DO285 Containers, Kubernetes, and Red Hat OpenShift Administration I
Learn to build and manage Linux containers and configure and manage an OpenShift cluster
Containers, Kubernetes, and Red Hat OpenShift Administration I (DO285) helps you build core knowledge in building and managing Linux® containers and Red Hat® OpenShift® Container Platform. This hands-on, lab-based course shows you how to deploy sample applications to either a local container runtime or an OpenShift cluster, as well as how to configure and manage OpenShift clusters. If you’re a developer, administrator or site reliability engineer, you will benefit from learning these skills.
This course is based on Red Hat OpenShift Container Platform 4.2 and combines the content from Introduction to Containers, Kubernetes, and Red Hat OpenShift (DO180) and Red Hat OpenShift Administration I (DO280).

Impact on the organization
This course provides the gateway to organizational and digital transformation by providing an understanding of the potential of a container-based architecture. Containers and Red Hat OpenShift have quickly become the de facto solution for agile development and application deployment. This course is intended to develop 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.
Impact on the individual
After completing this course, you should be able to demonstrate the skills to create and manage local containers using Podman, establish a new OpenShift cluster, perform initial configuration of the cluster, and manage the cluster on a day-to-day basis. One major focus of the course is troubleshooting common problems that will be encountered beyond day one.
You should be able to demonstrate these skills:
