Upon course completion, participants will possess the following competencies

• Demonstrated mastery of Kubernetes terminology
• Comprehensive understanding of Kubernetes cluster architecture
• Proficiency in executing practical directives for navigating the Kubernetes Command-Line Interface (CLI)
• Ability to proficiently prepare and deploy applications
• Competence in ensuring optimal application availability
• Skill in configuring zero-downtime upgrades
• Capacity to scale applications to requisite instance numbers
• Familiarity with delineated patterns governing the deployment of multiple containers within a pod
• Aptitude for strategizing recurring operations within the Kubernetes cluster
• Proficiency in debugging applications within the Kubernetes environment
• Ability to expose applications beyond the Kubernetes cluster
• Ability to leverage Helm charts for streamlined package management on Kubernetes

The training is intended for programmers, system engineers, and architects who want to learn how to properly deploy and manage applications on Kubernetes.

Basic command-line navigation skills are required. In case you bring your own laptop, please ensure that ssh client is installed.

During the training, we will be creating/editing files on the server. Editors such as 'nano' and 'vim' will be available for editing purposes. Additionally, participants will have the option to mount a directory with tasks locally via ssh (e.g., VSCode offers suitable extensions for this purpose) and use their favorite editor from their local machine.

The training is conducted in the form of alternating mini-lectures followed by practical exercises. It combines expert theoretical knowledge with practical examples of its application in the work environment.
