I.       Overview:

Kubernetes (K8s) is an open source platform for managing applications that are hosted on multiple servers, used to automate system deployment, and manage containers. Kubernetes is developed and designed by engineers at Google.

The course focuses on hands-on installation, operation, and troubleshooting related to Kubernetes (K8s) systems. The course is based on the Certified Kubernetes Administrator (CKA) certification from the Cloud Native Computing Foundation (CNCF).

II.    Duration:

05 days (40 hours)

III. Objectives

This course teaches you how to:

-       Install new system standalone/cluster Kubernetes.

-       Network infrastructure management in the Kubernetes system.

-       Managing the storage system of Kubernetes.

-       Manage Kubernetes cluster on bare metal server/cloud system.

-       Fix problems related to applications, networks, clusters of Kubernetes.

-       Improve the ability to operate the container orchestration system when using Kubernetes.

-       Take the CKA certification exam.

IV. Intended Audience

This course is intended for:

-       System administrators in enterprises have been using Linux Containers.

-       Students want to improve their management knowledge in the system using Containers.

-       Students already have knowledge about Containers and want to become a DevOps expert in the future.

V.    Prerequisites

We recommend that attendees of this course have the following prerequisites:

-       Have basic knowledge about docker/container

-       Have knowledge and experience work with linux system
