Red Hat OpenShift Cluster Management

OverviewOutlinePre requisiteEX432

Address challenges with management, compliance, and productivity of a multicluster Kubernetes environment and its applications by using the capabilities of Red Hat Advanced Cluster Management for Kubernetes.

Course Description

Multicluster Management with Red Hat Advanced Cluster Management for Kubernetes (RHACM) teaches the required skills to manage a fleet of containerized applications and Kubernetes clusters, by automating compliance with security, governance, and other organization policies, and by implementing GitOps practices.

Course Content Summary

  • Describe and implement the RHACM architecture and its components, and follow recommended practices for its installation.
  • Import and manage a cluster by using the RHACM web console, configure user access to clusters, and troubleshoot common import issues.
  • Deploy and manage policies in a multicluster environment by using RHACM governance.
  • Monitor a fleet of managed clusters and troubleshoot performance and availability issues by using RHACM observability components.
  • Deploy and manage applications in a multicluster environment by using RHACM and GitOps.
  • Deploy and manage virtual machines in a multicluster environment by using RHACM and GitOps.

Target Audience 

  • IT Operations personnel who are responsible for managing the lifecycle and monitoring the usage of multiple clusters.
  • DevOps and Site Reliability Engineers who are responsible for monitoring the health of clusters and Kubernetes deployments and for maximizing their uptime. These individuals also automate the provisioning or deprovisioning of clusters and the workload placement based on capacity and policy.
  • Security Operations personnel who are responsible for ensuring that Kubernetes deployments comply with regulatory and organizational standards. These individuals create security policies across diverse environments and ensure enforcement.
