OVERVIEW

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, and authentication systems.

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

This course is based on Red Hat OpenShift 4.14.

Following course completion, hands-on lab access will remain available for up to
45 days for any live course that includes a virtual environment.

Note: This course is offered as a four day in classroom, a five day virtual
class, or self-paced. Durations may vary based on the delivery. For full course
details, scheduling, and pricing, select your location then “get started” on the
right hand menu.


COURSE CONTENT SUMMARY

 * Managing OpenShift clusters from the command-line interface and from the web
   console
 * Deploying applications on OpenShift from container images, templates, and
   Kubernetes manifests
 * Troubleshooting network connectivity between applications inside and outside
   an OpenShift cluster
 * Connecting Kubernetes workloads to storage for application data
 * Configuring Kubernetes workloads for high availability and reliability
 * Managing updates to container images, settings, and Kubernetes manifests of
   an application


TARGET AUDIENCE

 * Primary: Platform Engineers, System Administrators, Cloud Administrators, and
   other infrastructure-related IT roles who are responsible for tier-1 support
   of infrastructure for applications.who are interested in managing OpenShift
   clusters and containerized applications.
 * Secondary: Enterprise Architects, Site Reliability Engineers, DevOps
   Engineers, and other application-related IT roles who are responsible for
   designing infrastructure for applications.
 * Developers and Site Reliability Engineers that are new to container
   technology should enroll in Red Hat OpenShift Development I: Introduction to
   Containers with Podman (DO188).


RECOMMENDED TRAINING

 * Take our free assessment to gauge whether this offering is the best fit for
   your skills.
 * Prerequisite: Containers, Kubernetes and Red Hat OpenShift Technical Overview
   (DO080) or equivalent knowledge of Linux containers.
 * Prerequisite: Getting Started with Linux Fundamentals (RH104) or equivalent
   proficiency in using a command line interface, ideally operating a Bash
   shell, is required.


TECHNOLOGY CONSIDERATIONS

 * This course requires internet access to access the cloud-based classroom
   environment that provides an OpenShift cluster and a remote administrator’s
   workstation.

OUTLINE


INTRODUCTION TO KUBERNETES AND OPENSHIFT

Identify the main Kubernetes cluster services and OpenShift platform services,
and monitor them from the web console.


KUBERNETES AND OPENSHIFT COMMAND-LINE INTERFACES AND APIS

Access an OpenShift cluster from the command line, and query its Kubernetes API
resources to assess the health of a cluster.


RUN APPLICATIONS AS CONTAINERS AND PODS

Run and troubleshoot containerized applications as unmanaged Kubernetes pods.


DEPLOY MANAGED AND NETWORKED APPLICATIONS ON KUBERNETES

Deploy applications and expose them to network access from inside and outside a
Kubernetes cluster.


MANAGE STORAGE FOR APPLICATION CONFIGURATION AND DATA

Externalize application configurations in Kubernetes resources, and provision
storage volumes for persistent data files.


CONFIGURE APPLICATIONS FOR RELIABILITY

Configure applications to work with Kubernetes for high availability and
resilience.


MANAGE APPLICATION UPDATES

Manage reproducible application updates and rollbacks of code and
configurations.

OUTCOMES


IMPACT ON THE ORGANIZATION

 * This course is intended to develop the skills needed to manage Red Hat
   OpenShift clusters and support containerized applications that are highly
   available, resilient, and scalable. Red Hat OpenShift is an
   enterprise-hardened application platform based on Kubernetes that provides a
   common set of APIs and abstractions that enable application portability
   across cloud providers and traditional data centers. Red Hat OpenShift adds
   consistency and portability of operational processes across these
   environments and can also be deployed as a managed service. An external SRE
   team shares the responsibility of managing Red Hat OpenShift clusters with a
   customer’s IT operations team when using a managed OpenShift offering such as
   Red Hat OpenShift on AWS (ROSA) or Azure Red Hat OpenShift.


IMPACT ON THE INDIVIDUAL

 * As a result of attending this course, students will understand the
   architecture of Red Hat OpenShift clusters and of Kubernetes applications,
   and will be able to deploy, manage, and troubleshoot applications on
   OpenShift. Students will also be able to identify and escalate application
   and infrastructure issues to development teams, operation teams, and IT
   vendors.


RECOMMENDED NEXT COURSE OR EXAM

 * Red Hat OpenShift Administration II: Operating a Production Kubernetes
   Cluster (DO280)
 * Red Hat Certified OpenShift Administrator exam (EX280)
 * Introduction to Red Hat OpenShift Service on AWS (CS120)
 * Introduction to Microsoft Azure Red Hat OpenShift (DO121)
