to use result...

forcing framework to re-schedule?
Hello, I am writing "healthcheck agent" for mesos deployment framework as independent thread periodically checking if main process ( started by framework) is running... What would be the mechanism to "communicate" failure to the framework to cause specific outcome? For example: how can i use failure to cause framework to reschedule deployment on different node? Thanks,
mesos and coreos?
I am confused: what's the value of mesos on the top of coreos cluster? Mesos provides distributed resource management, fault tolerance, etc., but doesn't coreos provides the same things already? Thanks
