Edit VM template variables

Excerpt
nameEdit VM template variables

To add variables to a VM template, enter the Key and Value, then click Add.

To edit an existing value, click the pencil icon, enter the new Value, then click ok. To save your changes to the template, click Save.

The variables will be added automatically to new VMs. Users can edit the variables when configuring the VM.

After the VM deploys, users can then access variables in the guest.
For example, AWS stores the variables in the ~/vm-variables.rc file. Cloud-init may use variables. Remember to check your provider documentation about metadata security.

Excerpt
nameShare VM templates

In the Catalogue view, shared templates are marked with the outstretched hand symbol. 

Panel

Privileges: Allow user to switch enterprises

By default, templates are local to the tenant that creates them (the "owner" enterprise). To share templates, assign scopes to them. 

Tip

Users who belong to the owner enterprise or enterprises in a template's scopes can display and use the template. 

To share a template with a scope:

  1. Go to Users → Scopes

  2. Create a scope

    1. For enterprises to use the template, select them in the scope

  3. Log in or switch to the enterprise that owns the template

  4. Go to Catalogue → Templates

  5. Edit a template

  6. Go to Scopes

  7. Select the scope

For more information, see Manage scopes and Manage resource scopes

To share a template with the enterprises in one or more scopes, select template scopes.

Image RemovedImage Added

To remove enterprise access to a template, remove the scope containing the enterprise. 

  • You cannot remove a scope from the template if an enterprise in the scope is using the template, for example, if it has deployed VMs or instances of VMs. 

To make a template private to the owner enterprise, unselect all scopes.

In private cloud, the instances of shared templates belong to the enterprise that created them. When a template has instances, it is "in use" by the enterprises with instances. This may mean that you cannot delete a template without deleting or promoting the instances first.

When you make a shared template unavailable, other enterprises cannot deploy it, but it may not be marked as "unavailable" in the Catalogue of other enterprises until you refresh your Catalogue.
