# Kubernetes / Helm
|
||||
|
||||
Deploy the published Docker Hub runtime image with the chart in
|
||||
[`helm/openstack-api-simulator`](../helm/openstack-api-simulator).
|
||||
|
||||
Image: [`inecs/openstack-api-simulator`](https://hub.docker.com/r/inecs/openstack-api-simulator)
|
||||
|
||||
The chart mirrors Docker Compose:
|
||||
|
||||
| Component | Role |
|
||||
|---|---|
|
||||
| **simulator** Deployment | FastAPI app on `:8080` |
|
||||
| **api-gateway** Deployment | nginx multi-port OpenStack gateway |
|
||||
| **PostgreSQL** StatefulSet | Bundled Postgres 17 (optional) |
|
||||
| **migrate** initContainer | Idempotent schema migrations |
|
||||
| **seed** Job (optional) | `minimal` or `demo` lab data |
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Kubernetes 1.27+ (or comparable)
|
||||
- Helm 3.14+
|
||||
- For Ingress TLS: [Ingress NGINX](https://kubernetes.github.io/ingress-nginx/) and
|
||||
[cert-manager](https://cert-manager.io/)
|
||||
|
||||
Example cert-manager install:
|
||||
|
||||
```bash
|
||||
kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.17.2/cert-manager.yaml
|
||||
```
|
||||
|
||||
## Quick install (Hub release + Ingress + Let's Encrypt)
|
||||
|
||||
From a git checkout of this repository:
|
||||
|
||||
```bash
|
||||
helm upgrade --install os-sim ./helm/openstack-api-simulator \
|
||||
-n openstack-sim --create-namespace \
|
||||
-f ./helm/openstack-api-simulator/values-ingress-example.yaml \
|
||||
--set certManager.email=you@example.com \
|
||||
--set ingress.hosts[0].host=os-sim.example.com \
|
||||
--set ingress.tls[0].hosts[0]=os-sim.example.com \
|
||||
--set secret.ticketSigningKey="$(openssl rand -hex 32)" \
|
||||
--set postgresql.auth.password="$(openssl rand -hex 16)"
|
||||
```
|
||||
|
||||
What this does:
|
||||
|
||||
1. Pulls `inecs/openstack-api-simulator:0.1.0`.
|
||||
2. Installs bundled PostgreSQL 17 (`postgres:17.5-bookworm`).
|
||||
3. Runs schema migrations in an init container (idempotent).
|
||||
4. Seeds the **demo** lab profile (`seed.enabled=true`, ~1000 servers).
|
||||
5. Deploys nginx **api-gateway** with OpenStack default ports (5000, 8774, 9696, …).
|
||||
6. Creates `ClusterIssuer` resources (`letsencrypt-prod` / `letsencrypt-staging`).
|
||||
7. Creates an Ingress → gateway `:5000` (Keystone + Web UI) with TLS.
|
||||
|
||||
DNS for `os-sim.example.com` must point at your Ingress controller. Then:
|
||||
|
||||
```bash
|
||||
kubectl -n openstack-sim get certificate,ingress,pods
|
||||
curl -sS https://os-sim.example.com/health/ready
|
||||
open https://os-sim.example.com/
|
||||
```
|
||||
|
||||
Default seeded login: `admin` / `secret` (project `demo` or `admin`, domain `Default`).
|
||||
|
||||
### Staging first (recommended)
|
||||
|
||||
```bash
|
||||
helm upgrade --install os-sim ./helm/openstack-api-simulator \
|
||||
-n openstack-sim --create-namespace \
|
||||
-f ./helm/openstack-api-simulator/values-ingress-example.yaml \
|
||||
--set certManager.email=you@example.com \
|
||||
--set certManager.useStaging=true \
|
||||
--set ingress.hosts[0].host=os-sim.example.com \
|
||||
--set ingress.tls[0].hosts[0]=os-sim.example.com \
|
||||
--set secret.ticketSigningKey="$(openssl rand -hex 32)"
|
||||
```
|
||||
|
||||
Use `curl -k` against the staging CA. Flip `certManager.useStaging=false` for production.
