This training is a combination of the Docker and Kubernetes.
Participants will first gain a basic understanding of Linux containers and proceed with learning the most important features of Docker Community Edition (CE) as well as their installation, initial setup and daily administration.
The second part of the course introduces participants to the basic concepts and architecture of Kubernetes, its initial install, setup and access control, Kubernetes Pods and Workloads, Scheduling and node management, Accessing the applications, Persistent storage in Kubernetes and finally its Logging, Monitoring and Troubleshooting facilities.
This course doesn’t only prepare delegates for the daily administration of Docker & Kubernetessystems but also for the official Certified Kubernetes Administrator (CKA) exam of the Cloud Native Computing Foundation (CNCF).
Structure: 50% theory 50% hands on lab exercises
