# App deployment guidelines
|
||||
|
||||
This document summarizes current guidelines, requirements, common patterns, and standards that newly deployed apps should meet.
|
||||
|
||||
## Structure
|
||||
|
||||
Each app on cluster should be contained in its own kustomization living in subdirectory under [apps](/apps) and imported from main [apps kustomization](/apps/kustomization.yaml). Apps that provide infrastructural services belong to [infra](/infra). Few examples:
|
||||
|
||||
- **Open WebUI**: Web app, belongs in [apps/openwebui](/apps/openwebui/) together with its direct and unique dependencies eg. database
|
||||
- **llama-swap** (llama.cpp + whisper + stablediffusion): Inference server, service used by other deployments on cluster but does not manages cluster, belongs in [apps/llama](/apps/llama/)
|
||||
- **kokoro**: Text to speech inference server, also service used by other deployments, I consider it closely related to llama-swap, so due to arbitrary decision, keeping it together with llama-swap under [apps/llama](/apps/llama/)
|
||||
- **crawl4ai**: Web scraper, another service used only by other apps, belongs in [apps/crawl4ai](/apps/crawl4ai/)
|
||||
- **Gitea**: Code forge, despite being essential for overall architecture (holding cluster's code) is not a core cluster software, belongs in [apps/gitea](/apps/gitea/)
|
||||
- **Woodpecker**: Continous Integration system, belongs in [apps/woodpecker](/apps/woodpecker/)
|
||||
- **Cilium**: Kubernetes CNI, core cluster functionality, belongs in [infra/controllers/cilium.yaml](/infra/controllers/cilium.yaml)
|
||||
- **Nginx Ingress Controller**: Provides ingress kubernetes functionality, belongs in [infra/controllers/nginx-ingress.yaml](/infra/controllers/nginx-ingress.yaml)
|
||||
- **CloudNativePG**: Kubernetes PostgreSQL operator, belongs in [infra/controllers/cloudnative-pg.yaml](/infra/controllers/cloudnative-pg.yaml)
|
||||
- **OpenBao** Secret storage and Kubernetes operator, belongs in [infra/controllers/openbao.yaml](/infra/controllers/openbao.yaml)
|
||||
|
||||
Kustomizations are reconciled on `git push` by flux running on cluster, triggered by [Woodpecker job](/.woodpecker/flux-reconcile-source.yaml). App Kustomization should import all resources related to app in `kustomization.yaml`:
|
||||
|
||||
```yaml
|
||||
apiVersion: kustomize.config.k8s.io/v1beta1
|
||||
kind: Kustomization
|
||||
resources:
|
||||
- namespace.yaml
|
||||
- pvc.yaml
|
||||
- release.yaml
|
||||
```
|
||||
|
||||
## Namespace
|
||||
|
||||
Each app kustomization should have its own kubernetes namespace to contain all resources related to app in `namespace.yaml`:
|
||||
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: Namespace
|
||||
metadata:
|
||||
name: immich
|
||||
```
|
||||
|
||||
## Helm charts
|
||||
|
||||
If app is distributed via Helm chart, you can deploy it using flux HelmRepository and HelmRelease resources like in following example:
|
||||
|
||||
```yaml
|
||||
---
|
||||
apiVersion: source.toolkit.fluxcd.io/v1
|
||||
kind: HelmRepository
|
||||
metadata:
|
||||
name: secustor
|
||||
namespace: immich
|
||||
spec:
|
||||
interval: 24h
|
||||
url: https://secustor.dev/helm-charts
|
||||
---
|
||||
apiVersion: helm.toolkit.fluxcd.io/v2
|
||||
kind: HelmRelease
|
||||
metadata:
|
||||
name: immich
|
||||
namespace: immich
|
||||
spec:
|
||||
interval: 30m
|
||||
chart:
|
||||
spec:
|
||||
chart: immich
|
||||
version: 1.2.6
|
||||
sourceRef:
|
||||
kind: HelmRepository
|
||||
name: secustor
|
||||
values:
|
||||
<values>
|
||||
```
|
||||
|
||||
If the app does not have a helm repository, but helm chart is available in git repository directly in repository, you can make use of it using GitRepository flux source:
|
||||
|
||||
```yaml
|
||||
---
|
||||
apiVersion: source.toolkit.fluxcd.io/v1
|
||||
kind: GitRepository
|
||||
metadata:
|
||||
name: kaneo
|
||||
namespace: kaneo
|
||||
spec:
|
||||
interval: 24h
|
||||
url: https://github.com/usekaneo/kaneo.git
|
||||
ref:
|
||||
tag: v2.7.5
|
||||
ignore: |
|
||||
# exclude all
|
||||
/*
|
||||
# include charts directory
|
||||
!/charts/
|
||||
```
|
||||
|
||||
You can use third-party helm charts to deploy applications, consider this possibility if:
|
||||
|
||||
- There is no official helm chart for the application
|
||||
- The official helm chart is unmaintained
|
||||
- The official helm chart is using glaring bad practices
|
||||
- The official helm chart is missing configuration options for what we need
|
||||
|
||||
When deciding which helm chart to use, watch out for following things in particular:
|
||||
|
||||
- Development activity, stability, maturity
|
||||
- Whether the app deployed by chart is up to date - automated updates are large bonus
|
||||
- Unresolved / breaking issues
|
||||
- Configurability, can we configure things we need, disable undesired features
|
||||
|
||||
When configuring Helm chart, keep in mind:
|
||||
- Do not use bundled PVCs, bring our own one or at least configure chart to bind it to manually created `PersistentVolume` according to [Data / PVCs pattern](#data--pvcs-pattern)
|
||||
- Do not use bundled Postgres database unless the chart is using CloudNativePG's Cluster resource, bring our own one using [Postgres operator](#postgres-operator)
|
||||
- do not
|
||||
|
||||
## Bare Kubernetes deployments
|
||||
|
||||
If:
|
||||
|
||||
- the app is not packaged as a helm chart or
|
||||
- it would be simpler to deploy it without package (for example custom privileged pod with access to gpu) or
|
||||
- the app is so simple it doesn't make sense to make helm package it (for example, simple http proxy that alters headers or stateless single-binary app) or
|
||||
- for any other reason it would make more sense to skip helm
|
||||
|
||||
You can deploy app skipping helm chart and just create raw Kubernetes manifests like Deployment, StatefulSet and other supporting resources like ConfigMap, Service, Ingress directly.
|
||||
|
||||
## Data / PVCs pattern
|
||||
|
||||
Data are stored on local disk of node using OpenEBS LVM LocalPV. To create a persistent volume, use following example:
|
||||
|
||||
```yaml
|
||||
---
|
||||
apiVersion: local.openebs.io/v1alpha1
|
||||
kind: LVMVolume
|
||||
metadata:
|
||||
labels:
|
||||
kubernetes.io/nodename: anapistula-delrosalae
|
||||
name: immich-library-lvmhdd
|
||||
namespace: openebs
|
||||
spec:
|
||||
capacity: 150Gi
|
||||
ownerNodeID: anapistula-delrosalae
|
||||
shared: "yes"
|
||||
thinProvision: "no"
|
||||
vgPattern: ^openebs-hdd$
|
||||
volGroup: openebs-hdd
|
||||
---
|
||||
kind: PersistentVolume
|
||||
apiVersion: v1
|
||||
metadata:
|

```
|
||||
|
||||
Create LVMVolume and PersistentVolume resources manually and **do not** rely on automatic scheduling of PVCs because we want created LVM LVs on disk to have deterministic names and be reused if already exist on disk, which scheduler does not give us. There are two LVM storage classes:
|
||||
|
||||
- **hdd-lvmpv**, volume group: openebs-hdd, use for bulk data, like media library
|
||||
- **ssd-lvmpv**, volume group: openebs-ssd, use for small datasets that benefit from quick storage access like databases, state data etc.
|
||||
|
||||
When deciding the size of the volume, make minimal prediction, starting with 1GiB if you do not predict app to use much disk space.
|
||||
|
||||
## Vault secrets
|
||||
|
||||
There is OpenBao installed on cluster that manages access to secrets. The KV2 secret engine is mounted at `secret`, use it to store static secrets like API keys to external services, passwords and other entries you do not want to keep in plaintext in git repository.
|
||||
|
||||
To access the KV secrets on cluster, use Vault Secrets Operator installed on cluster, which provides `VaultStaticSecret` custom resource that syncs a path from OpenBao to Kubernetes `Secret` object.
|
||||
|
||||
```yaml
|
||||
---
|
||||
apiVersion: v1
|
||||
kind: ServiceAccount
|
||||
metadata:
|
||||
name: llama-proxy
|
||||
namespace: llama
|
||||
---
|
||||
apiVersion: secrets.hashicorp.com/v1beta1
|
||||
kind: VaultAuth
|
||||
metadata:
|
||||