|
||||
|
||||
## Minimal install (ClusterIP + port-forward)
|
||||
|
||||
```bash
|
||||
helm upgrade --install os-sim ./helm/openstack-api-simulator \
|
||||
-n openstack-sim --create-namespace \
|
||||
--set secret.ticketSigningKey="$(openssl rand -hex 32)" \
|
||||
--set seed.enabled=true \
|
||||
--set seed.profile=minimal
|
||||
|
||||
kubectl -n openstack-sim port-forward \
|
||||
svc/os-sim-openstack-api-simulator-gateway \
|
||||
5000:5000 8774:8774 9696:9696 9292:9292 8776:8776
|
||||
```
|
||||
|
||||
| URL | Service |
|
||||
|---|---|
|
||||
| http://127.0.0.1:5000/ | Keystone + console |
|
||||
| http://127.0.0.1:8774/v2.1/ | Nova |
|
||||
| http://127.0.0.1:9696/v2.0/ | Neutron |
|
||||
|
||||
Full port matrix: [ports.md](ports.md).
|
||||
|
||||
## External PostgreSQL
|
||||
|
||||
```bash
|
||||
helm upgrade --install os-sim ./helm/openstack-api-simulator \
|
||||
-n openstack-sim --create-namespace \
|
||||
--set postgresql.enabled=false \
|
||||
--set secret.ticketSigningKey="$(openssl rand -hex 32)" \
|
||||
--set secret.databaseUrl='postgresql://user:pass@pg.example.com:5432/openstack_simulator'
|
||||
```
|
||||
|
||||
Or use `secret.existingSecret` with keys `DATABASE_URL` and `TICKET_SIGNING_KEY`.
|
||||
|
||||
## How the api-gateway works
|
||||
|
||||
Same model as Compose (`docker/gateway/openstack-ports.conf`):
|
||||
|
||||
1. Client connects to a **service-specific port** (e.g. Nova `8774`).
|
||||
2. nginx sets `X-OpenStack-Service` and `X-Forwarded-Port`.
|
||||
3. FastAPI rewrites to `/_os/<service>/…` so `/v3` (Keystone vs Cinder) does not collide.
|
||||
|
||||
Ingress (when enabled) fronts **Keystone/UI on port 5000**. For Nova/Neutron from
|
||||
outside the cluster, either:
|
||||
|
||||
- `kubectl port-forward` additional ports, or
|
||||
- expose `*-gateway` as `LoadBalancer` / `NodePort` (`gateway.service.type`), or
|
||||
- add extra Ingress rules / TCP services for those ports.
|
||||
|
||||
## How TLS issuance works
|
||||
|
||||
When `certManager.enabled=true` and `certManager.createClusterIssuer=true`, the
|
||||
chart creates ACME `ClusterIssuer` objects (HTTP-01). The Ingress template adds:
|
||||
|
||||
```yaml
|
||||
metadata:
|
||||
annotations:
|
||||
cert-manager.io/cluster-issuer: letsencrypt-prod
|
||||
spec:
|
||||
tls:
|
||||
- secretName: openstack-api-simulator-tls
|
||||
hosts: [os-sim.example.com]
|
||||
```
|
||||
|
||||
The chart does **not** install cert-manager or the Ingress controller.
|
||||
|
||||
## Operations
|
||||
|
||||
```bash
|
||||
# logs
|
||||
kubectl -n openstack-sim logs -l app.kubernetes.io/component=simulator -f
|
||||
kubectl -n openstack-sim logs -l app.kubernetes.io/component=gateway -f
|
||||
|
||||
# reseed minimal
|
||||
kubectl -n openstack-sim exec deploy/os-sim-openstack-api-simulator -- \
|
||||
python -m app.openstack.seed_cli --profile minimal
|
||||
|
||||
# reseed demo cloud
|
||||
kubectl -n openstack-sim exec deploy/os-sim-openstack-api-simulator -- \
|
||||
python -m app.openstack.seed_cli --profile demo
|
||||
|
||||
# activate OpenStack pack series
|
||||
kubectl -n openstack-sim set env deploy/os-sim-openstack-api-simulator \
|
||||
OPENSTACK_SERIES=caracal
|
||||
# then restart the pod / helm upgrade with --set config.openstackSeries=caracal
|
||||
|
||||
# uninstall
|
||||
helm -n openstack-sim uninstall os-sim
|
||||
```
|
||||
