Kismatic Enterprise Toolkit (KET): Design, Deployment and Operations System for Production Kubernetes Clusters

Join our mailing list for updates on new releases: https://groups.google.com/forum/#!forum/kismatic-users

Introduction

KET is a set of production-ready defaults and best practice tools for creating enterprise-tuned Kubernetes clusters. KET was built to make it simple for organizations who fully manage their own infrastructure to deploy and run secure, highly-available Kubernetes installations with built-in sane defaults for scalable cross-cluster networking, distributed tracing, circuit-breaking, request-level routing, cluster health-checking and much more!

KET operational tools include:

1. Kismatic CLI
   • Command-line control plane and lifecycle tool for installing and configuring Kubernetes on provisioned infrastructure.
2. Kismatic Inspector
   • Cluster health and validation utility for assuring that software and network configurations of cluster nodes are correct when installing Kubernetes.
3. Kuberang
   • Cluster build verification to ensure networking and scaling work as intended. This tool is used to smoke-test a newly built cluster.
4. Kismatic RPM & DEB Packages
   • Packages for installing Kubernetes and its dependencies, focused on specific roles in an HA cluster.
   • With these packages installed on a local repo, it is possible to use Kismatic to install Kubernetes on nodes that do not have access to the public internet.
5. Kismatic Provision
   • Quickly provision infrastructure on public clouds such as AWS and Packet. Makes building demo and development clusters a 2-step process.

KET Release Process

Basic Installation Instructions

Use the kismatic install command to work through installation of a cluster. The installer expects the underlying infrastructure to be accessible via SSH using Public Key Authentication.

The installation consists of three phases:

1. Plan: kismatic install plan
   1. The installer will ask basic questions about the intent of your cluster.
   2. The installer will produce a kismatic-cluster.yaml which you will edit to capture your intent.
2. Provision
   1. You provision your own machines
   2. You tweak your network
   3. Review the installation plan in kismatic-cluster.yaml and add information for each node.
3. Install: kismatic install apply
   1. The installer checks your provisioned infrastructure against your intent.
   2. If the installation plan is valid, Kismatic will build you a cluster.
   3. After installation, Kismatic performs a basic test of scaling and networking on the cluster

Using your cluster

KET automatically configures and deploys Kubernetes Dashboard in your new cluster. Open the link provided at the end of the installation in your browser to use it.

Simply use the kismatic dashboard command to open the dashboard

You may be prompted for credentials, use admin for the User Name and %admin_password% (from your kismatic-cluster.yaml file) for the Password.

The installer also generates a kubeconfig file required for kubectl, just follow the instructions provided at the end of the installation to use it.
