Hello,

I'm sure some of you already know about this, but I'd just like to formally invite everyone to the first Prague Docker meetup, which will take place at Brmlab on 9.6.2014 at 18:00.

In case you guys don't already know, Docker is a new tool for creating portable chrooted environments.  It allows anyone to create a portable Docker image(a tarball with a file tree that looks like the root fs of a normal linux install).  A program installed within the image can be run flawlessly on any 64 bit linux system which supports Docker. That means that if I can install a program on Debian, than I can package that program up in a docker image and run that program on Fedora.  Better yet, the program is confined to it's chrooted environment using Linux's cgroups, meaning that you can safely try out programs that you do not trust.

This leads to a virtual machine like tool that is unbelievably light weight.  Programs installed in Docker images can be run with no more overhead* than any other linux process.

If you want to find out more about Docker, or if you are already involved and interested in the software, please join us!

(*) There may be a very slight ram penalty due to an inability to share dynamically linked libraries.
