Deploy a production-grade Kubernetes cluster on your local machine with a single command!
This post will demonstrate how to launch a local k8s development environment leveraging k3s.
K3s is a lightweight production-grade Certified Kubernetes distribution. More info. can be found at https://k3s.io/.
Prerequisites To Deploying Local Dev Environment
- Vagrant (tested with 2.1.2)
- VirtualBox (tested with 5.2.30)
- Vagrantfile (clone my GitHub repo, found here)
Vagrant Up!
After satisfying prerequisites navigate to directory containing Vagrantfile and issue “vagrant up”. After a few minutes you should have a three node cluster up and running! The k8s cluster is configured to leverage Flannel for networking, etcd to store data and should be similar to the below diagram.
kubectl from localhost copy k3s.yaml contents to ~/.kube/config (k3s.yaml copied to local vagrant directory)
C:\>kubectl get nodes -o wide
