Tagging Resources (IAM on the Appliance)

Private Cloud Appliance tagging enables you to add metadata to resources by applying key/value pairs called defined tags or free-form tags. You can create tag defaults on compartments, which are tags that are automatically applied to all newly created resources in the tagged compartment.

Uses for tags include the following. For more information about using tags, see Using Resource Tags (IAM on the Appliance).

• Applying policies to resources. For example, if you apply access policies to resources, you can change ownership of a resource to a different product group by changing a tag value on the resource rather than changing the resource access policy directly.

• Filtering resource lists.

• Applying parameter values to some resources.

Private Cloud Appliance supports two types of tags:

• Free-form tags enable any user who has authorization to update a resource to quickly and conveniently include relevant information in the metadata of the resource.

  • Before applying a free-form tag, you cannot see a list of free-form tags that are already in use in your tenancy. You can use the resource get operation to view only the free-form tags that are applied to a specified resource.

  • Free-form tags provide unmanaged metadata. You cannot enforce use of particular keys or values for free-form tags.

  • Free-form tags cannot be used in policy statements.

• Defined tags enable you to enforce use of particular keys and values. Related tags can be grouped into a common tag namespace.

  • Tag namespaces with tag key definitions must exist in the tenancy before users can apply a defined tag to a resource. You can see them by listing tag namespaces.

  • You can allow users to enter a value, or you can require that users select from a list of values.

  • You can use a variable to automatically provide the tag value.

  • Defined tags can be used in policy statements.
