[ci skip] refactor claude files: compact CLAUDE.md, clean memory, remove generic agents
CLAUDE.md: 260→72 lines. Moved detailed patterns (NFS, iSCSI, Kyverno tables, anti-AI, node rebuild) to .claude/reference/patterns.md. Kept: critical rules, quick patterns, key commands, tier overview, prefs. Memory: CLAUDE.md is now single source of truth. Auto-memory reduced to scratch pad (67→25 lines, 5→1 files). MetaClaw DB cleaned from 40→16 entries (removed all infra-specific duplicates, kept cross-project prefs). Agents: removed generic devops-engineer (885L) and fullstack-developer (234L). Kept custom cluster-health-checker (48L).

# Infrastructure Repository Knowledge
|
||||
|
||||
## Instructions for Claude
|
||||
- **When the user says "remember" something**: Always update this file (`.claude/CLAUDE.md`) with the information so it persists across sessions
|
||||
- **When discovering new patterns or versions**: Add them to the appropriate section below
|
||||
- **After every significant change**: Proactively update this file to reflect what changed — new services, config changes, version bumps, new patterns, etc.
|
||||
- **After updating any `.claude/` files**: Always commit them immediately (`git add .claude/ && git commit -m "[ci skip] update claude knowledge"`)
|
||||
- **Skills available**: Check `.claude/skills/` directory for specialized workflows (e.g., `setup-project` for deploying new services)
|
||||
- **Reference data**: Check `.claude/reference/` for inventory tables, API patterns, and current state snapshots
|
||||
- **CRITICAL: All infrastructure changes must go through Terraform/Terragrunt**. NEVER modify cluster resources directly (kubectl apply/edit/patch, helm install, docker run). Use `kubectl` only for read-only operations and ephemeral debugging.
|
||||
- **CRITICAL: NEVER put sensitive data** (API keys, passwords, tokens, credentials) into committed files unless encrypted via git-crypt. Secrets belong in `terraform.tfvars` or `secrets/` directory.
|
||||
- **CRITICAL: NEVER commit secrets** — triple-check before every commit. Zero exceptions.
|
||||
- **CRITICAL: NEVER restart NFS** (`service nfsd restart` or equivalent on TrueNAS). This is destructive — it causes mount failures across all pods using NFS volumes cluster-wide. If NFS exports aren't taking effect, re-run `nfs_exports.sh` or wait; never restart the NFS service.
|
||||
- **New services MUST have CI/CD** (Woodpecker CI pipeline) and **monitoring** (Prometheus alerts and/or Uptime Kuma).
|
||||
## Instructions
|
||||
- **"remember X"**: Update this file, commit with `[ci skip]`
|
||||
- **Skills**: `.claude/skills/` (7 active workflows). Archived runbooks in `.claude/skills/archived/`
|
||||
- **Reference**: `.claude/reference/` — patterns.md (detailed procedures), service-catalog.md, proxmox-inventory.md, github-api.md, authentik-state.md
|
||||
- **Agents**: `.claude/agents/` — `cluster-health-checker` (haiku, autonomous health checks)
|
||||
|
||||
## Execution Environment
|
||||
- **Terraform/Terragrunt**: Always run locally: `cd stacks/<service> && terragrunt apply --non-interactive`
|
||||
## Critical Rules
|
||||
- **ALL changes through Terraform/Terragrunt** — never `kubectl apply/edit/patch` directly
|
||||
- **NEVER put secrets in committed files** — use `terraform.tfvars` or `secrets/` (git-crypt)
|
||||
- **NEVER restart NFS on TrueNAS** — causes cluster-wide mount failures
|
||||
- **NEVER commit secrets** — triple-check every commit
|
||||
- **New services need CI/CD** (Woodpecker) and **monitoring** (Prometheus/Uptime Kuma)
|
||||
- **ALWAYS `[ci skip]`** in commit messages when already applied locally
|
||||
- **Ask before pushing** to git. Commit specific files, not `git add -A`
|
||||
|
||||
## Execution
|
||||
- **Terragrunt**: `cd stacks/<service> && terragrunt apply --non-interactive`
|
||||
- **kubectl**: `kubectl --kubeconfig $(pwd)/config`
|
||||
- **GitHub API**: Use `curl` with tokens from tfvars (see `.claude/reference/github-api.md`). `gh` CLI is blocked by sandbox.
