An overview of deploying Kubernetes on Premise

Bobby Martin | October 15, 2019 | 0 | Computers & Electronics

Kubernetes is an open-source platform that is portable and extensible, designed to managed cointainerized applications. There are two ways to deploy the container platform, on-premises and public cloud infrastructure. Deploying Kubernetes on premise is often a primary choice but it doesn’t apply in all situations.

But first, a short overview of Kubernetes. 

In this article, you will learn about the origins of the popular open-source project and why it matters. 

Kubernetes can be likened to a cluster or datacenter OS that manages an entire cluster’s resources. It doesn’t matter whether the nodes are in the cloud or on-premise, Kubernetes takes care of the underlying details so developers don’t have to worry about them. 

That is, they only need to develop an app for Kubernetes and not have to think about whether the right amount of resources are located or where the app will run.  

What are the differences between deploying Kubernetes on Premise and in the cloud? 

On-premises environments need to be repurposed so that they will integrate well with Kubernetes. In some cases, you not only need to create clusters on top of virtual machines but create a new infrastructure as well.

This also means you’ll be able to plan for the right networking and storage equipment to ensure automated networking and storage components. 

Implementation in public cloud environments is less complicated as deployment tools of Kubernetes can natively integrate with them. This makes configuration of networking and storage services easy for day-to-day operations. 

Public cloud deployments are not applicable to all instance types, however. 

The best course of action is a hybrid implementation of both on-premises and public cloud deployment.

What are the objectives of deploying Kubernetes cluster on-premise?

  • To configure kubectl
  • To deploy for demo purposes a simple master (single) and worker node (single) cluster. 
  • To use Helm to deploy WordPress to a cluster

What are the system requirements for deployment? 

  • x86 64-bit hardware
  • 100Mbs stable internet connection
  • Root access to each node
  • Supported OS on nodes: RHEL 7.2+ or Ubuntu 16.04 LTS
  • Nodes are connected in your network and Kublr Demo/Installer configured IP is accessible from these nodes (ping)
  • From these nodes, traffic to Kublr Demo/Installer on ports 9080 / 9443 should be allowed by firewall rules

There are also specific hardware recommendation on cluster, platform feature and other specs. Head over to their website for specific details. 

It is important for the Kublr Demo/Installer to be configured correctly so it will be accessible in the local network. Provide the correct IP address at the startup of the virtual machine. Failure to do so will require you to configure and re-run provisioning of firewall rules so that traffic can go through. 

Always trust the experts

Kubernetes has become the primary choice for deploying and managing containerized applications. In a recent post by Kublr, CircleCI has also been added as additional partner integrations, a testament to its rapid growth. 

To ensure proper deployment of Kubernetes clusters, rely on a team who are experts in the platform’s core concepts, architecture, underlying infrastructure, and deployment tools. See more at https://kublr.com/deploy-kubernetes-on-premise/
