DO285: Containers, Kubernetes, and Red Hat OpenShift Administration I

Introduction to building and managing docker containers for deployment on a Kubernetes cluster. Containers, Kubernetes, and Red Hat OpenShift Administration I (DO285) helps you build core knowledge and skills in managing containers through hands-on experience with Docker, Kubernetes, and the Red Hat® OpenShift® Container Platform.

This course is based on Red Hat OpenShift Container Platform 3.9 and Red Hat® Enterprise Linux® 7.5. DO285 combines the content from Introduction to Containers, Kubernetes, and Red Hat OpenShift (DO180) and Red Hat OpenShift Administration I (DO280).

Through an introduction to Docker, Kubernetes, and Red Hat OpenShift Platform, this course helps you understand one of the key tenets of the DevOps movement: continuous integration and continuous deployment. Containers have become a key technology for the configuration and deployment of applications and microservices. Kubernetes is a container orchestration platform that provides foundational services in Red Hat OpenShift Container Platform, which allows enterprises to manage container deployments and scale their applications using Kubernetes.

In addition to gaining an understanding of these tools, you will build core administration skills through the installation, configuration, and management of an OpenShift cluster.

  • Impact on the organization

    This course is intended to expose you to container and container orchestration technologies such as Docker, Kubernetes, and Red Hat OpenShift. You are taught how to containerize software applications and services. Containers are rapidly becoming a deployment technology of choice in organizations adopting DevOps principles and practices. Moving applications and services from traditional deployment platforms to container deployments make the applications deployable on a single clustered cloud architecture instead of many disparate sets of hardware configurations. Upon completion, you will have developed the skills needed to install, configure, and manage the Red Hat OpenShift Container Platform to deploy containerized applications that are highly available, resilient, and scalable. Red Hat OpenShift Container Platform enables rapid application development and deployment, as well as portability of an application across environments. The platform also offers simplified application scaling, administration, and maintenance of adapted or cloud-native applications.

    Red Hat has created this course in a way intended to benefit our customers, but each company and infrastructure is unique, and actual results or benefits may vary.

    Impact on the individual

    As a result of attending this course, you should be able to install, configure, and manage a Red Hat OpenShift Container Platform cluster and deploy applications on it.

    You should be able to demonstrate these skills:

    • Install OpenShift Container Platform to create a simple cluster.
    • Configure and manage OpenShift masters and nodes.
    • Secure OpenShift with a simple internal authentication mechanism.
    • Control access to resources on OpenShift.
    • Deploy applications on OpenShift using source-to-image (S2I).
    • Configure and manage OpenShift pods, services, routes, secrets, and other resources.
