From a815cbcf3e189fee40934352d1968cc65893ddbb Mon Sep 17 00:00:00 2001 From: PeninsulaInd Date: Wed, 10 Dec 2025 14:57:44 -0600 Subject: [PATCH] Story 6.2: Implement AWS S3 Storage Client - Add S3StorageClient class implementing StorageClient Protocol - Support AWS S3 and S3-compatible services with custom endpoints - Automatic bucket configuration for public read access only - Content-type detection for uploaded files - URL generation (default S3 URLs and custom domain support) - Error handling for common S3 errors (403, 404, NoSuchBucket, etc.) - Retry logic with exponential backoff (consistent with BunnyStorageClient) - Update storage_factory to return S3StorageClient for 's3' and 's3_compatible' - Add comprehensive unit tests with mocked boto3 calls (18 tests, all passing) Implements Story 6.2 from Epic 6: Multi-Cloud Storage Support --- src/deployment/s3_storage.py | 414 +++++++++++++++++++++++++++++ src/deployment/storage_factory.py | 63 +++++ tests/unit/test_s3_storage.py | 395 +++++++++++++++++++++++++++ tests/unit/test_storage_factory.py | 63 +++++ 4 files changed, 935 insertions(+) create mode 100644 src/deployment/s3_storage.py create mode 100644 src/deployment/storage_factory.py create mode 100644 tests/unit/test_s3_storage.py create mode 100644 tests/unit/test_storage_factory.py diff --git a/src/deployment/s3_storage.py b/src/deployment/s3_storage.py new file mode 100644 index 0000000..184292f --- /dev/null +++ b/src/deployment/s3_storage.py @@ -0,0 +1,414 @@ +""" +AWS S3 Storage API client for uploading files to S3 buckets +Story 6.2: AWS S3 Client Implementation +""" + +import os +import time +import logging +import json +from typing import Optional, TYPE_CHECKING +from dataclasses import dataclass + +import boto3 +from botocore.exceptions import ClientError, BotoCoreError +from botocore.config import Config + +if TYPE_CHECKING: + from src.database.models import SiteDeployment + +from src.deployment.bunny_storage import UploadResult + +logger = logging.getLogger(__name__) + + +class S3StorageError(Exception): + """Base exception for S3 Storage API errors""" + pass + + +class S3StorageAuthError(S3StorageError): + """Authentication error with S3 Storage API""" + pass + + +class S3StorageClient: + """Client for uploading files to AWS S3 buckets""" + + def __init__(self, max_retries: int = 3): + """ + Initialize S3 Storage client + + Args: + max_retries: Maximum number of retry attempts for failed uploads + """ + self.max_retries = max_retries + self._client_cache = {} + + def _get_s3_client(self, region: Optional[str] = None, endpoint_url: Optional[str] = None): + """ + Get or create boto3 S3 client with credentials from environment + + Args: + region: AWS region (optional, uses AWS_REGION env var or default) + endpoint_url: Custom endpoint URL for S3-compatible services + + Returns: + boto3 S3 client instance + + Raises: + S3StorageAuthError: If AWS credentials are missing + """ + # Create new client if endpoint_url changes (for s3_compatible) + cache_key = f"{region or 'default'}:{endpoint_url or 'default'}" + if not hasattr(self, '_client_cache'): + self._client_cache = {} + + if cache_key not in self._client_cache: + access_key = os.getenv('AWS_ACCESS_KEY_ID') + secret_key = os.getenv('AWS_SECRET_ACCESS_KEY') + default_region = os.getenv('AWS_REGION', 'us-east-1') + + if not access_key or not secret_key: + raise S3StorageAuthError( + "AWS credentials not found.
