In this post I will describe the steps I followed to be able to install (with openshift-ansible playbooks), test and play with an OpenShift deployment with Kuryr SDN on top of a developer OpenStack environment built using a DevStack multi node running on 3 VMs. I will cover the next steps: Creation of the 3 … Continue reading Deploying OpenShift with Kuryr on a DevStack multi node environment
As motivated in previous blog posts (Superfluidity series: https://ltomasbo.wordpress.com/2017/01/16/superfluidity-containers-and-vms-at-the-mobile-network-part-1/) there is a need to handle both containers and VMs at the Edge Clouds. There are several reasons to do so, among others: VMs are more secure than containers, but containers are faster to boot up and quick reaction is needed at the edge, but so … Continue reading OpenShift with Kuryr on top of OpenStack VMs: step by step set up
As described in the previous blog post series: "Superfluidity: Containers and VMs in the Mobile Network" (https://ltomasbo.wordpress.com/2017/01/16/superfluidity-containers-and-vms-at-the-mobile-network-part-1/), kuryr enables both side-by-side and nested kubernetes and OpenStack deployments, where containers can be created and connected to Neutron networks either on baremetal hosts or inside OpenStack VMs. One of the main advantages that containers offer over VMs … Continue reading Kuryr Ports Pool: Speeding up containers booting time on Neutron networks
Kuryr enables both side by side Kubernetes and OpenStack deployments, as well as nested ones where Kubernetes is installed inside OpenStack VMs. As highlighted in previous posts, there is nothing that precludes having a hybrid deployment, i.e., both side by side and nested containers at the same time. Thanks to Kuryr, a higher flexibility for the … Continue reading Side-by-side and nested Kubernetes and OpenStack deployment with Kuryr
Once we have the ‘glue’ between VMs and containers as presented in the previous blog post (https://ltomasbo.wordpress.com/2017/01/16/superfluidity-containers-and-vms-at-the-mobile-network-part-1/), an important decision is what type of deployment is most suitable for each use case. Some applications (MEC Apps) or Virtual Network Functions (VNFs) may need really fast scaling or spawn responses and require therefore to be run directly … Continue reading Superfluidity: Containers and VMs deployment for the Mobile Network (Part 2)
