# city-hall Setup Guide
`city-hall` (`10.1.71.38`) is the Ansible/Terraform control node and admin jump box
for the `mk-labs` homelab. This document is the authoritative list of required software
and configuration.
## System
- **OS**: Ubuntu 24.04
- **User**: `wed` (passwordless sudo)
- **SSH key**: `~/.ssh/ansible` (used by Ansible and Terraform SSH agent)
- **Repo**: `/opt/git/homelab` (cloned from `git.mk-labs.cloud/rblundon/homelab`)
---
## Required Software
### Core Tools
| Tool | Purpose | Install |
|---|---|---|
| `git` | Source control | `sudo apt install git -y` |
| `terraform` | Infrastructure provisioning | See below |
| `ansible` | Configuration management | See below |
| `packer` | VM template creation | See below |
#### Terraform
```bash
wget -O- https://apt.releases.hashicorp.com/gpg | sudo gpg --dearmor -o /usr/share/keyrings/hashicorp-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hashicorp.list
sudo apt update && sudo apt install terraform -y
```
#### Ansible
```bash
sudo apt install pipx -y
pipx install ansible
pipx inject ansible netaddr
ansible-galaxy collection install effectivelywild.technitium_dns
```
#### Packer
```bash
sudo apt update && sudo apt install packer -y
```
---
### Talos Cluster Tools
Required for provisioning and managing the `fastpass` Talos Kubernetes cluster.
| Tool | Purpose | Install |
|---|---|---|
| `talhelper` | Talos cluster config generation | See below |
| `talosctl` | Talos cluster CLI | See below |
| `kubectl` | Kubernetes CLI | See below |
| `helm` | Kubernetes package manager | See below |
| `age` | Encryption key generation (used by SOPS) | `sudo apt install age -y` |
| `sops` | Secret encryption for `talsecret.sops.yaml` | See below |
#### talhelper
```bash
curl -fsSL https://i.jpillora.com/budimanjojo/talhelper! | bash
```
Verify:
```bash
talhelper --version
```
#### talosctl
```bash
curl -sL https://talos.dev/install | sh
```
Verify:
```bash
talosctl version --client
```
#### kubectl
```bash
curl -LO "https://dl.k8s.io/release/$(curl -sL https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
chmod +x kubectl
sudo mv kubectl /usr/local/bin/
```
Verify:
```bash
kubectl version --client
```
#### Helm
```bash
curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash
```
Verify:
```bash
helm version
```
#### SOPS
```bash
SOPS_VERSION=$(curl -s https://api.github.com/repos/getsops/sops/releases/latest | grep tag_name | cut -d '"' -f 4)
curl -LO "https://github.com/getsops/sops/releases/download/${SOPS_VERSION}/sops-${SOPS_VERSION}.linux.amd64"
chmod +x "sops-${SOPS_VERSION}.linux.amd64"
sudo mv "sops-${SOPS_VERSION}.linux.amd64" /usr/local/bin/sops
```
Verify:
```bash
sops --version
```
---
## SSH Agent
The SSH agent must be running and loaded with the Ansible key before running Terraform
or Ansible. Add to `~/.bashrc`:
```bash
eval $(ssh-agent) > /dev/null
ssh-add ~/.ssh/ansible 2>/dev/null
```
---
## SOPS / age Setup (first time only)
Required before running `talhelper genconfig` for the first time.
```bash
# Generate an age key pair
age-keygen -o ~/.config/sops/age/keys.txt
# Note the public key from the output, e.g.:
# Public key: age1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
# Create a .sops.yaml at the repo root referencing your public key
cat > /opt/git/homelab/.sops.yaml << EOF
creation_rules:
- path_regex: talos/talhelper/talsecret.sops.yaml
age: age1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
EOF
```
Generate and encrypt the secrets file (talhelper looks for `talsecret.sops.yaml` by default):
```bash
cd talos/talhelper
talhelper gensecret > talsecret.sops.yaml
sops -e -i talsecret.sops.yaml
```
---
## Terraform Notes
- Always run from the relevant module directory (e.g., `terraform/talos/cluster/`)
- State files live in `states/` within each module — never committed to git
- Sensitive vars passed via CLI, never in committed tfvars files
- The `!` in the Proxmox API token requires single quotes to prevent bash history expansion:
```bash
terraform apply \
-var-file="tfvars/fastpass.tfvars" \
-state="states/fastpass.tfstate" \
-var='proxmox_api_token=terraform@pve!terraform-token=<secret>' \
-var='unifi_password=<secret>' \
-var='technitium_api_token=<secret>'
```
---
## Ansible Notes
- Always run from the `ansible/` directory
- Roles path: `ansible/playbooks/roles/`
- SSH user: `wed`
- Vault password file: `~/.vault_pass` (not committed)
---
## Talos / talhelper Notes
- Config lives at `talos/talhelper/` in the repo
- Secrets file is named `talsecret.sops.yaml` (talhelper default) — SOPS-encrypted
- Network interface on Proxmox VMs is `ens18` (not `eth0`)
- `talosctl` config (`~/.talos/config`) is generated by talhelper — keep a backup
- Cluster endpoint: `https://10.1.71.65:6443` (VIP)
- Talos API endpoint: `https://10.1.71.65:50000`
- Initial `apply-config` requires `--extra-flags="--insecure"` (maintenance mode only)
- `bootstrap` only runs once — bootstraps etcd on `space-mountain`
---
## fastpass Cluster Bootstrap Runbook
Run from `talos/talhelper/` unless otherwise noted.
