Topics on the Merits and Downfalls of Containerization
-
@johnhooks Docker is great for DevOps shows and totally built for them. Zones, Jails and LXC are for big UNIX admins to use for super high performance VMs.

Yup, I have heard that about Rocket but have not had a chance to look at it. Can't wait for the lab to be up!!

It seems like lxc & family are soon to get live migration as well...

Yeah, some definitely will.

I wonder what that will do against Virtualization platforms like XenServer, VMware, et al...
if an lxc-container is functionally equivalent to a VM... Would it be possible to run Windows in an lxc-container... That type of thing.

No, we've had those containers for a decade and we are nowhere near having Windows in them. They all share the parents' kernel by definition. So no Windows coming on Linux containers. Much closer to PV Windows on Xen, at least that has been done in a lab.

So does the container get the same security updates that the host is due for? What if one of those updates is a newer version of the contained application?

What about Containerization on Windows? Didn't OpenVZ or Virtuozzo...used to offer something like that?

No, the DevOps model, and by extension the Docker model, is that the containers never get updates, never change. They are disposable. You replace them, you do not update or maintain them. Same as Devops with Vms.

You can, in theory, make Windows containers on Windows. But you have to be on Windows already.
