Understand Kubernetes

Kubernetes, an open-source platform for managing containerized workloads, has emerged as a popular technology for modern cloud infrastructure. Kubernetes has become the de facto standard for orchestrating containerized applications in the cloud. Embracing Kubernetes can unlock the full potential of cloud-native computing, enabling scalable, resilient, and efficient applications.

What is Kubernetes?

Kubernetes, often referred to as "K8s," is a container orchestration platform that automates the deployment, scaling, and management of applications running in containers. It was originally developed by Google and is now maintained by the Cloud Native Computing Foundation (CNCF).

Key features

  • Container orchestration: Kubernetes efficiently manages containers' lifecycle, ensuring that applications are deployed and run as intended across a cluster of machines.

  • Scalability: It allows applications to scale up or down automatically based on demand, improving resource utilization and reducing costs.

  • Self-healing: Kubernetes can automatically restart failed containers, replace them, and reschedule them to other nodes if necessary, ensuring high availability.

  • Load balancing: It automatically distributes incoming traffic across multiple instances of an application, enhancing performance and reliability.

  • Service discovery: Kubernetes assigns a unique IP address to each service and provides DNS naming, making it easy for applications to discover and communicate with each other.

  • Automated rollouts and rollbacks: It supports rolling updates for applications, enabling seamless updates and rollbacks with minimal downtime.

Why use Kubernetes in Rumble Cloud?

  • Flexibility: Kubernetes can run on various environments, including on-premises, public clouds like OpenStack, and hybrid clouds, providing flexibility in deployment options.

  • Efficiency: By leveraging containerization and Kubernetes, organizations can achieve better resource utilization, reducing the number of required servers and associated costs.

  • Speed: Kubernetes accelerates the development and deployment of applications, enabling faster time-to-market and continuous integration/continuous deployment (CI/CD) practices.

  • Open Source: As an open-source project, Kubernetes has a vibrant community and ecosystem, offering a wide range of tools, integrations, and support options.

Getting started with Kubernetes

  • Learn Kubernetes basics: Familiarize yourself with Kubernetes concepts, including pods, deployments, services, and namespaces.

  • Set up a Kubernetes cluster: In an OpenStack public cloud, you can use the Magnum service to easily create and manage Kubernetes clusters.

  • Deploy applications: Use Kubernetes manifests or Helm charts to deploy your containerized applications to the cluster.

  • Monitor and nanage: Utilize Kubernetes tools like kubectl and the dashboard to monitor the health of your applications and manage resources.
