If you've spent days (or even weeks?) trying to spin up a Kubernetes cluster for learning purposes or to test your application, then your worries are over. Spawned from a Kubernetes Special Interest Group, KIND is a tool that provisions a Kubernetes cluster running IN Docker. From the docs: kind is a tool for running local Kubernetes clusters using Docker container "nodes". kind is primarily designed for testing Kubernetes 1.11+, initially targeting the . conformance tests Installing KIND As it is built using go, you will need to make sure you have the latest version of installed on your machine. golang According to the k8s , is preferred. To install kind, run these commands (it takes a while): docs golang -v 1.11.5 go get -u sigs.k8s.io/kind kind create cluster Then confirm kind cluster is available: kind get clusters Setting up kubectl Also, install the latest using or . The latest Docker has Kubernetes feature but it may come with older . Check its version by running this command: kubernetes-cli Homebrew Chocolatey kubectl kubectl version Make sure it shows or above. If you find you are running from Docker, try or reorder path environment variable. GitVersion: "v1.14.1" kubectl brew link Once and kind are ready, open bash console and run these commands: kubectl KUBECONFIG=”$(kind get kubeconfig-path)” kubectl cluster-info export If is properly set up, some information will be shown. Now you are ready to proceed. Yay! kind Deploying first application What should we deploy on the cluster? We are going to attempt deploying Cassandra since the docs have a pretty decent walk-through on it. First of all, download and for later. Then create kustomization.yaml by running two cat commands. cassandra-service.yaml cassandra-statefulset.yaml Once those files are prepared, layout them as following: yaml k8s-wp/ kustomization.yaml mysql-deployment.yaml wordpress-deployment.yaml Then apply them to your cluster: k8s-wp kubectl apply -k ./ cd Validating (optional) Get the Cassandra Service. kubectl get svc cassandra The response is: NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE cassandra ClusterIP None <none> 9042/TCP 45s Note that Service creation might have failed if anything else is returned. Read for common issues. Debug Services Finishing up That's really all you need to know to get started with KIND, I hope this makes your life a little easier and lets you play with Kubernetes a little bit more :) About the author - Sudip is a Solution Architect with more than 15 years of working experience, and is the founder of Javelynn .
