* fix(cluster): stop cluster-apply crash-loops from the recovery-sidecar trap A `cluster apply` carrying a schema change against a graph that has non-main branches, or an unsupported "needs backfill" migration, armed a recovery sidecar *before* calling the engine, then left it behind when the engine rejected the apply pre-movement. The server refuses to boot while any sidecar is pending, and re-running apply re-armed a fresh sidecar — an unescapable crash loop. None of the engine rejections are bugs; the trap is in the apply/serve choreography. Three coordinated changes: 1. Preview before arming the sidecar. `cluster apply` now runs `preview_schema_apply_with_options` before `write_recovery_sidecar`, so parser/planner rejections (non-main branches, unsupported plan) fail loudly without leaving recovery work behind. The post-preview engine error path now deletes the sidecar when the live schema still matches the recorded digest (nothing moved), and keeps it only on real mid-movement failure — both branches covered by new engine-failpoint tests (cluster failpoints now enable omnigraph/failpoints). 2. Per-graph quarantine at serve time instead of whole-cluster refusal. A graph-attributed pending sidecar, an unopenable graph root, a query parse failure, or an unresolvable embedding provider now quarantines just that graph (logged loudly at every boot layer) while healthy graphs serve; `/graphs` lists only ready graphs and quarantined routes 404. Cluster-global problems (missing/unreadable state, malformed or unattributable sidecars, shared-catalog or cluster-policy errors, zero healthy graphs) stay fail-fast. `--require-all-graphs` / OMNIGRAPH_REQUIRE_ALL_GRAPHS=1 restores all-or-nothing boot. 3. Backfill embedding-provider profile metadata on apply. Mirrors the existing policy-binding backfill: a pre-5A ledger missing `embedding_profile` is now detected as a metadata-only change and backfilled by a no-op apply, instead of bricking serve with `embedding_provider_profile_missing` forever. Tests: trap (no sidecar after a rejected apply), both digest-cleanup branches, per-graph quarantine (cluster + server), embedding backfill.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(cluster): surface sidecar-cleanup failures; document severity promotion Address Greptile review on PR #284: - The pre-movement sidecar cleanup fast-path discarded `delete_object`'s result, so a transient delete failure left the graph quarantined with no signal. Add `try_delete_object` (Result-returning) and emit a `recovery_sidecar_cleanup_failed` warning diagnostic on failure; the fire-and-forget `delete_object` now delegates to it. - Document why the serve-time loop promotes every `list_recovery_sidecars` diagnostic to a cluster-fatal error (the listing only emits genuine read/parse/version failures, as warnings, whose blast radius serving cannot prove) and note the promote-by-code path if that ever changes.

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:
omnigraphomnigraph-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/prefixincluster.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(thestorage: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)
- Push the image to ECR (the
package.ymlworkflow builds it). - Create an EFS filesystem; mount it in the task definition at
/var/lib/omnigraph/cluster. - Task environment:
OMNIGRAPH_CLUSTER=/var/lib/omnigraph/cluster, bearer tokens via Secrets Manager/SSM intoOMNIGRAPH_SERVER_BEARER_TOKENS_JSON(or the--features awsbuild's native Secrets Manager source). - ALB in front for TLS; target the container's 8080 with
/healthzchecks. - 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
- Create a service from the image; attach a volume mounted at
/var/lib/omnigraph/cluster. - Variables:
OMNIGRAPH_CLUSTER=/var/lib/omnigraph/cluster,OMNIGRAPH_SERVER_BEARER_TOKEN=<token>. Railway terminates TLS at its edge and routes to the exposed 8080. - Day-2:
railway shell(orrailway 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 applyfrom 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.
Testing against S3 locally
To exercise the S3 storage path without a cloud account, run any S3-compatible
store in Docker and point the standard AWS_* environment at it. RustFS is
shown; MinIO works the same way.
docker run -d --name omnigraph-s3 -p 9000:9000 \
-e RUSTFS_ACCESS_KEY=omnigraph -e RUSTFS_SECRET_KEY=omnigraph \
-e RUSTFS_ALLOW_INSECURE_DEFAULT_CREDENTIALS=true \
rustfs/rustfs:latest /data
export AWS_ACCESS_KEY_ID=omnigraph AWS_SECRET_ACCESS_KEY=omnigraph \
AWS_REGION=us-east-1 AWS_ENDPOINT_URL_S3=http://127.0.0.1:9000 \
AWS_ALLOW_HTTP=true AWS_S3_FORCE_PATH_STYLE=true
# create the bucket once (any S3 client works)
aws --endpoint-url "$AWS_ENDPOINT_URL_S3" s3 mb s3://omnigraph-local
Now an s3://… URI works anywhere a graph or cluster root is expected. Root a
cluster on the bucket and serve it config-free:
# cluster.yaml
# version: 1
# storage: s3://omnigraph-local/clusters/demo
# graphs: { demo: { schema: schema.pg } }
omnigraph cluster validate --config .
omnigraph cluster import --config .
omnigraph cluster apply --config . --as you
omnigraph load --data seed.jsonl --mode merge \
s3://omnigraph-local/clusters/demo/graphs/demo.omni
omnigraph-server --cluster s3://omnigraph-local/clusters/demo \
--bind 127.0.0.1:8080 --unauthenticated
The same AWS_* contract applies to a production object store — swap the
endpoint and credentials. CI exercises this path against containerized RustFS.
Container Deployment
Build the image:
docker build -t omnigraph-server:local .
The server boots from a cluster only (RFC-011). Run against a cluster directory on a mounted volume:
docker run --rm -p 8080:8080 \
-v "$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). |
OMNIGRAPH_REQUIRE_ALL_GRAPHS |
When truthy, forwarded as --require-all-graphs: any graph-local quarantine or startup failure aborts cluster boot instead of serving the healthy subset. |
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:
- AWS Secrets Manager (build with
--features aws, see below) — setOMNIGRAPH_SERVER_BEARER_TOKENS_AWS_SECRETto the secret ID or ARN. - 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.
- Single-token env —
OMNIGRAPH_SERVER_BEARER_TOKEN(assigns the implicit actordefault).
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_IDAWS_SECRET_ACCESS_KEYAWS_REGION- optional
AWS_ENDPOINT_URL - optional
AWS_ENDPOINT_URL_S3 - optional
AWS_ALLOW_HTTP=true - optional
AWS_S3_FORCE_PATH_STYLE=true
