Overview

Accelerated hands-on training to boost developer productivity powered by Red Hat OpenShift

Containers, Kubernetes, and Red Hat OpenShift Development I (DO295) teaches you how to design, build, and deploy containerized software applications to an OpenShift® cluster. Whether you are tasked with writing container-native applications or migrating existing brownfield applications, this course provides hands-on training to boost developer productivity powered by Red Hat OpenShift.

Target Audience

  • Developers who wish to containerize software applications.
  • Administrators who are new to container technology and container orchestration.
  • Architects who are considering using container technologies in software architectures.
  • Site reliability engineers who are considering using Kubernetes and OpenShift.

Prerequisites

  • Be able to use a Linux terminal session, issue operating system commands, and be familiar with shell scripting
  • Have experience with web application architectures and their corresponding technologies
  • Being a Red Hat Certified System Architect is recommended, but not required

Learning Outcomes

  • Explore container and OpenShift architecture
  • Create containerized services
  • Manage containers and container images
  • Build custom container images
  • Manage and trigger application builds
  • Customize an existing source-to-image base image
  • Develop an OpenShift template
  • Generate health checks to monitor and improve application reliability

Impact on the organization

Containers are a key technology for the configuration and deployment of applications and microservices, and containers and OpenShift have quickly become the de facto solution for agile development and application deployment. Administrators and developers are seeking ways to improve application time-to-market for minimum viable products. This course provides the gateway to organizational and digital transformation by providing an understanding of the potential of DevOps using a container-based architecture. Orchestrated with Kubernetes and OpenShift, a container-based architecture improves application reliability and scalability, while decreasing developer overhead and facilitating continuous deployment.

Impact on the individual

As a result of attending this course, you will understand the fundamental concepts behind containerizing, scaling, deploying, and managing applications on Red Hat OpenShift Container Platform, which is a containerized application platform that allows enterprises to manage container deployments and scale their applications using Kubernetes.

You should be able to demonstrate these skills:

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