Very exciting to see multiple App Container Spec implementations showing up this quickly!<p>> This last week has also seen the emergence of two different implementations of the spec: jetpack (a FreeBSD/Jails-based executor) and libappc (a C++ library for working with app containers). The authors of both projects have provided extremely helpful feedback and pull requests to the spec, and it is great to see these early implementations develop!<p>I think this is really telling of a great (and necessary) thing. Standardizing a container specification was long overdue; a standard and portable app container spec will really propel containerization to the next level.
"we've taken care to implement these lifecycle-related subcommands without introducing additional daemons or databases" oh I love you rocket. I mean, I'd be scared to implement that myself (FS based concurrency control always seems hellish), but I guess that's the joy of ACI; I can just use another implementation if you scare me too much.<p>Reading the signing and verification stuff, the section on "Distributing Images via Meta Discovery" reminded me of my personal dream: bittorrent based distribution. How hard would this be? Seeing as the ACI tarballs seem to be just stored on disk, would it simply be a case of telling my bittorrent client to dump all my ACIs in some folder and then getting rocket to look there? Or is there a need to write some kind of rocket plugin for that kind of thing?
We just published a conversation with Alex Polvi (CoreOS CEO) all about Rocket and the App Container Spec. Check it out if you want to hear more:<p><a href="http://thechangelog.com/138" rel="nofollow">http://thechangelog.com/138</a>
Another announcement about containers went largely unnoticed: Ubuntu released Ubuntu Core, a Ubuntu variant optimized for cloud and IoT security. But the documentation and developer adoption seems to be behind CoreOs currently.<p>I haven't done anything with CoreOs yet, but from my personal feeling I'd prefer Ubuntu over something that is based on Gentoo. I may be completely wrong on this though.
Here's the open specification for Docker's standard format: <a href="https://github.com/docker/docker/blob/master/image/spec/v1.md" rel="nofollow">https://github.com/docker/docker/blob/master/image/spec/v1.m...</a>
