Overview

The "Introduction to Containers, Kubernetes, and OpenShift" course is designed to offer a comprehensive understanding of container orchestration, leveraging Kubernetes and OpenShift platforms. This course begins with foundational concepts of container technology, including an overview of daemonless containers and essential tools like Podman and Buildah, which are critical for managing container lifecycles and configurations. Participants will gain practical skills in creating and managing container images using industry-standard practices, which are crucial for streamlining application deployment in modern IT environments. The course also covers essential networking aspects, emphasizing container network interfaces and service discovery, thereby equipping attendees with the skills to architect resilient and scalable applications. The course progresses to advanced Kubernetes core concepts, such as understanding its architecture, mastering cluster communication, and working with Kubernetes objects and properties. It emphasizes the importance of YAML configuration files for defining and managing complex Kubernetes environments, offering a blend of theoretical knowledge and hands-on labs for practical understanding. Attendees will delve into managing application lifecycles, exploring the intricacies of pod and container lifecycle management, and the use of Init Containers and ReplicaSets for ensuring high availability and seamless application updates. These skills are essential for professionals aiming to excel in cloud-native application management and deployment. Finally, the course provides an in-depth exploration of OpenShift, comparing its features with Kubernetes and highlighting its enterprise advantages, such as enhanced security, integrated developer tools, and seamless CI/CD pipelines. Participants will learn about OpenShift's architecture and its additional capabilities, like managing custom resources with the Operator Lifecycle Manager, offering a robust framework for deploying cloud-native applications in an enterprise context. The course's practical labs enable learners to apply concepts through real-world scenarios, preparing them to handle complex projects and effectively leverage the power of OpenShift for advanced cloud solutions.
