# CLAUDE.md # proxmox-infra
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository. This file provides guidance to Claude Code when working in `01-proxmox-infra`. See the [repo-root CLAUDE.md](../CLAUDE.md) for shared conventions, deployment order, and CI/CD.
## Project Overview ## Project Overview
This is a Pulumi TypeScript project (`proxmox-infra`) for provisioning VMs and LXC containers in Proxmox using the `@muhlba91/pulumi-proxmoxve` provider. The stack name is `dev`. Pulumi TypeScript project provisioning VMs and LXC containers in Proxmox using the `@muhlba91/pulumi-proxmoxve` provider, plus pfSense DHCPv4 static mappings via a locally-bundled `@pulumi/pfsense` SDK.
## Common Commands ## Common Commands
```bash ```bash
# Install dependencies # Install deps and compile the bundled pfSense SDK
npm install npm install
# Preview infrastructure changes # Sync Pulumi state with actual Proxmox state — run before `up` if VMs were
pulumi preview # changed manually in the Proxmox GUI
# Sync Pulumi state with actual Proxmox state (run before up if resources were changed manually)
pulumi refresh --yes pulumi refresh --yes
# Deploy infrastructure
pulumi refresh --yes && pulumi up --yes pulumi refresh --yes && pulumi up --yes
# Destroy infrastructure
pulumi destroy
# View current stack outputs
pulumi stack output
# View stack config
pulumi config
``` ```
## Architecture ## Architecture
- **Entry point**: `index.ts` — all Pulumi resources are declared here - **Entry point**: `index.ts` — all resources declared here.
- **Provider**: `@muhlba91/pulumi-proxmoxve` v8.x — community Proxmox provider (not an official Pulumi provider) - **Providers**: two `@muhlba91/pulumi-proxmoxve` providers — `pveProvider` (node `pve`) and `pveBckpProvider` (node `pve-bckp`). Always pass the correct provider when adding resources.
- **Stack**: `dev` — configured in `Pulumi.dev.yaml` - pfSense SDK lives in `sdks/pfsense/` (gitignored, regenerated by `npm install` / CI via `pulumi package add terraform-provider marshallford/pfsense 0.22.0`).
- **Runtime**: Node.js with `npm`, TypeScript compiled to `bin/` (excluded from git)
## CI/CD (Gitea Actions) ## CI/CD
Workflow file: `../.gitea/workflows/deploy-proxmox-infra.yaml` Workflow: `../.gitea/workflows/01-deploy-proxmox-infra.yaml`. Secret: `PROXMOX_INFRA_PULUMI_DEV_YAML`. In addition to the shared pattern, this workflow regenerates the pfSense SDK (`pulumi package add terraform-provider marshallford/pfsense 0.22.0`) before preview/deploy.
Triggers: push to `main` and pull requests targeting `main`, scoped to changes under `proxmox-infra/**` or `.gitea/workflows/**`.
- **Pull request** → `pulumi preview` (no changes deployed)
- **Push to main** → `pulumi refresh` then `pulumi up`
Secrets required in Gitea (`Settings → Actions → Secrets`):
- `PULUMI_BACKEND_URL` — PostgreSQL connection string for the self-hosted state backend
- `PULUMI_CONFIG_PASSPHRASE` — passphrase used to decrypt secrets in `Pulumi.dev.yaml`
- `PULUMI_DEV_YAML` — base64-encoded content of `Pulumi.dev.yaml`; update manually whenever the file changes: `base64 -w 0 Pulumi.dev.yaml`
## Key Notes
- Credentials for both Proxmox nodes are stored as encrypted secrets in `Pulumi.dev.yaml` and decrypted at runtime using `PULUMI_CONFIG_PASSPHRASE`. Do not pass Proxmox credentials via environment variables — the code uses `config.requireSecret()`.
- There are two Proxmox providers: `pveProvider` (main node `pve`) and `pveBckpProvider` (backup node `pve-bckp`). Always pass the correct provider when adding resources.
- `Pulumi.dev.yaml` contains the encryption salt — never delete it or secrets become unrecoverable.
- TypeScript is compiled with strict mode, `nodenext` module resolution, and `noImplicitReturns` — all functions must have explicit return types when TypeScript cannot infer them.
- Don't add a co-author when committing to git.

# k8s-bootstrap # k8s-bootstrap
Bootstraps a k3s cluster on the 5 Proxmox VMs created by `proxmox-infra`. Starts VMs via the Proxmox REST API, then provisions k3s over SSH using `@pulumi/command` remote.Command.

