Deploying Kubernetes

Kubernetes

Kubernetes is an open-source container orchestration system for automating software deployment, scaling, and management.Originally designed by Google, the project is now maintained by a worldwide community of contributors, and the trademark is held by the Cloud Native Computing Foundation.

Deploy Kubernetes

• Login to Enbuild -Enbuild
• Click on the Home
• Select the Kubernetes
• Choose the component RKE2 from the DISTRO category and click on the VALUES tab and provide the Credentials

RKE2#

RKE2, also known as RKE Government, is Rancher’s next-generation Kubernetes distribution.

It is a fully conformant Kubernetes distribution that focuses on security and compliance within the U.S. Federal Government sector.

EKS#

Amazon Elastic Kubernetes Service (Amazon EKS) is a managed Kubernetes service to run Kubernetes in the AWS cloud and on-premises data centers. In the cloud, Amazon EKS automatically manages the availability and scalability of the Kubernetes control plane nodes responsible for scheduling containers, managing application availability, storing cluster data, and other key tasks. With Amazon EKS, you can take advantage of all the performance, scale, reliability, and availability of AWS infrastructure, as well as integrations with AWS networking and security services. On-premises, EKS provides a consistent, fully-supported Kubernetes solution with integrated tooling and simple deployment to AWS Outposts, virtual machines, or bare metal servers.
