| Manages Tempest workspaces |
| |
| This command is used for managing tempest workspaces |
| |
| Commands |
| ======== |
| |
| list |
| ---- |
| Outputs the name and path of all known tempest workspaces |
| |
| register |
| -------- |
| Registers a new tempest workspace via a given --name and --path |
| |
| rename |
| ------ |
| Renames a tempest workspace from --old-name to --new-name |
| |
| move |
| ---- |
| Changes the path of a given tempest workspace --name to --path |
| |
| remove |
| ------ |
| Deletes the entry for a given tempest workspace --name |
| |
| General Options |
| =============== |
| |
| **--workspace_path**: Allows the user to specify a different location for the |
| workspace.yaml file containing the workspace definitions |
| instead of ~/.tempest/workspace.yaml |
