Docker and Kubernetes Training Overview
This Docker and Kubernetes Administration training teaches attendees how to use these technologies in enterprise and cloud environments. First, attendees learn the core features of Docker, including container creation, container management, and interacting with Docker Hub. Next, they learn the basic concepts and architecture of Kubernetes, such as its initial installation and setup, Kubernetes Pods, deployments and services, networking, and more. This Docker and Kubernetes course is hands-on, so attendees can practice what they learn using real-world examples.
