As I had said earlier (just last week) in this list, FreeBSD is a great platform for the near expert unix user, and there are many reasons for it. ZFS was very recently added, and ZFS itself is under constant development, so anyone going down that path is really almost on their own when it comes to solving problems. Having said that, I confess that I just heard of Docker at the last Penguins meeting (thanks Lloyd) and as a Linux user I err on the side of LXC/LXD. I certainly cannot advise on what is a good path forward with BSD over Docket or even LXC. However, I am interested to follow on your experience (both for Docker <-> FreeBSD and ZFS) and light-weight OSs for deploying containers. Whether it is Atomic, Xen, LXC, Docket and combinations of those container infrastructures and hypervisiors, I am after a very transparent virtualization solution, about which I should not try to elaborate on this list but I welcome questions over personal email. And here is my question. I need an answer to this question: https://lists.linuxcontainers.org/pipermail/lxc-users/2016-March/011188.html I have emailed the OP and have got no response on their experience. I am interested in pushing Infiniband transparently (to do RDMA from within the container to other containers). If that can be done, I am buying you a lot of beer.
