# Tomter Vel — infrastructure

Everything the vel's own site needs on one host, as containers: Caddy
for TLS, NATS with JetStream for the records, Kanidm for who is who,
and portal, the site itself. The content (pages, forms, desks) lives
in [tomtervel/questions](https://prosjekt.klingenbergbygg.no/tomtervel/questions)
and is fetched from there; this repo owns the host.

```
Internet ──► Caddy (Let's Encrypt)
               ├── PORTAL_HOST ──► portal:3000 ──► NATS (records) + Kanidm (login)
               └── ID_HOST ─────► kanidm:8443 (internal TLS)
```

Today the vel's draft site runs on Klingenberg Bygg's host as
vel.klingenbergbygg.no, sharing that host's Kanidm and NATS. This repo
is the same site on a host of the vel's own, with a Kanidm of its own,
so nothing about the vel's members or records depends on anyone else.

## First start

On a fresh Linux host with docker (compose plugin) and openssl:

```sh
git clone https://prosjekt.klingenbergbygg.no/tomtervel/infrastructure /srv/tomtervel/infrastructure
cd /srv/tomtervel/infrastructure
cp .env.example .env      # set PORTAL_HOST and ID_HOST; DNS must point here
sh bootstrap.sh           # renders configs, makes the internal cert, starts, recovers Kanidm admin
sh kanidm-setup.sh        # logs in, creates the portal client and desk groups, restarts portal
```

`bootstrap.sh` prints the `admin` and `idm_admin` passwords once;
write them down. After `kanidm-setup.sh`, https://PORTAL_HOST serves the
site and https://ID_HOST is the login.

## People and desks

Each group in the content (`qualifies:` under `questions/`) is a
Kanidm group `tomtervel_<group>`, all members of `tomtervel_members`.
Someone in `tomtervel_styret` logs in and sees the board's desk.

```sh
kanidm -D idm_admin -H https://ID_HOST person create kari "Kari Lien"
kanidm -D idm_admin -H https://ID_HOST person update kari --mail kari@example.no
kanidm -D idm_admin -H https://ID_HOST person credential create-reset-token kari
kanidm -D idm_admin -H https://ID_HOST group add-members tomtervel_styret kari
```

Membership is read at login; someone added while logged in logs out
and in again.

## Content changes

A push to tomtervel/questions is linted on push and tells the portal
to reload over NATS. That reload reaches the host it runs on: today
Klingenberg Bygg's. For this host, start the runner profile once with
a registration token from the tomtervel org's Actions settings:

```sh
docker compose --profile runner up -d
```

and give the content repo's `lint-and-reload.yml` a reload job with
`runs-on: tomtervel` that runs
`nats --server nats://portal:$NATS_PASSWORD@127.0.0.1:4222 pub portal.content.reload ""`.
Until then, `docker compose restart portal` picks up new content.

## Upgrading portal

Bump `PORTAL_RELEASE` in `.env` (a tag of uhhm/portal) and
`docker compose up -d --build portal`. Keep `IRIS_RELEASE` in the
content repo's workflow matched to it.

## Backups

- Kanidm writes a nightly backup into its volume (`/data/backups`,
  seven kept); copy that directory off the host.
- NATS JetStream data is the `nats_data` volume: every record ever
  submitted and every state change. Snapshot the volume.
- Caddy's certificates regenerate; nothing to keep.

## What is not here

Mail (a person's reset link is a token you hand them), monitoring, and
the vel's current website at tomtervel.no, which stays where it is
until the vel points the apex at PORTAL_HOST.
