# bokf — running in Docker

Status: Draft 0.1 · 2026-09-17 · License: GPL-3.0-or-later

Two roles:

- **host** — runs Docker + the compose plugin only. No toolchain, no registry.
- **dev machine** — has the source and builds the image; deploys with
  `scripts/deploy.sh` over SSH.

There is no forge or registry in this flow. Releases are git tags, images are
transferred directly with `docker save | ssh docker load`.

State lives in two bind mounts next to `compose.yaml`:

| Host path | Container | Contents |
|---|---|---|
| `var/db` | `/var/lib/bokfd` | SQLite database, `backup/`, `export/`, `certs/` |
| `var/run` | `/run/bokfd` | Unix socket (mode 0660, owned by uid 10001) |

The `bokfd` service publishes port 8788 for the TLS listener; the `certs`
sidecar renews the certificate with lego via INWX DNS-01. Plain TCP stays
off (loopback-only if enabled); the Unix socket is for clients on the host.

The database is a single SQLite file. Back up with `backup.snapshot`
(`VACUUM INTO`) and point restic at `var/db/backup` — never at the live file.

## First run

On the dev machine, put the SSH target in `.env`:

```sh
cp .env.example .env
# set BOKF_HOST=user@host and BOKF_REMOTE_DIR=/srv/bokf
scripts/deploy.sh v0.1.0
```

The first run stops after shipping the image and compose.yaml, and prints the
one-time init command. Run it on the host:

```sh
cd /srv/bokf
docker compose run --rm -e BOKFD_PASSWORD='<admin-password>' bokfd init
docker compose up -d
docker compose ps          # wait for "healthy"
```

`init` creates the admin user and must run before the first `up`; it refuses
to touch an already initialized database. Subsequent `scripts/deploy.sh`
runs update the image, tag and compose file, restart the daemon and wait for
the healthcheck.

## Deploying upgrades

```sh
git tag v0.1.1
scripts/deploy.sh            # tag defaults to git describe
scripts/deploy.sh v0.1.1     # or pass one explicitly
```

The script:

1. `make` + `make test` on the dev machine,
2. builds `bokf:<tag>`: locally and ships it with `docker save | gzip | ssh
   docker load`, or — when the host runs a different CPU architecture —
   builds it natively on the host from a source tar,
3. copies `compose.yaml` and writes `BOKF_IMAGE`/`BOKF_TAG` into the host's
   `.env` (other keys are preserved),
4. `docker compose up -d --no-build`, then polls the container healthcheck,
5. on failure, puts the previous `BOKF_TAG` back and rolls back to the image
   that is still loaded on the host.

Cross-architecture builds are automatic: `uname -m` is compared over SSH and
a mismatch switches to a remote build. Override with `BOKF_BUILD=local` or
`BOKF_BUILD=remote` (also settable in `.env`). A remote build pulls the
Debian base image inside a container, so the host needs outbound network
access but still no toolchain.

Tags are `git describe` output unless passed. Tag releases (`v*`) so rollback
and support have meaningful versions. The rollback image must still exist on
the host; don't prune before the new version has proven itself.

Manual rollback — set `BOKF_TAG` on the host and restart:

```sh
cd /srv/bokf
sed -i 's/^BOKF_TAG=.*/BOKF_TAG=v0.1.0/' .env
docker compose up -d --no-build
```

## Optional: a bare repository on the host

For an off-machine copy of the source and an optional auto-deploy hook:

```sh
ssh host 'git init --bare /srv/git/bokf.git'
git remote add host ssh://host/srv/git/bokf.git
git push host main
```

If the host also has the toolchain and a checkout whose origin is that bare
repo, `deploy/post-receive.sample` can build, test and restart on every push
to `main`. The normal `scripts/deploy.sh` flow does not need any of this.

## Clients

Run clients inside the container — no host toolchain needed:

```sh
docker compose exec bokfd bokftui                    # interactive TUI
docker compose exec -e BOKFD_PASSWORD='<pw>' bokfd \
    bokfctl --user admin fiscal_year.list
```

The clients honor `BOKFD_SOCKET`; a host-installed client can also point at
`var/run/bokfd.sock`, but that file is owned by uid 10001, so the host user
must be in that group (or use `sudo`).

The TUI remembers the server and user (never the password) in
`$XDG_CONFIG_HOME/bokf/tui.conf` (`~/.config/bokf/tui.conf`), written after
a successful login. Precedence: `--socket`/`--user`, then `BOKFD_SOCKET`/
`BOKFD_USER`, then that file.

For credentials from a Bitwarden/Vaultwarden item, use the user-space
launcher — nothing runs as root:

```sh
install -m 755 scripts/bokftui-bw ~/.local/bin/bokftui-bw
BOKF_BW_ITEM=bokf bokftui-bw
```

`bokftui-bw` works with `rbw` (its agent keeps the vault unlocked for the
session) or the official Bitwarden CLI `bw`, where the session key is cached
in `~/.cache/bokf/bw-session` (mode 0600) so the master password is only
asked when the session expires. On Node < 19 the launcher adds
`--experimental-global-webcrypto` when the SDK's WASM crypto needs it. It reads the item's password, or the custom
field named by `BOKF_BW_FIELD`, and execs the TUI.

