Efficient Kubernetes Namespace Segmentation

Join us as we delve into the concept of Kubernetes namespaces and how to simplify cluster management by adopting a tenant-based approach. In this video, we'll explore the pragmatic partitioning of namespaces into four essential categories that cater to various operational needs within your Kubernetes environment. Discover the roles of the 'kube-system', 'infra', 'domain', and 'CI/CD' namespaces, and learn why such a structure promotes both security and efficiency.

Key Highlights:

- The Role of Namespaces: Understand what namespaces are and how they function as tenants within your Kubernetes cluster, grouping users by permission structures.
- The Four Namespace Model: Learn about the four key namespaces that most organizations need, including their distinct roles and how they foster a secure and manageable cluster environment.
- Segregation for Security and Ease of Management: We discuss the advantages of segregating namespaces for 'infra' and 'domain', ensuring secure management of resources and secrets, while simplifying permissions and access.
- Empowering Developers: Find out how a well-organized namespace strategy can empower developers to manage their applications more effectively, providing them the confidence and clarity to maintain production environments.
- RBAC (Role-Based Access Control): Get insights on implementing RBAC to control visibility and access within your cluster, ensuring developers can focus without the clutter of unrelated resources.

Whether you're managing a large-scale infrastructure or a small development team, this video will provide you with a clear, streamlined approach to namespace management in Kubernetes. This is not about overhauling your current system but enhancing the way you view and utilize namespaces for better control and clarity.

Great video! This ties really well in with fluxcd concept of multitenancy and add a seperation with git sources as well allowing developers to have a cicd setup with in their own repo and deploying from there as well in to their own namespaces that is allocated for them. Regarding resources, wouldn't it be better give every developer team their own namespace and then build resource quotas on that namespace. That will give you fair use in the cluster and it builds a great dashboard for who is using how much.

It is challenging, I've frequently asked architects to think about the names pacing issue in terms not just about the business domain or business divisions but also in the way they use modules, packages, namespaces and libraries within the code that their developers develop. And consider that the kube NS, is the apex domain fir the app that they are designing for that part of the business. My main complaint is that businesses like to keep IT work segmented away from the people doing the engineering of applications that make the business function. Anyway, good video , it's an enjoyable watch and it does highlight a core issue with the meta environment between applications and infrastructure
