Description Subhendu Ghosh 2015-10-20 18:40:48 UTC

Description of problem:
https://github.com/docker/docker/issues/17190

Docker 1.8 has a race condition and can corrupt /etc/hosts inside a container 

Google is coordinating a temp fix for the distros since upstream is pushing the issue out to upstream 1.9 for a fix.


Expected results:

Comment 1 Daniel Walsh 2015-10-20 18:49:21 UTC

As soon as they have a fix, we can patch this, but I am not sure if we are releasing anything before we ship docker-1.9?

Comment 2 Daniel Walsh 2015-10-28 17:26:34 UTC

Looks like googles fix will be outside of docker.

So we can say this is partially fixed in docker-1.9. With more fixes coming in docker-1.10.

Comment 3 Daniel Walsh 2016-01-06 19:45:55 UTC

Fixed in docker-1.10

Comment 5 Luwen Su 2016-02-03 09:29:54 UTC

In docker-1.9.1-15.el7.x86_64,
use this https://github.com/docker/docker/issues/17190#issuecomment-149437458,
the file looks good
# docker exec test-master cat /etc/hosts
172.17.0.2	f988d8d83483
127.0.0.1	localhost
::1	localhost ip6-localhost ip6-loopback
fe00::0	ip6-localnet
ff00::0	ip6-mcastprefix
ff02::1	ip6-allnodes
ff02::2	ip6-allrouters

Comment 6 Lokesh Mandvekar 2016-02-03 15:53:20 UTC

i'm moving this back to MODIFIED as per Dan's comment and scheduling this for 1.10 update.

Comment 9 Lokesh Mandvekar 2016-04-19 16:10:37 UTC

changing component to docker-latest

Comment 11 Alex Jia 2016-04-29 10:50:18 UTC

It works well on docker-latest-1.10.3-19, so moving the bug to VERIFIED status.
