[Bug 1033606] New: Failed to connect to network from Docker container
by Red Hat Bugzilla 17 Jun '15

17 Jun '15

https://bugzilla.redhat.com/show_bug.cgi?id=1033606 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, mattdm(a)redhat.com, mgoldman(a)redhat.com, vbatts(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.

https://bugzilla.redhat.com/show_bug.cgi?id=1160833 Bug ID: 1160833 Summary: Fedora 21 Beta Atomic Image: broken links, incomplete documentation, missing "docker" executable Product: Fedora Version: 21 Component: docker-io Severity: high Assignee: lsm5(a)fedoraproject.org Reporter: znmeb(a)znmeb.net QA Contact: extras-qa(a)fedoraproject.org CC: admiller(a)redhat.com, golang(a)lists.fedoraproject.org, hushan.jia(a)gmail.com, jperrin(a)centos.org, lsm5(a)fedoraproject.org, mattdm(a)redhat.com, mgoldman(a)redhat.com, miminar(a)redhat.com, s(a)shk.io, thrcka(a)redhat.com, vbatts(a)redhat.com Description of problem: Multiple problems with Fedora 21 Beta Atomic Image: broken links, incomplete documentation, missing "docker" executable Version-Release number of selected component (if applicable): Atomic Images beta Steps to Reproduce: 1. Browse to http://fedoraproject.org/en/get-prerelease#cloud. 2. Attempt to download and discover broken link to qcow2 and raw disk images on the beta release page. 3. Find, download, verify checksum of images at http://mirror.pnl.gov/fedora/linux/releases/test/21-Beta/Cloud/Images/x86_6… 4. Prepare an initialization ISO file as described in http://www.projectatomic.io/docs/quickstart/ and https://www.technovelty.org//linux/running-cloud-images-locally.html. Note that said documentation a. Is *not* part of the Fedora documentation, which is something I expect for something carrying the "Fedora Cloud" brand, and b. Nowhere is it *explicitly* stated that the username is "fedora" or that once you log in as "fedora", "sudo su -" works to get you into "root" on the console. 5. Log in as "fedora", type "sudo su -" and type "docker ps". Actual results: '-bash: docker: command not found' Expected results: 1. Working links on the beta release page 2. Fedora-branded documentation with the username and how to obtain root. 3. Docker installed and ready to create images and containers. -- You are receiving this mail because: You are on the CC list for the bug.
