➦ Installing nova docker on OpenStack Juno
Jan 01, 0001
This post comes about indirectly by a request on IRC in #rdo for help getting nova-docker installed on Fedora 21. I ran through the process from start to finish and decided to write everything down for posterity.
Getting started I started with the Fedora 21 Cloud Image, because I’m installing onto OpenStack and the cloud images include some features that are useful in this environment.
We’ll be using OpenStack packages from the RDO Juno repository.

➦ Integrating Openstack and Kubernetes with Murano
Jan 01, 0001
There’s a perceived competition between OpenStack and containers such as Docker, but in reality, the two technologies are a powerful combination. They both solve similar problems, but on different layers of the stack, so combining the two can give users more scalability and automation than ever before.
That containers app you wrote needs to run somewhere. This is particularly true for orchestrated container applications, such as those managed by Kubernetes. What’s more, if your application is complicated enough that it needs to scale up and down, you need to be running it in an environment that can, itself, scale up and down.

➦ Open vSwitch over DPDK on Ubuntu
Jan 01, 0001
There are two approaches for using DPDK acceleration in DPDK. One is the openvswitch fork from intel, called dpdk-ovs the other is done directly in openvswitch with a different approach from intel. http://dpdk.org/ml/archives/dev/2014-March/001770.html - https://github.com/01org/dpdk-ovs VirtualBox preparations To run openvswitch with DPDK I used a virtual machine (VirtualBox) because the NIC I had on my laptop was not supported. I created three virtual NICs for my vm, one behind NAT
