# proxmox-talos-opentofu
|
|
Proof of concept project using [OpenTofu](https://opentofu.org/) to install a Kubernetes cluster on a Proxmox VE
|
|
hypervisor using [Talos Linux](https://www.talos.dev/).
|
|
|
|
## Requirements
|
|
You need to have installed on your local machine:
|
|
* [OpenTofu](https://opentofu.org/)
|
|
* [kubectl](https://kubernetes.io/docs/reference/kubectl/) (for testing and cluster interaction)
|
|
|
|
## Provisioning
|
|
The project is grouped in two modules:
|
|
* proxmox: provisioning of virtual machines, operating systems and Kubernetes cluster
|
|
* kubernetes: provisioning of Kubernetes cluster resources
|
|
|
|
### Proxmox VE
|
|
So you want first to provision the Proxmox part: create a `configuration.auto.tfvars` file based on the example and
|
|
edit it so it suits your needs:
|
|
```shell
|
|
cd proxmox
|
|
cope configuration.auto.tfvars.example configuration.auto.tfvars
|
|
vim configuration.auto.tfvars
|
|
```
|
|
Then apply the configuration using OpenTofu:
|
|
```shell
|
|
tofu init
|
|
tofu plan
|
|
tofu apply
|
|
```
|
|
You can then grab and move the kube config file for Kubernetes provisioning like so:
|
|
```shell
|
|
tofu output kubeconfig -raw > ~/.kube/config
|
|
chmod 600 ~/.kube/config
|
|
```
|
|
Test if your cluster access works by listing the nodes:
|
|
```shell
|
|
kubectl get nodes
|
|
```
|
|
You might need to wait a bit until the cluster comes up. Proceed with the next step when all nodes are in the `ready`
|
|
state.
|
|
|
|
### Kubernetes
|
|
Secondly, you can provision the Resources inside the Kubernetes cluster. Currently, this project just installs
|
|
ArgoCD in the `argocd` namespace in the cluster. You can then add on top of this by adding your own resources
|
|
using the GitOps approach.
|
|
You need to create a `configuration.auto.tfvars` file as well first:
|
|
```shell
|
|
cd kubernetes
|
|
cope configuration.auto.tfvars.example configuration.auto.tfvars
|
|
vim configuration.auto.tfvars
|
|
```
|
|
Then do the provisiong with OpenTofu:
|
|
```shell
|
|
tofu init
|
|
tofu plan
|
|
tofu apply
|
|
```
|
|
