pcluster
✓ import pcluster
✗ from pcluster import pcluster

Quickstart for using ParallelCluster Python SDK to list clusters. Ensure AWS credentials are configured (e.g., via AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY).

import os from pcluster import pcluster client = pcluster.Client() # Note: Requires AWS credentials configured via environment variables or AWS CLI. # Example: list clusters clusters = client.list_clusters() print(clusters)
pcluster --version
Debug
Known issues
breakingIn version 3.x, the CLI and API structure changed significantly from 2.x. Old scripts using 'pcluster' commands may fail.
fix
Migrate to ParallelCluster 3.x by updating commands and configuration files. Refer to the official migration guide.
affects: <3.0
deprecatedUbuntu 20.04 support is deprecated and removed after 3.13.0.
fix
Use Ubuntu 22.04 or later for new clusters.
affects: >=3.13.0
gotchaThe Python SDK (pcluster) is separate from the CLI. Importing 'pcluster' directly may not provide all CLI functionality.
fix
Use the CLI commands (e.g., `pcluster create-cluster`) for cluster operations, or use the SDK for programmatic access.
affects: >=3.0
