Provisioning is done with [OpenTofu](https://opentofu.org/).
Kubernetes cluster features:
* Talos Linux v1.11.6
* Kubernetes v1.34.2
* no kube-proxy
* [Cilium v1.18.3](https://cilium.io/) as Container Network Interface (CNI)
@@ -22,70 +23,117 @@ You need to have installed on your local machine:
* [kubectl](https://kubernetes.io/docs/reference/kubectl/) (for testing and cluster interaction)
## Provisioning
The project is grouped in two sections:
The project is grouped in three sections:
* proxmox: provisioning of virtual machines, operating systems and Kubernetes cluster
* kubernetes: provisioning of Kubernetes cluster resources
* argocd: provisioning of Kubernetes resources using GitOps, can be installed with `install_argocd_app_of_apps` flag
This way you can choose to only provision the cluster itself or/and provision Kubernetes resources and bootstrap
also [ArgoCD](https://argoproj.github.io/cd/).
You will have an [ArgoCD](https://argoproj.github.io/cd/) instance running in the cluster eventually. You can then
install your applications using the GitOps approach.
install your applications using the GitOps approach. Have a look at `install_argocd_app_of_apps` and the related
configuration variables for further options.
The main idea is to configure the Kubernetes cluster and also the [ArgoCD](https://argoproj.github.io/cd/) bootstrap with infrastructure as code
using [OpenTofu](https://opentofu.org/). So it can be rolled out very quickly and consistently. All other Kubernetes resources are then
provisioned using a git repository via the GitOps approach.
Usually you want to keep your cluster infrastructure and [ArgoCD](https://argoproj.github.io/cd/) bootstrap separate from your Kubernetes resources.
That way you have everything decoupled and migrate to a new cluster infrastructure more easily. I added the `argocd`
directory mainly for demonstration purposes.
### Proxmox VE
So you want first to provision the Proxmox part: create a `configuration.auto.tfvars` file based on the example and
First step is 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
$ 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
$ 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
$ tofu output kubeconfig -raw > ~/.kube/config
$ chmod 600 ~/.kube/config
```
Test if your cluster access works by listing the nodes:
```shell
kubectl get nodes
$ kubectl get nodes
NAME STATUS ROLES AGE VERSION
your-cp-0 Ready control-plane 5d v1.34.2
your-worker-0 Ready <none> 5d v1.34.2
```
You might need to wait a bit until the cluster comes up. Proceed with the next step when all nodes are in the `ready`
You might need to wait a bit until the nodes come 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:
Secondly, you can provision the resources inside the Kubernetes cluster. You have a couple of options to choose
from. All options can be configured using variables in `configuration.auto.tfvars`:
1. **Quick start**: installs Cilium LB config, ArgoCD, Ingress without TLS (default settings) with OpenTofu. [ArgoCD](https://argoproj.github.io/cd/) is
available on http://argocd.local.
* install_cilium_lb_config = true
* argocd_domain = "argocd.local"
* argocd_server_insecure = true
* argocd_ingress_enabled = true
* install_argocd_app_of_apps = false
* install_argocd_app_of_apps_git_repo_secret = false
2. **GitOps using your own repository**: installs ArgoCD, no Cilium LB config, no Ingress and the Kubernetes resources in
the repository you specify in `argocd_app_of_apps_source`. Credentials for a private repository can be configured
and installed with OpenTofu using `install_argocd_app_of_apps_git_repo_secret` and the related variables:
* install_cilium_lb_config = false
* argocd_domain = "yourpublicdomain.com"
* argocd_server_insecure = true
* argocd_ingress_enabled = false
* install_argocd_app_of_apps = true
* argocd_app_of_apps_source = YOUR SOURCE SETTINGS
* install_argocd_app_of_apps_git_repo_secret = true
* argocd_app_of_apps_git_repo_secret_url = "https://github.com/you/yourrepo.git"
* argocd_app_of_apps_git_repo_secret_password_or_token = "github_pat_OLImf09435459hfjoi9m435298524jtfjn45i8tmnmds329023jdhn"
These are two use cases I envision here. Please regard them as examples. Of course, you can combine the variables to
any other setup which suits your needs.
For doing a **GitOps quick start** you can fork this repository and point the `argocd_app_of_apps_source` to the
`argocd` directory of your newly forked repository. This way you can make use of the example Kubernetes resources in
`argocd` directory and edit them to match your infrastructure.
Create a `configuration.auto.tfvars` like so and edit it to your liking:
```shell
cd kubernetes
cope configuration.auto.tfvars.example configuration.auto.tfvars
vim configuration.auto.tfvars
$ cd kubernetes
$ cope configuration.auto.tfvars.example configuration.auto.tfvars
$ vim configuration.auto.tfvars
```
Then do the provisiong with OpenTofu:
Then do the provisioning with OpenTofu:
```shell
tofu init
tofu plan
tofu apply
$ tofu init
$ tofu plan
$ tofu apply
```
You can grab the [ArgoCD](https://argoproj.github.io/cd/) initial admin password with `kubectl` afterwards:
```shell
$ kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath='{.data.password}' | base64 -d
```
The [ArgoCD](https://argoproj.github.io/cd/) instance should be available under the `argocd_domain` you configured
in your `configuration.auto.tfvars` file i.e., http://argocd.local.
## Roadmap
My todo list for the GitOps part:
* bootstrap a certificate authority
* add storage options i. e. NFS, Ceph, local
Proxmox part:
* make node resources configurable (CPU, memory, etc.)
* make version upgrades possible for Kubernetes Nodes with OpenTofu
GitOps part:
* add storage options i.e. Ceph, local
* add Keycloak operator and Keycloak instance for SSO
* add Prometheus/Grafana for monitoring
* add Alloy/Loki for logging
* add Velero for disaster recovery
I am happy to receive pull requests for any improvements.