|
||||
namespace: llama
|
||||
spec:
|
||||

||||

||||

|
||||

|
||||
---
|
||||
apiVersion: secrets.hashicorp.com/v1beta1
|
||||
kind: VaultStaticSecret
|
||||
metadata:
|
||||
name: llama-api-key
|
||||
namespace: llama
|
||||
spec:
|
||||
type: kv-v2
|
||||
|
||||
mount: secret
|
||||
path: ollama
|
||||
|
||||
destination:
|
||||
create: true
|
||||
name: llama-api-key
|
||||
type: Opaque
|
||||
transformation:
|
||||
excludeRaw: true
|
||||
|
||||
vaultAuthRef: llama
|
||||
```
|
||||
|
||||
To give access to specified secret for given k8s ServiceAccount, you need to create kubernetes auth role and policy. Create a kubernetes auth role named `llama-proxy`, by creating file `vault/kubernetes-auth-roles/llama-proxy.yaml`:
|
||||
|
||||
```yaml
|
||||
bound_service_account_names:
|
||||
- llama-proxy
|
||||
bound_service_account_namespaces:
|
||||
- llama
|
||||
token_policies:
|
||||
- ollama
|
||||
```
|
||||
|
||||
Create policy named `ollama` by creating file `vault/policy/ollama.hcl`:
|
||||
|
||||
```hcl
|
||||
path "secret/data/ollama" {
|
||||
capabilities = ["read"]
|
||||
}
|
||||
```
|
||||
|
||||
Once these files are created, ask operator to reconcile OpenBao configuration and create required secret.
|
||||
|
||||
## Postgres operator
|
||||
|
||||
There is CloudNativePG operator installed on cluster that manages databases of applications running on cluster. You can create Postgres database by creating `Cluster` resource:
|
||||
|
||||
```yaml
|
||||
---
|
||||
apiVersion: postgresql.cnpg.io/v1
|
||||
kind: Cluster
|
||||
metadata:
|
||||
name: kaneo-db
|
||||
namespace: kaneo
|
||||
spec:
|
||||
instances: 1
|
||||
|
||||
storage:
|
||||
pvcTemplate:
|
||||
storageClassName: ssd-lvmpv
|
||||
resources:
|
||||
requests:
|
||||
storage: 10Gi
|
||||
volumeName: kaneo-db-1
|
||||
|
||||
```
|
||||
|
||||
Create a `PersistentVolume` and `LVMVol` resources manually but **do not** create `PersistentVolumeClaim`, CloudNativePG will create one on its own referencing `PersistentVolume` specified in `volumeName`. Do not replicate the database, there is only one node in the cluster currently. The `Cluster` resource will automatically create secret, use it to configure app:
|
||||
|
||||
```
|
||||
Name: kaneo-db-app
|
||||
Namespace: kaneo
|
||||
Labels: app.kubernetes.io/managed-by=cloudnative-pg
|
||||

```
|
||||
|
||||
## LoadBalancers
|
||||
|
||||
You can expose installed app to the Internet using Cilium's LoadBalancer configured on cluster:
|
||||
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: Service
|
||||
metadata:
|
||||
name: teamspeak3
|
||||
namespace: ispeak3
|
||||
spec:
|
||||
selector:
|
||||
app: teamspeak3
|
||||
ports:
|
||||
- name: voice
|
||||
protocol: UDP
|
||||
port: 9987
|
||||
targetPort: 9987
|
||||
- name: filetransfer
|
||||
protocol: TCP
|
||||
port: 30033
|
||||
targetPort: 30033
|
||||
type: LoadBalancer
|
||||
externalTrafficPolicy: Local
|
||||
ipFamilyPolicy: PreferDualStack
|
||||
```
|
||||
|
||||
IPv6 will be directly reachable from the internet by its assigned address, for IPv4 currently you need to configure port forward on router in `ansible/roles/routeros/firewall.yml`, that step is not yet automated. The assigned internal IP will be known after manifests are applied on cluster. For this reason, there is no ExternalDNS configured yet, if you need a DNS name, ask the operator to configure DNS name for LoadBalancer. Assign names from lumpiasty.xyz subdomains (eg. kaneo.lumpiasty.xyz) unless explicitly requested. Do not use LoadBalancer for exposing HTTP applications, use Ingress instead.
|
||||
|
||||
## Ingress
|
||||
|
||||
You can expose HTTP applications using NGINX Ingress Controller:
|
||||
|
||||
```yaml
|
||||
---
|
||||
apiVersion: networking.k8s.io/v1
|
||||
kind: Ingress
|
||||
metadata:
|
||||
namespace: llama
|
||||

|
||||

|
||||

|
||||

|
||||

|
||||
nginx.ingress.kubernetes.io/proxy-read-timeout: 30m
|
||||
nginx.ingress.kubernetes.io/proxy-body-size: 8m
|
||||
spec:
|
||||
ingressClassName: nginx-ingress
|
||||
rules:
|
||||
- host: llama.lumpiasty.xyz
|
||||
http:
|
||||
paths:
|
||||
- backend:
|
||||
service:
|
||||
name: llama-proxy
|
||||
port:
|
||||

|
||||
path: /
|
||||
pathType: Prefix
|
||||
tls:
|
||||
- hosts:
|
||||
- llama.lumpiasty.xyz
|
||||
secretName: llama-ingress
|
||||
```
|
||||
|
||||
TLS certificates are automatically issued for subdomains of lumpiasty.xyz using cert-manager. DNS name assignment is not automatic yet, ask operator to create DNS name for ingress resources.
