Known Issue with Docker 1.8 on Oracle Linux 7 Using Firewalld & SELinux with btrfs Storage Driver

(Doc ID 2208037.1)

Last updated on DECEMBER 31, 2016

Applies to:

Linux OS - Version Oracle Linux 7.0 with Unbreakable Enterprise Kernel [3.8.13] to Oracle Linux 7.0 [Release OL7]
Linux x86-64


Docker 1.8 had an issue with firewalld as per

The workaround is to disable either SELinux or firewalld. If you do not disable SELinux to use the btrfs storage engine with Docker, disable firewalld. If you require a system firewall, you can use iptables and ip6tables instead of firewalld.

Does this issue is fixed ?



 With Docker 1.8 On OL7 under and RHCK 3.10 kernels the following issue is observed:

Sep 02 09:57:07 localhost.localdomain docker[1390]: time="2015-09-02T09:57:07.174270885-04:00" level=warning msg="Running modprobe bridge nf_nat br_netfilter failed with message: modprobe: WARNING: Module br_netfilter not found.\n, error: exit status 1"
Sep 02 09:58:36 localhost.localdomain systemd[1]: docker.service operation timed out. Terminating.

In /boot/config-3.8.13-98.2.1.el7uek.x86_64 we have the following options:

so it is not compiled as module and docker trying to load a module would fail as above.
