DO380: Red Hat OpenShift Administration III: Scaling Kubernetes Deployments in the Enterprise

This course supports IT operations teams that are in the prepare and expand stages of their Container Adoption Journey. This course expands upon the skills required to plan, implement, and manage OpenShift® clusters in the enterprise. You will learn how to support a growing number of stakeholders, applications, and users to achieve large-scale deployments.

Version:
This course is based on Red Hat® OpenShift Container Platform 4.5.

Course summary

• Manager and trigger application build
• Customize an existing source-to-image base imag
• Create an OpenShift template
• Create health checks to monitor and improve application reliability
• Create and deploy a Jenkins pipeline for continuous integration and continuous deployment
• Create and deploy cloud-native application for OpenShift

Audience

• Cluster engineers (systems administrators, cloud administrators, or cloud engineers) focused on planning, designing, and implementing production-grade OpenShift clusters. Cluster engineers require automation skills to scale their manpower to provision and manage an increasing population of clusters, applications, and users, at the same time ensuring these clusters remain in compliance with corporate standards.
• Site reliability engineers (SREs) focused on keeping OpenShift clusters and applications running without disruption. SREs are interested in troubleshooting infrastructure and application issues with OpenShift clusters and require automation skills to reduce the time to identify, diagnose, and remediate issues.

Prerequisites

Red Hat recommends these prerequisites:

• Complete the DO180: Red Hat OpenShift 1 - Containers and Kubernetes, or have equivalent knowledge
• Being a Red Hat Certified System Administrator or having earned a higher certification is helpful for navigation and usage of the command line, but is not required

Course outcome

As administrators and developers seek ways to improve application time to market for minimum viable products, containers and OpenShift have quickly become the de facto solution for agile development and application deployment. A container-based architecture, orchestrated with Kubernetes and OpenShift, improves application reliability and scalability while decreasing developer overhead and facilitating continuous deployment.

Building on the container foundations set in Introduction to Containers, Kubernetes, and Red Hat OpenShift (DO180), this offering represents the first developer-focused OpenShift course. This course provides the gateway to organizational and digital transformation by demonstrating the potential of DevOps using a container-based architecture.

As a result of completing this course, you should be able to understand the fundamental concepts behind containerizing, scaling, deploying, and managing applications in Red Hat OpenShift Container Platform. You will also acquire these skills:

• Design container images to containerize applicationsCu
• stomize application builds and implement post-commit build hook
• Create a multicontainer application template
• Implement health checks to improve system reliability.

Course outline

Deploy and manage applications on an OpenShift cluster
Deploy applications using various application packaging methods to an OpenShift cluster and manage their resources.

Design containerized applications for OpenShift
Select a containerization method for an application and create a container to run on an OpenShift cluster.

Publish enterprise container images
Create an enterprise registry and publish container images to it.

Manage building applications
Describe the OpenShift build process, in addition to triggering and managing builds.

Customize source-to-image builds
Customize an existing S2I base image and create a new one.

Create applications from OpenShift templates
Describe the elements of a template and create a multicontainer application template.

Manage application deployments
Monitor application health and implement various deployment methods for cloud-native applications.

Implement CI/CD pipelines in OpenShift
Create and deploy Jenkins pipelines to facilitate continuous integration and continuous deployment (CI/CD) with OpenShift.

Build cloud-native applications on OpenShift
Create and deploy cloud-native applications on OpenShift.

Certification

This course leads to the EX288: Red Hat Certified Specialist in OpenShift Application Development exam.

By passing this exam, you become a Red Hat Certified Specialist, which also counts toward becoming a Red Hat Certified Architect (RHCA®).