6. Reads `/etc/rancher/k3s/k3s.yaml` from master-1 via SSH, patches server URL, exports as secret stack output 6. Formats the workers' dedicated `scsi1` disk (ext4, if not already formatted) and mounts it at `/mnt/longhorn-extra` (via `/etc/fstab`) — this is the disk `03-k8s-infra` later registers as an extra Longhorn disk, to keep Longhorn off the root filesystem and avoid `DiskPressure`
7. Reads `/etc/rancher/k3s/k3s.yaml` from master-1 via SSH, patches the server URL, and exports it as the secret stack output `kubeconfig`
VM IDs and the CI runner SSH private key are read automatically from the `proxmox-infra` stack output via `StackReference` — no manual setup needed for those.

Proxmox credentials (`pve1Endpoint`, `pve1ApiToken`, `pve2Endpoint`, `pve2ApiToken`) are read automatically from `proxmox-infra` via StackReference — do **not** set them here.
## Deployment order
`proxmox-infra` must be deployed **before** k8s-bootstrap. The proxmox-infra stack exports the Proxmox credentials and VM IDs that k8s-bootstrap reads via StackReference. If proxmox-infra hasn't been re-deployed after its latest code changes, those outputs won't exist and k8s-bootstrap will fail.
In CI, both workflows run as previews on PRs (no deploy). Trigger `workflow_dispatch` on `deploy-proxmox-infra` first, then run k8s-bootstrap.
After setting config, re-encode `Pulumi.dev.yaml` and update the Gitea secret `K8S_BOOTSTRAP_DEV_YAML`:
```bash
base64 -w 0 Pulumi.dev.yaml
# Copy output → Gitea → Settings → Actions → Secrets → K8S_BOOTSTRAP_DEV_YAML
```
## Prerequisites ## Prerequisites
`proxmox-infra` must be deployed first. On first `pulumi up`, it generates an ed25519 SSH keypair via `@pulumi/tls`, writes the public key into every VM's cloud-init, and exports the private key as a secret stack output. VMs must be re-provisioned (or the public key manually added to `~/.ssh/authorized_keys`) before k8s-bootstrap can SSH in. `proxmox-infra` must be deployed first. On its first `pulumi up` it generates an ed25519 SSH keypair via `@pulumi/tls`, writes the public key into every VM's cloud-init, and exports the private key as a secret stack output. VMs must be re-provisioned (or have the public key manually added to `~/.ssh/authorized_keys`) before this stack can SSH in.
## After first run ## CI/CD
The `kubeconfig` stack output must be propagated to `k8s-infra` and `k8s-apps`: Workflow: `../.gitea/workflows/02-deploy-k8s-bootstrap.yaml`. Secret: `K8S_BOOTSTRAP_PULUMI_DEV_YAML`. Deploy is manual (`workflow_dispatch`) — re-running this stack restarts the bootstrap sequence against live VMs.
```bash
KUBECONFIG=$(pulumi stack output kubeconfig --show-secrets)
cd ../k8s-infra && pulumi config set --secret kubeconfig "$KUBECONFIG"
cd ../k8s-apps && pulumi config set --secret kubeconfig "$KUBECONFIG"
```
Then re-encode each `Pulumi.dev.yaml` and update the corresponding Gitea secrets
(`K8S_INFRA_DEV_YAML`, `K8S_APPS_DEV_YAML`):
```bash
base64 -w 0 k8s-infra/Pulumi.dev.yaml
base64 -w 0 k8s-apps/Pulumi.dev.yaml
```
## k8s-infra config changes (democratic-csi → NFS CSI)
The `k8s-infra` stack no longer needs `truenasApiKey` or `truenasDataset`.
Replace them with:
```bash
cd ../k8s-infra
pulumi config set truenasHost "192.168.1.x"
pulumi config set truenasNfsPath "/mnt/tank/k8s"
# Remove old keys if present:
pulumi config rm truenasApiKey
pulumi config rm truenasDataset
```
## TrueNAS one-time setup (before deploying k8s-infra)
1. Create a dataset: `tank/k8s`
2. Add an NFS share for that dataset
3. In Network → Allowed Networks, permit `192.168.1.0/24`
4. No API key required — the NFS CSI driver connects directly via NFS protocol

# k8s-infra
This file provides guidance to Claude Code when working in `03-k8s-infra`. See the [repo-root CLAUDE.md](../CLAUDE.md) for shared conventions, deployment order, and CI/CD.
