Hands-on Kubernetes from ROI Training

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
• Save data in Kubernetes using Persistent Volumes, StatefulSets, ConfigMaps, and Secrets
• Manage Kubernetes security with Role-Based Access Control (RBAC)

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.
