jcoffey-dev 1d57e697b1 Phase 4: real per-tenant ClickHouse isolation via a new enterprise-api binary
Closes the threat model's headline finding for the SQL query path:
enterprise/internal/tenantprovision does real CREATE DATABASE/USER/GRANT
against ClickHouse, and enterprise/internal/chrunner is a per-tenant
connection registry implementing api's SQLRunner interface, resolving
the tenant from the authenticated request identity -- never a
caller-suppliable parameter. Both are wired into a new binary,
enterprise/cmd/enterprise-api, alongside the unchanged single-tenant
api/cmd/api, since AGPL core can never import enterprise/ and Go's own
internal/ package visibility rules meant enterprise/ couldn't implement
core's SQLRunner interface without importing the package that defines
it. That required moving api/internal/{authz,queryapi,dashboards,
querylang/executor,searchclient,httpserver} out of internal/ -- the
minimal set enterprise-api needs to import; querylang's compiler
internals (planner/lexer/parser/ast/ir) and api's own config stay
internal, since nothing outside api needs them directly.

Also finally wires enterprise/internal/audit into queryapi.AuditLogger
(nil since Phase 4 task 4) via a new adapter, and adds live-ClickHouse
integration tests for two of the four adversarial probes named in
docs/phase-4-isolation-design.md's verification plan.

Corrected several overclaims in the docs while writing this up: an
earlier claim that rbacstore's CRUD was "verified against a live
Postgres" was never actually true in this environment (only
internal/audit was, earlier in this phase, before Docker access was
lost) -- threat-model.md, phase-4-runbook.md, CLAUDE.md, and
enterprise/README.md all now distinguish "a real integration test
exists" from "this was confirmed against a live database."

Still not built: Tantivy/free-text tenant isolation
(enterprise/internal/searchclient), and any deployment-topology
mechanism that actually routes traffic to enterprise-api instead of
plain api -- both binaries exist side by side today with nothing
enforcing or flagging which one a deployment runs.

# Phase 4 runbook
Extends `/docs/phase-0-runbook.md` through `/docs/phase-3-runbook.md`
with SSO plumbing, RBAC enforcement, tenant-scoped dashboards, audit
logging, and a Kubernetes deployment path. Read those first.
## Verification status — read this before the rest of this doc
Every prior phase's runbook documents claims **checked against the live
stack**, not asserted. This one is different, and says so plainly rather
than papering over it: for the great majority of this phase's work,
**there was no working Docker daemon access and no reachable Kubernetes
cluster**, so most of what follows is a *procedure to run*, not a report
of what was already run and passed. One genuine exception, verified live
against a real Postgres earlier in this phase's work (see its own doc
comments for the exact `docker run` invocations, and note this was
before the environment lost Docker access, not a claim about this
runbook's own session):
- `enterprise/internal/audit`'s hash-chain, tamper-detection, and
concurrent-write guarantees (task 4).
Everything else — `internal/rbacstore`'s CRUD, the auth-enforcement
walkthrough, the dashboards tenant-scoping fix, the Helm chart, the
tenant-operator, and (newest) `internal/tenantprovision`/
`internal/chrunner`'s live-ClickHouse tests — has unit/fake-client/
`helm template` coverage (all passing, see each component's own `go
test`/`helm lint` output, including every `Skip*`-gated integration test
confirmed to skip cleanly offline) but has **not** been exercised
against a real running stack. Be specific when citing this runbook: "the
tests exist and pass structurally" is a true, verified claim; "isolation
was confirmed against real ClickHouse" is not, yet. If you're reading
this to decide whether Phase 4 is production-ready: it isn't yet,
independent of this gap — see `/docs/security/threat-model.md`'s
headline finding. This runbook exists so the first person with real
Docker/K8s access can actually close the loop, not to claim that already
happened.
## 1. Bring up the stack
```sh
docker compose build enterprise-auth api alerting web
docker compose up -d
docker compose ps
```
New service beyond Phase 3: `enterprise-auth` (port 8082) — see
`enterprise/README.md`. Not wired into `api`/`alerting`'s enforcement by
default (`docker-compose.yml`'s comment on why: no OIDC/SAML login flow
exists yet, so turning on enforcement by default would break the web UI
and `sentryctl` with no way to log in).
## 2. Confirm Phase 0-3 behavior is unchanged
Every existing single-tenant flow must still work exactly as before —
this is the regression check for the nil-authorizer no-op design running
through every piece of Phase 4 auth wiring:
```sh
curl -s -X POST http://localhost:8080/query -H 'Content-Type: application/json' -d '{"query":"stats count"}'
sentryctl dashboards list
curl -s http://localhost:8081/healthz
```
All three should behave exactly as in the Phase 3 runbook — no auth
required, since `ENTERPRISE_AUTH_URL`/`API_SERVICE_TOKEN` aren't set.
