A Virtual Repository defined in Artifactory aggregates packages from both local and remote repositories.
This allows you to access both locally hosted Alpine Linux packages and remote proxied Alpine Linux repositories from a single URL defined for the Virtual Repository.
To define a virtual Alpine Linux repository, do the following:
Create a Virtual Repository, and set the Package Type to Alpine.
Select the underlying local and remote Alpine Linux repositories to include in the Basic settings tab.
You can select an RSA key-pair from the list to sign the Alpine Linux packages.
RSA Key-pair
The RSA key-pair defined for the virtual repository will be used to sign the virtual index file. In case local repositories are defined with RSA key-pairs, these keys will be ignored.
