This tutorial is part 2 of our Terraform/K3S Kubernetes series You need to have looked at this Video first: https://www.youtube.com/watch?v=4DiWQToF6FQ 1. Given we have these Nginx Manifests nginx-deployment.yaml: apiVersion: apps/v1 kind: Deployment metadata: name: nginx-deployment namespace: mynginx spec: selector: matchLabels: app: nginx replicas: 4 template: metadata: labels: app: nginx spec: containers: - name: nginx image: nginx:1.14.2 ports: - containerPort: 80 nginx-service.yaml apiVersion: v1 kind: Service metadata: name: nginx namespace: mynginx labels: run: nginx spec: ports: - port: 80 selector: app: nginx 2.

This tutorial is part 1 of our Terraform/K3S Kubernetes series We will provide a link next week to the Video for Part 2 as soon as we publish it Preface In this lesson we are going to do the following: Create an Ubuntu VM using our Ubuntu Server Template in our Proxmox VM Server Download the K3S_Auto_Cluster_Generator from our GitHub Repository and Configure it for our Vm servers Create a K3S Kubernetes Cluster using our K3S_Auto_Cluster_Generator Install Helm on our K3S Master Node Ubuntu VM Server Install Terraform on our K3S Master Node Ubuntu VM Server Create and Apply a simple Terraform Kubernetes Namespace project to work and deploy to our K3S Kubernetes cluster We will have learned how to use the Kubernetes Provider for Terraform to deploy infrastructure changes in our K3S Kubernetes Cluster
