Kubernetes Fundamentals and Cluster Operations

Anyone who is preparing to build and run Kubernetes clusters.

By the end of the course, you should be able to meet the following objectives:

• Build, test, and publish Docker container images
• Become familiar with YAML files that define Kubernetes objects
• Understand Kubernetes core user-facing concepts, including pods, services, and deployments
• Use kubectl, the Kubernetes CLI, and become familiar with its commands and options
• Understand the architecture of Kubernetes (Control plane and its components, worker nodes, and kubelet)
• Learn how to troubleshoot issues with deployments on Kubernetes
• Apply resource requests, limits, and probes to deployments
• Manage dynamic application configuration using ConfigMaps and Secrets
• Deploy other workloads, including DaemonSets, Jobs, and CronJobs
• Learn about user-facing security using SecurityContext, RBAC, and NetworkPolicies

• Linux concepts and command line proficiency.
• General networking proficiency.
