Kubernetes Install, Configure & Manage (en)

Teaching methodology:

The course includes educational laboratories in which each student will be able to work in order to complete training exercises that will provide practical experience in using the instrument, for each of the topics covered during the course.

Prerequisites:

• Have taken the DSK101 and DSK102 courses or have equivalent knowledge
• Basic knowledge of Linux: It is helpful to be familiar with the Linux operating system and the command line, as many of the Kubernetes administration tasks require the use of Linux commands and tools.
• Understanding of containerization concepts: It is advisable to have a basic understanding of containerization concepts and to understand how containers are used to isolate and deploy applications.
• Familiarity with basic Kubernetes concepts: It is advisable to have a basic understanding of how Kubernetes works, such as the concepts of pod, service, deployment and namespace, and how resources are managed within a Kubernetes cluster.
• Networking knowledge: It is useful to have an understanding of networking concepts, such as IP addressing, ports, protocols and routing, as Kubernetes involves networking logic to enable communication between cluster components.
• Command line experience: It is important to be familiar with using the command line (bash) to interact with the operating system and administration tools, as shell commands will be used to manage the Kubernetes cluster.
• Basic knowledge of operating systems and system administration: It is advisable to have a general knowledge of operating systems and basic system administration operations, such as managing processes, services, and configuration files.

At the end of the course the participants will be able to:

Educational program

• Properly configure kubeconfig files to allow access and authentication to the cluster. 
• Inspect and verify the status of the cluster using control and monitoring tools. 
• Install and configure a CNI for networking and security management. 
• Expand the cluster by adding new nodes to scale resources and improve performance. 
• Check and monitor the status of the cluster to ensure its stability and proper functioning. 
• Configure and use the LoadBalancer to expose the services contained in the cluster.
