liuzhuo updated FLINK-24321:
----------------------------
Issue Type: New Feature (was: Improvement)
> The Pod Template supports replaceable content
> ---------------------------------------------
>
> Key: FLINK-24321
> URL: https://issues.apache.org/jira/browse/FLINK-24321
> Project: Flink
> Issue Type: New Feature
> Components: Deployment / Kubernetes
> Reporter: liuzhuo
> Priority: Minor
>
> For the current use of pod template, if you want to perform some different
> configurations for each task, you can only modify the pod template file at
> present
> For example, if I want to mount the JM/TM log to the host for subsequent
> viewing, the following configuration will cause the file to be overwritten
> (the host's /data/log directory)
>
> {code:java}
> name: flink-log-volume
> hostPath:
> path: /data/log/
> type: DirectoryOrCreate{code}
>
> At present, it can only be solved by modifying the pod template. Should we
> provide a simpler way to use wildcard replacement to make runtime
> modifications, such as:
> {code:java}
> name: flink-log-volume
> hostPath:
> path: /data/log/${ClusterId}/
> type: DirectoryOrCreate{code}
>
> When constructing the pod, replace specific values, such as commonly used
> values such as ${ClusterId} and ${FlinkJobId}, or replace it with the
> configuration value of “org.apache.flink.configuration.Configuration”, such
> as "kubernetes.pod.temeplate. replace.jobmanager.UserId" = "100", this will
> automatically replace the value of ${UserId} in JM POD with 100
