Hi Mesos community!
We’re in the process of designing a Mesos framework to launch multiple
containers together on the same host and are considering a couple of
approaches. The first is to use pods (with the TASK_GROUP primitive), and
the second is write a custom executor that launches nested containers and
use CNI to handle networking.
With that in mind, we had the following questions:
Questions about pods/task_groups:
-
Is it possible to do healthchecks per task in a pod?
-
Is it possible to allocate a separate IP address per container in a pod?
-
Is there any plan to support the Docker containeriser with pods?
Questions about UCR/Mesos containerizer:
-
Timeframe for debugging tools (equivalent of docker exec, etc)?
-
Is there any performance data about using the Mesos containeriser with
container images versus using the Docker containeriser?
-
how does the Mesos containerizer handle extremely large images?
-
how does the Mesos containerizer handle dozens/hundreds of concurrent
pulls?
If anyone has had any experience using the UCR and/or pods with the sort of
workflow we’re considering, your input would be highly useful!
