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?

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.

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.

I think so. Docker originated from a wrapper for lxc, which is for me a
bigger form of a chroot jail :)