## 3. `enterprise-auth`: mint and validate a service token
```sh
curl -s http://localhost:8082/healthz && echo " <- OK"
TOKEN=$(docker compose run --rm enterprise-auth -mint-service-token=alerting)
echo "$TOKEN"
curl -s -X POST http://localhost:8082/internal/authorize -H "Authorization: Bearer $TOKEN"
# expect: {"tenant_id":"","user_id":"","role":"service"}
curl -s -o /dev/null -w "invalid token -> %{http_code}\n" \
-X POST http://localhost:8082/internal/authorize -H "Authorization: Bearer garbage"
# expect: 401
curl -s http://localhost:8082/auth/features
# expect: {"sso_configured":false,"oidc_enabled":false,"saml_enabled":false}
# (no OIDC_ISSUER_URL/SAML_IDP_METADATA_URL set in this compose file)
```
## 4. Turn on RBAC enforcement and prove it actually blocks/allows
Without touching the main stack's `api` container (so step 2's baseline
keeps working):
```sh
docker compose run --rm -d --name sentry-api-enforced -p 8090:8080 \
-e ENTERPRISE_AUTH_URL=http://enterprise-auth:8082 api
curl -s -o /dev/null -w "no auth -> %{http_code} (want 401)\n" \
-X POST http://localhost:8090/query -H 'Content-Type: application/json' -d '{"query":"stats count"}'
curl -s -o /dev/null -w "with service token -> %{http_code} (want 200)\n" \
-X POST http://localhost:8090/query -H "Authorization: Bearer $TOKEN" \
-H 'Content-Type: application/json' -d '{"query":"stats count"}'
docker stop sentry-api-enforced
```
`GET /dashboards` on the same enforced instance should return 401
without a token — there's no way to mint a human (Viewer/Editor/etc.)
session yet (no OIDC/SAML login handler exists — see
`enterprise/cmd/enterprise-auth/main.go`'s doc comment), so this
runbook can't walk through a real human RBAC scenario end to end. That
gap is real, not an oversight in this runbook.
## 5. Dashboards tenant scoping
This is the fix from Phase 4 task 7/8 (see `/docs/security/threat-model.md`)
— every dashboards query is now scoped to the authenticated identity's
tenant. Verify the real SQL, not just the fake-store unit tests:
```sh
docker run --rm --network sentry_default -v $(pwd)/api:/src -w /src \
-e DASHBOARDS_TEST_POSTGRES_ADDR=metadata-postgres:5432 \
-e DASHBOARDS_TEST_POSTGRES_PASSWORD=sentry-dev-only \
golang:1.25-alpine go test ./internal/dashboards/... -run Integration -v
```
Expect all `TestIntegration*` tests to pass, including
`TestIntegrationDashboardTenantForeignKeyRejectsUnknownTenant` (the
`tenant_id` foreign key added in
`metadata/migrations/0027_add_dashboards_tenant_fk.sql` rejecting a
dashboard for a tenant that doesn't exist).
## 6. `enterprise/internal/rbacstore` and `internal/audit` (already verified — reconfirm here)
```sh
docker run --rm --network sentry_default -v $(pwd)/enterprise:/src -w /src \
-e RBACSTORE_TEST_POSTGRES_ADDR=metadata-postgres:5432 \
-e RBACSTORE_TEST_POSTGRES_PASSWORD=sentry-dev-only \
golang:1.25-alpine go test ./internal/rbacstore/... -v
docker run --rm --network sentry_default -v $(pwd)/enterprise:/src -w /src \
-e AUDIT_TEST_POSTGRES_ADDR=metadata-postgres:5432 \
-e AUDIT_TEST_POSTGRES_PASSWORD=audit-writer-dev-only \
-e AUDIT_TEST_ADMIN_PASSWORD=sentry-dev-only \
golang:1.25-alpine go test ./internal/audit/... -v
```
## 7. `deploy`: Helm chart and Operator (offline-only so far — see `/deploy/README.md`)
No live cluster was available to `kubectl apply` any of this. What can
be checked without one:
```sh
cd deploy/operator && go build ./... && go vet ./... && go test ./...
cd ../helm/sentry
helm lint .
helm template sentry . --include-crds > /tmp/default.yaml
helm template sentry . --include-crds \
--set enterprise.enabled=true --set tenantOperator.enabled=true \
--set 'tenants[0].name=acme' --set 'tenants[0].displayName=Acme Corp' \
--set 'tenants[1].name=globex' --set 'tenants[1].displayName=Globex Corporation' \
> /tmp/multitenant.yaml
```
With a real cluster reachable (`kind create cluster`, or similar):
```sh
docker build -f deploy/operator/Dockerfile -t sentry-tenant-operator deploy/operator/
kind load docker-image sentry-tenant-operator # or push to a registry the cluster can pull from
helm install sentry deploy/helm/sentry --include-crds \
--set tenantOperator.enabled=true --set enterprise.enabled=true \
--set 'tenants[0].name=acme' --set 'tenants[0].displayName=Acme Corp'
kubectl get tenants
kubectl get secret sentry-tenant-acme-clickhouse -o yaml
```
Expect `kubectl get tenants` to show `acme` reach `status.phase: Active`
and the Secret to contain a generated `username`/`password`/`database`.
