Rootconf 2014

Understand what Linux containers are and how to package a given software using them. We would use docker (https://www.docker.io) to do that.

Outline

I am sure you would have faced the problem when an app you write does work on your environment but does not work on your client’s, co-worker’s or other environment. It may be because of some dependent software, configuration etc. How about if we can put all dependencies, configurations in a container and run it on different environment. Looks interesting .. the Linux containers are here to help you.

LXC ( Linux container) provides operating system-level virtualization not via a virtual machine, but rather provides a virtual environment that has its own process and network space. And Docker (https://www.docker.io) is a project automating deployment of applications inside software containers.

We would use docker to package some applications and run it on different environment.

Requirements

Linux distribution with kernel > 3.8
For RHEL, kernel > 2.6.32-431
