a question about KubernetesConfigOptions

[Debasish Ghosh <gh...@gmail.com>]

Hello -

In
https://github.com/apache/flink/blob/master/flink-kubernetes/src/main/java/org/apache/flink/kubernetes/configuration/KubernetesConfigOptions.java
the various supported options are declared as constants.

I see that there is no support for options like Volumes and VolumeMounts.
Also I see entries for JOB_MANANGER_CPU and TASK_MANAGER_CPU but not for
JOB_MANAGER_MEMORY and TASK_MANAGER_MEMORY. How do we accommodate these if
we want to pass them as well ? I see that the class is annotated
with @PublicEvolving - just wanted to clarify if these are planned to be
added in future.

regards.

Hi Debasish Ghosh,

Thanks for the attention on native K8s integration of Flink.

1. For volumes and volumes mount, it is not supported now. And we are
trying to get it done via pod template. Refer here[1] for more information.

2. Currently, on different deployments, Flink has different cpu config
options. But for the memory, all the deployments share the same config
options. You could find more information here[2].
* yarn.appmaster.vcores
* yarn.containers.vcores
* kubernetes.jobmanager.cpu
* kubernetes.taskmanager.cpu

3. You are right. This class is PublicEvolving and we may introduce more
config options in the future(e.g. pod template related).
