Kubernetes getting started

Course description

This course introduces participants to container orchestration with Kubernetes. Attendees will master the foundational concepts of Kubernetes in development and production through a combination of presentations, demos, and hands-on labs, including building and deploying Kubernetes applications, cluster monitoring and debugging.

This course also covers system components, core resources, and the requirements for minimum viable cluster security.

This training provides a solid foundation for passing the CKAD certification.

Goals

  • Understand the interest and characteristics of Kubernetes and microservices
  • Know how to deploy “ Cloud-Native ” applications on a large scale on a cluster or in the cloud
  • Mastering kubeadm, the Kubernetes installation tool
  • Understand how to deploy Kubernetes in production
  • Enable automatic application scaling
  • Implement high availability and self-healing of software services
  • Optimize the storage of large masses of data with volumes
  • Develop advanced infrastructure and application monitoring
  • Automate the updating of the software versions of its applications

Targeted audience

This course is designed for those who are new to Kubernetes and containers, as well as those who have had exposure but would like to gain a deeper understanding. No prior knowledge of Kubernetes is required. This course is suitable for developers, operations, architects and anyone seeking to gain a strong foundation in modern, Cloud Native software delivery.
