DO180

Deploy, manage, and troubleshoot containerized applications running as Kubernetes workloads in OpenShift clusters.

Course Description

Red Hat OpenShift Administration I: Operating a Production Cluster (DO180) prepares OpenShift cluster administrators to manage Kubernetes workloads and to collaborate with developers, DevOps engineers, system administrators, and SREs to ensure the availability of application workloads. This course focuses on managing typical end-user applications that are often accessible from a web or mobile UI and that represent most cloud-native and containerized workloads. Managing applications also includes deploying and updating their dependencies, such as databases, messaging systems, and authentication systems.

The skills that you learn in this course apply to all versions of OpenShift, including OpenShift Container Platform, Red Hat OpenShift on AWS (ROSA), and Azure Red Hat OpenShift.

This course is based on Red Hat^® OpenShift^® Container Platform 4.22.

Business Outcome

Organizations frequently struggle with operational complexity and a lack of consistency when managing containerized applications across diverse hybrid cloud environments. This course addresses these challenges by equipping IT teams to use the unified operational processes and Kubernetes abstractions of Red Hat® OpenShift® to ensure application portability, maximize service reliability, and confidently support highly available workloads across traditional data centers and managed cloud services.

Student Outcome

As a result of attending this course, students are expected to understand the architecture of Red Hat OpenShift clusters and can deploy, manage, and troubleshoot containerized applications. Students can also collaborate with cross-functional teams to ensure workload availability, and seamlessly identify, resolve, or escalate infrastructure issues.

Specifically, students can demonstrate the following skills:

• Manage OpenShift clusters by using both the command-line interface (CLI) and the unified web console.
• Deploy applications on OpenShift from container images, templates, and Kubernetes manifests.
• Troubleshoot network connectivity between applications inside and outside an OpenShift cluster. 
• Connect Kubernetes workloads to persistent storage for application configuration and data.
• Configure Kubernetes workloads for high availability, reliability, and automated scaling. 
• Manage safe and reproducible updates to container images, settings, and Kubernetes manifests.

Target Audience

• System Administrators who are interested in the ongoing management of OpenShift clusters and containerized applications.
• Site Reliability Engineers who are interested in the ongoing maintenance and troubleshooting of containerized applications on Kubernetes.
• System and Software Architects who are interested in understanding the features and functions of an OpenShift cluster.

Recommended Preparation

• Containers, Kubernetes and Red Hat OpenShift Technical Overview (DO080) or equivalent knowledge of Linux containers.

• Basic skills in operating a Bash shell, manipulating files and processes, and verifying system confirmations such as network addresses, are necessary and sufficient. Students are encouraged to take Getting Started with Linux Fundamentals (RH104) before enrolling in DO180.