Prefer a scoped, revocable API token over the account password: create one
on the host, put it in a custom field (e.g. `token`) of the item, then:

```sh
docker compose exec -e BOKFD_PASSWORD='<pw>' bokfd \
    bokfctl --user admin --org 1 token.create \
    '{"label":"tui-laptop","scopes":["read","write","admin"]}'

BOKF_BW_KIND=token BOKF_BW_FIELD=token BOKF_BW_ITEM=bokf bokftui-bw
```

With `BOKFD_TOKEN` set the TUI logs in without showing the login screen.
Revoke the token with `token.revoke` when a machine goes away.

## TLS and external users

Put the ACME DNS credentials in the host's `.env` once (they are never
committed):

```sh
LEGO_DOMAIN=bokf.makandra.eu
LEGO_EMAIL=anders@makandra.eu
INWX_USERNAME=...
INWX_PASSWORD=...
```

Forward port 8788 on the router to the host. The `certs` sidecar obtains and
renews the certificate into `var/db/certs/certificates/`; `bokfd` reloads it
in place. On the very first `up`, `bokfd` may restart a few times until the
certificate exists — check `docker compose logs certs`.

Clients outside the LAN connect with the DNS name:

```sh
export BOKFD_SOCKET=tls:bokf.makandra.eu:8788
bokftui
```

No CA override is needed with a public ACME certificate (the system trust
store suffices); `BOKFD_TLS_CA=/path/ca.pem` exists for private CAs.

To invite someone, create an account and give it only the role and org it
needs — no VPN, no SSH:

```sh
docker compose exec -e BOKFD_PASSWORD='<owner-pw>' bokfd \
    bokfctl --user admin user.create '{"username":"revisor", ...}'
docker compose exec -e BOKFD_PASSWORD='<owner-pw>' bokfd \
    bokfctl --user admin org.member_add '{"org":1,"username":"revisor","role":"viewer"}'
```

Agents use `token.create` instead of a password; tokens are scoped and
revocable. Only the TLS port is forwarded, and every command still requires
authentication (`meta` and `health` excepted).

## Mock company

```sh
docker compose exec -e BOKFD_PASSWORD='<pw>' bokfd \
    bokfctl --user admin org.create \
    '{"name":"Mock AB","org_nr":"556000-0000","fiscal_year_start_month":1}'
```

Develop against this org; agents get their own API token
(`bokfctl token.create ...`, shown once).

## Backup and restore

`backup.snapshot` makes a consistent copy of the live WAL database with
`VACUUM INTO`; the result lands in `var/db/backup/` as
`bokfd-<timestamp>.db` (the response carries its SHA-256). Interactive:

```sh
docker compose exec -e BOKFD_PASSWORD='<pw>' bokfd \
    bokfctl --user admin backup.snapshot
ls var/db/backup
```

For unattended backups (restic, cron) use an admin-scoped token instead of
the password, created once:

```sh
docker compose exec -e BOKFD_PASSWORD='<pw>' bokfd \
    bokfctl --user admin token.create '{"label":"backup","scopes":["admin"]}'
# store the token (shown once) in a root-only file, e.g. /etc/bokf/bokfd-backup.env:
#   BOKFD_TOKEN=bokf_...
```

Then, before every restic run: take a snapshot through the daemon and let
restic read only the snapshots — never the live database:

```sh
set -a
. /etc/bokf/bokfd-backup.env
set +a
docker compose --project-directory /mnt/data/bokf exec -T -e BOKFD_TOKEN \
    bokfd bokfctl backup.snapshot >/dev/null
find /mnt/data/bokf/var/db/backup -name 'bokfd-*.db' -mtime +14 -delete
restic backup --exclude='/mnt/data/bokf/var/db/bokfd.db*' \
    --exclude='/mnt/data/bokf/var/run' /mnt/data/bokf
```

The WAL and shared-memory files (`bokfd.db-wal`, `bokfd.db-shm`) must be
excluded together with the main file; an inconsistent copy of a live SQLite
database is worse than no backup.

Restore:

```sh
docker compose stop
cp var/db/backup/<snapshot>.db var/db/bokfd.db
rm -f var/db/bokfd.db-wal var/db/bokfd.db-shm
docker compose start
```

To replace the mock with a real database from another host, restore its
snapshot the same way (same or newer bokf version; older schemas migrate
forward). SIE import is the alternative once the importer's CRLF/`#RAR`
fixes land.

## Local development

```sh
make -j"$(nproc)" && make test     # no Docker required
docker compose up --build          # same image, local var/ data dir
```

`scripts/deploy.sh` always runs the tests before shipping. `var/`, `.env`,
`*.db` and `*.se` are gitignored — real books never enter the repository.
