Kanidm out of the box presents itself: its own name, its own mark. A neighbour landing on a login page that belongs to nobody in particular is right to hesitate about typing a password into it. The setup script now sets the vel's display name and logo on both the instance and the portal client. The logo comes from the content repo - the same images/logo.svg site.yaml already uses as the favicon - so the login page and the site are branded from one place, and the branding follows the content rather than this repo. Left alone deliberately: account recovery by email, and easter eggs. Both are decisions, not decoration, and the README says so. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

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 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 podman + podman-compose and openssl (run rootful, i.e. as root, so Caddy can bind 80/443 and Kanidm sees a stable source IP):
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
sudo 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.
Running on kasse (behind the host Caddy)
The vel keeps its own Kanidm and NATS here so it can later lift onto a host
of its own unchanged — on kasse it just runs in isolation, fronted by kasse's
existing host Caddy (which owns 80/443). So the bundled Caddy stays off (it's
behind profiles: [edge]); run the default podman compose up -d --build.
The services publish loopback-only ports for the host Caddy to reach:
- portal →
127.0.0.1:3050 - kanidm →
127.0.0.1:8443(internal self-signed TLS) - nats →
127.0.0.1:4223(kasse's shared platform NATS owns 4222)
Add two host-Caddy site blocks in /etc/caddy/conf.d/, using the vel's .env
hosts (vel.klingenbergbygg.no → :3050 already exists):
<PORTAL_HOST> {
reverse_proxy localhost:3050
}
<ID_HOST> {
reverse_proxy https://localhost:8443 {
transport http { tls_insecure_skip_verify }
}
}
Then sudo systemctl reload caddy, point the content repo's lint-and-reload
reload step at nats://127.0.0.1:4223, and retire the old systemd portal:
sudo systemctl disable --now app@tomtervel-portal.
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.
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. On this host the runner is a host service
(pacman -S gitea-runner, registered against prosjekt.klingenbergbygg.no) —
not an in-compose container — so it reaches NATS on the published
127.0.0.1:4222. Give the content repo's lint-and-reload.yml a reload job
whose runs-on matches that runner's host label, running
nats --server nats://portal:$NATS_PASSWORD@127.0.0.1:4222 pub portal.content.reload "".
Until then, podman compose restart portal picks up new content.
Upgrading portal
Bump PORTAL_RELEASE in .env (a tag of uhhm/portal) and
podman compose up -d --build portal. Keep IRIS_RELEASE in the
content repo's workflow matched to it.
Backups
- Kanidm writes a nightly backup into its volume (
/data/backups, seven kept); copy that directory off the host. - NATS JetStream data is the
nats_datavolume: every record ever submitted and every state change. Snapshot the volume. - Caddy's certificates regenerate; nothing to keep.
What is not here
Mail (a person's reset link is a token you hand them), monitoring, and the vel's current website at tomtervel.no, which stays where it is until the vel points the apex at PORTAL_HOST.
Portal decides what to send - a mail: on a state in the content, or an
invite - and publishes it on this stack's NATS. gdo is what hands it to
a mail server, and it runs here, in the vel's own stack, so the vel's mail
leaves on the vel's own terms.
It has no mail server of its own. It relays through the host's, which on
kasse is Klingenberg Bygg's postfix on port 25, reached from the container
as host.containers.internal. That is the one thing in this stack the vel
borrows, and the one thing that changes if the vel ever moves to a host of
its own: point SMTP_HOST at whatever that host runs.
site.yaml in the content repo needs a mail.from, or portal has nothing
to send from and says so in its log.
Replies are not read yet: JMAP_URL, JMAP_TOKEN and MAIL_REPLY_DOMAIN
turn a reply into a note on the record it answers, and none of them are set
here.
How the login page looks
Out of the box Kanidm presents itself: its own name, its own mark. A
neighbour arriving at a login page that belongs to nobody in particular
is right to hesitate, so kanidm-setup.sh sets the vel's name and mark
on both the instance and the portal client:
kanidm -D idm_admin -H https://$ID_HOST system domain set-displayname "Tomter Vel"
kanidm -D idm_admin -H https://$ID_HOST system domain set-image logo.svg svg
The logo is fetched from the content repo - the same images/logo.svg
that site.yaml uses as the favicon - so the login page and the site
are branded from one place. png, jpg, gif, svg and webp all work.
Two things the setup script deliberately leaves alone, because they are decisions rather than branding:
system domain set-allow-account-recovery truelets someone who has lost their credentials get a reset link by proving one of their own email addresses, instead of asking the board. Worth having for a vel; it is still a door, so it is turned on knowingly or not at all.system domain set-allow-easter-eggs- seasonal icons and birthday surprises. Off in production builds, and this is somebody's vel.
