tajniak81andClaude Opus 5 fe1e314df9 The store comes apart into the four roles it always had
`weed server -s3` was never one thing. Master, volume, filer and the S3
gateway ran as four goroutines under one process, on one volume, sharing one
fate. Splitting them into four containers changes nothing a client can see —
the same bucket answers on the same port — but it makes three things possible
that were not: the SeaweedFS admin UI, which wants a cluster to look at; a
restart or an upgrade of one role without the others; and, eventually, a second
volume server somewhere else. A fifth container carries the panel itself.

The single-process files stay exactly as they were. These are `.split.` twins
beside them, four in all, one per folder per shape, each with the .env example
of the same name that both READMEs already promise.

Identities are the part that could not simply be copied across. SeaweedFS picks
its credentials from one source, in order: an -s3.config file, the filer's IAM
store, then AWS_ACCESS_KEY_ID and its secret — and a higher source replaces a
lower one rather than adding to it. The existing files use the env pair, which
is fine precisely because nothing else writes identities there. Hand somebody a
panel that can, and the first user they create lands in the filer's store, the
store outranks the environment, and PocketBase's key stops existing — with the
first failed upload as the notification. So the gateway here is started with no
config file and no AWS_* at all, and the init container seeds PocketBase's
identity into the filer's store instead: the same store the panel writes. One
source of truth, PocketBase's key sitting in Object Store → Users beside every
other, keys minted there picked up without a restart, and a rotated
PB_S3_SECRET re-applied in place on the next boot rather than added as a second
identity.

That seeding is now allowed to fail. The bucket-create it grew out of was
best-effort — `|| true`, on the reasoning that the API Server's own S3 check
would report a gateway that was genuinely unreachable. That reasoning does not
survive the change: a gateway whose IAM store is empty does not refuse anyone,
it serves everyone, and the bucket would be wide open rather than unreachable.
So the step ends by grepping the configuration back for the access key, the
gateway waits on it completing successfully, and a seed that did not land stops
the stack instead of opening it.

The prod files publish the gateway and the panel, both on loopback, and nothing
else. Port 8080 on the volume server hands out file content by file id with no
authentication of any kind — the S3 credentials have no bearing on it — so
publishing it would publish every attachment in the stack, and the panel shows
what that port and the master's would. The panel's own password is required
rather than defaulted, because weed serves it with authentication switched off
entirely when it is empty, and a page that mints bucket credentials is the
bucket. It is passed as WEED_ADMIN_PASSWORD rather than a flag so it stays off
the process command line, and SEAWEED_ADMIN_BIND is the knob a remote host
needs, named after PB_BIND and API_BIND for the same reason.

Master, volume and filer share one /data mount rather than taking three of
their own. That is precisely the layout `weed server -dir=/data` writes — the
master's raft state, the volume's .dat and .idx, the filer's filerldb2, no two
of them naming the same file — so a stack can move between the single-process
file and its twin in either direction with nothing to migrate. A second volume
server would need its own, and the files say so where somebody would go looking.

The dev files map the volume server to 8081 on the host: 8080 there is already
the API Server, and in the all-in-one it is the API Server inside the image.

Unexercised: written on a machine without Docker, so none of the four has been
brought up. Every flag, health path and env name was read out of the pinned
4.45 source rather than recalled — -mdir, -volumeSizeLimitMB, -defaultStoreDir,
-max, admin's -master and -dataDir and WEED_ADMIN_*, the filer's and gateway's
/healthz, the panel's unauthenticated /health — and the four files were parsed,
interpolated against their examples, and checked for duplicate host ports. A
`docker compose config` on the target host is still the first thing to run.

DriverVault — Docker AIO (all-in-one image)

PocketBase + API Server + Web App in a single container, supervised by supervisord with nginx serving the SPA and proxying /api/ to the API Server on localhost. One image, one volume set, no compose network — the simplest way to stand DriverVault up on a single host.

Prefer the three-container stack in ../Docker when you want to scale, upgrade or restart the pieces independently.

