Since https://github.com/openshift/operator-framework-olm/pull/435 merged, public catalogs have --cache-dir and precomputed caches.

oc-mirror 4.14 and 4.13 writes catalog with --cache-dir in CMD
oc-mirror catalogs crashloop complaining that the cache is invalid

4.14
4.13

always

1.Download oc-mirror 4.13 or 4.14
2.Mirror registry.redhat.io/redhat/redhat-operator-registry:4.12 with oc-mirror to a registry
3.Try to install an operator on a disconnected cluster from that mirrored registry

[root@localhost 2633]# oc get pod
NAME                                    READY   STATUS             RESTARTS     AGE

oc logs -f po/redhat-operator-index-t7svb

I can install and upgrade operators from a mirrored catalog
