Pulumi Files

3.211.0 (2025-12-11)

Features

• [cli/about] Print Node.js package manager information in pulumi about #21163

• [backend/diy] Add stack tags support for DIY backends (S3, Postgres, file-based, etc.).

DIY backends now support stack tags functionality, bringing feature parity with cloud backends. This includes:

• Full CRUD operations for stack tags (create, read, update, delete)
• Automatic system tag injection (e.g., pulumi:project)
• Tag filtering support in stack listing operations
• Backward compatibility with existing stacks (no tags file required)
• Atomic operations with caching for performance
• Automatic cleanup of tag files when stacks are deleted

Tags are stored as separate .pulumi-tags files alongside stack checkpoints, using a versioned JSON format. The implementation works across all DIY backend storage types including S3, Azure Blob, Google Cloud Storage, PostgreSQL, and local file systems.

Example usage:

:::bash
pulumi stack tag set environment production
pulumi stack tag set owner backend-team
pulumi stack ls --tag-filter environment=production
