Fixes CORE-1503 (part of CORE-1502).

The test (trino) and test (dremio) jobs fail on image pull:

pull access denied for minio/minio, repository does not exist or may require 'docker login'

MinIO removed its images from Docker Hub, and quay.io now rejects anonymous pulls. This ports dbt-data-reliability#1067 to tests/e2e_dbt_project:

  • trino-minio / trino-mc-job → trino-rustfs / trino-rustfs-setup (rustfs/rustfs:1.0.0, rustfs/rc:v0.1.36), plus the Trino Iceberg catalog.
  • dremio-minio / dremio-minio-setup → dremio-rustfs / dremio-rustfs-setup. The container name stays dremio-storage, so the Dremio source endpoints are unchanged.
  • The Dremio external seeder now uploads with a throwaway rustfs/rc container instead of minio/mc.
  • The setup containers wait on a storage healthcheck instead of retry loops.

Spark in this repo doesn't use MinIO, so it's unchanged.

Tested locally:

  • Trino: stack healthy; an Iceberg CTAS, insert and read through Trino round-trip to RustFS.
  • Dremio: stack healthy and dremio-setup passes. load_seeds_external.py dremio uploads to RustFS and loads the data with COPY INTO (179/179 rows checked on stats_players_training).

The full e2e flow for both runs in CI.

The test (sqlserver) job still fails until the dbt-sqlserver 1.12 PR (CORE-1504) merges. test (clickhouse) fails for an unrelated reason.

Summary by CodeRabbit

  • Tests
    • End-to-end dbt test environments now use RustFS instead of MinIO for Trino and Dremio object storage, with storage credentials configured for each service.
    • RustFS health checks and automatic datalake bucket setup are in place; Dremio startup waits for RustFS and bucket setup to finish.
    • Dremio test data seeding uploads training and validation files to RustFS while retaining the existing data paths and source configuration.

…stacks

MinIO images can no longer be pulled anonymously (removed from Docker Hub,
quay.io now requires auth), so the trino and dremio jobs fail on image pull.
Port of dbt-data-reliability#1067: use pinned rustfs/rustfs + rustfs/rc,
healthchecks instead of retry loops, and rc for the Dremio seed upload.

📝 Walkthrough

Walkthrough

The E2E warehouse configuration replaces MinIO with RustFS for Trino and Dremio. The changes update service setup, credentials, bucket creation, startup dependencies, and Dremio CSV seeding.

Changes

RustFS E2E storage

Layer / File(s) Summary
Trino RustFS services and catalog
.github/workflows/test-warehouse.yml, tests/e2e_dbt_project/docker-compose.yml, tests/e2e_dbt_project/docker/trino/catalog/iceberg.properties
Trino’s Hive Metastore and Iceberg catalog use RustFS endpoints and credentials. Compose defines the RustFS service and bucket setup, and updates service dependencies.
Dremio RustFS services and setup
.github/workflows/test-warehouse.yml, tests/e2e_dbt_project/docker-compose.yml, tests/e2e_dbt_project/docker/dremio/dremio-setup.sh
Compose defines Dremio’s RustFS service, persistent volume, health check, and bucket setup. Dremio setup and the warehouse workflow use RustFS credentials and services.
Dremio RustFS seeding
tests/e2e_dbt_project/external_seeders/dremio.py
The seeder reads RustFS credentials, creates the datalake bucket, and uploads training and validation CSVs with rustfs/rc. The S3 source configuration uses the RustFS credentials.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to 48749

The seeder now reads the Dremio RustFS credential overrides, addressing the previously identified seeding failure. No concrete merge-blocking issue remains established.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 48749

The change is confined to test warehouse infrastructure and reduces direct storage-port exposure to localhost. No introduced security vulnerability was established. Some uncertainty remains around the new storage client's recovery behavior and credential handling in customized environments.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The configured seeding authority reaches the test storage service and Dremio catalog/table mutations, while the upload container receives read-only access to the selected host seed directory. Loopback bindings reduce remote host-port exposure but do not isolate storage from local processes or peers on its Docker network. Permission enforcement inside the replacement images was not verified.

Security Findings and Attack Paths

  • observed — The changed upload shell uses fixed commands and quoted credential-variable expansions. Seed contents and the host directory path are not interpolated into that shell string. The host runner continues to use an argument list, and the seed mount remains read-only; these inspected paths do not establish a new shell-injection route.

Trust Boundaries and Controls

  • inferred — Credential consistency remains conditional in customized environments: generic RUSTFS values override Dremio-specific values, while Compose configures storage from the Dremio-specific names. The analogous generic-versus-service-specific divergence existed with MinIO. Neither revision explicitly forwards those overrides into its storage setup container. These are inherited configuration fragilities, not established new privilege escalation or boundary bypass.

Resilience and Maintainability Implications

  • inferred — Upload failure still stops execution before Dremio mutation. Later source and table operations remain non-atomic, and interruption or concurrent/repeated loads can leave partial state as before. The replacement client's object-copy overwrite and recovery semantics remain an unverified compatibility boundary rather than a demonstrated regression.

Hardening Proposals

  • proposed — A single Dremio-specific credential contract, explicit forwarding into bucket setup, and rejection of conflicting generic credentials would reduce inherited identity drift across storage, upload, and catalog consumers.

🟡 Minor · Honor the DREMIO RustFS credential overrides. · dremio.py:84-88

tests/e2e_dbt_project/external_seeders/dremio.py:84-88
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Honor the DREMIO RustFS credential overrides.

Compose applies DREMIO_RUSTFS_* values to RustFS and dremio-setup. The seeder reads only RUSTFS_* and parsed defaults. When an override differs from the default, the upload and SeedFiles source can use credentials RustFS rejects. Read the DREMIO_RUSTFS_* variables after the existing RUSTFS_* variables and before the parsed defaults.

- Dremio seeder honors the DREMIO_RUSTFS_* overrides that docker-compose
  applies to RustFS (after RUSTFS_*, before the compose defaults).
- Fix the Trino RustFS keys in compose: docker/trino/catalog/iceberg.properties
  hardcodes them, so the TRINO_RUSTFS_* overrides could only break Trino.
- Look up the Dremio network from the dremio-storage container instead of
  assuming the e2e_dbt_project compose project name (DREMIO_NETWORK still
  overrides).