|
||||
|
||||
## Keeping app up to date
|
||||
|
||||
There is a Renovate job configured for this repository as [Woodpecker job](/.woodpecker/renovate.yaml) to keep applications up to date. Renovate automatically keeps track of:
|
||||
|
||||
- Docker images specified in Kubernetes manifests like Deployment, StatefulSet etc
|
||||
- HelmRelease versions
|
||||
- GitRepository tags
|
||||
|
||||
To make Renovate automatically update applications, always specify full versions of docker images or helm chart release. If you use ambigous tags, renovate will not have chance to update and the cluster will never download new image because this tag already existed on node. **Do not** use:
|
||||
|
||||
- latest (or its variants like stable, current, main, master current)
|
||||
- "Sliding" versions, like 1 or 1.2 that point at 1.2.1 currently and will change image it points at when version 1.2.2 is released
|
||||
|
||||
As a last resort if the application does not publish stable image tags, pin digest of image.
|
||||
|
||||
Renovate may require custom configuration if:
|
||||
|
||||
- App is using non-standard versioning schema
|
||||
|
||||
Example app versioned by date (unified-vulkan-2026-01-01), renovate.json:
|
||||
|
||||
```json
|
||||
{
|
||||
"matchDatasources": ["docker"],
|
||||
"matchPackageNames": ["ghcr.io/mostlygeek/llama-swap"],
|
||||
"versioning": "regex:^unified-vulkan-(?<major>\\d{4})-(?<minor>\\d{2})-(?<patch>\\d{2})$",
|
||||
"automerge": true,
|
||||
"automergeType": "pr",
|
||||
"platformAutomerge": true
|
||||
}
|
||||
```
|
||||
|
||||
- Docker image tag is specified in non-standard field that Renovate may not recognise automatically such as Helm values
|
||||
|
||||
Example app with non-standard image selected in helm values instead of image's default (which is latest in this chart):
|
||||
```yaml
|
||||
values:
|
||||
kaneo:
|
||||
image:
|
||||
tag: "2.7.3" # renovate: depName=ghcr.io/usekaneo/kaneo registryUrl=https://ghcr.io
|
||||
```
|
||||
|
||||
Renovate is configured so it automatically merges patch versions, other updates are created as pull requests to be manually reviewed and merged unless explicitly desired on per case basis.
|
||||
|
||||
## SSO / OIDC / Authentik
|
||||
|
||||
There is an Authentik running on cluster providing SSO for applications. Configure user-facing apps to utilize it correctly.
|
||||
|
||||
Authentik supports following protocols:
|
||||
|
||||
- OAuth2 / OpenID Connect
|
||||
- SAML
|
||||
- Radius
|
||||
- LDAP
|
||||
- SCIM
|
||||
|
||||
Currently, there is no Authentik configuration in code, ask operator to create application in the UI and save OAuth id and secret in OpenBao under `secret/authentik/<app>`. Authentik provides discovery URL for OAuth applications: `https://authentik.lumpiasty.xyz/application/o/<app slug>/.well-known/openid-configuration`.
|
||||
|
||||
Configure the app to disable guest access, built-in registration and automatically register unprivileged users with `user` role and privileged users with `admin` role as the app allows.
|
||||
|
||||
## Privileged apps
|
||||
|
||||
Some apps require direct access to devices, like GPU. There are no specific operators yet, apps that require access to GPU are simply launched as privileged pods, example:
|
||||
|
||||
```yaml
|
||||
---
|
||||
apiVersion: apps/v1
|
||||
kind: Deployment
|
||||
metadata:
|
||||

||||

||||

|
||||

|
||||

|
||||
volumeMounts:
|
||||
- mountPath: /dev/kfd
|
||||
name: kfd
|
||||
- mountPath: /dev/dri
|
||||
name: dri
|
||||
securityContext:
|
||||
privileged: true
|
||||
volumes:
|
||||
- name: kfd
|
||||
hostPath:
|
||||
path: /dev/kfd
|

|
||||
- name: dri
|
||||
hostPath:
|
||||
path: /dev/dri
|
||||
type: Directory
|
||||
```
|
||||
|
||||
Creating of such pods is forbidden unless explicitly allowed in Talos config:
|
||||
|
||||
```yaml
|
||||
# CSI driver requirement
|
||||
cluster:
|
||||
apiServer:
|
||||
admissionControl:
|
||||
- name: PodSecurity
|
||||
configuration:
|
||||
apiVersion: pod-security.admission.config.k8s.io/v1beta1
|
||||
kind: PodSecurityConfiguration
|
||||
exemptions:
|
||||
namespaces:
|
||||
- llama
|
||||
```
|
||||
|
||||
Create the patch like this under `talos/patches/<app>.patch`, add it to `gen-talos-config` target in Makefile and ask operator to apply reconcile Talos config to allow privileged pods in specified namespace.

