Mandate background
The so-called private warehouse, which is in local (LAN) is similar to a public warehouse build something, build a good following, we can submit to mirror the private warehouse. We both use to run our project Docker image, but also to avoid the public to come and collect the warehouse to take the risk of being exposed to; use Docker Registry quickly build private mirroring warehouse .
