== Setting tag expiration using annotations
88+
89+
You can add an annotation, for example, `quay.expires-after=20h`, to an image tag using the `--annotation` flag when pushing an image to the registry. This annotation causes the tag to automatically expire after the specified time. The annotation can be applies to both image manifests and image indexes. The following values for hours, days, or weeks are accepted:
90+
91+
* `1h`
92+
* `2d`
93+
* `3w`
94+
95+
Expiration begins from the time that the image is pushed to the registry.