|
||||
|
||||
---
|
||||
- **Health check**: `bash scripts/cluster_healthcheck.sh --quiet`
|
||||
- **Plan all**: `cd stacks && terragrunt run --all --non-interactive -- plan`
|
||||
- **GitHub API**: `curl` with tokens from tfvars (`gh` CLI blocked by sandbox)
|
||||
|
||||
## Overview
|
||||
Terragrunt-based infrastructure repository managing a home Kubernetes cluster on Proxmox VMs, with per-service state isolation. Each service has its own Terragrunt stack under `stacks/`. Uses git-crypt for secrets encryption.
|
||||
Terragrunt-based homelab managing K8s cluster on Proxmox. Per-service stacks under `stacks/`. Git-crypt for secrets.
|
||||
- **Public domain**: `viktorbarzin.me` (Cloudflare) | **Internal**: `viktorbarzin.lan` (Technitium DNS)
|
||||
- **Cluster**: 5 nodes (master + node1-4, v1.34.2), GPU on node1 (Tesla T4)
|
||||
- **CI/CD**: Woodpecker CI — pushes to master auto-apply platform stack
|
||||
|
||||
## Key File Paths
|
||||
- `terraform.tfvars` — All secrets, DNS, Cloudflare config, WireGuard peers (git-crypt encrypted)
|
||||
- `terragrunt.hcl` — Root config (providers, backend, variable loading)
|
||||
- `stacks/<service>/` — Individual service stacks (`terragrunt.hcl` + `main.tf`)
|
||||
- `stacks/platform/` — Core infrastructure (~22 services in `modules/` subdir)
|
||||
- `stacks/infra/` — Proxmox VM resources
|
||||
- `modules/kubernetes/ingress_factory/`, `setup_tls_secret/` — Shared utility modules
|
||||
- `secrets/` — git-crypt encrypted TLS certs and keys
|
||||
## Key Paths
|
||||
- `terraform.tfvars` — secrets, DNS, Cloudflare (git-crypt)
|
||||
- `stacks/<service>/` — individual stacks | `stacks/platform/modules/` — core infra (~22 modules)
|
||||
- `modules/kubernetes/ingress_factory/`, `nfs_volume/`, `setup_tls_secret/` — shared modules
|
||||
|
||||
## Domains
|
||||
- **Public**: `viktorbarzin.me` (Cloudflare-managed)
|
||||
- **Internal**: `viktorbarzin.lan` (Technitium DNS)
|
||||
## Quick Patterns
|
||||
- **NFS volumes**: Use `nfs_volume` module (see `reference/patterns.md`). StorageClass: `nfs-truenas`. Never use inline `nfs {}` blocks.
|
||||
- **iSCSI (databases)**: StorageClass `iscsi-truenas` (democratic-csi). Used by PostgreSQL, MySQL.
|
||||
- **SMTP**: `var.mail_host` port 587 STARTTLS. NOT `mailserver.mailserver.svc.cluster.local` (cert mismatch).
|
||||
- **New service**: Use `setup-project` skill. Quick: create stack → add DNS in tfvars → apply platform → apply service.
|
||||
- **Ingress**: `ingress_factory` module. Auth: `protected = true`. Anti-AI: on by default.
|
||||
|
||||
## Key Patterns
|
||||
|
||||
### NFS Volume Pattern
|
||||
**Use the `nfs_volume` shared module** for all NFS volumes. This creates CSI-backed PV/PVC with soft mount options (`soft,timeo=30,retrans=3`) — no stale mount hangs:
|
||||
```hcl
|
||||
module "nfs_data" {
|
||||
source = "../../modules/kubernetes/nfs_volume" # or ../../../ for sub-stacks
|
||||
name = "<service>-data" # Must be globally unique (PV is cluster-scoped)
|
||||
namespace = kubernetes_namespace.<service>.metadata[0].name
|
||||
nfs_server = var.nfs_server
|
||||
nfs_path = "/mnt/main/<service>"
|
||||
}
|
||||
|
||||
# In pod spec:
|
||||
volume {
|
||||
name = "data"
|
||||
persistent_volume_claim {
|
||||
claim_name = module.nfs_data.claim_name
|
||||
}
|
||||
}
|
||||
```
|
||||
For platform modules, use `source = "../../../../modules/kubernetes/nfs_volume"`.
