Deployment

This doc describes the public runtime contract for self-hosting Omnigraph. It does not include environment-specific secrets, private infrastructure, or internal deploy automation.

Runtime Modes

Omnigraph supports two broad deployment shapes:

• local directory graphs
• s3:// graphs on AWS S3 or S3-compatible object stores

The server binary and container image expose the same HTTP surface.

The server has a single boot source: a cluster directory (omnigraph-server --cluster <dir | s3://…>), which serves the cluster control plane's applied revision — see cluster-config.md.

Binary Deployment

Build or install:

• omnigraph
• omnigraph-server

On Windows, the binaries are omnigraph.exe and omnigraph-server.exe.

The server boots from a cluster only (RFC-011) — there is no positional <URI> / single-graph boot. Point it at a local cluster directory:

omnigraph-server --cluster ./company-brain --bind 0.0.0.0:8080

Or boot config-free from an object-storage-rooted cluster:

OMNIGRAPH_SERVER_BEARER_TOKEN="change-me" \
AWS_REGION="us-east-1" \
omnigraph-server --cluster s3://my-bucket/clusters/company-brain \
  --bind 0.0.0.0:8080

The server serves every graph in the cluster's applied revision under /graphs/{id}/.... See clusters for authoring and applying a cluster.

Cluster Mode in Containers (AWS, Railway)

A cluster-booted deployment has two shapes since the storage: root:

• Bucket, no volume (preferred for cloud) — the cluster's ledger, catalog, and graph data live under an object-storage root (storage: s3://bucket/prefix in cluster.yaml). The server boots config-free from the bare URI; the container needs no volume at all:

  docker run -d \
    -e OMNIGRAPH_CLUSTER=s3://my-bucket/clusters/company-brain \
    -e AWS_ACCESS_KEY_ID=... -e AWS_SECRET_ACCESS_KEY=... \
    -e OMNIGRAPH_SERVER_BEARER_TOKEN=... \
    -p 8080:8080 <image>
  

  Day-2 runs from any operator checkout of the config repo: omnigraph cluster apply --config ./company-brain (the storage: key routes every stored byte to the bucket), then restart the service. The state lock is genuinely cross-machine on object storage, so CI and operator shells contend safely.

• Volume (file-rooted) — the original shape: the whole cluster directory on a mounted volume. Still fully supported; the container contract:

docker run -d \
  -v /srv/company-brain:/var/lib/omnigraph/cluster \
  -e OMNIGRAPH_CLUSTER=/var/lib/omnigraph/cluster \
  -e OMNIGRAPH_SERVER_BEARER_TOKEN=... \
  -p 8080:8080 <image>

OMNIGRAPH_CLUSTER is the server's only boot source. The image also ships the omnigraph CLI, so the day-2 loop runs in-container:

docker exec -it <container> sh -c \
  'omnigraph cluster apply --as <you> --config /var/lib/omnigraph/cluster'
# then restart the container to pick up the applied state

AWS (ECS/Fargate + EFS)

1. Push the image to ECR (the package.yml workflow builds it).
2. Create an EFS filesystem; mount it in the task definition at /var/lib/omnigraph/cluster.
3. Task environment: OMNIGRAPH_CLUSTER=/var/lib/omnigraph/cluster, bearer tokens via Secrets Manager/SSM into OMNIGRAPH_SERVER_BEARER_TOKENS_JSON (or the --features aws build's native Secrets Manager source).
4. ALB in front for TLS; target the container's 8080 with /healthz checks.
5. Day-2: ECS exec into the task → edit/upload config on the volume → omnigraph cluster apply --as <you> --config /var/lib/omnigraph/cluster → force a new deployment (restart).

For a stateless, volume-free deployment, root the cluster on object storage and boot config-free with OMNIGRAPH_CLUSTER=s3://bucket/clusters/<name> (the bucket-no-volume shape above) — the simplest AWS architecture.

Railway

1. Create a service from the image; attach a volume mounted at /var/lib/omnigraph/cluster.
2. Variables: OMNIGRAPH_CLUSTER=/var/lib/omnigraph/cluster, OMNIGRAPH_SERVER_BEARER_TOKEN=<token>. Railway terminates TLS at its edge and routes to the exposed 8080.
3. Day-2: railway shell (or railway run) → omnigraph cluster apply --as <you> --config /var/lib/omnigraph/cluster → redeploy/restart the service.

Constraints (current honest list)

• No hot reload — applied changes serve on the next restart.
• Single-writer apply — run cluster apply from one place at a time (the state lock enforces this; CI or one operator shell, not both).
• Multi-replica serving off a shared volume (EFS) is documented but unvalidated — boot is lock-free read-only so it should compose, but it is not yet exercised by tests.