Cluster-level infrastructure for the k3s homelab cluster, deployed via Helm and `@pulumi/kubernetes`. Reads `kubeconfig` from `k8s-bootstrap` via StackReference.
## Common Commands
```bash
npm install
pulumi refresh --yes && pulumi up --yes
```
CI installs the `helm` CLI (`azure/setup-helm`) before running Pulumi.
## Architecture
| Component | What it does |
| --- | --- |
| NFS CSI Driver | `csi-driver-nfs` Helm chart — enables NFS-backed PVCs |
| `truenas-nfs` StorageClass | Backed by an NFS share on TrueNAS (`Retain` reclaim policy) |
| cert-manager | Certificate lifecycle management |
| `letsencrypt-prod` ClusterIssuer | DNS-01 via Cloudflare, issues Let's Encrypt TLS certs |
| Longhorn | Default block storage (`longhorn` StorageClass, 2 replicas) — used by app/monitoring PVCs. Worker nodes get an extra `longhorn-extra` disk at `/mnt/longhorn-extra` (a dedicated mount set up by `k8s-bootstrap`, patched onto the Longhorn `Node` CR here) so Longhorn data stays off the root disk and doesn't cause `DiskPressure`. `nodeDownPodDeletionPolicy` deletes both the StatefulSet and Deployment pod on node-down so stateful workloads reschedule automatically |
| kube-vip | DaemonSet that ARP-announces a virtual IP for LoadBalancer Services |
| kube-vip-cloud-provider | Allocates LoadBalancer IPs from a single-address pool (`kubeVipAddress`) — k3s's built-in ServiceLB is not used |
| `traefik` ServicePatch | Pins Traefik's LoadBalancer IP to `kubeVipAddress` |
**Export**: `nfsStorageClass = "truenas-nfs"`.
## Required Pulumi config
```bash
pulumi config set --secret truenasHost <truenas-ip>
pulumi config set --secret truenasNfsPath /mnt/pool/k8s
pulumi config set --secret cloudflareApiToken <cf-token>
pulumi config set --secret letsencryptEmail <your-email>
pulumi config set --secret kubeVipAddress <vip-ip>
pulumi config set kubeVipInterface <e.g. eth0>
```
`kubeconfig` is read automatically via StackReference — do not set it here.
## TrueNAS one-time setup (before deploying)
1. Create dataset `pool/k8s`
2. Add an NFS share for that dataset:
- ACL type: POSIX/generic Unix permissions (not SMB/NFSv4 ACLs) on TrueNAS SCALE
- Maproot User / Group: `root` / `root`
- Allowed Hosts/Networks: restrict to the k3s node IPs/CIDR
3. In Network → Allowed Networks, permit your LAN subnet (e.g. `192.168.1.0/24`)

# k8s-apps
This file provides guidance to Claude Code when working in `04-k8s-apps`. See the [repo-root CLAUDE.md](../CLAUDE.md) for shared conventions, deployment order, and CI/CD.
Application workloads for the k3s homelab cluster. Reads `kubeconfig` from `k8s-bootstrap` via StackReference.
## Common Commands
```bash
npm install
pulumi up --yes
```
## Architecture
- **heimdall** — application dashboard (`lscr.io/linuxserver/heimdall`), namespace `heimdall`
- PVC `heimdall-config` (50Mi, `longhorn` StorageClass)
- Deployment + ClusterIP Service
- Ingress (`traefik` class, `cert-manager.io/cluster-issuer: letsencrypt-prod`) at `heimdall.<domain>`
- deployed with one replica because heimdall is not able to work with multiple replicas. Works with node failure detection and automatic rescheduling.
**Export**: `domain` (secret) — consumed by `monitoring` via StackReference for its own ingress hostnames.
## Required Pulumi config
```bash
pulumi config set --secret domain <your-domain>

# monitoring
This file provides guidance to Claude Code when working in `05-monitoring`. See the [repo-root CLAUDE.md](../CLAUDE.md) for shared conventions, deployment order, and CI/CD.
Monitoring stack (Prometheus + Grafana) via the `kube-prometheus-stack` Helm chart. Reads `kubeconfig` from `k8s-bootstrap` and `domain` from `k8s-apps`, both via StackReference.
