Eric Yang commented on YARN-5670:
---------------------------------
The current proposal is to have a configuration flag to enable a background
image clean up thread. The image clean up thread wakes up every 4 hours to
remove docker images that has not been used in the last 24 hours. Docker
command to run is:
{code}
docker image prune -a --filter "until=24h" -f
{code}
> Add support for Docker image clean up

> Key: YARN-5670
> URL: https://issues.apache.org/jira/browse/YARN-5670
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: yarn
> Reporter: Zhankun Tang
> Assignee: Eric Yang
> Priority: Major
> Labels: Docker

> Regarding to Docker image localization, we also need a way to clean up the
> old/stale Docker image to save storage space. We may extend deletion service
> to utilize "docker rm" to do this.
> This is related to YARN-3854 and may depend on its implementation. Please
> refer to YARN-3854 for Docker image localization details.
