About this course
Picking up where OpenShift Administration I leaves off, this four-day course prepares a cluster for real production use. You will manage resources declaratively, deploy packaged applications with templates, Kustomize and Helm, set up authentication and authorisation, secure traffic with network policies, expose non-HTTP services, enable developer self-service and manage operator and cluster updates, preparing for Red Hat Certified OpenShift Administrator.
What you'll learn
- 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.
Curriculum
- Deploy and update applications from resource manifests that are parameterized for different target environments.
- Deploy and update applications from resource manifests that are packaged for sharing and distribution.
- Configure authentication with the HTPasswd identity provider and assign roles to users and groups.
- Protect network traffic between applications inside and outside the cluster.
- Expose applications to external access without using an Ingress controller.
- 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.
- Install and update Operators that are managed by the Operator Lifecycle Manager and by the Cluster Version Operator.
- Run applications that require elevated or special privileges from the host Operating System or Kubernetes.
- Update an OpenShift cluster and minimize disruption to deployed applications.
Who it's for
OpenShift administrators who have completed DO180 or can already deploy and manage applications from the console and CLI.
Before you start
- Red Hat OpenShift Administration I: Operating a Production Cluster (DO180) , 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.
