# OCI Object Storage — Buckets, PARs & Lifecycle ## Overview Manage OCI Object Storage using the Python SDK. Object Storage is OCI's S3 equivalent, but PAR (Pre-Authenticated Request) URLs expire silently with no error — the URL just returns 404. Multipart uploads over 50GB require manual part management. Lifecycle policies can delete data unexpectedly if misconfigured. This skill covers the safe patterns for all of these operations. **Purpose:** Upload, download, and share objects safely with proper PAR expiry management and lifecycle policy configuration. ## Prerequisites - **OCI Python SDK** — `pip install oci` - **Config file** at `~/.oci/config` with fields: `user`, `fingerprint`, `tenancy`, `region`, `key_file` - **IAM policy** — `Allow group Developers to manage objects in compartment <name>` - **Python 3.8+** ## Instructions ### Step 1: Discover Namespace and Create a Bucket Every OCI tenancy has a unique Object Storage namespace. You must discover it before any operation. ```python import oci from datetime import datetime, timedelta config = oci.config.from_file("~/.oci/config") storage = oci.object_storage.ObjectStorageClient(config) # Namespace is tenancy-specific — discover it, never hardcode namespace = storage.get_namespace().data print(f"Namespace: {namespace}") # Create bucket bucket = storage.create_bucket( namespace_name=namespace, create_bucket_details=oci.object_storage.models.CreateBucketDetails( compartment_id=config["tenancy"...
