Not to the best of my knowledge, but afaik modules could be containers and/or optionally be distributed as such. > >> > And any guidelines on naming? Just use common sense?

The web server name? A > combo? So a question around this topic has come up recently on IRC, I was hoping to see it make it to the mailing list but it has not. Something we've not yet addressed yet and that we really need to, is how to handle multi-service containers *OR* multi-container services (I was secretly hoping to have a Container Guidelines SIG exist that could hash this out). Providing an all-in-one docker image is certainly something we can do such that the container image provides web server + database + web app, but it seems more popular to have each element (server, database, app) be placed into it's own container and have them be "wired" together via some tooling. There's many examples of open source multi-container orchestration solutions[0][1][2][3][4][5][6] (and likely others I'm not familiar with). Also, the Project Atomic upstream group has an open specification for how to define these multi-container services called Nulecule[7] that is meant to be independent of the backend implementation of container orchestration engine but simply a definition template/spec which is something I'd also like to see considered. As a side note, there's a reference implementation of the Nulecule spec called Atomic App[8] that might also be worth while for consideration from the group on the topic. > >> > I guess the build system has network access and people can put >> > anything in CMD lines?

This is true and is probably something we should address in the near term.

There's still plenty to be considered around all of this, looking forward to continued feedback from everyone. :) -AdamM [0] - https://www.openshift.com [1] - http://kubernetes.io/ [2] - https://github.com/docker/swarm [3] - https://github.com/docker/compose [4] - https://dcos.io/ [5] - http://deis.io/ [6] - https://www.cloudfoundry.org/ [7] - https://github.com/projectatomic/nulecule [8] - https://github.com/projectatomic/atomicapp > > kevin > > > > -- > devel mailing list > devel@lists.fedoraproject.org > http://lists.fedoraproject.org/admin/lists/devel@lists.fedoraproject.org > -- devel mailing list devel@lists.fedoraproject.org http://lists.fedoraproject.org/admin/lists/devel@lists.fedoraproject.org