## Common Commands
```bash
npm install
pulumi up --yes
```
## Architecture
- Namespace `monitoring`
- `kube-prometheus-stack` Helm release (chart v86.2.0)
- Grafana: ingress at `grafana.<domain>` (`traefik`, `letsencrypt-prod`), `longhorn` PVC (2Gi)
- Prometheus: `longhorn` PVC (20Gi) via `volumeClaimTemplate`
- Alertmanager disabled
## Key Notes
- The `monitoring` namespace and the Helm release both use the Pulumi `import` resource option (`monitoring`, `monitoring/kube-prometheus-stack`) — they were adopted from pre-existing cluster resources rather than created fresh. Be careful with renames or changes that would force a replace.
## Required Pulumi config
```bash
pulumi config set --secret grafanaAdminPassword <password>
```
## CI/CD
Workflow: `../.gitea/workflows/05-deploy-monitoring.yaml`. Secret: `MONITORING_PULUMI_DEV_YAML`.

# CLAUDE.md
This file provides guidance to Claude Code when working anywhere in this repository. Each stack directory (`01-proxmox-infra`, `02-k8s-bootstrap`, etc.) has its own `CLAUDE.md` with stack-specific commands and architecture — Claude Code loads both this file and the stack's file automatically when working inside a stack directory.
## Project overview
Pulumi (TypeScript) IaC for a Proxmox-based k3s homelab. Independent Pulumi projects ("stacks"), each with its own `Pulumi.yaml`/`package.json`, deployed in order and linked via `pulumi.StackReference`:
| # | Directory | Pulumi stack | Purpose |
| --- | --- | --- | --- |
| 1 | `01-proxmox-infra` | `proxmox-infra` | Provisions k3s VMs + DHCP on Proxmox/pfSense |
| 2 | `02-k8s-bootstrap` | `k8s-bootstrap` | Installs k3s on the VMs over SSH |
| 3 | `03-k8s-infra` | `k8s-infra` | Cluster infra: storage, cert-manager, kube-vip |
| 4 | `04-k8s-apps` | `k8s-apps` | Application workloads (e.g. heimdall) |
| 5 | `05-monitoring` | `monitoring` | kube-prometheus-stack (Prometheus + Grafana) |
All stacks use the Pulumi stack name `dev`.
## Deployment order & StackReferences
```
proxmox-infra → k8s-bootstrap → k8s-infra
↘ k8s-apps → monitoring
```
- `k8s-bootstrap` reads VM IDs, Proxmox credentials, and the SSH private key from `proxmox-infra` via StackReference.
- `k8s-infra`, `k8s-apps`, and `monitoring` all read `kubeconfig` from `k8s-bootstrap` via StackReference (`requireOutput("kubeconfig")`) — never set `kubeconfig` as Pulumi config in these stacks.
- `monitoring` additionally reads `domain` from `k8s-apps` via StackReference.
- StackReference format: `${pulumi.getOrganization()}/<stack-name>/dev`.
A stack's outputs must exist (i.e. it must have been deployed) before any downstream stack referencing it will succeed.
## Shared conventions
- **TypeScript**: `strict: true`, `target: es2024`, `module`/`moduleResolution: nodenext`, `noImplicitReturns`, `noFallthroughCasesInSwitch` — functions need explicit return types where TS can't infer them.
- **Secrets**: read via `config.requireSecret()`, never via environment variables or hardcoded values.
- **`Pulumi.dev.yaml`**: gitignored (contains the encryption salt) — never delete it or secrets become unrecoverable. Encrypted with `PULUMI_CONFIG_PASSPHRASE`.
- **Backend**: self-hosted Postgres state backend, set via `PULUMI_BACKEND_URL`.
- Don't add a co-author when committing to git.
## Common commands (run from a stack directory)
```bash
npm install
pulumi preview
pulumi up --yes
pulumi destroy
pulumi stack output
pulumi config
```
Requires `PULUMI_BACKEND_URL` and `PULUMI_CONFIG_PASSPHRASE` in the environment (or `pulumi login`).
## CI/CD (Gitea Actions)
One workflow per stack: `.gitea/workflows/0N-deploy-<stack>.yaml`, scoped to changes under that stack's directory.
- **Pull request → `main`**: `pulumi preview` only.
- `01`/`02` (VM provisioning / cluster bootstrap — riskier to automate): deploy only via manual `workflow_dispatch`.
- `03``05`: deploy on push to `main` *or* `workflow_dispatch``pulumi refresh` then `pulumi up`.