|
||||
**StorageClass**: `nfs-truenas` (deployed via `stacks/platform/modules/nfs-csi/`).
|
||||
**DO NOT use inline `nfs {}` blocks** — they mount with `hard,timeo=600` defaults which hang forever on stale mounts.
|
||||
|
||||
### iSCSI Storage for Databases
|
||||
**StorageClass**: `iscsi-truenas` (deployed via `stacks/platform/modules/iscsi-csi/` using democratic-csi).
|
||||
- Used by: PostgreSQL (CNPG), MySQL (InnoDB Cluster), Redis, Prometheus, Loki — any pod, any node, same data
|
||||
- Driver: `freenas-iscsi` (SSH-based, NOT `freenas-api-iscsi` which is TrueNAS SCALE only)
|
||||
- ZFS datasets: `main/iscsi` (zvols), `main/iscsi-snaps` (snapshots)
|
||||
- All K8s nodes have `open-iscsi` + `iscsid` running
|
||||
|
||||
### Adding NFS Exports
|
||||
1. **Create the directory on TrueNAS first**: `ssh root@10.0.10.15 "mkdir -p /mnt/main/<service> && chmod 777 /mnt/main/<service>"`
|
||||
2. Edit `secrets/nfs_directories.txt` — add path, keep sorted
|
||||
3. Run `secrets/nfs_exports.sh` from `secrets/` to update TrueNAS
|
||||
4. **Note**: If any path in `nfs_directories.txt` doesn't exist on TrueNAS, the API rejects the entire update and no paths are added. Fix missing dirs first.
|
||||
|
||||
### Factory Pattern (multi-user services)
|
||||
Structure: `stacks/<service>/main.tf` + `factory/main.tf`. Examples: `actualbudget`, `freedify`.
|
||||
To add a user: export NFS share, add Cloudflare route in tfvars, add module block calling factory.
|
||||
|
||||
### SMTP/Email
|
||||
- **Use**: `var.mail_host` (defaults to `mail.viktorbarzin.me`) port 587 (STARTTLS). **NOT** `mailserver.mailserver.svc.cluster.local` (TLS cert mismatch).
|
||||
- **Credentials**: `mailserver_accounts` in tfvars. Common: `info@viktorbarzin.me`
|
||||
|
||||
### Anti-AI Scraping (5-Layer Defense)
|
||||
All services have `anti_ai_scraping = true` by default in `ingress_factory`. Layers:
|
||||
1. **Bot blocking** (`traefik-ai-bot-block`): ForwardAuth → poison-fountain `/auth`. Returns 403 for GPTBot, ClaudeBot, CCBot, etc.
|
||||
2. **X-Robots-Tag** (`traefik-anti-ai-headers`): Adds `noai, noimageai`
|
||||
3. **Trap links** (`traefik-anti-ai-trap-links`): rewrite-body injects hidden links before `</body>` to `poison.viktorbarzin.me/article/*`
|
||||
4. **Tarpit**: `/article/*` drip-feeds at ~100 bytes/sec
|
||||
5. **Poison content**: 50 cached docs (CronJob every 6h, `--http1.1` required)
|
||||
|
||||
Key files: `stacks/poison-fountain/`, `stacks/platform/modules/traefik/middleware.tf`, `modules/kubernetes/ingress_factory/main.tf`
|
||||
Disable per-service: `anti_ai_scraping = false` in ingress_factory call.
