What is k8s?

Kubernetes is a container orchestration platform designed to streamline the management, deployment, and scaling of containerized applications. It abstracts the complexities associated with these tasks, facilitating seamless operations across diverse environments.

Key features of Kubernetes include automated rollout and rollback procedures, efficient scaling capabilities, and robust fault recovery mechanisms. These characteristics ensure high availability and resilience for applications, allowing for continuous operation and dynamic adjustments.

In subsequent lectures, we will explore additional features and functionalities offered by Kubernetes in greater detail.

Before Kubernetes, deploying, scaling, and managing applications involved manual processes and often required significant expertise and effort.

• Deployment typically required configuring servers, setting up networking, and managing dependencies manually, which could be time-consuming and error-prone.
• Scaling applications to handle changes in demand often involved manual intervention or custom scripting, which was complex and not easily scalable.
• Moreover, managing applications across different environments required separate tooling and workflows, leading to inconsistencies and additional overhead.

Overall, without Kubernetes, the process was labor-intensive, lacked automation, and was less efficient in terms of resource utilization and management.

Understanding the Relationship with Docker

Kubernetes (k8s) collaborates seamlessly with container tools like Docker. While Docker simplifies the creation of portable and isolated Containers, k8s focuses on streamlining the deployment, scaling, and management of containerized applications. In essence, k8s abstracts the complexities of underlying infrastructure, providing a unified platform for efficient operations.
