This is one of the tailored ones — Docker host ready to go. '''Importance:''' moderate (Docker is hot stuff and we need an answer to CoreOS, but if we fail to do it, we are not any worse-off than we are now, and Docker can still be used on the base iamge.) '''Timeframe:''' F21 alpha / If it's not ready for alpha, we have missed this release '''Scope:''' system-wide''' '''Cloud SIG owner:''' Sandro Mathys https://fedoraproject.org/wiki/Changes/Docker_Cloud_Image N.B. We may consider Fedora Atomic Initiative for this image, depending on degree of effort on that project across the rest of Fedora. -- -- Ticket URL: <https://fedorahosted.org/cloud/ticket/19#comment:1> cloud <https://fedorahosted.org/cloud> Fedora Cloud Working Group Ticketing System

Since the change deadline is coming up real soon now, we really need to make all of those decisions ASAP. Status at last meeting some 2 or 3 weeks ago was: need input from Heat people first. -- Ticket URL: <https://fedorahosted.org/cloud/ticket/19#comment:3> cloud <https://fedorahosted.org/cloud> Fedora Cloud Working Group Ticketing System

Status at last meeting some 2 or 3 weeks ago was: need input from Heat people first. https://lists.fedoraproject.org/pipermail/cloud/2014-March/003398.html tools in the image. Yes, we do. I was more trying to say where the discussion of the above- mentioned points stopped, and why. With that input, we need to decide whether we want go that path. Do we want to force users to use the (contrib-only / non-supported) docker driver? Not sure it's available to users of OpenStack public clouds (HP, Rackspace, ...) at all. And if we do, there's still all those other decisions to be made. -- Ticket URL: <https://fedorahosted.org/cloud/ticket/19#comment:5> cloud <https://fedorahosted.org/cloud> Fedora Cloud Working Group Ticketing System

#19: File F21 change: Docker Host Image -------------------------------+------------------------------------------- Reporter: mattdm | Owner: red Type: task | Status: accepted Priority: blocker | Milestone: Fedora 21 (Feature Deadline) Component: Docker Host Image | Resolution: Keywords: | -------------------------------+------------------------------------------- Comment (by red): While I agree we can make this one very special purpose and radical, I'm just not sure ostree is there yet. I know, we want to adopt it early on and I love to ride the leading edge but I currently think we lack the capacity and it's not crucial to the image / mission. We do have a lot on our plates and activity in the WG / SIG is faltering. So my opinion tends slightly towards "keep things close to how they were in F20 and focus on the new products and low hanging fruits like smaller footprint and systemd-networkd". That obviously includes sticking with yum/dnf and python for now. Also, getting rid of cloud-init (or rather, all its dependencies etc.) would be nice but min-metadata-service isn't ready (and I'm not fully convinced radically minimal is great here). Unfortunately, I didn't have time to pay a closer look to coreos' solution either but I figure it isn't in Fedora yet anyway, so getting it in might take too long. So since we didn't have a meeting in a while and I'd rather not formulate a change proposal with lots of undecided things/options, I hope more people (voting members and others) can weigh in here or on the ml. -- Ticket URL: <https://fedorahosted.org/cloud/ticket/19#comment:7> cloud <https://fedorahosted.org/cloud> Fedora Cloud Working Group Ticketing System

Well, also, since we were speaking about docker and SELinux - is it still necessary with ostree to disable SELinux to boot into a tree as outlined in the [http://rpm-ostree.cloud.fedoraproject.org/#/installation installation guide]? Obviously, that would be a major show stopper. -- Ticket URL: <https://fedorahosted.org/cloud/ticket/19#comment:13> cloud <https://fedorahosted.org/cloud> Fedora Cloud Working Group Ticketing System

Anything you need from us to go on from here? Not currently. The hardest thing will be handling of volumes with SELinux.

Obviously, that would be a major show stopper. Nope, that's been fixed for quite a while. I updated the web page. The qcow2 images you download are in enforcing mode. Anaconda will install in enforcing mode. Now, using OSTree to *parallel install* is a trickier case, but should be fixed by https://bugzilla.redhat.com/show_bug.cgi?id=1061064 -- Ticket URL: <https://fedorahosted.org/cloud/ticket/19#comment:17> cloud <https://fedorahosted.org/cloud> Fedora Cloud Working Group Ticketing System

Or should I create a new one with the meeting keyword? @scollier: Right now, IMHO: - Wait for FESCo's approval - Make some crucial decisions (see comment 4) - Wait for image building with Anaconda to become available in Koji - Wait for the base image to be adopted to Anaconda (unless we go with ostree, I guess) So best things to do right now is to get familiar with all the bits and pieces (anaconda's image building, kernel-core, ostree, docker, etcd, fleet, whatever else you think should possibly be included in the Docker host image) and possibly form an opinion to support the decision making. -- Ticket URL: <https://fedorahosted.org/cloud/ticket/19#comment:19> cloud <https://fedorahosted.org/cloud> Fedora Cloud Working Group Ticketing System
