Docker And Kubernetes for Infrastructure Professionals

This is a lecture and hands-on course designed for infrastructure professionals and covers core Docker and Kubernetes technologies. including docker concepts, repository, networking, and storage.

Kubernetes cluster architecture, steps in how to build Kubernetes cluster, deploy and manage applications on Kubernetes, high availability, Kubernetes Storage, Rolling updates, Scaling, Monitoring, Advanced Networking and how to secure Kubernetes.

There are many hands-on practice, including deploying a multi-master multi-node bare metal fault tolerant Kubernetes cluster, managing users accounts, and namespace, practicing on volumes, and secrets, using prometheus/grafana tool to monitor workloads, hands-on practice in autoscaling.