- Each workflow restores `Pulumi.dev.yaml` from a base64-encoded Gitea secret (`<STACK>_PULUMI_DEV_YAML`). After changing local config, re-encode and update the secret:
```bash
base64 -w 0 0N-<stack>/Pulumi.dev.yaml
```

# Homelab Infrastructure as Code # Homelab Infrastructure as Code
A Pulumi-based IaC template for managing a Proxmox homelab. The goal is to replace manual GUI configuration and ad-hoc YAML stacks with version-controlled, reproducible infrastructure — a highly available k3s cluster across multiple Proxmox nodes, bootstrapped and configured end-to-end from code. A Pulumi-based IaC project for a Proxmox homelab: a highly-available k3s cluster, its cluster-level infrastructure, and the applications running on top of it — all provisioned and configured from code.
This repo is intentionally abstract: credentials are never hardcoded, making it easy to fork and adapt as a template for your own homelab. This repo is intentionally abstract: credentials are never hardcoded, making it easy to fork and adapt as a template for your own homelab.

The three stacks are deployed in order and linked via Pulumi StackReferences — outputs from one stack flow automatically into the next. ## Stacks
Stacks are deployed in order and linked via `pulumi.StackReference` — outputs from one stack flow automatically into the next, so a stack must be deployed before anything depending on it will work.

### Stack 1: `proxmox-infra` ### 1. proxmox-infra
Provisions a 5-node k3s cluster spread across two Proxmox hosts: Provisions a 5-node k3s cluster across two Proxmox hosts, each VM a clone of an Ubuntu Noble (24.04) cloud-image template:
| VM name | Role | Proxmox node | | VM | Role |
| ------------ | ------ | ------------ | | --- | --- |
| k3s-master-1 | master | pve | | k3s-master-1 | master |
| k3s-master-2 | master | pve | | k3s-master-2 | master |
| k3s-worker-1 | worker | pve | | k3s-worker-1 | worker |
| k3s-master-3 | master | pve-bckp | | k3s-master-3 | master |
| k3s-worker-2 | worker | pve-bckp | | k3s-worker-2 | worker |
Each VM is a full clone of an Ubuntu Noble (24.04) cloud-image template. Cloud-init injects the hostname, user credentials, and SSH keys at boot. An ED25519 SSH keypair is generated once and stored in Pulumi state — the public key goes into every VM, the private key is exported as a stack output for `k8s-bootstrap` to consume via StackReference. It also generates an ED25519 SSH keypair (stored in Pulumi state, public key injected via cloud-init) and registers each VM's MAC address as a DHCPv4 static mapping in pfSense.
Each VM's MAC address is registered as a DHCPv4 static mapping in pfSense so nodes always receive their designated IPs. **Providers:** `@muhlba91/pulumi-proxmoxve`, `@pulumi/pfsense` (locally bundled), `@pulumi/tls`
**Providers:** `@muhlba91/pulumi-proxmoxve` v8.x, `@pulumi/pfsense` (locally bundled), `@pulumi/tls` ### 2. k8s-bootstrap
**Exports:** `vmIds`, `ciRunnerPrivateKey`, `pve1Endpoint`, `pve1ApiToken`, `pve2Endpoint`, `pve2ApiToken`, `master1Ip``worker2Ip` Starts the VMs via the Proxmox API and installs k3s over SSH: `k3s-master-1` initializes the cluster (`--cluster-init`, embedded etcd), `k3s-master-2`/`k3s-master-3` join as additional etcd nodes, and the two workers join as agents. Exports the cluster's `kubeconfig` as a secret for downstream stacks.
### Stack 2: `k8s-bootstrap` ### 3. k8s-infra
Installs k3s on the Proxmox VMs over SSH using `@pulumi/command`. Reads VM IDs, Proxmox credentials, and the SSH private key from `proxmox-infra` via StackReference — no manual key distribution needed. Cluster-level infrastructure via Helm and `@pulumi/kubernetes`:
Deployment sequence:
1. Start all 5 VMs via the Proxmox REST API
2. Wait for port 22 to open on each node
3. Install k3s on `k3s-master-1` with `--cluster-init` (embedded etcd)
4. Join `k3s-master-2` and `k3s-master-3` as additional etcd nodes
5. Join `k3s-worker-1` and `k3s-worker-2` as agent nodes
6. Read `/etc/rancher/k3s/k3s.yaml` from master-1, patch the server URL, export as a secret stack output
**Exports:** `kubeconfig` (secret)
### Stack 3: `k8s-infra`
Deploys cluster-level infrastructure via Helm and the `@pulumi/kubernetes` provider. Reads `kubeconfig` from `k8s-bootstrap` via StackReference.