This proves the K8s-side half of a real two-tenant deployment — it does
**not** provision a working ClickHouse database itself (the Operator
manages the K8s Secret only); §8 below is the piece that actually
provisions ClickHouse.
## 8. `enterprise-api`: real per-tenant ClickHouse isolation
This is new since this runbook was first written — `enterprise/internal/
tenantprovision` and `enterprise/internal/chrunner` now exist, closing
the headline gap §"Known gaps" below used to describe as completely
unbuilt. It's still a second binary you have to choose to run, though —
see `/docs/security/threat-model.md`'s "Read this first" section.
```sh
docker compose build enterprise-api
docker compose run --rm enterprise-api -provision-tenant=acme -display-name="Acme Corp"
docker compose run --rm enterprise-api -provision-tenant=globex -display-name="Globex Corporation"
docker compose up -d enterprise-api
curl -s http://localhost:8083/healthz
```
There's still no OIDC/SAML login handler and no CLI for minting a human
session token (see `/docs/security/threat-model.md`) -- so a real
`curl -X POST http://localhost:8083/query` walkthrough as tenant acme
isn't possible yet. Confirm isolation end to end against the live stack (this is the same
assertion `enterprise/internal/chrunner/chrunner_test.go`'s
`TestRegistryTenantCannotReadOtherTenantEvenViaRawSQL` makes, run here
as an integration test instead of a curl walkthrough since there's no
login flow to drive it through curl yet):
```sh
docker run --rm --network sentry_default -v $(pwd)/enterprise:/src -w /src \
-e CHRUNNER_TEST_CLICKHOUSE_ADDR=clickhouse:9000 \
-e CHRUNNER_TEST_CLICKHOUSE_PASSWORD=sentry-dev-only \
golang:1.25-alpine go test ./internal/chrunner/... -v
docker run --rm --network sentry_default -v $(pwd)/enterprise:/src -w /src \
-e TENANTPROVISION_TEST_CLICKHOUSE_ADDR=clickhouse:9000 \
-e TENANTPROVISION_TEST_CLICKHOUSE_PASSWORD=sentry-dev-only \
golang:1.25-alpine go test ./internal/tenantprovision/... -v
```
Expect all tests to pass, including
`TestProvisionedUserCannotReadSystemTables` (item 2 of
`/docs/phase-4-isolation-design.md`'s verification plan, closed this
pass) and `TestRegistryTenantCannotReadOtherTenantEvenViaRawSQL` (item 1,
closed through the actual production code path, not just
tenantprovision's raw grants).
## Known gaps (do not treat this phase as done without reading these)
Full accounting: `/docs/security/threat-model.md`. Headline items:
- **ClickHouse isolation exists but is opt-in.** `enterprise-api`
(§8) gives real per-tenant ClickHouse isolation, but plain `api`
(still the default in `docker-compose.yml`/`web`'s base URL) has none,
and nothing flags which one a given deployment is actually running.
- **No Tantivy/free-text isolation at all**, regardless of which binary
serves the request -- `enterprise/internal/searchclient` (chrunner's
Tantivy-side sibling) doesn't exist.
- **No human SSO login.** OIDC/SAML protocol wiring exists;
the HTTP login/callback handlers that would use it don't.
- **No per-resource dashboard grants** (`dashboard_permissions` has a
schema, no handler reads it).
- Two of the four adversarial ClickHouse/Tantivy probes named in
`/docs/phase-4-isolation-design.md`'s verification plan are closed
(§8); the other two (Tantivy cross-tenant search, mid-provisioning-race
handling) are still stubbed as explicitly-skipped tests in
`api/queryapi/tenant_isolation_gap_test.go`.
## Tearing down
```sh
docker compose down -v
helm uninstall sentry # if installed against a real cluster
```
## Troubleshooting
**`enterprise-auth` fails to start with "ENTERPRISE_SESSION_SIGNING_KEY
must be set to at least 32 bytes".**
Required, unlike OIDC/SAML config — see `enterprise/internal/config.Load`.
`docker-compose.yml`'s dev value is long enough; a custom override must
be too.
**`POST /query` returns 401 even though `ENTERPRISE_AUTH_URL` isn't
set.**
Check `api/cmd/api/main.go` actually left `authorizer` nil when
`cfg.EnterpriseAuthURL == ""` — a nil `Authorizer` must be a no-op
(`api/authz.RequireRole`'s doc comment). If this regresses, it
breaks every existing Phase 0-3 deployment silently.
**A dashboard created by one tenant is visible to another.**
This is the exact bug found and fixed in task 7 — see
`/docs/security/threat-model.md`'s "application-layer tenant scoping"
section and `api/dashboards/handler_test.go`'s
`TestCrossTenant*` tests. If this regresses, `Handler.tenantID` or
`store.go`'s `WHERE tenant_id = ...` filters have been bypassed
somewhere — check every store method still takes and uses a `tenantID`
parameter.
**`helm template` fails with `error calling include: ... can't evaluate
field Release in type string`.**
A call site is passing a bare string to `sentry.selectorLabels` instead
of `(list $ "name")` — see `templates/_helpers.tpl`'s doc comment for
why the plain-string form doesn't work with `include`.
