Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster

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. 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.

Take our free assessment to gauge whether this offering is the best fit for your skills. Prerequisite: Red Hat OpenShift Administration I: Operating a Production Cluster (DO180v4.14), or equivalent skills deploying and managing Kubernetes applications using the OpenShift web console and command-line interfaces. Significant experience with Linux System Administration is not needed for this course. Basic skills operating a Bash shell, manipulating files and processes, and verifying system confirmations such as network addresses are necessary and sufficient. Students are encouraged to take Getting Started with Linux Fundamentals (RH104) before enrolling in DO280 Technology considerations
• This course requires internet access to access the cloud-based classroom environment that provides an OpenShift cluster and a remote administrator’s workstation.

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.