## Getting started ## Getting started
Deploy the stacks **in order**. Each stack must be fully deployed before the next one runs. Deploy stacks **in order** — each must be fully `pulumi up`'d before the next stack's `StackReference` resolves. Set the shared backend env vars once per shell:
### Stack 1 — `proxmox-infra`
```bash
cd proxmox-infra
npm install # also compiles the bundled pfSense SDK
pulumi stack init dev
```
Set secrets:
```bash
# Proxmox API credentials
pulumi config set --secret pve1Endpoint https://<proxmox-host-1>:8006
pulumi config set --secret pve1ApiToken <user>@pam!<token-id>=<uuid>
pulumi config set --secret pve2Endpoint https://<proxmox-host-2>:8006
pulumi config set --secret pve2ApiToken <user>@pam!<token-id>=<uuid>
# VM credentials
pulumi config set --secret k3sVmPassword <vm-password>
pulumi config set --secret sshPvePublicKey "ssh-ed25519 AAAA..."
# pfSense credentials (used for DHCPv4 static mappings)
pulumi config set --secret pfSenseUrl https://<pfsense-host>
pulumi config set --secret pfSenseUser <admin-username>
pulumi config set --secret pfSensePassword <admin-password>
# Static IP addresses assigned to each k3s node
pulumi config set --secret master1Ip <ip-for-k3s-master-1>
pulumi config set --secret master2Ip <ip-for-k3s-master-2>
pulumi config set --secret worker1Ip <ip-for-k3s-worker-1>
pulumi config set --secret master3Ip <ip-for-k3s-master-3>
pulumi config set --secret worker2Ip <ip-for-k3s-worker-2>
```
Deploy:
```bash ```bash
export PULUMI_BACKEND_URL=postgresql://<user>:<pass>@<host>/<db> export PULUMI_BACKEND_URL=postgresql://<user>:<pass>@<host>/<db>
export PULUMI_CONFIG_PASSPHRASE=<your-passphrase> export PULUMI_CONFIG_PASSPHRASE=<your-passphrase>
pulumi preview # inspect before touching anything
pulumi up --yes
``` ```
### Stack 2 — `k8s-bootstrap` Then for each stack, in order:
```bash ```bash
cd ../k8s-bootstrap cd 0N-<stack-dir>
npm install npm install
pulumi stack init dev pulumi stack init dev
pulumi config set ... # required keys and secrets
pulumi config set --secret k3sToken "$(openssl rand -hex 32)"
```
Node IPs and Proxmox credentials are read automatically from `proxmox-infra` outputs via StackReference — do not set them here.
```bash
pulumi up --yes pulumi up --yes
``` ```
### Stack 3 — `k8s-infra` Stack-specific notes:
**TrueNAS one-time setup** (before deploying this stack): 1. **proxmox-infra** — set Proxmox API tokens, pfSense credentials, VM credentials/SSH public key, and a static IP per node.
2. **k8s-bootstrap** — set `k3sToken` (e.g. `openssl rand -hex 32`) and a static IP per node. Proxmox credentials and the SSH key come automatically from `proxmox-infra`.
1. Create dataset `tank/k8s` 3. **k8s-infra** — before deploying, create an NFS dataset/share on TrueNAS (POSIX ACLs, `root`/`root` maproot, restricted to your k3s nodes). Set the TrueNAS, Cloudflare, and `kubeVipAddress`/`kubeVipInterface` config.
2. Add an NFS share for that dataset 4. **k8s-apps** — set `domain`, the base domain used for ingress hostnames.
5. **monitoring** — set `grafanaAdminPassword`.
- Acl Type: Set this to POSIX (or generic Unix permissions) rather than SMB/NFSv4 ACLs if you are on TrueNAS SCALE, as Kubernetes handles basic Unix permissions natively.
