# Home Cluster

## TODO

- Netboot: https://www.sidero.dev/v0.5/getting-started/prereq-dhcp/

## Setup

> Source: https://www.talos.dev/v1.1/introduction/getting-started/

- 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
- Apply the control plane config to the initial node
  - `talosctl apply-config --insecure --nodes "$INITIAL_NODE_ADDR" --file controlplane.yaml`
  - You will need to wait a bit for the configuration to be applied, Talos to
    install itself, for the node to reboot, and for post-boot initialization
- Setup the client to communicate with the newly-configured node
  - `talosctl --talosconfig=./talosconfig config endpoint "$INITIAL_NODE_ADDR"`
    - Optionally also make this the default with `talosctl config merge ./talosconfig`
- Bootstrap the cluster
  - `talosctl bootstrap --nodes "$INITIAL_NODE_ADDR"`
  - You will need to wait a bit for Kubernetes to initialize
- Pull down the kubeconfig
  - `talosctl kubeconfig`

Once the cluster has finished initializing _and starting up_, you should be
able to `kubectl get nodes`.

## Adding Nodes

- Boot the Talos ISO on the target node
- Apply the appropriate configuration to the target node
  - `talosctl apply-config --insecure --nodes "$TARGET_NODE_ADDR" --file controlplane.yaml`
  - You will need to wait a bit for Kubernetes to initialize, start up, and
    then join the cluster

## Storage

- TODO?

## Load Balancing

I can _probably_ handle this with my router?

- TODO?
