DO286 Containers, Kubernetes, and Red Hat OpenShift Administration I with exam

Opis

Learn to build and manage Linux containers and configure and manage an OpenShift cluster

Containers, Kubernetes, and Red Hat OpenShift Administration I with exam (DO286) helps you build core knowledge in building and managing Linux® containers and Red Hat® OpenShift® Container Platform. This hands-on, lab-based course shows you how to deploy sample applications to either a local container runtime or an OpenShift cluster, as well as how to configure and manage OpenShift clusters. If you’re a developer, administrator or site reliability engineer, you will benefit from learning these skills.

This course is based on Red Hat OpenShift Container Platform 4.5 and combines the content from Introduction to Containers, Kubernetes, and Red Hat OpenShift (DO180) and Red Hat OpenShift Administration I (DO280). 

The EX280 Red Hat Certified Specialist in OpenShift Administration exam (V4.5) or EX280V45K Red Hat Certified Specialist in OpenShift Administration exam is included in this bundle.

Course content summary

• Manage containers and container images.
• Create custom container images.
• Describe the Red Hat OpenShift Container Platform cluster installation and update processes.
• Troubleshoot application deployment issues.
• Control access to projects using groups and role-based access control (RBAC).
• Configure service and container networking.
• Expose applications to clients external to the cluster using TLS encryption.
• Configure network isolation between services and applications using network policies.
• Configure application scheduling using labels and selectors.
• Limit compute resource usage of applications with resource limits and quotas.
• Install Kubernetes Operators with the web console.

Cel

This course provides novice administrators with the essential skills to configure and manage Red Hat OpenShift Container Platform clusters to support containerized applications that are highly available, resilient, and scalable. Red Hat OpenShift Container Platform is an enterprise, hardened distribution of Kubernetes that enables rapid application development and deployment, as well as portability of applications and operational processes across cloud providers and traditional data centers.

Impact on the individual
After completing this course, you should be able to demonstrate the skills necessary to execute and build local containers, establish the health of a new OpenShift cluster, grant users and developers access to the cluster, and manage the cluster on a day-to-day basis. One major focus of the course is troubleshooting common problems that will be encountered beyond day one as users and applications use cluster resources.

Grupa docelowa:

• System and software architects interested in understanding features and functionality of an OpenShift cluster
• System administrators who want to learn about the initial establishment of a cluster
• Cluster operators responsible for the ongoing maintenance of a cluster
• Site reliability engineers interested in the ongoing maintenance and troubleshooting of a cluster
