Eric Badger commented on YARN-7516: ----------------------------------- bq. Eric Badger We can go with remove --prilvileged, and allow the container to run like you recommended. We won't be able to run systemd or supervisor from untrusted source for now. This is better than open up too much. That sounds good to me. We can always open it up a little bit more later. But I'd rather the user not accidentally open up docker without understanding what they did. Especially with an image from an untrusted registry. > Security check for untrusted docker image > ----------------------------------------- > > Key: YARN-7516 > URL: https://issues.apache.org/jira/browse/YARN-7516 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Eric Yang > Assignee: Eric Yang > Attachments: YARN-7516.001.patch, YARN-7516.002.patch, > YARN-7516.003.patch, YARN-7516.004.patch, YARN-7516.005.patch, > YARN-7516.006.patch, YARN-7516.007.patch > > > Hadoop YARN Services can support using private docker registry image or > docker image from docker hub. In current implementation, Hadoop security is > enforced through username and group membership, and enforce uid:gid > consistency in docker container and distributed file system. There is cloud > use case for having ability to run untrusted docker image on the same cluster > for testing. > The basic requirement for untrusted container is to ensure all kernel and > root privileges are dropped, and there is no interaction with distributed > file system to avoid contamination. We can probably enforce detection of > untrusted docker image by checking the following: > # If docker image is from public docker hub repository, the container is > automatically flagged as insecure, and disk volume mount are disabled > automatically, and drop all kernel capabilities. > # If docker image is from private repository in docker hub, and there is a > white list to allow the private repository, disk volume mount is allowed, > kernel capabilities follows the allowed list. > # If docker image is from private trusted registry with image name like > "private.registry.local:5000/centos", and white list allows this private > trusted repository. Disk volume mount is allowed, kernel capabilities > follows the allowed list. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
