The repo component consists of three parts: repo database, repo storage and repo service. The user of repo communicates through repo service which is the micro service of OpenPitrix. The repo service manages the lifecycle of repos such as create a repo, update a repo etc. The repo table stores the metedata of each repo. Please check the database design. The repos can be from multiple sites. Actually repo storage is not part of the repo component. We can use any repo on the internet such as Helm repo https://kubernetes-charts.storage.googleapis.com.
