## TODO
- Netboot: https://www.sidero.dev/v0.5/getting-started/prereq-dhcp/
- Should be able to use `dnsmasq` for this?
## Setup
You will need the following:
- `argocd`
- `talosctl`
- `kubectl`
### Networking Preparations
- Internally:
- Add a DNS entry for the cluster endpoint (router's `/etc/hosts` and
`dnsmasq`) to point to the initial node
- If using MetalLB, Ensure that ARP tables for receiving machines will have
a route matching your desired CIDR
- Externally:
- Add a DNS entry for the cluster endpoint to point to the router
- Setup the router to forward external requests to the initial node
### Initialize Kubernetes Cluster

- Boot the Talos ISO on the initial node
- Prepare networking
- Internally:
- Add a DNS entry for the cluster endpoint (router's `/etc/hosts` + `dnsmasq`) to point to the initial node
- Externally:
- Add a DNS entry for the cluster endpoint to point to the router
- Setup the router to forward external requests to the initial node
- If you are not using _this_ configuration:
- `talosctl gen config "cluster-name" "cluster-endpoint"`
- Edit files as needed
- Prepare your talos config
- `cd talos`
- Or if you are not using _this_ configuration:
- `talosctl gen config "cluster-name" "cluster-endpoint"`
- Edit files as needed

- You will need to wait a bit for Kubernetes to initialize, start up, and
then join the cluster
- Add the node to `talosconfig` as needed
- For another control plane node: `talosctl --talosconfig=./talosconfig config endpoint "$TARGET_NODE_ADDR"`
- Otherwise: `talosctl --talosconfig=./talosconfig config endpoint "$TARGET_NODE_ADDR"` (untested)
- Add the node to the internal DNS entry for the cluster endpoint

Once the cluster has finished initializing _and starting up_, you should be
able to `kubectl get nodes`.
### Setup GitOps
Now we should avoid changing the cluster manually so that all changes are
captured in source control. We do this with flux:
```bash
kubectl create namespace argocd
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
```
