k8s-aws-terraform-cluster VS k3s-oci-cluster

git clone https://github.com/garutilorenzo/k8s-aws-terraform-cluster cd k8s-aws-terraform-cluster/example/

This terraform module will deploy a high available Kubernetes (K8s) cluster on Amazon AWS, using mixed on-demand and spot instances. K8s is installed through kubeadm ad usesContainerd as CRI and Flannel as CNI. You can also install longhorn for the persistent storage and nginx ingress controller for the ingress rules. Please note, this is only an example on how to Deploy a Kubernetes cluster. For a production environment you should use EKS or ECS.

After you've cloned the repo, go to oci/terraform.tfvars and edit all values with the ones from your notes file. This build uses the great terraform configuration files from this repo of garutilorenzo (using version 2.2; if you have errors running all of this, you should check what changed in this repo since v2.2, or 01.02.23). You can read here if you want to customize your configuration and edit the main.tf file. This is the diagram that garutilorenzo made and how your deployment will look like (this tutorial is without Longhorn and ArgoCD, with 1 server nodes + 3 worker nodes and with ingress controller set as Traefik): *note - I've got some problems with clock of WSL2 not being synced to Windows clock. And provisioning didn't worked so if you receive clock errors too, verify your time with datecommand, if out of sync just run sudo hwclock -s or sudo ntpdate time.windows.com. Now just run terraform plan and then terraform apply. If everything was ok you should have your resources created.

This new release v2.0 introduces:

We use the same stack used in this repository. This stack need longhorn and nginx ingress.

This module will deploy a Kubernetes cluster for free, using K3s and Oracle always free resources.
