|Desc=Docker is making a lot of waves in open source communities. There are really two functional aspects to Docker: |
|||
* Linux Containers as lightweight hypervisor (with all the security drawbacks) |
|||
* Application Containers as a packaging and deployment format - this part is really exciting as it is a ''gamechanger in application design, system deployment, and, critically, versioning''. Slides 1-15 of [http://www.slideshare.net/dotCloud/docker-intro-november] make this case quite compellingly. |
|||
What is not clear is how tightly the two are coupled and interdependent. I heard (but can't find references) that there are, or it is possible to write '''Docker Engines''' for other hypervisors. At least in theory. |
|||
Now, if you look at [http://www.slideshare.net/dotCloud/docker-intro-november/16 slide 16], you notice that the architecture diagram is very similar to a Xen based system with service domains, driver domains, and the likes of Mirage OS, OSv, ErlangOnXen (also see Voxoz which seem to be working on something similar), ... BUT: of course we have the added benefits of isolation and thus more security and the flexibility of running traditional fully fledged VMs with different Guest OS’es on the same host. |
|||
At least in theory, this should make it possible to use the deployment capabilities of Docker to deploy service domains, Mirage OS & friends. If this was possible and could be implemented easily we could be in for a winner. Aka getting all the benefits for the deployment part of Docker, while not suffering any of the drawbacks. And we could piggyback onto the Docker hype. Of course I don’t know whether this is technically feasible at all and how hard it would be to do this. |
