Prabhu Joseph updated YARN-9860: -------------------------------- Attachment: YARN-9860-008.patch > Enable service mode for Docker containers on YARN > ------------------------------------------------- > > Key: YARN-9860 > URL: https://issues.apache.org/jira/browse/YARN-9860 > Project: Hadoop YARN > Issue Type: Improvement > Affects Versions: 3.3.0 > Reporter: Prabhu Joseph > Assignee: Prabhu Joseph > Priority: Major > Attachments: Screen Shot 2019-10-09 at 11.27.19 AM.png, > YARN-9860-001.patch, YARN-9860-002.patch, YARN-9860-003.patch, > YARN-9860-004.patch, YARN-9860-005.patch, YARN-9860-006.patch, > YARN-9860-007.patch, YARN-9860-008.patch > > > This task is to add support to YARN for running Docker containers in "Service > Mode". > Service Mode - Run the container as defined by the image, but still allow for > injecting configuration. > Background: > Entrypoint mode helped - now able to use the ENV and ENTRYPOINT/CMD as > defined in the image. However, still requires modification to official images > due to user propagation > User propagation is problematic for running a secure cluster with sssd > > Implementation: > Must be enabled via c-e.cfg (example: docker.service-mode.allowed=true) > Must be requested at runtime - (example: > YARN_CONTAINER_RUNTIME_DOCKER_SERVICE_MODE=true) > Entrypoint mode is default enabled for this mode (If Service Mode is > requested, YARN_CONTAINER_RUNTIME_DOCKER_RUN_OVERRIDE_DISABLE should be set > to true) > Writable log mount will not be added - stdout logging may still work > with entrypoint mode - remove the writable bind mounts > User and groups will not be propagated (now: docker run --user nobody > --group-add=nobody .... <image>, after: docker run .... <image>) > Read-only resources mounted at the file level, files get chmod 777, > parent directory only accessible by the run as user. > cc [~shaneku...@gmail.com] -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
