Cortex can pull owners from your Git provider, identity provider, HR system, ITSM tool, on-call tool, or cloud tags. This page compares every ownership source in one place so you can choose a source of truth and write x-cortex-owners blocks correctly. If you’re new to ownership in Cortex, start with How ownership works. For help choosing a source, see Ownership best practices.

Sources that use x-cortex-owners

For these sources, reference the provider’s team or group in the entity descriptor with type: group:
Workday teams are imported as Cortex teams, so you reference them by their Cortex tag with provider: CORTEX.

Sources that use cloud tags

AWS and Azure Resources don’t use x-cortex-owners. Instead, Cortex reads an ownership tag on each cloud resource and matches its value to a Cortex team’s x-cortex-tag. By default, the tag key is owner, and you can customize it in each integration’s settings. Because the tag points to a Cortex team, you don’t need identity mappings for this step.
