The Ultimate Openshift (2018) Bootcamp

Video description

This course will take you on a journey where you'll learn to Install and configure an OpenShift cluster using various options. You will learn about Platform as a Service and the advantages of building one with containers. Docker offers a way to run isolated processes and also allows you to package an application, along with its run time environment, using primitives such as dockerfiles. However, when it comes to running Docker in a production-like environment, with container workloads spanning across more than one node, you need a COE (Container Orchestration Engine). COEs offer clustering and convert your nodes into one super computer, make intelligent decisions as to where to schedule the containers, connect containers running on different nodes by setting up a multi-host network, and offer many other interesting features such as fault tolerance, zero downtime deployments, and more. OpenShift simplifies Kubernetes deployment by abstracting away the complexity and by providing a simple, unified interface. It also gives you a complete Platform as a Service offering by packaging Kubernetes, Container Registry, Container Runtime, and build and pipelines tools including Jenkins; it also creates best practices and integration out of the box. You can just point to your application code, and OpenShift builds and deploys it taking care of high availability, fault tolerance, scalability, self-healing, and reliability.

What You Will Learn

  • Understand Platform as a Service and the advantages of building one with containers
  • Install and configure an OpenShift Cluster using various options
  • Deploy applications with High Availability, Fault Tolerance, and Self-Healing built in
  • Set up service discovery and load balancing with OpenShift Services and Router, and understand service networking
  • Manage different types of workload with Deployments, Stateful sets, Crons, and Jobs
  • Understand how persistent storage works with PVs, PVCs, Storage classes, and dynamic provisioners
  • Set up Auto Scaling with the Horizontal Pod Autoscaler


This course is designed for developers who would like to deploy their applications with containers and are keen to understand how to leverage OpenShift features; operations or DevOps people who would like to build a PaaS or Container as a Service Offering and operate it; anyone who would like to understand OpenShift from the ground up; anyone who wants to run containers in production or production-like environments; and those who want to sit OpenShift certifications by RedHat.