:80   nginx ─► SPA, and /api/ ─► API Server on 127.0.0.1:8080 ─► PocketBase on :8070
File Use
Dockerfile the all-in-one image (build context must be the repo root)
docker-compose.yml builds from source — for development and local testing
docker-compose.prod.yml pulls the prebuilt image from the registry
.env.example / .env.prod.example copy to .env for the matching compose file

Run it

cd "Docker-AIO"
cp .env.example .env        # then edit — PB_ADMIN_* have no safe defaults
docker compose up -d --build

Production, from the registry:

cp .env.prod.example .env   # then edit
docker compose -f docker-compose.prod.yml pull
docker compose -f docker-compose.prod.yml up -d

Then: web app on http://host:8090/, the API Server's superadmin panel on http://host:8080/, PocketBase admin on http://host:8070/_/.

Note the port mapping: inside the container the web app is on 80, published as WEB_PORT (8090 by default) to line up with the other deployment.

Building by hand

The build context must be the repo root so the Dockerfile can reach both API Server/ and Web App/:

docker build -f "Docker-AIO/Dockerfile" -t drivervault-aio .

Build args: VITE_API_BASE (leave empty so the bundle uses same-origin /api) and PB_VERSION, which the Dockerfile already pins. Override it to build a different PocketBase; set it to an empty string to resolve the latest release at build time instead.

First boot

Identical to the multi-container stack, and idempotent:

  1. PocketBase upserts its superuser from PB_ADMIN_EMAIL / PB_ADMIN_PASSWORD.
  2. The API Server waits for PocketBase to report healthy, then creates any missing collections, reconciles existing ones, and creates the first app superadmin from DRIVERVAULT_SUPERADMIN_EMAIL / _PASSWORD.

Leave PB_BOOTSTRAP at true, including across upgrades. A release can add collections or fields the server needs, and a stack that skipped the bootstrap never gets them. The API Server self-heals exactly one thing — app_settings, the collection holding the plugin settings, which it creates on demand because it cannot serve the plugin panel without it. Every other schema change still depends on this flag, so turn it off only for a database you know already matches the release you are running.

Volumes

Volume Holds
/pb/pb_data the PocketBase SQLite database and uploaded files — everything that persists

One volume, because the API Server keeps no state on disk. Plugin enable-state and global config live in the database like the rest of the settings, so backing up this one path backs up the whole image. It defaults to a Docker-managed named volume; set PB_DATA to an absolute host path in the prod file for a bind mount.

One thing does not persist: the API Server panel's Settings → PocketBase and Settings → Web App screens apply immediately but only for the life of the container. Set the corresponding environment variables to change them permanently.

File storage (SeaweedFS / S3)

Uploaded files — document scans, service and refill receipts, workshop invoices, part photos — live inside pb_data by default, next to the database. Two further compose files put them in an S3 bucket instead, so the blobs and the database can be sized, backed up and moved independently. Nothing else changes: an attachment has always been fetched through the API Server (GET /api/service-records/{id}/file), never from a storage URL, so the Web App, the phone app and the Home Assistant plugin cannot tell the difference.

Each shape is one self-contained compose file — nothing to layer, nothing to remember — with an .env example of the same name:

Shape From the registry From source
Local storage — the default, unchanged docker-compose.prod.yml docker-compose.yml
SeaweedFS beside the image docker-compose.prod.seaweedfs.yml docker-compose.seaweedfs.yml
SeaweedFS, split into its roles docker-compose.prod.seaweedfs.split.yml docker-compose.seaweedfs.split.yml
An S3 endpoint elsewhere docker-compose.prod.s3.yml docker-compose.s3.yml

So docker-compose.prod.seaweedfs.yml is configured from .env.prod.seaweedfs.example, docker-compose.s3.yml from .env.s3.example, and so on:

cp .env.prod.seaweedfs.example .env    # then edit it — PB_S3_* have no defaults
docker compose -f docker-compose.prod.seaweedfs.yml pull
docker compose -f docker-compose.prod.seaweedfs.yml up -d

Set PB_S3_ACCESS_KEY and PB_S3_SECRET first — both storage files refuse to start without them. The SeaweedFS ones run the gateway as a second container (master, volume, filer and S3 in one process, on its own seaweed_data volume) rather than a fourth process under supervisord: keeping the object store in this image, on the volume the files are being moved off, would defeat the point and would mean rebuilding. They also run a one-shot seaweedfs-init that creates the bucket, because PocketBase never issues a CreateBucket of its own. The external-S3 ones add no containers at all: set PB_S3_ENDPOINT, and create the bucket yourself.

