Summary: Add a flag to use local docker image instead of getting
latest from registry
Key: YARN-8955
URL: https://issues.apache.org/jira/browse/YARN-8955
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Eric Yang
Some companies have security policy to use local docker images instead of
getting latest images from internet. When docker image is pulled in
localization phase, there are two possible out comes. The image is getting the
latest from trusted registries, or the image is a static local copy. This task
is to add a configuration flag to give priority to local image over trusted
registry image.
If a image already exist locally, node manager does not trigger docker pull to
get the latest image from trusted registries.
