oxynote/docker/prod

Oxynote production image

One container running the whole product: Caddy (front door), the web app (Nuxt SSR), the core API server, the auth/realtime service and a PostgreSQL database, supervised by a small launcher. Nothing outside the image is required: an external PostgreSQL can take the embedded one's place, and Valkey, an S3-compatible object store, an SMTP relay and changedetection.io are optional and external. Full-text search is built in: core keeps its index on the data volume and rebuilds it from PostgreSQL when it is missing, so the image runs as a single instance.

Quick start

cp docker/prod/docker-compose.example.yaml my-deployment.yaml
# replace every change-me value; for a real domain set OXYNOTE_PUBLIC_URL
docker compose -f my-deployment.yaml up -d

From a repository checkout, make prod-run builds the image locally (goreleaser builds the core binary first — a bare docker build is not supported) and runs this example on http://localhost:8080, with docker-compose.local.yaml layered on top to add an email sender: a mailpit that shows the delivered mail at http://localhost:8025. make prod-run-no-email runs the example without that override, as a deployment without an email sender. make prod-stop stops either.

The image serves plain HTTP on port 8080 and assumes it is reached at http://localhost:8080 unless told otherwise, so publish the container as 8080:8080 for a local run. For a real domain, put a TLS-terminating proxy in front and set OXYNOTE_PUBLIC_URL to the public https:// origin.

Configuration

Everything is configured through flat OXYNOTE_* variables. Setting any other OXYNOTE_-prefixed variable (a typo, or a component-internal name) fails the boot with an error naming it.

Database

Variable	Meaning
OXYNOTE_DB_DSN	an external PostgreSQL, e.g. postgresql://user:pass@host/db?sslmode=require. Unset, the image runs its own PostgreSQL 18 with its data under /oxynote/data/postgres; set, the embedded one never starts. One database serves the whole product; migrations run automatically at boot.

Public address

Variable	Meaning
OXYNOTE_PUBLIC_URL	the origin users open in the browser, e.g. https://notes.example.com. Scheme + host only — every public URL, the cookie domain, and the CORS rules derive from it. Defaults to http://localhost:8080, which is right only while the container's port 8080 is published as host port 8080; set it for a domain or any other host port.

Optional features

Each feature is keyed on one variable; leaving it unset disables the feature cleanly. An incomplete group fails the boot with the missing name.

Group	Variables
Valkey/Redis	OXYNOTE_VALKEY_DSN (redis[s]://[user:pass@]host:port[/db], credentials supported). Without it the assistant keeps its conversations in the core process and sessions are not cached outside Postgres.
Object storage	OXYNOTE_OBJECT_STORAGE_DSN — an S3-compatible store as one URL: http(s)://ACCESS_KEY:SECRET_KEY@host:port/bucket[?region=...] (the bucket defaults to oxynote and is created if missing). Without it uploaded images are kept on the data volume, which is the right choice for a single-node deployment.
Email	OXYNOTE_SMTP_DSN (smtp[s]://[user:pass@]host:port[?tls=none|starttls|tls]), OXYNOTE_EMAIL_FROM_ADDRESS. Without it the product runs without email, as described below.
GitHub App	OXYNOTE_GITHUB_APP_ID, OXYNOTE_GITHUB_APP_SLUG, OXYNOTE_GITHUB_APP_SIGNATURE_SECRET; mount the app's private key at /oxynote/github/private-key.pem
Slack app	OXYNOTE_SLACK_APP_CLIENT_ID, OXYNOTE_SLACK_APP_CLIENT_SECRET, OXYNOTE_SLACK_APP_SIGNATURE_SECRET
Social login	OXYNOTE_SOCIAL_LOGIN_{GITHUB,GOOGLE,SLACK}_CLIENT_ID + _CLIENT_SECRET (both halves per provider)
AI assistant	OXYNOTE_AI_ASSISTANT_PROVIDER (anthropic, openai, google, ollama, openrouter) plus the vendor's credentials, detailed in docs/ai.md: OXYNOTE_AI_ASSISTANT_API_KEY, _MODEL, _BASE_URL, _MAX_TOKENS, _REQUEST_TIMEOUT, _SUMMARY_MODEL, _AZURE_API_VERSION, _BEDROCK_{REGION,ACCESS_KEY,SECRET_ACCESS_KEY,SESSION_TOKEN}, _VERTEX_{PROJECT_ID,REGION,SERVICE_ACCOUNT_JSON}
URL watching	OXYNOTE_CHANGE_DETECTION_URL, OXYNOTE_CHANGE_DETECTION_API_KEY (a changedetection.io instance)

Without an email sender

Without OXYNOTE_SMTP_DSN nothing is emailed, and the flows that would wait for a link work without one:

• Signup skips email verification and goes straight to workspace creation.
• Invitations are still created, but their links have to be passed on by hand. Workspace settings offer Copy invitation link on each pending invitation, and show a notice about it.
• Changing the email address or deleting the account asks for the current password. Accounts that sign in only through a social login have no password, so they can do neither.
• Password reset is switched off, and there is no other way to recover a forgotten password. The login page tells users to contact their administrator.