Split SeaweedFS

weed server -s3 runs master, volume, filer and gateway as four goroutines in one process. The .split. files run them as four containers beside the all-in-one, plus a fifth: the SeaweedFS admin UI on port 23646, where the cluster can be inspected and — under Object Store → Users — further S3 identities minted and revoked. Split also gets you per-role restarts and upgrades, per-role Prometheus metrics, and room to add a second volume server later. Still none of them inside the image, for the reason above.

Identities work differently there, and it matters. SeaweedFS reads credentials from, in descending priority: an -s3.config file, the filer's IAM store, then AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY — and a higher source replaces a lower one rather than adding to it. The single-gateway files use the env vars, which is why nothing else may write identities there: the first user added in a panel would displace PocketBase's key. So in the split files seaweedfs-init seeds PocketBase's identity into the filer's store instead — the same store the admin UI writes — and the gateway runs with no config file at all. One source of truth, PocketBase's key visible in the panel beside every other, and new keys picked up without a restart. Rotating PB_S3_SECRET in .env and restarting updates that identity in place.

Set SEAWEED_ADMIN_PASSWORD: weed admin serves the panel with no authentication when it is empty, and a panel that can mint bucket credentials is the bucket. In the prod file it is bound to loopback like SEAWEED_S3_BIND — it is storage plumbing, not one of the app's own panels — so a remote host needs SEAWEED_ADMIN_BIND=0.0.0.0 behind a reverse proxy. That file publishes nothing for master, volume and filer: the volume server serves file content by id with no authentication of any kind, and the admin UI already shows what those ports would.

Switching between docker-compose.seaweedfs.yml and its .split. twin needs no migration: master, volume and filer share one /data mount, which is exactly the layout weed server -dir=/data writes.

On every boot the API Server's bootstrap writes PocketBase's Files storage settings from those variables, then asks PocketBase to prove it can reach the bucket. Watch for it in the log:

[api] bootstrap: ✓ file storage → S3 (drivervault at http://seaweedfs:8333)
[api] bootstrap: ✓ S3 storage reachable

A boot that finds the settings already correct logs • file storage already on S3 and writes nothing.

Two things to know before turning it on:

  • Existing files are not migrated. PocketBase copies nothing when the setting flips, so attachments uploaded before the switch stop resolving. Copy pb_data/storage/<collectionId>/<recordId>/<file> into the bucket root, keeping that layout, before enabling it — or start from a stack with no attachments.
  • Going back to the plain compose file is not an off switch. It leaves PocketBase pointed at the bucket, deliberately: files already written there are reachable only while it is. Move them back and turn it off in PocketBase's own admin UI. For the same reason a rotation of PB_S3_SECRET alone is invisible to the bootstrap — PocketBase masks the stored secret on read — so change another PB_S3_* value alongside it, or set it in the admin UI.

Charger control (OCPP)

Chargers in own/proxy mode dial in to /ocpp/{serial} on the API Server port (8080) — not through nginx — authenticating with a per-charger control token in an OCPP Basic-auth header. Because a plaintext ws:// would expose that token, OCPP_REQUIRE_TLS defaults to true.

This image serves plain HTTP, so charger control needs TLS terminated in front of it, with OCPP_PUBLIC_URL set to the public wss:// base. Only drop OCPP_REQUIRE_TLS on a trusted network.

Caveats

  • PocketBase and the API Server run as the unprivileged app user; only nginx stays root, because it binds port 80. A crash of supervisord still takes all three services down together — that is the trade for the simplicity.
  • Logs from all three processes are interleaved on the container's stdout/stderr (docker logs drivervault-aio).
  • PB_VERSION is pinned in the Dockerfile so two builds of the same source agree. Setting it to an empty string restores the old behaviour of resolving the latest release at build time, which also costs an unauthenticated GitHub API call and is subject to that 60/hour per-IP rate limit.
  • The container reports health once all three processes answer their probes, so a wedged component shows up in docker ps rather than looking up.