One-Command Local RustFS Bootstrap

The easiest local S3-backed deployment path is:

curl -fsSL https://raw.githubusercontent.com/ModernRelay/omnigraph/main/scripts/local-rustfs-bootstrap.sh | bash

The bootstrap:

• starts a local RustFS-backed object store
• creates a bucket and S3-backed Omnigraph graph
• loads the checked-in context fixture
• starts omnigraph-server on 127.0.0.1:8080

Supported behavior:

• downloads the rolling edge binary when one exists for the current platform
• otherwise clones ModernRelay/omnigraph and builds from source
• reuses an existing RustFS container if it is already running

Useful overrides:

• WORKDIR=/path/to/state
• BUCKET=omnigraph-local
• PREFIX=graphs/context
• RESET_REPO=1 to delete an existing partially initialized graph prefix before recreating it
• BIND=127.0.0.1:8080
• RUSTFS_CONTAINER_NAME=omnigraph-rustfs-demo

The bootstrap expects:

• Docker
• curl
• either a matching release asset or a local Rust toolchain plus git

If aws is not installed, the script attempts a user-local AWS CLI install via python3 -m pip. Docker Desktop or another Docker daemon must already be running.

If a previous bootstrap left objects behind under the selected PREFIX but did not finish initializing the graph, rerun with RESET_REPO=1 or choose a new PREFIX.

Container Deployment

Build the image:

docker build -t omnigraph-server:local .

The server boots from a cluster only (RFC-011). Run against a cluster directory on a mounted volume:

docker run --rm -p 8080:8080 \
  -v "$PWD/company-brain:/var/lib/omnigraph/cluster" \
  omnigraph-server:local \
  --cluster /var/lib/omnigraph/cluster --bind 0.0.0.0:8080

Run config-free against an object-storage-rooted cluster:

docker run --rm -p 8080:8080 \
  -e OMNIGRAPH_SERVER_BEARER_TOKEN="change-me" \
  -e AWS_REGION="us-east-1" \
  omnigraph-server:local \
  --cluster s3://my-bucket/clusters/company-brain \
  --bind 0.0.0.0:8080

Container entrypoint env vars

When no positional args are given, the image entrypoint (docker/entrypoint.sh) builds the server command from env vars:

Var	Effect
OMNIGRAPH_CLUSTER	Cluster boot source — a config directory or a storage-root URI, forwarded as --cluster. The only boot source.
OMNIGRAPH_BIND	Listen address (default 0.0.0.0:8080).

Per-graph and server-level Cedar policy come from the cluster's applied revision (authored in cluster.yaml and published with cluster apply), not from a separate config file. The cluster docker shapes — volume vs. config-free object-storage root — are detailed under Cluster Mode in Containers above.

Auth

The server can run unauthenticated for local development only when explicitly started with --unauthenticated or OMNIGRAPH_UNAUTHENTICATED=1. Any shared or internet-facing deployment should set a bearer token source.

Token sources

The server reads bearer tokens from one of three places, in precedence order:

1. AWS Secrets Manager (build with --features aws, see below) — set OMNIGRAPH_SERVER_BEARER_TOKENS_AWS_SECRET to the secret ID or ARN.
2. JSON file or env — set one of:
   • OMNIGRAPH_SERVER_BEARER_TOKENS_FILE — path to a JSON {"actor": "token", ...} file.
   • OMNIGRAPH_SERVER_BEARER_TOKENS_JSON — the JSON literal inline.
3. Single-token env — OMNIGRAPH_SERVER_BEARER_TOKEN (assigns the implicit actor default).

Tokens are hashed with SHA-256 immediately on ingest; plaintext does not persist in process memory after startup.

The health endpoint /healthz remains suitable for load balancer health checks and is never gated.

Build Variants

The server binary ships in two flavors:

Variant	Command	Contents
Default (on-prem / local dev)	cargo build --release	Core server, no AWS SDK
AWS	cargo build --release --features aws	Adds AWS Secrets Manager backend for bearer tokens

Tagged release archives contain the default omnigraph and omnigraph-server binaries on macOS / Linux, and omnigraph.exe plus omnigraph-server.exe on Windows. AWS-enabled server binaries are built from source with cargo build --release --features aws -p omnigraph-server when needed.

The AWS build adds ~150 transitive deps and ~30-60s of first-build compile time. Default builds don't pay that cost.

AWS Secrets Manager

When the binary is built with --features aws, set OMNIGRAPH_SERVER_BEARER_TOKENS_AWS_SECRET to the ARN or name of a Secrets Manager secret whose SecretString is a JSON object of {"actor_id": "token", ...}:

omnigraph-server-aws s3://my-bucket/graphs/example ...
  # Environment:
  # OMNIGRAPH_SERVER_BEARER_TOKENS_AWS_SECRET=arn:aws:secretsmanager:us-east-1:123456789012:secret:omnigraph-tokens-AbCdEf

Credentials are resolved via the AWS default chain (env vars, shared config, IMDSv2 instance role, ECS task role) — no explicit credential plumbing is needed when running under an IAM instance role on EC2/ECS/EKS.

The IAM role must permit secretsmanager:GetSecretValue on the referenced secret.

Setting the env var without building with --features aws is a hard error with a rebuild instruction — it does not silently fall back to the env/file source.

S3-Compatible Storage

For S3-compatible backends such as RustFS or MinIO, set the usual AWS SDK environment variables:

• AWS_ACCESS_KEY_ID
• AWS_SECRET_ACCESS_KEY
• AWS_REGION
• optional AWS_ENDPOINT_URL
• optional AWS_ENDPOINT_URL_S3
• optional AWS_ALLOW_HTTP=true
• optional AWS_S3_FORCE_PATH_STYLE=true
