Manage IACM Workspace Plugin Reference

The Manage IACM Workspace plugin provides full lifecycle management for Harness IACM workspaces. Use it in your Harness pipelines to create, update, query, or delete IACM workspaces, manage variables and secrets, and perform bulk tag refactoring — all through a single, configurable plugin step.

Important notes

info

• The plugin requires Python 3.11+ and Docker with buildx support at runtime.
• The remove operation is destructive and irreversible. Use it only after confirming the correct workspace identifier.
• Secret variables (PLUGIN_RESOURCE_VARS_SECRETS, PLUGIN_RESOURCE_VARS_ENVS_SECRETS) are passed as Harness secret references and are never logged or exposed in plain text.

Operation modes

Set the PLUGIN_SWITCH variable to control what the plugin does.

Mode	Alias	Description
main	register	Create or update an IACM workspace with variables and configuration
view	—	Query and retrieve workspace details; supports filtering by tags and attributes
remove	—	⚠️ Delete a workspace by identifier (destructive)
refactor	—	Bulk-update workspace tags and source classification

Use in Harness pipelines

Add the plugin as a Plugin step in your stage. The examples below cover each operation mode.
