[Bug 1185423] New: MountFlags=private in docker.service prevents admin from exposing new storage to docker
by Red Hat Bugzilla 04 Feb '15

04 Feb '15

https://bugzilla.redhat.com/show_bug.cgi?id=1185423 Bug ID: 1185423 Summary: MountFlags=private in docker.service prevents admin from exposing new storage to docker Product: Fedora Version: 21 Component: docker-io Assignee: lsm5(a)redhat.com Reporter: lars(a)redhat.com QA Contact: extras-qa(a)fedoraproject.org CC: adimania(a)gmail.com, admiller(a)redhat.com, golang(a)lists.fedoraproject.org, hushan.jia(a)gmail.com, jchaloup(a)redhat.com, jperrin(a)centos.org, lsm5(a)redhat.com, mattdm(a)redhat.com, mgoldman(a)redhat.com, miminar(a)redhat.com, s(a)shk.io, thrcka(a)redhat.com, vbatts(a)redhat.com Setting MountFlags=private in docker.service means that any storage mounted on the host after starting Docker will be unavailable for docker containers. For example, I wanted to expose a directory from a remote server to a Docker container: mkdir /data/content mount remote-server:/vol/content /data/content docker run -v /data/content:/content larsks/thttpd -d /content This fails because Docker does not see the mount onto /data/content. It only sees the content of the underlying directory, not the mounted filesystem. I think we want MountFlags=slave instead, which would prevent mounts inside the Docker mount namespace from propagating to the global namespace while still allowing global mounts to be available to docker containers. -- You are receiving this mail because: You are on the CC list for the bug.

golang deps (rpms v/s bundled)
by Lokesh Mandvekar 03 Feb '15

03 Feb '15

Hi all, I propose to prefer using vendored/bundled golang deps and use rpm dependencies only as a last resort for golang packages. Short story long: quite a few golang packages like docker, kubernetes and (hopefully soon) rocket provide a dir like 'vendor/' or 'Godeps/' which includes the golang dependencies used, thus making rpm dependencies redundant IMO. Using the bundled sources makes building packages a lot more convenient than depending on rpms. I'm aware that the dependencies are different upstreams but since those are bundled along with the main tool, perhaps we can relax that restriction. As most of you may have already experienced, golang deps are a huge PITA to update/use in docker/kube though props to jchaloup on making golang packaging very easy: https://github.com/ingvagabund/GolangPackageGenerator All that said, we could still continue to package golang repos in case someone needs it for something. I was hoping we could yay or nay on this and also perhaps modify the golang packaging draft if everyone agrees. https://fedoraproject.org/wiki/PackagingDrafts/Go#Dependencies Comments? PS: I'm doing this already for daily rebuilds of docker master branch on fedora rawhide starting today. -- Lokesh Freenode, OFTC: lsm5 GPG: 0xC7C3A0DD
