Caster is the primary deployment component of the Crucible framework. Caster provides a web interface that gives exercise developers a way to create, share, and manage topology configurations.

Caster.Api utilizes the Terraform binary in order execute workspace operations. Because this binary is running inside of the Caster.Api service, restarting or stopping the Caster.Api Docker container while a Terraform operation is in progress can lead to a corrupted state.

In order to avoid this, a System Administrator should follow these steps in the Caster UI before stopping the Caster.Api container:

• Navigate to Administration > Workspaces
• Disable Workspace Operations by clicking the toggle button
• Wait until all Active Runs are completed
