Compatible Registries

Cloud Native Application Bundles are very new, and support for storing anything other than container images in a registry is inconsistent. The community has tested a bunch of registries for compatibility with CNAB and so far here is what we have found.

There is an explicit verification using Porter because we use specific libraries, such as cnab-to-oci, and this helps us communicate confidently that we’ve tested out a particular registry and know that it will work for you.
