The goal of this feature request is to devise a scenario and create documentation regarding multi-cluster deployment of Quay on geographically distant OpenShift clusters so that all Quay clusters function as one global registry by means of the Quay operator. Issues that might arise for this implementation:

1) reconciliation and syncing of config files between clusters
2) upgrading the whole cluster between minor and major versions
3) possible issues regarding access to Clair and builders

Currently, as per documentation the only way to deploy Quay on OpenShift is via the operator since we removed all explicit YAML files from the docs (documentation for Quay 3.3 contains these YAML files). Manual deployment by crafting YAML files with proper control from an outside source would allow seamless deployments over multiple sites with no fear of reconciliation, but it also removes the possibility of easy upgrades which the operator controls.

Thanks!
