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
installed on your machine.
golang -v 1.11.5
is preferred. To install kind, run these commands (it takes a while):
go get -u sigs.k8s.io/kind kind create cluster
Then confirm kind cluster is available:
kind get clusters
. Check its version by running this command:
If you find you are running
from Docker, try
or reorder path environment variable.
and kind are ready, open bash console and run these commands:
export KUBECONFIG=”$(kind get kubeconfig-path)” kubectl cluster-info
is properly set up, some information will be shown.
Now you are ready to proceed. Yay!
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.
files are prepared, layout them as following:
k8s-wp/ kustomization.yaml mysql-deployment.yaml wordpress-deployment.yaml
Then apply them to your cluster:
cd k8s-wp kubectl apply -k ./
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
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 🙂
