Managing from 1 to 1 million Kubernetes Clusters - Bastian Hofmann - PHP UK 2022

Learn how to manage Kubernetes clusters at scale, from 1 to 1 million, with Rancher and K3S, and explore the flexibility of running Kubernetes on various infrastructures and providers, from on-premises to cloud and edge devices.

Key takeaways
  • Kubernetes can be managed from a central plane of glass, with tools like Rancher, to control all clusters and infrastructures.
  • Running Kubernetes on-premises can be challenging, but tools like K3S make it easier to set up and manage.
  • Kubernetes can be run on various infrastructure providers, including cloud providers, edge devices, and on-premises data centers.
  • The Rancher tool allows for easy setup and management of Kubernetes clusters, with a UI for configuring clusters and deploying applications.
  • The Kubernetes API can be extended to support additional features and functionalities.
  • The Rancher tool integrates with Helm, a package manager for Kubernetes, to make it easier to deploy and manage applications.
  • Kubernetes provides a highly scalable and flexible framework for containerized applications.
  • Kubernetes can be used to manage stateful sets, and default values can be set for specific infrastructure providers.
  • Kubernetes provides built-in abstractions and APIs for managing various types of resources, including pods, services, and deployments.
  • The Rancher tool provides a single pane of glass for managing multiple Kubernetes clusters, with features such as monitoring and logging.
  • Kubernetes provides a high level of security and scalability, with features such as network policies, role-based access control, and self-healing clusters.
