From 299c86f002291ba219d74c30d2ea6203ecf5405f Mon Sep 17 00:00:00 2001 From: chrislu Date: Sun, 24 Aug 2025 11:51:57 -0700 Subject: [PATCH] feat: Add Keycloak OIDC integration for S3 IAM tests - Add Docker Compose setup with Keycloak OIDC provider - Configure test realm with users, roles, and S3 client - Implement automatic detection between Keycloak and mock OIDC modes - Add comprehensive Keycloak integration tests for authentication and authorization - Support real JWT token validation with production-like OIDC flow - Add Docker-specific IAM configuration for containerized testing - Include detailed documentation for Keycloak integration setup Integration includes: - Real OIDC authentication flow with username/password - JWT Bearer token authentication for S3 operations - Role mapping from Keycloak roles to SeaweedFS IAM policies - Comprehensive test coverage for production scenarios - Automatic fallback to mock mode when Keycloak unavailable --- test/s3/iam/Dockerfile.s3 | 33 +++ test/s3/iam/KEYCLOAK.md | 252 ++++++++++++++++++ test/s3/iam/Makefile | 67 ++--- test/s3/iam/docker-compose.yml | 121 +++++++++ test/s3/iam/iam_config_docker.json | 160 ++++++++++++ test/s3/iam/keycloak-realm.json | 138 ++++++++++ test/s3/iam/s3_iam_framework.go | 166 +++++++++++- test/s3/iam/s3_keycloak_integration_test.go | 272 ++++++++++++++++++++ 8 files changed, 1165 insertions(+), 44 deletions(-) create mode 100644 test/s3/iam/Dockerfile.s3 create mode 100644 test/s3/iam/KEYCLOAK.md create mode 100644 test/s3/iam/docker-compose.yml create mode 100644 test/s3/iam/iam_config_docker.json create mode 100644 test/s3/iam/keycloak-realm.json create mode 100644 test/s3/iam/s3_keycloak_integration_test.go diff --git a/test/s3/iam/Dockerfile.s3 b/test/s3/iam/Dockerfile.s3 new file mode 100644 index 000000000..36f0ead1f --- /dev/null +++ b/test/s3/iam/Dockerfile.s3 @@ -0,0 +1,33 @@ +# Multi-stage build for SeaweedFS S3 with IAM +FROM golang:1.23-alpine AS builder + +# Install build dependencies +RUN apk add --no-cache git make curl wget + +# Set working directory +WORKDIR /app + +# Copy source code +COPY . . + +# Build SeaweedFS with IAM integration +RUN cd weed && go build -o /usr/local/bin/weed + +# Final runtime image +FROM alpine:latest + +# Install runtime dependencies +RUN apk add --no-cache ca-certificates wget curl + +# Copy weed binary +COPY --from=builder /usr/local/bin/weed /usr/local/bin/weed + +# Create directories +RUN mkdir -p /etc/seaweedfs /data + +# Health check +HEALTHCHECK --interval=30s --timeout=10s --start-period=5s --retries=3 \ + CMD wget --quiet --tries=1 --spider http://localhost:8333/ || exit 1 + +# Set entrypoint +ENTRYPOINT ["/usr/local/bin/weed"] diff --git a/test/s3/iam/KEYCLOAK.md b/test/s3/iam/KEYCLOAK.md new file mode 100644 index 000000000..189373d39 --- /dev/null +++ b/test/s3/iam/KEYCLOAK.md @@ -0,0 +1,252 @@ +# Keycloak Integration for SeaweedFS S3 IAM Tests + +This document describes the integration of [Keycloak](https://github.com/keycloak/keycloak) as a real OIDC provider for SeaweedFS S3 IAM integration tests. + +## Overview + +The integration tests support both **mock OIDC** and **real Keycloak authentication**: + +- **Mock OIDC** (default): Fast, no dependencies, generates test JWT tokens locally +- **Keycloak OIDC** (optional): Real-world authentication using Keycloak as OIDC provider + +The test framework automatically detects if Keycloak is available and switches modes accordingly. + +## Architecture + +``` +┌─────────────┐ JWT Token ┌──────────────────┐ S3 API ┌─────────────────┐ +│ Keycloak │ ────────────► │ SeaweedFS S3 │ ────────► │ SeaweedFS │ +│ OIDC │ (Bearer) │ Gateway + IAM │ │ Storage │ +│ Provider │ │ │ │ │ +└─────────────┘ └──────────────────┘ └─────────────────┘ +``` + +1. **Test** authenticates user with Keycloak using username/password +2. **Keycloak** returns JWT access token with user roles and claims +3. **Test** creates S3 client with JWT Bearer token authentication +4. **SeaweedFS S3 Gateway** validates JWT token and enforces IAM policies +5. **S3 operations** are authorized based on user roles and attached policies + +## Quick Start + +### Option 1: Docker Compose (Recommended) + +Start everything with Docker Compose including Keycloak: + +```bash +cd test/s3/iam +make docker-test +``` + +This will: +- Start Keycloak with pre-configured realm and users +- Start SeaweedFS services (master, volume, filer, S3 gateway) +- Run Keycloak integration tests +- Clean up all services + +### Option 2: Manual Setup + +1.
