It's based off of [~tangzhankun]'s initial patch. It allows a user to specify for them to use their UID:GID pairing instead of their username when entering a container. Additionally, it uses --group-add to add the rest of their groups. Review and comments would be much appreciated! > Allow whitelisted users to disable user re-mapping/squashing when launching docker containers > --------------------------------------------------------------------------------------------- > > Key: YARN-4266 > URL: https://issues.apache.org/jira/browse/YARN-4266 > Project: Hadoop YARN > Issue Type: Sub-task > Components: yarn > Reporter: Sidharta Seethana > Assignee: luhuichun > Attachments: YARN-4266.001.patch, YARN-4266.001.patch, YARN-4266.002.patch, YARN-4266_Allow_whitelisted_users_to_disable_user_re-mapping.pdf, YARN-4266_Allow_whitelisted_users_to_disable_user_re-mapping_v2.pdf, YARN-4266_Allow_whitelisted_users_to_disable_user_re-mapping_v3.pdf, YARN-4266-branch-2.8.001.patch > > > Docker provides a mechanism (the --user switch) that enables us to specify the user the container processes should run as. We use this mechanism today when launching docker containers . In non-secure mode, we run the docker container based on `yarn.nodemanager.linux-container-executor.nonsecure-mode.local-user` and in secure mode, as the submitting user. However, this mechanism breaks down with a large number of 'pre-created' images which don't necessarily have the users available within the image. Examples of such images include shared images that need to be used by multiple users. We need a way in which we can allow a pre-defined set of users to run containers based on existing images, without using the --user switch. There are some implications of disabling this user squashing that we'll need to work through : log aggregation, artifact deletion etc., -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: yarn-issues-help@hadoop.apache.org