### 1. Provision VMs (Terraform)
```bash
cd terraform/talos/cluster
terraform apply \
-var-file="tfvars/fastpass.tfvars" \
-state="states/fastpass.tfstate" \
-var='proxmox_api_token=terraform@pve!terraform-token=<secret>' \
-var='unifi_password=<secret>' \
-var='technitium_api_token=<secret>'
```
### 2. Generate Talos Machine Configs
```bash
cd talos/talhelper
# First time only — generate and encrypt secrets
talhelper gensecret > talsecret.sops.yaml
sops -e -i talsecret.sops.yaml
# Generate machine configs (uses talsecret.sops.yaml automatically)
talhelper genconfig
```
### 3. Verify Nodes are in Maintenance Mode
```bash
talosctl -n 10.1.71.66 get discoveredvolumes \
--talosconfig clusterconfig/talosconfig --insecure
```
Confirm install disk is `/dev/sda`.
### 4. Apply Machine Configs
```bash
talhelper gencommand apply --extra-flags="--insecure" | bash
```
Nodes will install Talos to disk and reboot automatically.
### 5. Monitor Install
```bash
talosctl -n 10.1.71.66 --talosconfig clusterconfig/talosconfig dashboard
```
Wait until all nodes show `Running` state.
### 6. Bootstrap etcd (once only)
```bash
talhelper gencommand bootstrap | bash
```
Only run once — bootstraps etcd on `space-mountain`.
### 7. Get kubeconfig
```bash
talosctl --talosconfig clusterconfig/talosconfig \
--nodes 10.1.71.66 kubeconfig ~/.kube/config
```
### 8. Approve Worker CSRs
```bash
kubectl get csr
kubectl certificate approve $(kubectl get csr --no-headers | awk '{print $1}')
```
### 9. Install Cilium (CNI)
```bash
helm repo add cilium https://helm.cilium.io/
helm repo update
helm install cilium cilium/cilium \
--namespace kube-system \
--set ipam.mode=kubernetes \
--set routingMode=tunnel \
--set tunnelProtocol=vxlan \
--set kubeProxyReplacement=true \
--set k8sServiceHost=10.1.71.65 \
--set k8sServicePort=6443 \
--set securityContext.capabilities.ciliumAgent="{CHOWN,KILL,NET_ADMIN,NET_RAW,IPC_LOCK,SYS_ADMIN,SYS_RESOURCE,DAC_OVERRIDE,FOWNER,SETGID,SETUID}" \
--set securityContext.capabilities.cleanCiliumState="{NET_ADMIN,SYS_ADMIN,SYS_RESOURCE}" \
--set cgroup.autoMount.enabled=false \
--set cgroup.hostRoot=/sys/fs/cgroup
```
Note: The explicit `securityContext.capabilities` flags are required for Talos — Talos
restricts privileged container capabilities by default. The `cgroup.autoMount.enabled=false`
and `cgroup.hostRoot` flags are required because Talos manages cgroups itself.
### 10. Verify Cluster
```bash
kubectl get nodes
kubectl get pods -n kube-system
```
All nodes should show `Ready`. Cilium pods should be `Running`.
### 11. Post-Install HA Setup
See output of `terraform output` for the full HA registration commands.
Register VMs with Proxmox HA and add to node-affinity rules once the
cluster is stable and the ISO is no longer needed for boot.

── Post-Cluster-Install: HA Setup ──────────────────────────────────────────
Once Talos is fully installed and running (ISO no longer needed for boot),
complete the following steps:
1. Register each VM with the Proxmox HA manager:
ha-manager add vm:71066 --state started
ha-manager add vm:71067 --state started
ha-manager add vm:71068 --state started
ha-manager add vm:71069 --state started
ha-manager add vm:71070 --state started
ha-manager add vm:71071 --state started
2. Add VMs to the existing node-affinity rules (check current resources
first with pvesh get /cluster/ha/rules/<rule>):
prefer_main-street-usa (space-mountain:71066, jungle-cruise:71069):
pvesh set /cluster/ha/rules/prefer_main-street-usa \
--type node-affinity \
--resources "<existing>,vm:71066,vm:71069"
prefer_tomorrowland (big-thunder-mountain:71067, haunted-mansion:71070):
pvesh set /cluster/ha/rules/prefer_tomorrowland \
--type node-affinity \
--resources "<existing>,vm:71067,vm:71070"
prefer_fantasyland (splash-mountain:71068, peter-pans-flight:71071):
pvesh set /cluster/ha/rules/prefer_fantasyland \
--type node-affinity \
--resources "<existing>,vm:71068,vm:71071"
3. Eject the Talos ISO from each VM in the Proxmox UI or via:
qm set <vmid> --ide2 none