|
||||
|
||||
### Terragrunt Architecture
|
||||
- Root `terragrunt.hcl` provides DRY provider, backend, variable loading, and shared `tiers` locals (via `generate "tiers"` block)
|
||||
- Each stack: `stacks/<service>/main.tf` with resources inline, state at `state/stacks/<service>/terraform.tfstate`
|
||||
- Platform modules: `stacks/platform/modules/<service>/`, shared modules: `modules/kubernetes/`
|
||||
- Dependencies via `dependency` block; variables from `terraform.tfvars` (unused silently ignored)
|
||||
- `secrets/` symlinks in stacks for TLS cert path resolution
|
||||
- Syntax: `--non-interactive` (not `--terragrunt-non-interactive`), `terragrunt run --all -- <command>` (not `run-all`)
|
||||
- **Tiers locals**: Auto-generated by Terragrunt into `tiers.tf` in every stack — do NOT add `locals { tiers = { ... } }` to stacks manually
|
||||
|
||||
### Adding a New Service
|
||||
Use the **`setup-project`** skill for the full workflow. Quick reference:
|
||||
1. Create `stacks/<service>/` with `terragrunt.hcl`, `main.tf`, `secrets` symlink
|
||||
2. Add Cloudflare DNS in `terraform.tfvars`
|
||||
3. Apply platform stack (for DNS): `cd stacks/platform && terragrunt apply --non-interactive`
|
||||
4. Apply service: `cd stacks/<service> && terragrunt apply --non-interactive`
|
||||
|
||||
### Shared Infrastructure Variables
|
||||
All stacks use variables from `terraform.tfvars` for shared service endpoints (auto-loaded by Terragrunt). **Never hardcode these values**:
|
||||
- `var.nfs_server` — NFS server IP (10.0.10.15)
|
||||
- `var.redis_host` — Redis hostname (redis.redis.svc.cluster.local)
|
||||
- `var.postgresql_host` — PostgreSQL hostname (postgresql.dbaas.svc.cluster.local)
|
||||
- `var.mysql_host` — MySQL hostname (mysql.dbaas.svc.cluster.local)
|
||||
- `var.ollama_host` — Ollama hostname (ollama.ollama.svc.cluster.local)
|
||||
- `var.mail_host` — Mail server hostname (mail.viktorbarzin.me)
|
||||
|
||||
For standalone stacks: add `variable "nfs_server" { type = string }` (etc.) to `main.tf`.
|
||||
For platform submodules: add the variable AND pass it through in `stacks/platform/main.tf` module block.
|
||||
|
||||
## Useful Commands
|
||||
```bash
|
||||
bash scripts/cluster_healthcheck.sh # Cluster health (24 checks)
|
||||
bash scripts/cluster_healthcheck.sh --quiet # Only WARN/FAIL
|
||||
cd stacks/<service> && terragrunt apply --non-interactive # Apply single stack
|
||||
cd stacks && terragrunt run --all --non-interactive -- plan # Plan all
|
||||
terraform fmt -recursive # Format all
|
||||
```
|
||||
|
||||
## CI/CD
|
||||
- Woodpecker CI (`.woodpecker/`): pushes apply `platform` stack, hosted at `https://ci.viktorbarzin.me`
|
||||
- TLS renewal pipeline: cron-triggered `renew2.sh` (certbot + Cloudflare DNS)
|
||||
- **ALWAYS add `[ci skip]`** to commit messages when you've already applied locally
|
||||
- **After committing, run `git push origin master`** to sync
|
||||
## Shared Variables (never hardcode)
|
||||
`var.nfs_server` (10.0.10.15), `var.redis_host`, `var.postgresql_host`, `var.mysql_host`, `var.ollama_host`, `var.mail_host`
|
||||
|
||||
## Infrastructure
|
||||
- Proxmox hypervisor (192.168.1.127) — see `.claude/reference/proxmox-inventory.md` for full VM table
|
||||
- Kubernetes cluster: 5 nodes (k8s-master + k8s-node1-4, v1.34.2), GPU on node1 (Tesla T4)
|
||||
- Docker registry pull-through cache at `10.0.20.10` — only docker.io (port 5000) and ghcr.io (port 5010) are active. quay.io/registry.k8s.io/reg.kyverno.io caches disabled (caused corrupted images).
