# 04 — SWAG Nginx Proxy Configs (Prod)

## Context
Same template files as test (`swag/proxy-confs/*.conf.tpl`), different env vars.
The pipeline processes templates with prod-specific subdomain values.

## Required env vars (in `.env` on storagebox `prod/secrets/iklim.co/.env.prod`)

```bash
API_SUBDOMAIN=api.iklim.co
APIGW_SUBDOMAIN=apigw.iklim.co
RABBITMQ_SUBDOMAIN=rabbitmq.iklim.co
GRAFANA_SUBDOMAIN=grafana.iklim.co
RESTRICTED_IP_1=78.187.87.109
RESTRICTED_IP_2=95.70.151.248
```

## Template files (already created in test step 04)

- `swag/site-confs/default.conf`
- `swag/proxy-confs/api.conf.tpl`
- `swag/proxy-confs/apigw.conf.tpl`
- `swag/proxy-confs/rabbitmq.conf.tpl`
- `swag/proxy-confs/grafana.conf.tpl`

No new files to create — the same templates work for both environments.

## Deploy step (handled by pipeline — see `08-deploy-pipeline-update.md`)

```bash
set -a; . ./.env; set +a
export RESTRICTED_IP_1="78.187.87.109"
export RESTRICTED_IP_2="95.70.151.248"

sudo mkdir -p /opt/iklimco/swag/proxy-confs /opt/iklimco/swag/site-confs

for tpl in swag/proxy-confs/*.conf.tpl; do
  out="/opt/iklimco/swag/proxy-confs/$(basename "${tpl%.tpl}")"
  envsubst < "$tpl" | sudo tee "$out" > /dev/null
  echo "✅ $out"
done

sudo cp swag/site-confs/default.conf /opt/iklimco/swag/site-confs/default.conf
```

With `API_SUBDOMAIN=api.iklim.co`, the output file `/opt/iklimco/swag/proxy-confs/api.conf`
will contain `server_name api.iklim.co;` — correct for prod.

## Verification

After deploy, on service-1:
```bash
cat /opt/iklimco/swag/proxy-confs/api.conf | grep server_name
```
Expected: `server_name api.iklim.co;`

```bash
docker exec $(docker ps -q -f name=iklimco_swag) nginx -t
```
Expected: `syntax is ok`

```bash
curl -si https://api.iklim.co/health
```
Expected: APISIX response with valid `*.iklim.co` cert.

## Notes
- `Prometheus` is intentionally NOT exposed via SWAG. Access it via Grafana
  (internal connection: `http://prometheus:9090`) or SSH tunnel.
- If additional restricted-access subdomains are needed in the future, create a new
  `swag/proxy-confs/<name>.conf.tpl` following the same pattern.
