Bug ID: 1033606
Summary: Failed to connect to network from Docker container
Product: Fedora
Version: 20
Component: docker-io
Assignee: lsm5(a)redhat.com
Reporter: mfojtik(a)redhat.com
QA Contact: extras-qa(a)fedoraproject.org
CC: golang(a)lists.fedoraproject.org, lsm5(a)redhat.com,

Description of problem:
Connecting to external network from Docker container fail due to firewalld. I
guess you must have masquerade enabled, however this is not mentioned anywhere.
I think docker-io should set the firewalld rules automatically, or tell users
that they need to enable masquarade in firewalld.
Version-Release number of selected component (if applicable):
Name : docker-io
Arch : x86_64
Version : 0.7
Release : 0.17.rc6.fc20
Steps to Reproduce:
1. $ yum install docker-io
2. $ systemctl enable docker.service
3. $ systemctl start docker.service
4. $ docker pull mattdm/fedora
5. $ docker run -i -t mattdm/fedora:latest /bin/bash
6. $ ping
google.com
ping: unknown host
google.com
When I stop firewalld on host (systemctl stop firewalld) and then restart the
docker (systemctl restart docker), the ping works like a charm.
Actual results:
Unable to connect outside the Docker container with firewalld enabled.
Expected results:
Docker should configure firewalld automatically (during install?), or inform
users to do so manually.