|
||||
- GPU workloads need: `node_selector = { "gpu": "true" }` + `toleration { key = "nvidia.com/gpu", value = "true", effect = "NoSchedule" }`
|
||||
|
||||
### Node Rebuild Procedure
|
||||
1. **Drain the node** (if reachable): `kubectl drain k8s-nodeX --ignore-daemonsets --delete-emptydir-data`
|
||||
2. **Delete from K8s**: `kubectl delete node k8s-nodeX`
|
||||
3. **Destroy VM** (or remove from `stacks/infra/main.tf` and apply)
|
||||
4. **Ensure K8s template exists**: `ubuntu-2404-cloudinit-k8s-template` (VMID 2000). If not, apply `stacks/infra/`.
|
||||
5. **Get join command**: `ssh wizard@10.0.20.100 'sudo kubeadm token create --print-join-command'`
|
||||
6. **Update `k8s_join_command`** in `terraform.tfvars`
|
||||
7. **Create VM**: Add to `stacks/infra/main.tf` and apply
|
||||
8. **Wait for cloud-init** — VM auto-joins cluster
|
||||
9. **GPU node (k8s-node1) only**: Apply platform stack to re-apply GPU label/taint
|
||||
|
||||
**Note**: kubeadm tokens expire after 24h. Generate fresh just before creating the VM.
|
||||
|
||||
## Git Operations
|
||||
- **Git is slow** — commands can take 30+ seconds. Use `GIT_OPTIONAL_LOCKS=0` if git hangs.
|
||||
- Commit only specific files. **ALWAYS ask user before pushing**.
|
||||
- Proxmox (192.168.1.127) — see `reference/proxmox-inventory.md`
|
||||
- Pull-through cache at `10.0.20.10` — docker.io (:5000) and ghcr.io (:5010) only
|
||||
- GPU: `node_selector = { "gpu": "true" }` + `toleration { key = "nvidia.com/gpu", value = "true", effect = "NoSchedule" }`
|
||||
- Node rebuild: see `reference/patterns.md`
|
||||
|
||||
## Tier System
|
||||
- **0-core**: Critical infra (ingress, DNS, VPN, auth) | **1-cluster**: Redis, metrics, security | **2-gpu**: GPU workloads | **3-edge**: User-facing | **4-aux**: Optional
|
||||
- Tiers auto-generated into `tiers.tf` — available as `local.tiers.core`, `local.tiers.cluster`, etc.
|
||||
- Governance: Kyverno in `stacks/platform/modules/kyverno/` (resource-governance.tf, security-policies.tf)
|
||||
- Prometheus alerts: `stacks/platform/modules/monitoring/prometheus_chart_values.tpl`
|
||||
`0-core` (ingress, DNS, VPN, auth) | `1-cluster` (Redis, metrics) | `2-gpu` | `3-edge` (user-facing) | `4-aux` (optional)
|
||||
- Auto-generated into `tiers.tf` — use `local.tiers.core`, `local.tiers.cluster`, etc.
|
||||
- Kyverno governance: LimitRange defaults + ResourceQuota per namespace (see `reference/patterns.md`)
|
||||
- **OOMKilled?** → Container without explicit resources gets 256Mi (edge/aux). Set explicit `resources {}`.
