Learn to build and manage container images, administrate an OpenShift cluster, and troubleshoot applications running on Kubernetes

Containers, Kubernetes, and Red Hat OpenShift Administration II (DO285) helps you gain core knowledge in building and in configuring and managing Red Hat® OpenShift® Container Platform. This immersive and intensive, hands-on course shows you how to deploy applications to a local container engines and OpenShift clusters, manage the cluster on a day-to-day basis, and troubleshoot the deployment of containerized applications.

This course is based on Red Hat OpenShift Container Platform 4.6 and combines the content from Red Hat OpenShift I: Containers & Kubernetes (DO180) and Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster (DO280).

Objetivos

  • 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.

Impact on the organization

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.

Red Hat has created this course in a way intended to benefit our customers, but each company and infrastructure is unique, and actual results or benefits may vary.
