Я пока не понимаю какие там могут быть проблемы с отказоустойчивостью. Харбор это прослойка над обычным регистри
беда. У меня этот registry от докера (который docker.io/registry:2) периодически 502 отдает по еще не выясненым причинам. Как раз в сторону harbor смотрел
Issue Help : We have around 5000 repos in our registry. What we are seeing now is - When the images are pushed, the entries are being made in the Artifacts table, Blob table, project table but NOT in the Repository Table. As a result user do not see new repos under their project and associated image and tags information. However, if we construct the REST URL for image and tag that was pushed, Harbor UI shows the details properly. So ONLY entry in the repository table is missing since today.
