release:

https://access.redhat.com/errata/RHBA-2020:5193

See the following Release Notes documentation, which will be updated
shortly for this release, for details about these changes:

This update fixes the following bug among others:

  • Previously, the Image Registry Operator did not generate the httpSecret when it was empty. This caused the httpSecret to not be set correctly. Now, the Operator generates the httpSecret and uses it for all replicas when the configuration file is created. (BZ#1895856)