|
||||
- **Won't schedule?** → Check `kubectl describe resourcequota tier-quota -n <ns>`
|
||||
- **Opt-out**: labels `resource-governance/custom-quota=true` and/or `resource-governance/custom-limitrange=true`
|
||||
|
||||
### Kyverno Resource Governance (CRITICAL for debugging container failures)
|
||||
|
||||
**LimitRange defaults** — Kyverno auto-generates a `tier-defaults` LimitRange in every namespace. Containers WITHOUT explicit `resources {}` get these injected:
|
||||
|
||||
| Tier | Default CPU | Default Mem | Request CPU | Request Mem | Max CPU | Max Mem |
|
||||
|------|-------------|-------------|-------------|-------------|---------|---------|
|
||||
| 0-core | 500m | 512Mi | 50m | 64Mi | 4 | 8Gi |
|
||||
| 1-cluster | 500m | 512Mi | 50m | 64Mi | 2 | 4Gi |
|
||||
| 2-gpu | 1 | 2Gi | 100m | 256Mi | 8 | 16Gi |
|
||||
| 3-edge | 250m | 256Mi | 25m | 64Mi | 2 | 4Gi |
|
||||
| 4-aux | 250m | 256Mi | 25m | 64Mi | 2 | 4Gi |
|
||||
| No tier | 250m | 256Mi | 25m | 64Mi | 1 | 2Gi |
|
||||
|
||||
**ResourceQuota** — auto-generated per namespace (opt-out: label `resource-governance/custom-quota=true`):
|
||||
|
||||
| Tier | req CPU | req Mem | lim CPU | lim Mem | Pods |
|
||||
|------|---------|--------|---------|---------|------|
|
||||
| 0-core | 8 | 8Gi | 32 | 64Gi | 100 |
|
||||
| 1-cluster | 4 | 4Gi | 16 | 32Gi | 30 |
|
||||
| 2-gpu | 8 | 8Gi | 48 | 96Gi | 40 |
|
||||
| 3-edge | 4 | 4Gi | 16 | 32Gi | 30 |
|
||||
| 4-aux | 2 | 2Gi | 8 | 16Gi | 20 |
|
||||
|
||||
Custom quota namespaces: `authentik` (16 req CPU/16Gi req mem/48 lim CPU/96Gi lim mem/50 pods), `monitoring` (opted out, no replacement), `nvidia` (opted out, no replacement), `nextcloud` (custom), `onlyoffice` (custom).
|
||||
|
||||
**LimitRange opt-out**: label `resource-governance/custom-limitrange=true` — skips Kyverno-generated LimitRange, requires a custom `kubernetes_limit_range` in the stack. Used by: `nextcloud` (max 16 CPU/8Gi), `onlyoffice` (max 8 CPU/8Gi).
|
||||
|
||||
**Other mutating policies**: `inject-priority-class-from-tier` (sets priorityClassName, **CREATE only**), `inject-ndots` (ndots:2 on all pods), `sync-tier-label-from-namespace`, `goldilocks-vpa-auto-mode` (sets VPA to `off` for ALL namespaces — Terraform owns container resources, Goldilocks is observe-only).
|
||||
|
||||
**Goldilocks VPA**: VPA is in `off` mode globally — it provides resource recommendations only via the Goldilocks dashboard, but never mutates pods. Terraform is the sole authority for container resources.
|
||||
|
||||
**Security policies** (ALL Audit mode, log-only): `deny-privileged-containers`, `deny-host-namespaces`, `restrict-sys-admin`, `require-trusted-registries`.
|
||||
|
||||
**Debugging container failures checklist**:
|
||||
1. **OOMKilled?** → Check `kubectl describe limitrange tier-defaults -n <ns>`. Containers without explicit resources get 256Mi limit in edge/aux tiers.
|
||||
2. **Won't schedule?** → Check `kubectl describe resourcequota tier-quota -n <ns>`. Namespace may be at capacity.
|
||||
3. **Evicted?** → aux-tier pods (priority 200K, Never preempt) are first evicted under pressure.
|
||||
4. **Unexpected limits?** → LimitRange injects defaults when `resources: {}` or no resources block exists. Always set explicit resources.
|
||||
5. **Need more?** → Set explicit `resources {}` on container (overrides LimitRange defaults) or add `resource-governance/custom-quota=true` label + `resource-governance/custom-limitrange=true` label with custom resources in the stack.
|
||||
6. **Pod patch failing with immutable spec?** → Kyverno `inject-priority-class-from-tier` was fixed to CREATE-only. If similar issues arise, check mutating webhooks with `kubectl get mutatingwebhookconfigurations`.

## MySQL InnoDB Cluster (dbaas namespace)
|
||||
- 3 instances on `iscsi-truenas`, anti-affinity excludes k8s-node2 (SIGBUS in init containers)
|
||||
- `mysql` service selector includes `mysql.oracle.com/cluster-role: PRIMARY`
|
||||
- GR bootstrap: `SET GLOBAL group_replication_bootstrap_group=ON; START GROUP_REPLICATION;`
|
||||
- Service users NOT managed by Terraform — recreate manually after cluster rebuild
|
||||
- `manualStartOnBoot: true` — GR doesn't auto-start, needs bootstrap after full restart
|
||||
|
||||

```
|
||||
|
||||
Your DevOps implementations should prioritize:
|
||||
1. **Infrastructure as Code** - Everything versioned and reproducible
|
||||
2. **Automated Testing** - Security, performance, and functional validation
|
||||
3. **Progressive Deployment** - Risk mitigation through staged rollouts
|
||||
4. **Comprehensive Monitoring** - Observability across all system layers
|
||||
5. **Security by Design** - Built-in security controls and compliance checks
|
||||
|
||||
Always include rollback procedures, disaster recovery plans, and comprehensive documentation for all automation workflows.