Setting OXYNOTE_SMTP_DSN later brings the email flows back after a restart. Accounts created in the meantime have unverified addresses, so their next login sends a verification link first.

Tuning

OXYNOTE_MAX_ORGANIZATIONS, OXYNOTE_MAX_ORGANIZATION_MEMBERS, OXYNOTE_RATE_LIMIT_DISABLED (true/false; the built-in limiter buckets by client IP — disable it behind a proxy that hides the original IP and rate limit there instead), OXYNOTE_MAX_DOCUMENT_HISTORY_ENTRIES, OXYNOTE_DOCUMENT_HISTORY_RETENTION (Go duration, e.g. 2160h), OXYNOTE_LOG_LEVEL (DEBUG/INFO/WARN/ERROR; the floor for both core and auth-realtime, WARN by default, so the container logs carry the exceptions rather than the traffic), OXYNOTE_TERMS_OF_SERVICE_URL, OXYNOTE_PRIVACY_POLICY_URL.

Secrets and the data volume

Internal secrets (session signing, data-source credential encryption, the GitHub/Slack install-state keys, the embedded database's password) are generated on first boot and stored under /oxynote/data/secrets/ with owner-only permissions — keep that volume.

• Unless OXYNOTE_DB_DSN is set, the database lives there too, under /oxynote/data/postgres, and so does every document. Back it up with the pg_dump the image ships:

  docker compose exec -T oxynote sh -c 'PGPASSWORD="$(cat /oxynote/data/secrets/database-password)" \
    /usr/libexec/postgresql18/pg_dump -h /tmp/postgresql -U oxynote oxynote' > oxynote.sql
  

• Unless an object store is configured, every uploaded image lives there too, under /oxynote/data/object-storage.

• Losing the volume signs everyone out, permanently orphans every stored data-source credential, and takes the uploaded images, and the embedded database, with it.

• Two advanced overrides exist for migrating an existing deployment in: OXYNOTE_AUTH_SECRET (session/token signing) and OXYNOTE_DATA_SOURCE_ENCRYPTION_KEYS (comma-separated, newest first, each the standard base64 of exactly 32 bytes). An override always wins and is never written to disk.

• To rotate the data-source encryption key, read the current key from secrets/data-source-encryption-key on the volume (or from your existing override), set OXYNOTE_DATA_SOURCE_ENCRYPTION_KEYS to <new key>,<current key> and restart: core re-encrypts every stored credential under the new key at boot and logs how many it moved. On a later restart set the override to <new key> alone. The override is never written back, so from then on it stays set; to return to the generated file instead, write <new key> into secrets/data-source-encryption-key before dropping the override, or core boots with only the retired key and reads no credential.

Security model

• Only port 8080 (Caddy) is reachable. Core, auth-realtime, and the web server bind the container's loopback, so their unauthenticated internal surfaces cannot be reached from any network — the launcher verifies this at boot and refuses to serve otherwise. Caddy additionally blocks the internal paths (/core/api/x/*, /auth-realtime/api/internal/*) at the front door.
• The embedded PostgreSQL listens on a unix socket inside the container and on no TCP port. Every connection needs the app role's generated password, and that role owns the product's database and nothing else, so a data source pointed at the socket gets nowhere.
• Keep the backing services on a private network reachable only by this container, and where Valkey is used enable its authentication (requirepass + a credentialed OXYNOTE_VALKEY_DSN).
• The image runs as a non-root user and writes only to /oxynote/data and /tmp, so it supports a read-only root filesystem (docker run --read-only --tmpfs /tmp, Kubernetes readOnlyRootFilesystem: true).

Error reporting

Official images carry Sentry DSNs baked in at build time, so crashes in self-hosted deployments can reach the Oxynote team. A DSN is a write-only ingest address: it lets the image send events, never read them, and nothing can be queried through it.

What an event carries is the crash itself — the error, its stack trace, the component and release, the container's hostname, and the request path that failed. Every component runs with personal-data collection off, so no cookies, request bodies or client IPs are attached, and no document content is sent. An error message can still quote what it was working on, so treat the reports as diagnostic data leaving your deployment, and switch them off with OXYNOTE_CRASH_REPORTING_DISABLED=true if that is not acceptable. Locally built images carry no DSNs and report nothing.

Bundled software

The image bundles the Caddy web server unmodified (Apache-2.0) and tini (MIT) as the init process. Both are downloaded at pinned versions and checksum-verified during the image build, and both licenses ship under /oxynote/licenses/. Node.js comes from the pinned Alpine base (the v24 line, with full ICU locale data), and so does PostgreSQL 18.

The image is published for linux/amd64 and linux/arm64; a pull fetches the variant for the machine's architecture.
