# SiMS HQ — Deployment Paths & Names (reference)

The single source of truth for **where things live and what they're called** in production.
If a name here disagrees with a command you're about to run, this file wins. Server is the
existing company **Amazon Linux 2** EC2 box; HQ runs as its own Docker container beside the
other apps. (D20 target, revised: `.in` not `.com`, Docker not RDS — see notes at bottom.)

## Identity

| Thing | Value |
|---|---|
| Public URL | `https://hq.simssoftware.in` |
| EC2 public IP (Elastic) | `13.232.53.115` |
| DNS record | `A` · `hq` → `13.232.53.115`, in the **simssoftware.in** zone (same place as `gitea.simssoftware.in`) |
| SSH user | `ec2-user` |
| Box hostname | `ip-172-31-14-238` |

## Git

| Thing | Value |
|---|---|
| Repo (Gitea) | `https://gitea.simssoftware.in/SIMS/sims-hq.git` (moved from `gitadmin/`; old URL redirects) |
| Branch | `main` |

## Folders on the box

| Path | What it is |
|---|---|
| `/usr/share/nginx/sims-hq` | **App folder** — the whole project (owned by `ec2-user`). Docker builds from here. |
| `/usr/share/nginx/sims-hq/apps/hq/.env` | **Environment file** — DB URL + secrets (chmod 600). |
| `/usr/share/nginx/sims-hq/deploy/sims.hq.conf` | nginx vhost **source** (copied into nginx below). |
| `/etc/nginx/conf.d/sims.hq.conf` | **Live nginx vhost** (must end in `.conf`; `sudo` to edit). |
| `/etc/ssl/sims/sims.crt` · `/etc/ssl/sims/sims.key` | Wildcard TLS cert for `*.simssoftware.in` (shared). |

> Rule: anything under `/etc/` (nginx, ssl) is **root-owned** — create/edit it in the PuTTY
> terminal with `sudo`, never via WinSCP. WinSCP can only write `/usr/share/nginx/sims-hq`
> (after `chown ec2-user`) and your home folder.

## Docker

| Thing | Value |
|---|---|
| HQ container name | `sims-hq` |
| HQ image | `sims-hq` (built from `Dockerfile`) |
| Compose file | `/usr/share/nginx/sims-hq/docker-compose.yml` |
| HQ port (host→container) | `127.0.0.1:5182` → `5182` (localhost only; nginx proxies to it) |
| Postgres container | `accurate-postgres` (image `postgres`) — **shared** with other apps |
| Postgres port (host) | `0.0.0.0:5432` |
| How HQ reaches Postgres | `host.docker.internal:5432` (via the host gateway) |

## Database (inside `accurate-postgres`)

| Thing | Value |
|---|---|
| Superuser (admin) | `postgres` (connect via `sudo docker exec -i accurate-postgres psql -U postgres`) |
| HQ database | `hq` |
| HQ role (login) | `hq` |
| HQ password | *generated on the box*, stored only in `apps/hq/.env` — never in git |
| Connection string | `postgres://hq:<password>@host.docker.internal:5432/hq` |

## App environment (`apps/hq/.env`)

| Key | Value |
|---|---|
| `HQ_PORT` | `5182` |
| `HQ_OWNER_EMAIL` | `simssoftware13@gmail.com` (first-boot owner login) |
| `DATABASE_URL` | `postgres://hq:<password>@host.docker.internal:5432/hq` |
| `SIMS_PIN_PEPPER` | generated on box — **set once, never change** |
| `HQ_SECRET_KEY` | generated on box (needed before Gmail) |

## Owner login

| Thing | Value |
|---|---|
| Email | `simssoftware13@gmail.com` |
| First password | printed **once** in `sudo docker logs sims-hq` on first boot — change immediately |

## Everyday commands (run from `/usr/share/nginx/sims-hq`)

| Do this | Command |
|---|---|
| Build + start | `sudo docker compose up -d --build` |
| View logs | `sudo docker logs sims-hq` (`-f` to follow) |
| Restart | `sudo docker compose restart hq` |
| Stop | `sudo docker compose down` |
| Health check | `curl -s localhost:5182/api/health` → `{"ok":true}` |
| nginx test + reload | `sudo nginx -t && sudo systemctl reload nginx` |

## Notes / decisions
- Domain is **`.in`** (not `.com`): the wildcard cert is `*.simssoftware.in` and every other
  app is on `.in`; `hq.simssoftware.com` was a stray easyDNS URL-forward.
- **Docker, not RDS**: the box is Amazon Linux 2 (glibc 2.26) which can't run Node 20 natively,
  and Postgres already runs in the `accurate-postgres` container — so HQ is containerized and
  reuses that DB with its own isolated `hq` database + role.
- Node runs **only inside the container** (node:20); the host's Node 16 and the other apps are
  untouched.