# LTE Failover Design
|
||||
|
||||
Reference documentation of the as-built LTE failover design. For day-to-day
|
||||
network overview see [network.md](./network.md); for BM806C modem firmware
|
||||
workarounds see [wwan-bm806c-qmi-workaround.md](./wwan-bm806c-qmi-workaround.md).
|
||||
|
||||
## Summary
|
||||
|
||||
| Property | Value |
|
||||
|---|---|
|
||||
| Failover signalling | Symmetric iBGP between D-Link (BIRD2) and CRS (RouterOS) |
|
||||
| BGP AS | 65000 (iBGP; CRS acts as route reflector for D-Link) |
|
||||
| LTE transit path | D-Link wwan ← VLAN 6 (192.168.6.0/24) ← CRS |
|
||||
| D-Link default route source | Learned from CRS via BGP (no static default gateway) |
|
||||
| CRS LTE route source | Learned from D-Link via BGP at distance 200 |
|
||||
| Announcement trigger | wwan interface up/down tracked by BIRD2 device protocol |
|
||||
| Scope | All internet-capable VLANs (vlan2, vlan4, vlan5, vlan6) |
|
||||
| IPv4 NAT | CRS masquerades on `pppoe-gpon` only; D-Link masquerades on `wwan` |
|
||||
| IPv6 NAT | D-Link masquerades IPv6 on `wwan` (no inbound on LTE; outbound only) |
|
||||
| wwan bringup | Triggered by `/etc/init.d/wwan-bringup` after USB re-auth (BM806C wedge fix) |
|
||||
|
||||
## Route exchange
|
||||
|
||||
### CRS announces to D-Link
|
||||
|
||||
| Prefix | Source | Withdrawn when |
|
||||
|---|---|---|
|
||||
| `0.0.0.0/0` | `output.default-originate: if-installed` (active default in main table) | GPON drops or `pppoe-gpon` route inactive |
|
||||
| `2000::/3` | `output.redistribute: static` (HE tunnel default) | `sit1` interface down / HE route inactive |
|
||||
| VLAN subnets (`192.168.0.0/24`, `192.168.1.0/24`, etc.) | `output.redistribute: connected` | never (CRS always reachable on vlan6) |
|
||||
| `100.64.0.0/10` (Tailscale) | `output.redistribute: static` | never |
|
||||
| `172.17.0.0/16` (dockers bridge) | `output.redistribute: connected` | never |
|
||||
| `10.42.0.0/16`, `10.43.0.0/16`, `10.44.0.0/16` (k8s) | reflected via iBGP RR | when k8s BGP session drops |
|
||||
| pod/service/LB IPv6 ranges | reflected via iBGP RR | when k8s BGP session drops |
|
||||
|
||||
Internal prefixes are announced regardless of GPON state. They remain
|
||||
reachable via `192.168.6.1` (directly connected on vlan6) even when GPON
|
||||
fails, so D-Link-originated traffic to internal subnets always routes to
|
||||
CRS rather than incorrectly exiting via wwan.
|
||||
|
||||
The CRS route reflector role (`local.role: ibgp-rr` on the `dlink-lte`
|
||||
connection) allows it to reflect routes learned from the k8s peer (`bgp1`)
|
||||
to D-Link without violating iBGP split-horizon. RFC 4456 `ORIGINATOR_ID`
|
||||
loop prevention is handled automatically by RouterOS — no output filter
|
||||
needed.
|
||||
|
||||
`nexthop-choice: force-self` ensures CRS advertises `192.168.6.1` as the
|
||||
next-hop for all prefixes, rather than the original route's next-hop
|
||||
(which may be unreachable from D-Link, e.g. k8s peer `2001:470:61a3:100::3`).
|
||||
|
||||
### D-Link announces to CRS
|
||||
|
||||
| Prefix | Source | Withdrawn when |
|
||||
|---|---|---|
|
||||
| `0.0.0.0/0` | BIRD2 static `lte_default` via `wwan0` | wwan0 down (device protocol detects) |
|
||||
| `2000::/3` | BIRD2 static `lte_default6` via `wwan0` | wwan0 down |
|
||||
|
||||
BIRD2's `protocol device` tracks wwan0 via netlink in real time; when the
|
||||
interface goes down the static routes become unreachable and BGP withdraws
|
||||
the announcements immediately.
|
||||
|
||||
The BIRD2 static routes use `preference 50` (below the BGP default of 100)
|
||||
so the BGP-learned routes from CRS are preferred for kernel installation
|
||||
on D-Link itself — D-Link's own outbound traffic uses the CRS path when
|
||||
GPON is up. The static routes only exist as triggers for BGP export.
|
||||
|
||||
### D-Link kernel routing table
|
||||
|
||||
| Destination | Source | Kernel metric | Active when |
|
||||
|---|---|---|---|
|
||||
| Internal prefixes (VLANs, k8s, Tailscale) | BGP from CRS, via `192.168.6.1` | 10 (IPv4) / 32 (IPv6) | always (CRS reachable) |
