Tags and metadata

Tags and metadata

Tags and metadata can both be used to help describe an instance or configure its properties.

Tags and metadata differ in how they're used within Triton, how they're managed via the APIs, and how they're best used.

Data Type


Mange with

Accessible within instances


Identify an instance externally and use as instance selection criteria

Portal, CloudAPI



Insert data within an instance, such as environment variables

Portal, CloudAPI, metadata client (mdata-* commands)


To create or modify tags with triton, the user must have the proper permissions and keys. Metadata can be modified within an instance without the need for permissions or keys.
