Course 960:
Hands-On Kubernetes

(3 days)

 

Course Description

Kubernetes is an open-source, cross-platform, container orchestration system. It is supported by all major public cloud providers, and can also be used on-premises. It is an industry-standard for deploying cloud-native applications that can be deployed anywhere. This course provides the knowledge necessary to use Docker and Kubernetes to deploy your microservice applications to any cloud.

Learning Objectives

  • Leverage Kubernetes for container orchestra and automated deployment
  • Build, run, and deploy container applications using Docker
  • Configure Kubernetes clusters in the cloud
  • Automate application management using the kubectl CLI and configuration
  • Deploy scalable, fault-tolerant applications using Kubernetes Deployments, Services, Jobs, CronJobs, and DaemonSets
  • Migrate to new versions of services safely with zero downtime
  • Save data in Kubernetes using Persistent Volumes, StatefulSets, ConfigMaps, and Secrets
  • Simplify Kubernetes deployments with Helm
  • Manage Kubernetes security with Role-Based Access Control (RBAC)
  • Enhance Kubernetes networking with network policies

Who Should Attend

Architects, engineers, and developers who want to learn to use Kubernetes to build cloud-native, microservice applications and automate their deployment using Kubernetes.

Hands-On Activities

This class includes hands-on labs. Most labs focus on Kubernetes concepts and will work on any Kubernetes cluster. The labs to provision and manage the cluster will be performed on Google Kubernetes Engine (GKE). Amazon Elastic Kubernetes Service (EKS) or Azure Kubernetes Service (AKS) will be demonstrated in the course.
