Eric Yang commented on YARN-9239:
---------------------------------
Quote from [~anu]'s mail:

The CSI interface does not have the write back capability yet. You might want
to use S3 protocol -- that way you can read and write to the bucket if needed.
--Anu
We need to switch to another CSI driver that supports writes, but that is
something we need to get to.

There are more work on Ozone side to enable proper writeback capabilities.
This is not the right time to document how Ozone CSI driver to work with Docker
registry. Therefore, I will remove Docker Registry + CSI driver documentation
for now.

> Priority: Major
>
> Another approach to mount Docker registry storage can be done at file system
> layer. The deployment can use YARN CSI driver to mount Ozone volume into
> docker registry container. This provides alternate approach to YARN-9229 for
> getting Docker registry to use distributed filesystem as backend storage.
> This task is to study the performance of deploying docker registry with Ozone
> CSI driver.