- Maproot User / Maproot Group: Set this to root and root
- Allowed Hosts/Networks: Restrict this share specifically to the IP addresses or the CIDR block of your Proxmox K3s nodes (e.g., 192.168.1.50)
3. In Network → Allowed Networks, permit your LAN subnet (e.g. `192.168.1.0/24`)
```bash
cd ../k8s-infra
npm install
pulumi stack init dev
# kubeconfig from k8s-bootstrap
KUBECONFIG=$(cd ../k8s-bootstrap && pulumi stack output kubeconfig --show-secrets)
pulumi config set --secret kubeconfig "$KUBECONFIG"
# TrueNAS NFS
pulumi config set --secret truenasHost <truenas-ip>
pulumi config set --secret truenasNfsPath /mnt/tank/k8s
# cert-manager + Cloudflare DNS-01
pulumi config set --secret cloudflareApiToken <cf-token>
pulumi config set --secret letsencryptEmail <your-email>
pulumi up --yes
```
## CI/CD (Gitea Actions) ## CI/CD (Gitea Actions)
One workflow per stack under `.gitea/workflows/`. Each triggers on changes to its own stack directory. One workflow per stack, `.gitea/workflows/0N-deploy-<stack>.yaml`, scoped to changes under that stack's directory.
| Event | Action | | Trigger | Stacks | Action |
| --------------------- | ------------------------------ | | --- | --- | --- |
| Pull request`main` | `pulumi preview` (read-only) | | PR`main` | all | `pulumi preview` (read-only) |
| Push to `main` | `pulumi refresh` + `pulumi up` | | Push to `main` | 0305 | `pulumi refresh` + `pulumi up` |
| Manual trigger | `pulumi refresh` + `pulumi up` | | Manual dispatch | all | `pulumi refresh` + `pulumi up` |
### Required Gitea secrets Stacks 01/02 (VM provisioning, cluster bootstrap) deploy **only** via manual dispatch — they're riskier to automate.
Configure under **Settings → Actions → Secrets**: ### Required secrets
| Secret | Used by | Description | | Secret | Used by |
| ------------------------------- | --------------------------- | ---------------------------------------------- | | --- | --- |
| `PULUMI_BACKEND_URL` | all workflows | PostgreSQL connection string for state backend | | `PULUMI_BACKEND_URL`, `PULUMI_CONFIG_PASSPHRASE` | all workflows |
| `PULUMI_CONFIG_PASSPHRASE` | all workflows | Passphrase to decrypt secrets | | `PROXMOX_INFRA_PULUMI_DEV_YAML` | 01-deploy-proxmox-infra |
| `PROXMOX_INFRA_PULUMI_DEV_YAML` | `deploy-proxmox-infra.yaml` | Base64-encoded `proxmox-infra/Pulumi.dev.yaml` | | `K8S_BOOTSTRAP_PULUMI_DEV_YAML` | 02-deploy-k8s-bootstrap |
| `K8S_BOOTSTRAP_PULUMI_DEV_YAML` | `deploy-k8s-bootstrap.yaml` | Base64-encoded `k8s-bootstrap/Pulumi.dev.yaml` | | `K8S_INFRA_PULUMI_DEV_YAML` | 03-deploy-k8s-infra |

| `MONITORING_PULUMI_DEV_YAML` | 05-deploy-monitoring |
`Pulumi.dev.yaml` files are gitignored (they contain your encryption salt). Whenever one changes, re-encode and paste into the corresponding Gitea secret: Each `<STACK>_PULUMI_DEV_YAML` secret is a base64-encoded copy of that stack's gitignored `Pulumi.dev.yaml`. After changing local config, re-encode and update the secret:
```bash ```bash
base64 -w 0 proxmox-infra/Pulumi.dev.yaml base64 -w 0 0N-<stack>/Pulumi.dev.yaml
base64 -w 0 k8s-bootstrap/Pulumi.dev.yaml
base64 -w 0 k8s-infra/Pulumi.dev.yaml
``` ```
## Adapting this as a template ## Using this as a template
1. Fork or copy the repo 1. Fork or copy the repo
2. Update Proxmox node names (`pve`, `pve-bckp`) and datastore IDs in `proxmox-infra/index.ts` 2. Update Proxmox node names/datastores and the `nodeConfigs` array in `01-proxmox-infra/index.ts` for your VM topology
3. Add or remove VMs from the `nodeConfigs` array 3. Set your own config/secrets per stack with `pulumi config set [--secret]` — see each stack's `CLAUDE.md` for the full list of required keys
4. Set your own secrets with `pulumi config set --secret` 4. Point the CI/CD workflows at your own Gitea/GitOps instance and update the secrets above
5. Point the CI/CD workflows at your own Gitea instance
