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.- Platform Administrators, System Administrators, Cloud Administrators, and other infrastructure-related IT roles who are responsible for managing and maintaining infrastructure for applications. - Enterprise Architects, Site Reliability Engineers, DevOps Engineers, and other application-related IT roles who are responsible for designing infrastructure for applications.- 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.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.5 days4057.004057.003230.004057.003363.003496.002841.004057.004057.004057.0013.00
