CS120 Introduction to Red Hat OpenShift Service on AWS

Opis

Cel

Impact on the Organization

• Red Hat OpenShift Service on AWS (ROSA) is a turnkey application platform that provides a managed Red Hat OpenShift service that runs natively on Amazon Web Services (AWS) to enable organizations to increase operational efficiency, refocus on innovation, and quickly build, deploy, and scale applications
• Red Hat OpenShift is the hybrid cloud platform that brings operational consistency to on-premise and cloud environments. Organizations that use ROSA follow the same operational processes as on a self-managed Red Hat OpenShift Container Platform cluster in their on-premise data centers, and deploy the same applications on any OpenShift cluster, whether a managed cluster or a self-managed one

Impact on the Individual

• After completing CS120, students can create ROSA clusters. Most day-to-day application and cluster administration tasks are performed the same way across Red Hat OpenShift products, so IT professionals apply the same skills in managing Red Hat OpenShift clusters to both cloud and on-premise

Grupa docelowa

• Primary:
  • ROSA administrators
  • System administrators, platform engineers, cloud engineers, other infrastructure-related IT roles who are responsible for providing and supporting infrastructure for applications deployed on AWS.
• Secondary:
  • Enterprise architects
  • Application and development infrastructure professionals such as site reliability engineers and DevOps engineers.

Wymagania

• All students must be knowledgeable about Amazon Web Services (AWS), including operating and managing AWS compute, storage, and network resources
• For students who are new to Red Hat OpenShift, it is recommended that you learn the fundamental skills of managing Red Hat OpenShift clusters from the following courses:
  • Red Hat OpenShift I: Containers & Kubernetes (DO180)
  • Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster (DO280)
• Students with previous experience of managing Kubernetes clusters are advised to take DO180 and DO280 or at least to acquire foundational skills in operating Red Hat OpenShift clusters by using the following free resources from Red Hat:
  • Red Hat Developer Sandbox for OpenShift
  • OpenShift and Kubernetes learning from Red Hat Developer
  • Containers, Kubernetes and Red Hat OpenShift Technical Overview (DO080)

Konspekt

1. Create Public Red Hat OpenShift Service on AWS (ROSA) Clusters
   Create a Red Hat OpenShift Service on AWS (ROSA) cluster that is accessible through the internet
   • Introduction to ROSA
     Describe how ROSA clusters fit into the AWS infrastructure, the required tools to create and access ROSA clusters, and the typical deployment patterns for ROSA clusters: public, bring your own Amazon Virtual Private Cloud (VPC), and private link
   • Prerequisites for ROSA Cluster Creation
     Describe the required tools and services to create ROSA clusters. Prepare an AWS account and a management workstation to create a ROSA cluster, and verify that an AWS account meets all the prerequisites for creating a ROSA cluster
   • Creating a ROSA Cluster
     Create an internet-accessible ROSA cluster
   • Accessing a ROSA Cluster as an Administrator
     Create OpenShift cluster administrator credentials to access a managed cluster by using the OpenShift CLI, OpenShift Web Console, and Kubernetes CLI
   • Connecting a ROSA Cluster to Red Hat Services
     Connect a managed cluster to Red Hat Cloud Services
2. Configure Projects for Application Teams
   Configure projects for application teams to develop or deploy applications, and grant non-cluster administrators sufficient autonomy for their jobs and to prevent misusing a ROSA cluster and AWS services
   • Configuring Identity Providers for ROSA Clusters
     Configure an identity provider for developers to access a ROSA cluster and self-service projects to deploy unprivileged applications
   • OpenShift Multi-Tenancy with Projects
     Describe the OpenShift features that enable multi-tenancy
   • Configuring Project Self-Service
     Describe the OpenShift features that enable self-service for application teams
3. Declarative Project Management
   Automate project creation and ongoing maintenance by using OpenShift GitOps while preserving the autonomy of non-administrator users over those projects
   • GitOps for Kubernetes
     Define the fundamentals of GitOps and its use with Kubernetes clusters and applications. Describe the essential concepts of Argo CD that Red Hat OpenShift GitOps supports
   • Automating ROSA Cluster Management with OpenShift GitOps
     Describe the GitOps approach to automating OpenShift cluster management
   • Drift Remediation with OpenShift GitOps
     Describe ROSA resource reconciliation with OpenShift GitOps. Describe the OpenShift GitOps approach to remediating cluster state deviation
4. ROSA Cluster Upgrades
   Upgrade ROSA clusters with new OpenShift versions
   • OpenShift Updates and Application Availability
     Describe the OpenShift update process and how it affects application availability
   • Configuring Scheduled Cluster Upgrades
     Describe the process of scheduling a ROSA cluster upgrade and configuring automated y-stream upgrades
5. Delete ROSA Clusters
   Delete ROSA clusters and ensure that all of its related AWS resources are deleted
   • Deleting AWS Resources from Deleted ROSA Clusters
     Describe the process of deleting a ROSA cluster
   • Deleting AWS Resources from Deleted ROSA Clusters
     Describe scenarios that require manual deletion of AWS resources that are related to a ROSA cluster after the cluster was deleted

Uwagi

• classroom – 1 day
• VT – 2 days.

Recommended next course or exam

After completing CS120, students can proceed to additional operations and development training on Red Hat OpenShift, such as the following courses:

• Red Hat OpenShift Development II: Containerizing Applications (DO288)
• Red Hat OpenShift Administration III: Scaling Kubernetes Deployments in the Enterprise (DO380)
• Multicluster Management with Red Hat OpenShift Platform Plus (DO480)

Technology considerations

• Internet access is required to access AWS services by using the AWS console and the AWS CLI. It is also required to access the Red Hat Hybrid Cloud Console and associated Red Hat cloud services
• Students must possess an active AWS account with permission to activate services from the AWS Marketplace and an associated payment method for the AWS resources that ROSA clusters consume
• Students must possess an active Red Hat customer portal account or a free Red Hat Developer program membership
