nsc registry policy instead.
nsc registry default-expiration makes it possible to query and modify the configured default expiration that is applied to new images uploaded to nscr.io.
By default, images stored in nscr.io never expire. The default expiration duration needs to be at least 4 hours.
Once an image expires it can no longer be accessed and the underlying blobs are automatically deleted.
Note: the default expiration only applies to images created after configuring the value.
In case you would like to apply the expiration retroactively, please reach out to our support.
