[jira] [Comment Edited] (FLINK-15656) Support user-specified pod
templates
[ https://issues.apache.org/jira/browse/FLINK-15656?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17077827#comment-17077827 ]

---------------------------------------------------------------
>> I think it makes sense to me to provide a basic init container to download the user jars and dependencies. At the very beginning, we could leverage the {{FileSystem}} in Flink to support to download from HDFS, S3, OSS, etc. Since [~ouyangwuli] wants to work on this, what do you think about this?
Glad that [~ouyangwuli] would work on the built-in init container implementation. Our internal branch has supported this feature, and I could help review the design, code, and test.
>> [~felixzheng] Do you mind to move this ticket as a subtask of FLINK-14460 for easier tracking?
Actually I am not very sure that the pod template feature could be merged into release 1.11.0. Moreover, this ticket needs a design doc and discussion in the dev mailing list, so I tend to leave it alone instead of being a subtask of FLINK-14460

> Project: Flink
> Issue Type: New Feature
> Components: Deployment / Kubernetes
> Reporter: Canbin Zheng
> Priority: Major
>
> The current approach of introducing new configuration options for each aspect of pod specification a user might wish is becoming unwieldy, we have to maintain more and more Flink side Kubernetes configuration options and users have to learn the gap between the declarative model used by Kubernetes and the configuration model used by Flink. It's a great improvement to allow users to specify pod templates as central places for all customization needs for the jobmanager and taskmanager pods.