||||
|
||||
Begin every fullstack task by understanding the complete technology landscape.
|
||||
|
||||
Context acquisition query:
|
||||
```json
|
||||
{
|
||||
"requesting_agent": "fullstack-developer",
|
||||
"request_type": "get_fullstack_context",
|
||||
"payload": {
|
||||
"query": "Full-stack overview needed: database schemas, API architecture, frontend framework, auth system, deployment setup, and integration points."
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||

# Detailed Infrastructure Patterns
|
||||
|
||||
Reference file for patterns, procedures, and tables. Read on demand when the specific topic comes up.
|
||||
|
||||
## NFS Volume Pattern
|
||||
Use the `nfs_volume` shared module for all NFS volumes (CSI-backed, `soft,timeo=30,retrans=3`):
|
||||
```hcl
|
||||
module "nfs_data" {
|
||||
source = "../../modules/kubernetes/nfs_volume" # ../../../../ for platform modules, ../../../ for sub-stacks
|
||||
name = "<service>-data" # Must be globally unique (PV is cluster-scoped)
|
||||
namespace = kubernetes_namespace.<service>.metadata[0].name
|
||||
nfs_server = var.nfs_server
|
||||
nfs_path = "/mnt/main/<service>"
|
||||
}
|
||||
# In pod spec: persistent_volume_claim { claim_name = module.nfs_data.claim_name }
|
||||
```
|
||||
**DO NOT use inline `nfs {}` blocks** — they mount with `hard,timeo=600` defaults which hang forever.
|
||||
|
||||
## Adding NFS Exports
|
||||
1. Create dir on TrueNAS: `ssh root@10.0.10.15 "mkdir -p /mnt/main/<service> && chmod 777 /mnt/main/<service>"`
|
||||
2. Edit `secrets/nfs_directories.txt` — add path, keep sorted
|
||||
3. Run `secrets/nfs_exports.sh` from `secrets/`
|
||||
4. If any path doesn't exist on TrueNAS, the API rejects the entire update.
|
||||
|
||||
## iSCSI Storage (Databases)
|
||||
**StorageClass**: `iscsi-truenas` (democratic-csi, `freenas-iscsi` SSH driver — NOT `freenas-api-iscsi`).
|
||||
Used by: PostgreSQL (CNPG), MySQL (InnoDB Cluster). ZFS: `main/iscsi` (zvols), `main/iscsi-snaps`.
|
||||
All K8s nodes have `open-iscsi` + `iscsid` running.
|
||||
|
||||
## Anti-AI Scraping (5-Layer Defense)
|
||||
Default `anti_ai_scraping = true` in ingress_factory. Disable per-service: `anti_ai_scraping = false`.
|
||||
1. Bot blocking (ForwardAuth → poison-fountain) 2. X-Robots-Tag noai 3. Trap links before `</body>`
|
||||
4. Tarpit (~100 bytes/sec) 5. Poison content (CronJob every 6h, `--http1.1` required)
|
||||
Key files: `stacks/poison-fountain/`, `stacks/platform/modules/traefik/middleware.tf`
|
||||
|
||||
## Terragrunt Architecture
|
||||
- Root `terragrunt.hcl`: DRY providers, backend, variable loading, `generate "tiers"` block
|
||||
- Each stack: `stacks/<service>/main.tf`, state at `state/stacks/<service>/terraform.tfstate`
|
||||
- Platform modules: `stacks/platform/modules/<service>/`, shared: `modules/kubernetes/`
|
||||
- Syntax: `--non-interactive`, `terragrunt run --all -- <command>` (not `run-all`)
|
||||
- Tiers auto-generated into `tiers.tf` — never add `locals { tiers = {} }` manually
|
||||
|
||||
## Factory Pattern (Multi-User Services)
|
||||
Structure: `stacks/<service>/main.tf` + `factory/main.tf`. Examples: `actualbudget`, `freedify`.
