Red Hat OpenShift Administration II: Configuring a Production Cluster

Configure, manage, and troubleshoot OpenShift clusters and containerized applications.

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. DO280 focuses on configuring multi-tenancy and security features of OpenShift. DO280 also teaches how to manage OpenShift add-ons based on operators.

Nastavni plan

Declarative Resource Management
  • Deploy and update applications from resource manifests that are parameterized for different target environments.
Deploy Packaged Applications
  • Deploy and update applications from resource manifests that are packaged for sharing and distribution.
Authentication and Authorization
  • Configure authentication with the HTPasswd identity provider and assign roles to users and groups.
Network Security
  • Protect network traffic between applications inside and outside the cluster.
Expose non-HTTP/SNI Applications
  • Expose applications to external access without using an Ingress controller.
Enable Developer Self-Service
  • Configure clusters for safe self-service by developers from multiple teams and disallow self-service if projects have to be provisioned by the operations staff.
Manage Kubernetes Operators
  • Install and update Operators that are managed by the Operator Lifecycle Manager and by the Cluster Version Operator.
Application Security
  • Run applications that require elevated or special privileges from the host Operating System or Kubernetes.
OpenShift Updates
  • Update an OpenShift cluster and minimize disruption to deployed applications.
