Kubernetes Developer CKAD
The Kubernetes Developers CKAD Course is designed to teach you how to use Kubernetes to deploy, scale, and manage containerized applications. Course objectives include understanding Kubernetes architecture and components, interacting with a Kubernetes cluster using kubectl, using YAML manifests to define and deploy applications, implementing network services to expose applications, managing storage for application data, implementing security and access best practices, integrating Kubernetes with Continuous Integration and Continuous Deployment (CI/CD) processes, and finally preparing for the exam of Kubernetes Application Developer CKAD Certification .
Course Objectives
The main objectives of the Kubernetes Developer CKAD Course :
- Gain a deep understanding of Kubernetes architecture and its core components.
- Learn to use kubectl commands proficiently for cluster interaction and management tasks.
- Master the creation and deployment of applications using YAML manifests in Kubernetes.
- Implement and manage network services to expose applications within Kubernetes clusters.
- Develop skills in managing storage resources effectively for application data within Kubernetes environments.
- Implement security measures and best practices to secure Kubernetes clusters and applications.
- Integrate Kubernetes deployments seamlessly into CI/CD pipelines for automated application delivery.
- Prepare thoroughly for the Kubernetes Application Developer CKAD Certification exam through hands-on labs and practice scenarios.