|
||||
| `0.0.0.0/0` | BGP from CRS | 10 | GPON up |
|
||||
| `0.0.0.0/0` | wwan QMI-assigned (qmi.sh) | 100 | wwan up |
|
||||
| `default via wwan IPv6 GW` (non-source-specific) | wwan-bringup script | 1024 | wwan up |
|
||||
| `default from <wwan prefix>/64 via wwan IPv6 GW` (source-specific) | qmi.sh | 100 | wwan up |
|
||||
|
||||
D-Link's own outbound traffic prefers the BGP route (metric 10) over wwan
|
||||
(metric 100). The non-source-specific IPv6 default at metric 1024 exists
|
||||
because qmi.sh only installs a source-specific IPv6 default (constrained
|
||||
to the wwan-assigned `/64` prefix); forwarded traffic from internal
|
||||
subnets would fail routing lookup with "net unreachable" without it.
|
||||
|
||||
### CRS routing table
|
||||
|
||||
| Destination | Source | Distance | Active when |
|
||||
|---|---|---|---|
|
||||
| `0.0.0.0/0` | static via `pppoe-gpon` | 1 | GPON up |
|
||||
| `0.0.0.0/0` | BGP from D-Link via `192.168.6.2` | 200 | wwan up on D-Link |
|
||||
| `2000::/3` | static via `sit1` (HE tunnel) | 1 | sit1 active (HE tunnel works) |
|
||||
| `2000::/3` | BGP from D-Link via `2001:470:61a3:600::2` | 200 | wwan up on D-Link |
|
||||
|
||||
RouterOS distance comparison is straightforward: distance 1 always wins
|
||||
over distance 200. BGP-learned routes activate automatically when the
|
||||
static route becomes inactive (e.g. GPON down → `pppoe-gpon` route
|
||||
inactive → BGP route at distance 200 becomes active).
|
||||
|
||||
## Traffic paths
|
||||
|
||||
### Normal (GPON up)
|
||||
|
||||
```
|
||||
LAN/SRV/IoT → CRS → pppoe-gpon → ISP
|
||||
D-Link own → uplink → CRS → pppoe-gpon → ISP
|
||||
(via BGP-learned default at kernel metric 10)
|
||||
```
|
||||
|
||||
wwan is connected and D-Link announces the LTE default to CRS, but CRS
|
||||
ignores it (distance 200 loses to distance 1). D-Link uses the
|
||||
CRS-announced default (metric 10) for its own traffic, not wwan
|
||||
(metric 100).
|
||||
|
||||
### Failover (GPON down)
|
||||
|
||||
```
|
||||
LAN/SRV/IoT → CRS → vlan6 (→192.168.6.2) → D-Link → wwan → Orange LTE
|
||||
D-Link own → wwan → Orange LTE
|
||||
```
|
||||
|
||||
CRS distance-1 routes go inactive → distance-200 BGP routes from D-Link
|
||||
activate. D-Link receives forwarded traffic on uplink, routes it via the
|
||||
non-source-specific wwan default (metric 1024), fw4 masquerades the
|
||||
source, packet exits via wwan. Return traffic reverses through masquerade
|
||||
state and forwards back to CRS via the established connection-tracking
|
||||
entry.
|
||||
|
||||
When CRS withdraws its BGP-announced default to D-Link (because GPON is
|
||||
down and CRS has no default to announce), D-Link's kernel default at
|
||||
metric 10 is removed, leaving the wwan default at metric 100 as the
|
||||
preferred route for D-Link's own traffic.
|
||||
|
||||
### Failure detection
|
||||
|
||||
- **D-Link crashes / power loss** → BGP session drops after `hold-time: 30s`
|
||||
→ CRS withdraws all D-Link-learned routes → internet unavailable if
|
||||
GPON also down (acceptable single-point-of-failure for home network)
|
||||
- **wwan modem goes down** → BIRD2 device protocol detects wwan0 down →
|
||||
static `lte_default` / `lte_default6` become unreachable → BGP withdraws
|
||||
announcements → CRS removes BGP-learned default
|
||||
- **GPON drops** → `pppoe-gpon` interface down → CRS distance-1 default
|
||||
route inactive → distance-200 BGP route activates → CRS withdraws its
|
||||
default-originate announcement to D-Link (since no default is installed
|
||||
any more) → D-Link's kernel default-via-CRS is removed → D-Link uses
|
||||
wwan kernel default → traffic flows from CRS via vlan6 → D-Link → wwan
|
||||
|
||||
All transitions are automatic and driven by interface state. No active
|
||||
probing (Netwatch / mwan3), no scripts toggling routes.
|
||||
|
||||
## NAT rules
|
||||
|
||||
NAT rules are always active, matched by output interface. No
|
||||
failover-triggered toggling needed.
|
||||
|
||||
### CRS (RouterOS)
|
