Cost Optimization · Container Registry · Azure.ACR.Retention

Use a retention policy to cleanup untagged manifests.

Description#

Retention policy is a configurable option of Premium Azure Container Registry (ACR). When a retention policy is configured, untagged manifests in the registry are automatically deleted. A manifest is untagged when a more recent image is pushed using the same tag. i.e. latest.

The retention policy (in days) can be set to 0-365. The default is 7 days.

Recommendation#

Consider enabling a retention policy for untagged manifests.

Notes#

Retention policies for Azure Container Registry is currently in preview.
