Chandni Singh commented on YARN-9378:
-------------------------------------
[~eyang] I attached the patch in which I had created an ImageLocalizer that
executes the DockerImagePull command.
The reason I didn't integrate DockerImagePull command with
LinuxContainerExecutor is because that API is tied to Containers but this
command is independent of containers.
Please take a look at {{ImageLocalizer.java}} class and these methods
- findLocalImages()
- ImageStatusRetriever.run()
Let me know your thoughts.

> {{LinuxContainerExecutor}} is for container operations. DockerImagesCommand
> is independent of any container. The image localizer acts as a service that
> will localize docker images and maintain an image cache. Other components can
> use this to query about the images on the node.