||||
|
||||
- IPv4 `masquerade` on `srcnat` chain with `out-interface: pppoe-gpon`.
|
||||
Only the GPON public interface gets masqueraded — `vlan6` is internal
|
||||
and never natted, `sit1` (IPv6) has its own dedicated src-nat for the
|
||||
Tailscale prefix.
|
||||
- IPv6 `src-nat tailnet to internet` on `srcnat` chain for Tailscale
|
||||
prefix (`fd7a:115c:a1e0::/48`) to `2001:470:61a3:600::/64`, applied
|
||||
on `out-interface-list: wan`. Fires regardless of whether the
|
||||
egress is `sit1` or `vlan6`.
|
||||
|
||||
### D-Link (OpenWrt fw4)
|
||||
|
||||
- `wwan` zone has `option masq '1'` and `option masq6 '1'`. All traffic
|
||||
exiting via wwan (own outbound + forwarded from `uplink`) is
|
||||
source-NAT'd, IPv4 to the wwan-assigned CG-NAT IP, IPv6 to the
|
||||
wwan-assigned `/128` from the Orange-assigned `/64` prefix.
|
||||
- Forwarding rule `uplink → wwan` allows MikroTik-routed traffic to
|
||||
egress via wwan during failover. Default forward policy on the wwan
|
||||
zone stays REJECT.
|
||||
|
||||
## BGP / route reflection details
|
||||
|
||||
### CRS connection config
|
||||
|
||||
```
|
||||
/routing/bgp/connection set dlink-lte \
|
||||
remote.address=192.168.6.2/32 \
|
||||
local.role=ibgp-rr \
|
||||
nexthop-choice=force-self \
|
||||
output.redistribute=connected,static \
|
||||
output.default-originate=if-installed \
|
||||
hold-time=30s keepalive-time=10s
|
||||
```
|
||||
|
||||
`output.default-originate=if-installed` is required for the `0.0.0.0/0`
|
||||
advertisement because RouterOS does not advertise interface-gateway
|
||||
static routes (gateway=`pppoe-gpon`) via plain `output.redistribute=static`.
|
||||
`default-originate` advertises a synthetic default whenever any active
|
||||
default exists in the routing table, regardless of how it was installed.
|
||||
|
||||
### IPv6 Extended Next Hop workaround
|
||||
|
||||
RouterOS uses BGP Extended Next Hop Encoding (RFC 5549 / RFC 8950) for
|
||||
IPv6 routes on this iBGP session, advertising them with an IPv4-mapped
|
||||
next-hop (`::ffff:192.168.6.1`). The Linux kernel does not support
|
||||
installing IPv6 routes with IPv4 next-hops, so BIRD2 cannot push them
|
||||
directly to the kernel.
|
||||
|
||||
There is no way to disable ENHE on RouterOS — `local.address`,
|
||||
`nexthop-choice: force-self`, and output `set gw` filters all fail to
|
||||
override it. The workaround is on the BIRD2 side: an import filter on
|
||||
the BGP IPv6 channel rewrites `gw` to CRS's native IPv6 address
|
||||
(`2001:470:61a3:600::1`) before the route is exported to the kernel.
|
||||
|
||||
```
|
||||
ipv6 {
|
||||
extended next hop yes;
|
||||
import filter {
|
||||
gw = 2001:470:61a3:600::1;
|
||||
accept;
|
||||
};
|
||||
...
|
||||
};
|
||||
```
|
||||
|
||||
The reverse direction (D-Link → CRS) was solved cleanly via BIRD2 export
|
||||
filter setting `bgp_next_hop = 2001:470:61a3:600::2`, since BGP-level
|
||||
attribute manipulation isn't constrained by kernel limitations.
|
||||
|
||||
### Direct protocol on D-Link
|
||||
|
||||
BIRD2 needs to know about the directly connected `192.168.6.0/24` and
|
||||
`2001:470:61a3:600::/64` subnets on `eth0.6` to resolve BGP next-hops.
|
||||
The `protocol direct { interface "eth0.6"; }` declaration provides this;
|
||||
without it BIRD2 marks all CRS-learned routes as unreachable.
|
||||
|
||||
## BM806C modem cold-boot wedge
|
||||
|
||||
The BM806C firmware enters a permanently broken state on cold boot:
|
||||
`/dev/cdc-wdm0` exists, kernel driver attaches, but uqmi commands return
|
||||
`"Failed to connect to service"` indefinitely. UIM (SIM) QMI service
|
||||
specifically never comes up.
|
||||
|
||||
Recovery requires a USB device re-enumeration. The `/etc/init.d/wwan-bringup`
|
||||
service writes `0` then `1` to `/sys/bus/usb/devices/1-1/authorized` on
|
||||
boot, then triggers `ifup wwan`. After re-auth the modem completes its
|
||||
QMI initialization within ~1 second.
|
||||
|
||||
Full investigation: see [wwan-bm806c-qmi-workaround.md](./wwan-bm806c-qmi-workaround.md).

