Implement Red Hat OCP in ThinkAgile CP

Lenovo has added a template to the ThinkAgile CP marketplace that will enable infrastructure admin users to create Red Hat OpenShift Container Platform (OCP) clusters on ThinkAgile CP.

Red Hat OCP is a cluster-based platform (based on Kubernetes) that can used to develop and run containerized applications. At a minimum, Red Hat clusters consist of the following machines:

• Three control plane nodes, which are also called master nodes. The control plane nodes contain the services that are used to manage the cluster.

• Two compute nodes, which are also called worker nodes. The actual workloads are run on the compute nodes.

• One temporary bootstrap node that is used to deploy the OCP cluster on the control plane nodes. After the cluster is deployed, the bootstrap node can be removed.

For more information about Red Hat OCP, see the following website:

https://docs.openshift.com/container-platform/4.5/welcome/index.html

Complete the following steps to set up an OCP cluster:

• Create VMs for the cluster components
  Install the Red Hat OCP Bastion Template and use it to set up the VMs for the devices in the cluster.
• Run Ansible playbooks to configure the Bastion node
  Run Ansible playbooks to configure the Bastion node.
• Set up the bootstrap node
  The bootstrap node is a temporary node that is used to deploy the OCP cluster on the control plane nodes. After the cluster is deployed, the bootstrap node can be removed.
• Set up the control plane nodes
  The control plane nodes, which are also known as master nodes, contain the services that are used to manage the cluster.
• Set up the compute nodes
  The compute nodes, which are also known as worker nodes, run the workloads.
• Complete the OCP installation process
  After completing the OCP installation process, you can establish access the web console.
