Figure 1. Red Hat OpenShift architecture



 Bastion hosts 

The Management host is a Red Hat® Enterprise Linux® 8.0 virtual machine (VM). This VM hosts services to install and configure the Red Hat® OpenShift® instance and provides utilities to manage the Red Hat OpenShift environment. This host is normally deployed in the VXLAN Subnet.





 Bootstrap hosts 

The bootstrap node is a Red Hat Enterprise Linux CoreOS (RHCOS), a new container-oriented operating system designed for running containers. The node is a temporary node that is used to start the installation.





 Control Plane hosts 

The control plane hosts are Red Hat Enterprise Linux CoreOS (RHCOS), a new container-oriented operating system designed for running containers. The control plane nodes are known as the control plane, where Kubernetes services such as API server, etcd, and controller manager are defined. An NSX® load balancer is configured to spread load across these VMs for ports 6443 and 22623, exposing the api and api-int functions.





 Worker hosts 

The worker hosts are Red Hat Enterprise Linux CoreOS (RHCOS), a new container-oriented operating system designed for running containers. The worker nodes are known as the data-plane, where the actual Kubernetes workloads are deployed. An NSX load balancer is configured to spread load across these VMs for ports 80 and 443, exposing the wildcard DNS and *.apps.

Setting up a Red Hat OpenShift for HPC cluster 

While IBM values the use of inclusive language, terms that are outside of IBM's direct influence are sometimes required for the sake of maintaining user understanding. As other industry leaders join IBM in embracing the use of inclusive language, IBM will continue to update the documentation to reflect those changes.



 Objective 



* Deploy a Red Hat® OpenShift® for HPC cluster with your choice of configuration properties







 Architecture overview and NFS file system setup 

The Red Hat OpenShift for HPC cluster consists of a login (bastion) node, a storage node where the block storage volume is attached, one or more instances of your Red Hat OpenShift master, and a number of worker nodes.



* The login node serves as a jump host and it is the only node that has a public IP address. The NFS node has only a private IP address and the only way to reach it is through the login node.
* By default, every cluster in Red Hat OpenShift on IBM Cloud® is set up with multiple Red Hat OpenShift master instances to ensure the availability and accessibility of your cluster resources, even if one or more of these masters become unavailable. Worker nodes are created across multiple availability zones in a region.
* Every cluster in Red Hat OpenShift on IBM Cloud is controlled by a dedicated Red Hat OpenShift master that is managed by IBM in an IBM-owned IBM Cloud infrastructure account. The Red Hat OpenShift master, including all of the master components, compute, networking, and storage resources, is continuously monitored by IBM Site Reliability Engineers (SREs). Since [Red Hat OpenShift on IBM Cloud](https://www.ibm.com/cloud/openshift) is a managed service, you cannot SSH directly into the master and worker nodes.
* The storage node is configured as an NFS server and the block storage is mounted to /data, which is exported to share with Red Hat OpenShift cluster worker nodes. If you want to use the NFS storage inside the pods, then you need to create persistent volumes and persistent volume claims and attach them into the pods.

 How does Red Hat OpenShift on IBM Cloud work? 

With Red Hat OpenShift on IBM Cloud, you can create your own Red Hat OpenShift cluster to deploy and manage containerized apps on IBM Cloud. Your containerized apps are hosted on IBM Cloud infrastructure compute hosts that are called worker nodes. You can choose to provision your compute hosts as [virtual machines](https://cloud.ibm.com/docs/openshift?topic=openshift-planning_worker_nodesvm) with shared or dedicated resources, or as [bare metal machines](https://cloud.ibm.com/docs/openshift?topic=openshift-planning_worker_nodesbm) that can be optimized for GPU and software-defined storage (SDS) usage. Your worker nodes are controlled by a highly available Red Hat OpenShift master that is configured, monitored, and managed by IBM. You can use the IBM Cloud Kubernetes Service API or CLI to work with your cluster infrastructure resources and the Kubernetes API or CLI to manage your deployments and services.

For more information about how your cluster resources are set up, see the [Service architecture](https://cloud.ibm.com/docs/containers?topic=containers-service-arch).
