# Deploying FlatRender (Gitea CI/CD → 171.22.25.73, behind mirror-nginx)
Push to **Gitea** triggers `.gitea/workflows/ci-cd.yml`: a frontend `tsc` check, then a
self-hosted `deploy` job that builds the whole compose stack and brings it up. The
existing central **mirror-nginx** (owns 80/443, manual TLS certs) reverse-proxies the
three public domains to FlatRender's host ports — FlatRender does **not** run Caddy here.
GitHub (`origin`) stays a backup and never deploys.
Stack: gateway · identity · content · studio (.NET/Go) · file · render · notification
(Go) · Next.js frontend · Postgres · MinIO. All package installs route through
`mirror.soroushasadi.com` (Nexus).
```
mirror-nginx (:443, /etc/ssl/flatrender)
flatrender.ir → 171.22.25.73:1600 (fr2-frontend)
api.flatrender.ir → 171.22.25.73:1605 (fr2-gateway)
storage.flatrender.ir → 171.22.25.73:1610 (fr2-minio)
```
## One-time setup (do these BEFORE the first `git push gitea master`)
1. **DNS** — this box sits BEHIND NAT: its interface IP is `171.22.25.73` (private),
public NAT IPs are `31.171.101.127/.211`, and inbound 443 normally arrives via the
edge/CDN `185.239.1.100` (same entry your other sites use, e.g. `meezi.ir`). So a new
domain must enter the SAME way the others do — either:
- register `flatrender.ir` + `api` + `storage` + `www` in that edge/CDN (origin = this
server) and point DNS there, **or**
- bypass the CDN and point DNS straight at the server's public IP (like the hokm `api`
subdomain does — "must bypass").
Pointing DNS at a random/registrar IP shows that host's default page (e.g. a "not
licensed" page), NOT FlatRender.
2. **TLS cert** — ⚠️ mirror-nginx mounts cert dirs INDIVIDUALLY, so a fresh
`/etc/ssl/flatrender/` on the host is invisible inside the container. **Nest the cert
under an already-mounted dir** (the conf references this path):
```bash
mkdir -p /etc/ssl/soroushasadi/flatrender
cp <yourcert>/fullchain.pem /etc/ssl/soroushasadi/flatrender/
cp <yourcert>/privateKey.pem /etc/ssl/soroushasadi/flatrender/
```
Cert must cover `flatrender.ir` + `api.` + `storage.` (wildcard `*.flatrender.ir` + apex, or SAN).
3. **mirror-nginx** — add the server blocks from [`mirror-nginx-flatrender.conf`](./mirror-nginx-flatrender.conf)
to the proxy's `http{}` (the host file is `/root/mirror-server/nginx/nginx.conf`), then:
`docker exec mirror-nginx nginx -t && docker exec mirror-nginx nginx -s reload`.
⚠️ If you edited the conf with `sed -i` (which swaps the file inode), the running
container keeps the old inode → `docker restart mirror-nginx` instead (~3s blip).
Verify locally (bypasses DNS): `curl -sk --resolve flatrender.ir:443:127.0.0.1 https://flatrender.ir/ | head -c 60`
must show `<html lang="fa" dir="rtl">`. (Do this after the first deploy is up, or it 502s.)
4. **ENV_FILE secret** — at `…/soroushdes/flatrender/settings/secrets`, create `ENV_FILE`
from [`ENV_FILE.production.example`](./ENV_FILE.production.example) (already filled for
flatrender.ir; generate each secret with `openssl rand -hex 32`).
5. **Gitea Actions** enabled for this repo; act_runner has the `self-hosted:host` label
(the standard box already has this). daemon.json already mirrors Docker Hub via Nexus.
## Go live
```bash
git push gitea master # triggers CI + deploy
```
Watch `https://git.soroushasadi.com/soroushdes/flatrender/actions`. First run ~1525 min
(cold Nexus cache + all images build). When the deploy is green, add/reload the nginx
blocks (step 3) and visit `https://flatrender.ir`.
## Host ports (must be free on 171.22.25.73)
`1600` frontend · `1605` gateway · `1610` MinIO · `1611` MinIO console. Postgres (5432)
and render (5010) bind to `127.0.0.1` only. Avoid `:3000` (Gitea), `:8081-8083` (Nexus),
`:1500/1505/1520` (bargevasat), `:3010/3101-3103/5080/5081` (meezi), `:3020`, `:2569`.
Change them via `FRONTEND_PORT`/`GATEWAY_PORT`/`MINIO_PORT` in the secret if any collide.
## First-run notes
- **Migrations** auto-run once via `deploy/postgres-initdb/00-init.sh` (mounted as the
whole `/docker-entrypoint-initdb.d` directory — a single-file bind mount left a stale
empty dir → "Is a directory") when the Postgres volume is first created. Later schema
changes are applied manually with `psql` (the volume persists). ⚠️ If a deploy ever
ran with a wrong/empty secret, the volume bakes the wrong password + may skip init →
`docker rm -f fr2-postgres && docker volume rm flatrender_pgdata` (only while there's
no real data) then re-run, so it re-inits with the current password + migrations.
- **Rendering** — no After Effects node on the server, so `RENDER_DEV_WORKER=false`.
Disable rendering in **Admin → فارم رندر → موتور رندر** so users see an "unavailable"
notice instead of jobs that never finish. Point real render nodes at the server later.
- **MinIO public URLs** — verify an uploaded image + a render download resolve over
`https://storage.flatrender.ir`. If not, recheck `MINIO_HOST_ENDPOINT` /
`MINIO_HOST_USE_SSL` / `NEXT_PUBLIC_MINIO_URL` in the secret and redeploy.
## Redeploy / rotate secrets
Edit `ENV_FILE` in Gitea (or push any commit) → the deploy re-runs. It backs up the DB to
`/opt/flatrender-backups/` before each deploy and never runs `docker compose down -v`.
Changing a `NEXT_PUBLIC_*` value only takes effect after the redeploy (baked at build).
