Containers, Kubernetes, and Red Hat OpenShift Administration II Training

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 4.10 and combines the content from Red Hat OpenShift I: Containers & Kubernetes (DO180) and Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster (DO280).

It is very difficult to become a good Kubernetes Administrator without any Linux knowledge, but if you know the basics of Linux, it will be easier for you to learn Kubernetes. You only need a score of 66% or higher to pass the Certified Kubernetes Administrator (CKA) Exam; This score is not difficult if you've practiced and prepared by attending one of our Kubernetes trainings.

Kubernetes is an open-source framework for managing containerized workloads and services that allows for declarative configuration as well as automation. It has a large and rapidly growing ecosystem and Kubernetes services, support, and tools are widely available. Kubernetes project became open-source in 2014 thanks to Google. Kubernetes with Docker has consolidated practices from the community and Google's knowledge of operating production loads at scale with the best ideas.

Docker is a container management system similar to Kubernetes. Docker is fundamentally incorporated into the Docker community and focuses on Docker file clustering. Docker and Kubernetes differ in that, Docker is intended to operate on a single node, while Kubernetes is intended to run in a cluster. Another distinction between Kubernetes and Docker is that Docker can be used without Kubernetes, while Kubernetes requires the use of a container runtime in order to orchestrate.

Kubernetes is a Docker container orchestration framework that is open source. It manages workload scheduling on compute cluster nodes and carries out these tasks to maintain that their state corresponds to the clients' stated intentions. Kubernetes Docker is very popular in virtualization and is used by many companies such as Google, Slack, Robinhood, Shopify, Udemy, Delivery Hero, and StackShare.
