Description Vivek Goyal 2015-09-02 12:23:10 UTC

Description of problem:

Currently overlayfs does not work with selinux. By default selinux is enabled and if user chooses to use overlay as graph driver, there will be issues.

Modify docker so that it detects this situation during start and fails with appropriate error message.

Sally we already do this for BTRFS, you should just search the code and make the same change.

Comment 3 Sally 2015-09-02 19:56:08 UTC

submitted https://github.com/docker/docker/pull/16025

Comment 4 Vivek Goyal 2015-09-03 13:18:25 UTC

sally, has it been merged into docker we ship in rhel? MODIFIED flag means that patch has been committed in the source tree of redhat rpm.

Comment 5 Vivek Goyal 2015-09-03 13:19:06 UTC

Or rather, an rpm build has been done and rpm is available for testing. Then we will call it MODIFIED.

Comment 6 Sally 2015-09-03 13:32:16 UTC

Sorry for the confusion!  Dan also pointed out my misuse of 'MODIFIED'..
Now I know :)

Comment 7 Sally 2015-09-03 20:35:12 UTC

Comment 8 Daniel Walsh 2015-09-28 18:41:47 UTC

Fixed in docker-1.9

In docker-1.9.1-15.el7.x86_64
