I use Docker a lot. I also use things like Docker volume plugins and have had to modify code due to API changes/breakages. "Production ready" in the "container space" for me are Solaris Zones, FreeBSD Jails, and to an extent lxc (it's stable, but I've used it less). I like what Docker/Mesos/etc. bring to the table, but when working with the ecosystem, it takes work to stay on top of what is going on. It is even harder to consult with a customer or company interested in containers and give the most accurate near/long term option. It becomes a discussion in understanding their application, what approach works now, and guidance for what they should consider down the road. Networking and Storage are two areas with a lot of churn currently.
