Front-end "FailedMount" in quickstart Camel K: Event Streaming Example

On OCP 4.9, with [Camel K 1.6.1|ENTESB-17832], AMQ Broker for RHEL 8 (Multiarch), 7.9.1-opr-2, 7.x channel; AMQ Streams, 1.8.3; I followed manually steps in quickstart Camel K: Event Streaming Example. I encountered problem in step Running the Front-end

URL=$(oc get ksvc timeline-bridge -o 'jsonpath={.status.url}') ; cat ./front-end/Dockerfile| oc new-build --docker-image="registry.access.redhat.com/rhscl/httpd-24-rhel7:latest" --to=front-end --build-arg="URL=$URL" -D -

$ oc get pods
front-end-1-build                                   0/1     Error       0          20m

So I can't complete the quickstart - following step "oc apply -f front-end/front-end.yaml" creates pod in state "ErrImagePull", and on produced URL is "Application not available" (viz [FUSEQE-13889]).

Integrations (also earthquake-bridge, timeline-bridge) were running correctly, I used default values in application.properties:

kafka.bootstrap.address=event-streaming-kafka-cluster-kafka-bootstrap.event-streaming-kafka-cluster:9092
