Yang Wang commented on FLINK-15641:
-----------------------------------
[~ouyangwuli] If you want to work on the init-container and sidecar container,
could you please draft a design doc? I think it needs to include the following
sections.
* The motivation of introducing these two containers
* How does it work
* How to debug the network problems, collect logs, etc. with sidecar container
* Pod lifecycle and restart policy when it has more than one container
* Implementation guideline
[~felixzheng] Feel free to add more information about the doc.

> >> Why do we need init container?
> The init container could be used to prepare the use jars and dependencies.
> Then we could always set the user image to Flink official image both for
> standalone per-job on K8s or native K8s per-job. When the JobManager and
> TaskManager container launched, the user jars will already exist there. I
> think many users are running standalone per-job cluster in production by
> using this way.
> The init container only works for K8s cluster.
