Yang Wang commented on FLINK-20324:
-----------------------------------
[~lublinsky] Thanks for your efforts on the native K8s integration.
# You could find the environment setting in {{InitJobManagerDecorator}} and
{{InitTaskManagerDecorator}}.
# For the secret config options, it makes sense to distinguish them for
JobManager and TaskManager. But I am sure whether it is really necessary. Feel
free to create a new ticket if you come across this problem in you production
environment. And we could make the current config option as default if
specific(jobmanager/taskmanager) config option is not set.
# I am afraid we do not have much progress on the pod template. So I agree
with you that we could have the volume mounting separately. It is a more common
feature that we need when using native K8s integration in production. Let's
keep the volume mounting discussion under FLINK-15649. If we reach an
agreement, I think you could take over that ticket and start the PR working.

> Key: FLINK-20324
> URL: https://issues.apache.org/jira/browse/FLINK-20324
> Project: Flink
> Issue Type: New Feature
> Components: Deployment / Kubernetes
> Affects Versions: 1.11.2
> Environment: Kubernetes
> Reporter: Boris Lublinsky
> Priority: Major
> Fix For: 1.12.0, 1.11.2
>
> Original Estimate: 12h
> Remaining Estimate: 12h
>
> A common requirement for Flink applications is usage of custom resources
> (Environment variables, PVCs, Secrets, configMaps, etc). For example, usage
> of NFS-based checkpointing, require mounting NFS volumes, access to databases
> might require environment variables and secrets, the ability to safely remove
> cluster manager deployment might require owner's reference, etc.
> All of these resources can be added to created pods using Pod decorators
> already defined by Flink. So implementation of such support is as simple as
> implementing of new decorators and wiring them correctly to the appropriate
> factories.
>
> An implementation of such support is provided in this pull request
