Prepares the runner for Supabase's publishable/secret keys, which replace the legacy anon/service_role keys.

What changed

  • supabase client bump + 2.28 integration fixes: the pinned 2.5.1 rejects sb_publishable_ keys in create_client before any request is made. The bump also required following the client's API moves — SyncClientOptions, and frq.request.params in custom_filter_request_builder.
  • fetch_supabase_api_key() + KEY_CACHE in supabase_dal.py: on connect the runner asks relay (GET /api/config/supabase-keys) for the current key, reporting account_id, cluster, component=runner and component_version. The key is cached (cachetools TTLCache, 24h) only after it signs in successfully; a cached key that fails is dropped and the relay key retried, then the api_key from the Robusta token is used as the fallback with failures propagating as before.
  • __connect is the single login path: the expired-JWT retry in patch_postgrest_execute now re-runs __connect instead of sign_in, so a long-lived runner re-reads the cache and re-fetches from relay on session expiry rather than reusing the key chosen at startup.

Footprint of the key-fetch part is ~35 lines in one file, using the requests and TTLCache imports the DAL already had.

Backward compatibility

Relays without the endpoint simply fail the fetch, and the runner uses the token's key exactly as today. Relay side: robusta-dev/relay#747.

Testing

Verified live on a staging-connected cluster:

  • Runner starts clean on the new image (sink initialized, relay websocket connected, cluster status flowing, no errors).
  • With a bogus api_key in robusta_sink.token the runner still signs in — proving the relay-provided key is what's in use.
  • With ROBUSTA_API_ENDPOINT pointed at an unreachable host, it logs one warning and falls back to the local key.
  • Relay's supabase_key_requests_total counter shows the runner's fetches labeled by account, cluster, component and version.

Bump supabase 2.5.1 -> 2.28.1, which accepts the new sb_publishable_
key format alongside legacy anon JWTs. supabase >=2.22.4 requires
pydantic v2, so bump pydantic to ^2.11.7 and switch robusta code to
the pydantic.v1 compatibility shim (same approach prometrix uses),
keeping v1 behavior unchanged. Drop the postgrest pin (now resolved
via supabase) and add websockets>=13 required by realtime.

Two breaks from the supabase 2.5.1 -> 2.28.1 bump, found while testing the
runner against staging:

- ClientOptions from supabase.lib.client_options is the async variant on new
  versions and has no storage default, so create_client raised
  AttributeError: 'ClientOptions' object has no attribute 'storage'. Use
  SyncClientOptions, matching relay.
- postgrest moved query params onto the request object, so the or= filter in
  custom_filter_request_builder was set on the wrong target (account-resources
  fetch / CR rules). Mirror how the new .filter() mutates itself.

On sink init the runner asks relay (/api/config/supabase-keys) for the
current publishable key, reporting account, cluster, component and
version. A key is cached for 24h only after it signed in successfully;
a cached key that stops working is invalidated and re-fetched. If the
fetch or the fetched key fails, the runner falls back to the api_key
embedded in the Robusta token, preserving today's behavior.

Drops the bespoke cache class for a module-level cachetools TTLCache and
a small fetch function. The expired-JWT retry now re-runs __connect, so
a long-lived runner re-reads the cache and re-fetches from relay instead
of only re-signing in with the key chosen at startup.

Walkthrough

The project upgrades Pydantic and Supabase dependencies, routes existing Pydantic v1 APIs through pydantic.v1, adds label-based workflow rate limiting, improves Supabase authentication, and handles missing Kubernetes pod conditions.

Changes

Compatibility and runtime updates

Layer / File(s) Summary
Dependency and authentication foundations
pyproject.toml, src/robusta/core/sinks/robusta/dal/supabase_dal.py, tests/test_supabase_dal_sign_in.py, tests/test_supabase_key_fetch.py
Dependencies support Pydantic v1 compatibility, Supabase realtime, and retry handling. Supabase authentication adds relay-key selection, caching, HTTP timeouts, retries, and JWT reconnection.
Workflow trigger rate limiting
playbooks/robusta_playbooks/workflow_trigger.py, tests/test_workflow_trigger.py
Workflow triggers can rate-limit alerts by selected labels and workflow IDs. Tests cover suppression, label differences, expiration, and default behavior.
Pydantic v1 compatibility imports
docs/_ext/autorobusta.py, playbooks/robusta_playbooks/*, scripts/*, src/robusta/core/*, src/robusta/integrations/*, src/robusta/model/*, src/robusta/runner/*, src/robusta/utils/*, tests/*
Pydantic model, field, validator, secret, settings, and dataclass imports now use the pydantic.v1 compatibility namespace.
Discovery edge-case handling
src/robusta/core/discovery/discovery.py
Pod readiness checks treat missing or unset pod conditions as empty conditions.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 3e7ca

The PR changes runner authentication recovery and workflow-trigger behavior, but the current head still has unresolved risks that could cause authentication recovery failures, documentation or lint failures, incorrect alert rate limiting, or missed workflow triggers. These issues should be fixed or explicitly accepted before merging.

namespace, including ModelField and all SHAPE_* constants. Avoid accessing these
helpers through pydantic.fields so the extension remains compatible with
Pydantic 2.

Keeps both sides of supabase_dal: master's auth-client timeout and login
retries, and this branch's supabase 2.28 bump plus the relay key fetch.
__login now applies the auth timeout, and the gotrue imports move to
supabase_auth, which is where 2.28 ships them.

Release a rate-limit reservation when delivery fails.

Line 108 records the bucket before the webhook request runs. If the request later raises or returns a non-2xx response, matching alerts are skipped for the configured period although no successful trigger was confirmed. Add reservation lifecycle handling that cancels the bucket on failed delivery and commits it only after a successful response.

Use an unambiguous rate-limit key encoding.
