9.4.2. Setting tag expiration from a Dockerfile

9.4.2. Setting tag expiration from a Dockerfile

You can add a label, for example, quay.expires-after=20h to an image tag by using the docker label command to cause the tag to automatically expire after the time that is indicated. The following values for hours, days, or weeks are accepted:

1h
2d
3w

Expiration begins from the time that the image is pushed to the registry.

Procedure

Enter the following docker label command to add a label to the desired image tag. The label should be in the format quay.expires-after=20h to indicate that the tag should expire after 20 hours. Replace 20h with the desired expiration time. For example:
```
$ docker label quay.expires-after=20h quay-server.example.com/quayadmin/<image>:<tag>
```
