    DO280 Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster



    Configure and manage OpenShift clusters to maintain security and reliability across multiple applications and development teams. Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster (DO280) prepares OpenShift Cluster Administrators to perform daily administration tasks on clusters that host applications provided by internal teams and external vendors, enable self-service for cluster users with different roles, and deploy applications that require special permissions such as such as CI/CD tooling, performance monitoring, and security scanners. This course focuses on configuring multi-tenancy and security features of OpenShift as well as managing OpenShift add-ons based on operators. The skills you learn in this course can be applied using all versions of OpenShift, including Red Hat OpenShift on AWS (ROSA), Azure Red Hat OpenShift (ARO), and OpenShift Container Platform. This course is based on OpenShift Container Platform 4.12.

    5-10 Course Topics

    • Deploying packaged applications using manifests, templates, kustomize, and helm.
    • Configuring authentication and authorization for users and applications.
    • Protecting network traffic with network policies and exposing applications with proper network access.
    • Deploying and managing applications using resources manifests.
    • Enabling developer self-service of application projects.
    • Managing OpenShift cluster updates and Kubernetes operator updates.


    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 (ARO).


    Impact on the individual

    • As a result of attending this course, students will be able to perform the set of tasks that OpenShift cluster administrators are expected to perform in their daily jobs for on-premises, cloud-based, and vendor-managed clusters, including enabling add-on operators. Students will also be able manage multi-tenant permissions for different roles and configure applications that require privileged access to cluster and host resources.

    Grupa docelowa

    This course is designed for system administrators, system architects, and developers who want to install and configure Red Hat OpenShift Container Platform.

    • System Administrators and Platform Operators interested in the ongoing management of OpenShift clusters, applications, users, and add-ons.

    Outline for this course

    1. Declarative Resource Management
      • Deploy and update applications from resource manifests that are parameterized for different target environments.
    2. Deploy Packaged Applications
      • Deploy and update applications from resource manifests that are packaged for sharing and distribution.
    3. Authentication and Authorization
      • Configure authentication with the HTPasswd identity provider and assign roles to users and groups.

    7. Manage Kubernetes Operators
      • Install and update Operators that are managed by the Operator Lifecycle Manager and by the Cluster Version Operator.
    8. Application Security
      • Run applications that require elevated or special privileges from the host Operating System or Kubernetes.
    9. OpenShift Updates
      • Update an OpenShift cluster and minimize disruption to deployed applications.
