When trying to install AMQ 7 operator via command line, it failed to pull the operator image. 

At the operator.yaml 
 
147           value: "false"                                                
148         image: registry.redhat.io/amq7/amq-broker-rhel8-operator:7.10-9 
149         livenessProbe:          

It should be 7.10-11 [1] 

147           value: "false"                                                
148         image: registry.redhat.io/amq7/amq-broker-rhel8-operator:7.10-11
149         livenessProbe:          

So, change the operator.yaml line 148

Notice there are 7.10-11, 7.10-10 just not 7.10-9