# Network topology
|
||||
|
||||
Network consists of 2 MikroTik routers, 1 OpenWRT router, UniFi AP, Netgear switch. Internet is connected via GPON ONU connected to MikroTik router with fallback LTE network in D-Link router. They are connected like in the diagram below below:

## Internal structure
|
||||
|
||||
Network is divided to multiple VLANs to enforce strict access control rules using stateful firewall. There are 6 VLANs:
|
||||
|
||||
- 1: Management network<br>
|
||||
No internet access, no outbound access to other networks<br>
|
||||
IP: 192.168.255.0/24<br>
|
||||
Static IP configuration
|
||||
- 2: General purpose LAN<br>
|
||||
Access to every other network<br>
|
||||
IP: 192.168.0.0/24 / 2001:470:61a3:9::/64<br>
|
||||
Gateway: 192.168.0.1 / 2001:470:61a3:9:ffff:ffff:ffff:ffff<br>
|
||||
DHCP / SLAAC
|
||||
- 3: Cameras<br>
|
||||

|
||||
Internet access only<br>
|
||||
IP: 192.168.5.0/24 / 2001:470:61a3:a::/64<br>
|
||||
Gateway: 192.168.5.1 / 2001:470:61a3:a:ffff:ffff:ffff:ffff<br>
|
||||
DHCP / SLAAC, accessible via separate WiFi network "szafa" from D-Link for absolutely untrusted Tuya and like devices
|
||||
- 6: Internet access for OpenWRT<br>
|
||||

|
||||
IP: 192.168.6.0/24 / 2001:470:61a3:600::/64<br>

|

|
||||
There are also networks, which are not VLANs, but are routed:
|
||||
|
||||
- Tailscale, container on CRS<br>
|
||||
Access to every other network, including internet (exit node)<br>
|
||||
IP: 100.64.0.0/10 / fd7a:115c:a1e0::/48<br>
|
||||
Allocations managed completely by Tailscale
|
||||
- Kubernetes cluster, routes exposed to CRS via BGP using Cilium<br>
|
||||
Access to internet, cameras<br>
|
||||
Pods: 10.42.0.0/16 (/24 subnet per node), 2001:470:61a3:200::/104 (/120 subnet per node)<br>
|
||||
Service: 10.43.0.0/16, 2001:470:61a3:300::/112<br>
|
||||
LoadBalancer: 10.44.0.0/16, 2001:470:61a3:400::/112<br>
|
||||
Assigned by Cilium MultiPool IPAM (pods), kube-apiserver (services), Cilium LB (LoadBalancer)<br>
|
||||
Native IP routing, no overlay, VXLAN etc.<br>
|
||||
LoadBalancer is reachable from the internet using IPv6 directly or IPv4 port forwards, leveraging ECMP.
|
||||
- GPON ONU management<br>
|
||||
IP: 192.168.100.0/24<br>
|
||||
Static assignment on CRS, access to factory IP of ONU
|
||||
- Containers on CRS<br>
|
||||
Access to every other network<br>
|
||||
IP: 172.17.0.1/16, 2001:470:61a3:500::/64<br>
|
||||
Static IP management
|
||||
|
||||
Whole network is designed to eliminate VLANs, overlays where unnecessary to keep things simple. Only NAT rules are:
|
||||
|
||||
- Masquerade outbound IPv4 via GPON PPPoE
|
||||
- Masquerade to GPON ONT management<br>
|
||||
It doesn't have a gateway configured, we want to access it from other networks so we need to talk to it as if we were in the same subnet
|
||||
- src-nat tailscale IPv6 to internet<br>
|
||||
Tailscale assigns IPv6 from private subnet with no way to configure it, so the assigned IPs are not routable
|
||||
- IPv4 port forwards from GPON PPPoE to respective services
|
||||
|
||||
There is also an UPnP and NAT-PMP enabled to automatically configure port forwards from LAN.
|
||||
|
||||
## Uplink
|
||||
|
||||
Main internet connection is a fibre optics (GPON) service from my ISP, which includes static, publicly reachable IPv4 address. I'm using my own GPON ONU, which is a SFP+ module inserted to CRS, I configured it to clone ISP-provided Huawei box. I'm authenticated using PPPoE credentials and it hands out public IP address directly to the router.
|
||||
|
||||
One of quirks of the ISP is that it doesn't allow incoming port 53/DNS connections, which disables me from hosting DNS server, I was wanting to do to configure reverse DNS for pods IPv6. The configuration for public DNS server is still remaining cluster.
|
||||
|
||||
The ISP does not provide any IPv6 connectivity at all. For that purpose I'm using [tunnel broker from Hurricane Electric](https://tunnelbroker.net/), which gives /48 routed prefix that I divided to /64 networks.
|
||||
|
||||
The backup internet link is an LTE connection via the embedded BroadMobi BM806C modem in the D-Link router (Orange Poland, dual-stack). The SIM was previously in a USB modem attached directly to the CRS; it was moved to the D-Link to reduce rack clutter and gain access to a proper modem interface. The modem requires firmware-level workarounds — QMI data-plane bugs, a cold-boot UIM wedge that needs USB re-enumeration — documented in [LTE failover (BroadMobi BM806C / D-Link DWR-921 C1) — QMI data-plane workaround](./wwan-bm806c-qmi-workaround.md).
|
||||
|
||||
Failover is implemented using iBGP between the D-Link (BIRD2, AS 65000) and the CRS (`local.role: ibgp-rr` so CRS acts as route reflector for D-Link). The D-Link announces `0.0.0.0/0` and `2000::/3` to the CRS whenever its `wwan` interface is up. The CRS installs these at BGP distance 200 — below the GPON static default at distance 1 — so they only become active when GPON fails. The CRS in turn announces all its connected and static routes (VLAN subnets, Tailscale, k8s pod/service/LB prefixes via RR reflection) to the D-Link so it always has explicit routes to internal subnets regardless of WAN state. The D-Link's own default route also comes from this BGP session (no static gateway on the uplink interface); when the CRS withdraws the default on GPON failure, the D-Link falls back to its wwan kernel route at metric 100.
|
||||
|
||||
For full design rationale, route exchange tables, and implementation notes including the BGP Extended Next Hop workarounds, see [LTE failover design](./lte-failover-design.md).
|
||||
|
||||
During LTE failover, all VLANs route through `vlan6` to the D-Link, which forwards traffic out `wwan` and masquerades it (IPv4 and IPv6 via fw4 `masq`/`masq6`). IPv6 is outbound-only — the carrier enforces an inbound firewall, and there is no routed prefix large enough to cover all internal subnets without NAT.
|
||||
|
||||
## Configuration management
|
||||
|
||||
Currently, only CRS and D-Link are managed in this repository. Other devices currently have been configured manually using dedicated web interface/tools. The end goal is to have full configuration as code.
|
||||
|
||||
Network devices are configured using Ansible with playbooks under [ansible/playbooks](../ansible/playbooks/) subdirectory:
|
||||

