Parte superiorConfigure and manage OpenShift clusters to maintain security and reliability across multiple applications and development teams.
Red Hat OpenShift Administration II: Configuring a Production 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.
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.
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, and OpenShift Container Platform.
This course is based on OpenShift Container Platform 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.

Contenido
Parte superiorDeclarative 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.
Pre-requisitos