|
||||
To add a user: export NFS share, add Cloudflare route in tfvars, add module block calling factory.
|
||||
|
||||
## Node Rebuild Procedure
|
||||
1. Drain: `kubectl drain k8s-nodeX --ignore-daemonsets --delete-emptydir-data`
|
||||
2. Delete: `kubectl delete node k8s-nodeX`
|
||||
3. Destroy VM (remove from `stacks/infra/main.tf`)
|
||||
4. Get fresh join command: `ssh wizard@10.0.20.100 'sudo kubeadm token create --print-join-command'` (tokens expire 24h)
|
||||
5. Update `k8s_join_command` in `terraform.tfvars`, add VM to `stacks/infra/main.tf`, apply
|
||||
6. GPU node (k8s-node1): apply platform stack to re-apply GPU label/taint
|
||||

||||
## Kyverno Resource Governance
|
||||
|
||||
### LimitRange Defaults (injected when no explicit `resources {}`)
|
||||
| Tier | Default Mem | Max Mem | Default CPU | Max CPU |
|
||||
|------|------------|---------|-------------|---------|
|
||||
| 0-core | 512Mi | 8Gi | 500m | 4 |
|
||||
| 1-cluster | 512Mi | 4Gi | 500m | 2 |
|
||||
| 2-gpu | 2Gi | 16Gi | 1 | 8 |
|
||||
| 3-edge / 4-aux | 256Mi | 4Gi | 250m | 2 |
|
||||
| No tier | 256Mi | 2Gi | 250m | 1 |
|
||||
|
||||
### ResourceQuota (opt-out: `resource-governance/custom-quota=true`)
|
||||
| Tier | lim CPU | lim Mem | Pods |
|
||||
|------|---------|---------|------|
|
||||
| 0-core | 32 | 64Gi | 100 |
|
||||
| 1-cluster | 16 | 32Gi | 30 |
|
||||
| 2-gpu | 48 | 96Gi | 40 |
|
||||
| 3-edge / 4-aux | 8-16 | 16-32Gi | 20-30 |
|
||||
|
||||
Custom quotas: authentik, monitoring (opted out), nvidia (opted out), nextcloud, onlyoffice.
|
||||
LimitRange opt-out: `resource-governance/custom-limitrange=true` + custom `kubernetes_limit_range` in stack.
|
||||
|
||||
### Other Policies
|
||||
- `inject-priority-class-from-tier` (CREATE only), `inject-ndots` (ndots:2), `sync-tier-label`
|
||||
- `goldilocks-vpa-auto-mode`: VPA `off` globally — Terraform owns resources, Goldilocks observe-only
|
||||
- Security policies ALL Audit mode: `deny-privileged-containers`, `deny-host-namespaces`, `restrict-sys-admin`, `require-trusted-registries`
|
||||
|
||||
### Debugging Container Failures
|
||||
1. **OOMKilled?** → `kubectl describe limitrange tier-defaults -n <ns>`. edge/aux default = 256Mi.
|
||||
2. **Won't schedule?** → `kubectl describe resourcequota tier-quota -n <ns>`.
|
||||
3. **Evicted?** → aux-tier pods (priority 200K, Never preempt) evicted first.
|
||||
4. **Unexpected limits?** → LimitRange injects defaults. Always set explicit resources.
|
||||
5. **Need more?** → Set explicit `resources {}` or add quota/limitrange opt-out labels.
|
||||
|
||||
## Authentik (Identity Provider)
|
||||
- **URL**: `https://authentik.viktorbarzin.me` | **API**: `/api/v3/` | **Token**: `authentik_api_token` in tfvars
|
||||
- 3 server + 3 worker + 3 PgBouncer + embedded outpost
|
||||
- Forward auth: `protected = true` in ingress_factory
|
||||
- OIDC for K8s: issuer `.../application/o/kubernetes/`, client `kubernetes` (public)
|
||||
- See archived skills for management tasks and OIDC gotchas
