The Project Atomic site has had a section dedicated to the Atomic Registry which has been useful for getting a registry up and running as quickly as possible. However, the software powering the quickstart installation has not always kept up with the OpenShift Origin software which powers the actual registry and web UI. This has lead to an increase in users reporting issues in the #atomic Freenode IRC channel. And often it ends with someone pointing to the stand-alone registry documentation that is provided by the OpenShift Origin project.
It turns out that deploying the stand-alone registry on a single Fedora 25 Atomic Host system is quite straight-forward and can quickly provide a usable registry. In this blog post, we’ll deploy a proof-of-concept stand-alone registry on a single node, which will end up using self-signed certificates in the process. In a later blog post, we’ll show you how to setup a stand-alone registry using multiple nodes and your own SSL certificates.
