People,
We are proud to announce official Docker containers for our latest openSUSE release, 13.1. Docker is an open-source project that automates the deployment of applications inside software containers. With the official openSUSE Docker containers it’s now easy for developers to leverage the power of our Linux distribution and it’s free software Eco-system as base for their applications.
Henne, all, OK, I've done the docker tutorial and it looks like an encapsulation of git applied to this amorphous development framework, etc. Before devoting the precious few remaining brain-cells I have to digging further into docker, what is it built on/of? What are the performance comparisons between a docker app and an equivalent C app? Are we talking BASH performance, PERL performance, Java performance, C++ performance or C/asm (unlikely)? Container storage size?? I was a bit shocked to see the tutorial weighing in at 130+Meg and the push upload (simulation) of my 'ping' app at 11.5+Meg (compared to 7k for a stripped C executable, 32 bytes for a comparable BASH script [including #!/bin/bash]). Where is a good place to get a good idea of these comparisons? -- David C.

WUT ? a docker app is nothing more than a packaging format for the container image..it has nothing to do with the language the application itself is written on..

That's pretty small.. The whole point of the exercise is running this "ping" app in an isolated, predefined, restricted environment.. for that you need a bare bones OS inside the container. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

In this case a "ping" binary, requires glibc, which itself requires "filesystem" and whatever other elementary component required for "ping" to install. the kernel is however shared with the host system. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

so may be assume this is sort of chroot sytem in a package? thanks jdd -- http://www.dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I think so. Docker originated from a wrapper for lxc, which is for me a bigger form of a chroot jail :) Werner -- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
