## K3s HA install for Prole (Pi cluster + local k3d agents)

This repository includes scripts to create an HA K3s control plane across Raspberry Pi hosts and attach local k3d agents.

Topology overview:
- raspberry.prole.org → first K3s server (embedded etcd)
- pi.prole.org → additional K3s server (recommended for HA)
- This host (developer machine) → local k3d agents that join the remote K3s server

Prerequisites:
- k3sup: https://github.com/alexellis/k3sup
- k3d: https://k3d.io/
- kubectl
- SSH access to the Pis (defaults assume user `pi` and key `~/.ssh/id_rsa`)

1) Install first K3s server on raspberry.prole.org
```bash
cd k3s
# Optional env overrides:
# export K3S_FIRST_SERVER_HOST=raspberry.prole.org
# export K3S_FIRST_SERVER_USER=pi
# export K3S_SSH_KEY=$HOME/.ssh/id_rsa
# export K3S_VERSION=v1.30.6+k3s1
# export K3S_EXTRA_ARGS="--cluster-init --tls-san raspberry.prole.org"
./install_k3s_first_server.sh
```

2) Join pi.prole.org as an additional HA server (optional but recommended)
```bash
cd k3s
# Optional env overrides:
# export K3S_EXISTING_SERVER_HOST=raspberry.prole.org
# export K3S_EXISTING_SERVER_USER=pi
# export K3S_ADDITIONAL_SERVER_HOST=pi.prole.org
# export K3S_ADDITIONAL_SERVER_USER=pi
# export K3S_SSH_KEY=$HOME/.ssh/id_rsa
# export K3S_VERSION=v1.30.6+k3s1
# export K3S_EXTRA_ARGS="--tls-san raspberry.prole.org --tls-san pi.prole.org"
./join_k3s_additional_server.sh
```

3) Get the K3s node token from the first server
```bash
cd k3s
# Optional env overrides:
# export K3S_SERVER_HOST=raspberry.prole.org
# export K3S_SERVER_USER=pi
# export K3S_SSH_KEY=$HOME/.ssh/id_rsa
TOKEN=$(./get_remote_k3s_node_token.sh)
echo "K3s token: $TOKEN"
```

4) Create a local k3d agents-only cluster that joins the remote K3s server
```bash
cd k3s
# Required: provide the token
export K3S_REMOTE_TOKEN="$TOKEN"
# Optional env overrides:
# export K3D_CLUSTER_NAME=prole-remote-agents
# export K3D_AGENTS=2
# export K3D_IMAGE=rancher/k3s:v1.30.6-k3s1
# export K3D_REGISTRY_CONFIG=$HOME/dev/prole/k3s/registries.yaml
# export K3S_REMOTE_SERVER_HOST=raspberry.prole.org
# export K3S_REMOTE_SERVER_PORT=6443
./create_k3d_join_remote_agents.sh
```

Notes:
- The scripts default to embedded etcd HA. For true quorum, use at least 3 servers where possible. With two servers, loss of one server can cause loss of quorum; consider adding a third server or running an external etcd.
- If you prefer an external datastore (e.g., MySQL/PG/etcd), adjust `K3S_EXTRA_ARGS` in the server install to set `--datastore-endpoint=...` and remove `--cluster-init`.
- The local k3d cluster creates only agents that connect to the remote control-plane; it does not run a separate control-plane locally.
