ELO: Openshift Atomic Cluster (OAC)

version 1.5

The OpenShift Atomic Cluster uses OpenShift Origin, the upstream opens source fork of the Red Hat OpenShift Container Platform (OCP). 

OpenShift Origin is a containerized application platform with a native Kubernetes integration.

OpenShift Origin is the premier Platform-as-a-Service (PasS) that is developer-oriented. 










The containerized Origin masters, etcd, the
nodes and the Traefik Ingress Controller (or  edge router ) or the optional F5 Kubernetes Big-IP Controller are all running on CentOS 7 Atomic virtual machines (VM) on KVM hosts.  Digital Certificates are automatically installed and renewed for any Internet-exposed services using the Let's Encrypt (LE) ACME Protocol.

Rapidly deploy OpenShift templates to the OpenShift Atomic Cluster, to bring up an application with dynamically-provisioned storage, with a few clicks. 



Traefik Load Balancer 

Traefik (pronounced like traffic) is a modern HTTP reverse proxy and load balancer made to deploy production-ready microservices with ease. It supports several backends like Kubernetes, Docker, and Swarm to manage its configuration automatically and dynamically.

Traefik will listen to the Kubernetes orchestration API, and knows each time a microservice is added, removed, killed, or upgraded, and will generate its configuration automatically. Routes to OAC services will be created instantly.


Hyper-Converged GlusterFS Cluster

The OpenShift Atomic Cluster deployment delivers a hyper-converged solution. The designated, or labeled. storage nodes host the 'gluster-centos' pods that also co-reside with other application pods to provide the ultimate in hardware utilization. The GlusterFS Cluster is managed by Heketi.

Containerized F5 Big-IP Controller 






The F5 Kubernetes BIG-IP Controller configures BIG-IP Local Traffic Manager (LTM) objects for applications in the OpenShift Atomic Cluster  (OAC) , serving North-South traffic.

The F5 Application Services Proxy (ASP) provides load balancing and telemetry for containerized applications, serving East-West traffic.

Let's Encrypt digital certificates are automatically installed on Virtual Servers on the Big-IP LTM.







Heketi provides a RESTful management interface which can be used to manage the life cycle of GlusterFS volumes. With Heketi, cloud services like OpenStack, Kubernetes, and OpenShift Origin can dynamically provision GlusterFS volumes with any of the supported durability types. Heketi will automatically determine the location for bricks across the cluster, making sure to place bricks and its replicas across different failure domains. Heketi also supports any number of GlusterFS clusters, allowing cloud services to provide network file storage without being limited to a single GlusterFS cluster.
