When I was using RedHat AMQ Broker 7.7 clustered template, it couldn't create StatefulSet so it failed. The reason why it failed was because AMQ_REPLICAS was used as a parameter and it was interpreted as a string, but it should be interpreted as a integer (Link to code).

AMQ_REPLICAS should be in a form of string (for example "2") in the following line because of the JSON properties.

jboss-amq-7-broker-openshift-image/templates/amq-broker-77-persistence-clustered.yaml

Line 225 in 82eb44c

"value": "${AMQ_REPLICAS}"

But it should be in string format in following line. So error occurs in this line because replicas expect integer form, not string ( format should be replicas: 2, not replicas: "2").

Line 274 in 82eb44c

replicas: ${AMQ_REPLICAS}
