Eric Yang created YARN-7446: ------------------------------- Summary: Docker container privileged mode and --user flag contradict each other Key: YARN-7446 URL: https://issues.apache.org/jira/browse/YARN-7446 Project: Hadoop YARN Issue Type: Bug Affects Versions: 3.0.0 Reporter: Eric Yang
In the current implementation, when privileged=true, --user flag is also passed to docker for launching container. In reality, the container has no way to use root privileges unless there is sticky bit or sudoers in the image for the specified user to gain privileges again. To avoid duplication of dropping and reacquire root privileges, we can reduce the duplication of specifying both flag. When privileged mode is enabled, --user flag should be omitted. When non-privileged mode is enabled, --user flag is supplied. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