# LTE failover (BroadMobi BM806C / D-Link DWR-921 C1) — QMI data-plane workaround

|
||||
## TL;DR
|
||||
|
||||
The embedded BroadMobi BM806C modem in the D-Link DWR-921 has **three
|
||||
independent bugs** in its firmware (`M1.2.0_E1.0.1_A1.1.8`, the only
|
||||
build that has ever shipped), all of which must be worked around for a
|
||||
usable LTE uplink:
|
||||
The embedded BroadMobi BM806C modem in the D-Link DWR-921 attaches to
|
||||
LTE, gets assigned IP addresses through QMI, reports `"connected"` —
|
||||
but **no downlink data passes**. Every TCP SYN we send out is dropped
|
||||
somewhere between the modem and the host kernel, and we never see a
|
||||
SYN-ACK. After several hours of layered diagnostics we identified two
|
||||
independent issues, both of which must be fixed for QMI to work on this
|
||||
device:
|
||||
|
||||
1. **Cold-boot UIM wedge.** On every cold boot, the modem's UIM (SIM)
|
||||
QMI service comes up permanently broken: `--uim-get-sim-state`
|
||||
returns `{}`, `--get-imsi` returns `"UIM uninitialized"`, and
|
||||
`AT+CPIN?` returns `+CME ERROR: SIM busy`. The modem **never
|
||||
recovers on its own** (verified at uptime 21 min). A single USB
|
||||
re-enumeration (`echo 0 > /sys/.../1-1/authorized; sleep 3; echo 1
|
||||
> ...`) forces the modem to redo its internal QMI init from
|
||||
scratch, after which UIM comes up within ~1 s. The
|
||||
`wwan-bringup` service installed by this role does the
|
||||
re-enumeration unconditionally on boot, then calls `ifup wwan`.

## Symptoms
|
||||
|
||||
### Boot-wedge symptoms (bug 1)
|
||||
|
||||
When the modem boots into the UIM-wedged state, all of the following
|
||||
hold simultaneously:
|
||||
|
||||
- `/dev/cdc-wdm0` exists, `wwan0` netdev exists, `qmi_wwan` driver is
|
||||
bound to `1-1:1.4` — kernel side looks fine
|
||||
- `ifup wwan` runs forever in the SIM-init loop:
|
||||
`wwan: SIM in illegal state - Power-cycling SIM` repeating every ~8 s
|
||||
- `uqmi -d /dev/cdc-wdm0 --uim-get-sim-state` returns `{}` (empty
|
||||
body — no `card_application_state` field at all)
|
||||
- `uqmi -d /dev/cdc-wdm0 --get-imsi` returns the QMI string
|
||||
`"UIM uninitialized"`
|
||||
- `uqmi -d /dev/cdc-wdm0 --get-pin-status` returns
|
||||
`"Invalid arguments given"` (uqmi cannot allocate a UIM client
|
||||
because the modem-side service has not registered)
|
||||
- AT side: `AT+CFUN?` returns `+CFUN: 1` (modem firmware is alive),
|
||||
`AT+CPIN?` returns `+CME ERROR: SIM busy`, and `AT+CREG?` /
|
||||
`AT+CEREG?` / `AT+COPS?` all return bare `ERROR`
|
||||
- This persists indefinitely; we measured no recovery at uptime
|
||||
21 min
|
||||
|
||||
### Data-plane symptoms (bugs 2 and 3)
|
||||
|
||||
When the modem comes up cleanly but the qmi.sh patches are missing or
|
||||
the wrong `--start-network` invocation is used, all of the following
|
||||
are true at the same time:
|
||||
When QMI is broken on this modem, all of the following are true at the
|
||||
same time:
|
||||
|
||||
- `ifup wwan` succeeds, `ifstatus wwan` reports `"up": true`
|
||||
- `wwan0` has a valid CG-NAT IPv4 (`10.x.x.x/30`) and IPv6
