Application Containers: Kubernetes and Docker from Scratch


In this article we will look at how to configure a Kubernetes cluster using the Docker container format on CentOS or RHEL 7.1. For a detailed overview on Kubernetes and Docker take a look at this article. A Kubernetes cluster is comprised of a master and N nodes. The master acts as a control plane for the cluster and in this case also exposes a private Docker registry. A Kubernetes node runs Docker container images.

Application Containers: A Practical HowTo Guide


We have by now all heard plenty about Linux containers and for good reason. Containers change the way applications are operated and allow us to deploy applications at unprecedented speeds. Containers pick up where Virtual Machines left off, at the application layer. In this article we will focus on the journey to a container driven world and explore the phases along the way.

Containers at Scale with Kubernetes on OpenStack


Containers are a burning hot topic right now. Several open source technologies have come together to allow containers to be operated at scale and in the enterprise. In this article I will talk about these technologies and explain how to build container infrastructure at scale with OpenStack. There are three main components that come together to create container-based infrastructure: Red Hat Enterprise Linux Atomic Host (RHEL Atomic), Docker and Google’s Kubernetes. RHEL Atomic provides an optimized operating system for running containers. Docker delivers container portability and a packaging standard. Kubernetes adds orchestration and management of Docker containers across a massively scalable cluster of RHEL Atomic hosts.
