Bug Report
What did you do?
- start minikube
- kubectl create ns operator-sample-tomcat-issue
- kubectl config set-context --current --namespace=operator-sample-tomcat-issue
- mvn clean package
- kubectl apply -f sample-operators/tomcat-operator/target/classes/META-INF/fabric8/tomcats.tomcatoperator.io-v1.yml
- kubectl apply -f sample-operators/tomcat-operator/target/classes/META-INF/fabric8/webapps.tomcatoperator.io-v1.yml
- Start the TomcatOperator main class
- kubectl apply -f sample-operators/tomcat-operator/k8s/tomcat-sample1.yaml
- kubectl apply -f sample-operators/tomcat-operator/k8s/webapp-sample1.yaml
What did you expect to see?
Operator should first deploy two replicas of a tomcat instance and as soon as they become ready deploy the webapp.
What did you see instead? Under which circumstances?
Operator deploys two replicas of a tomcat instance, both became ready, then the WebappReconciler fails with the following exception:
13:40:53.414 ERROR io.javaoperatorsdk.operator.processing.event.ReconciliationDispatcher.handleExecution(ReconciliationDispatcher.java:64) - Error during event processing ExecutionScope{ resource id: ResourceID{name='sample-webapp1', namespace='operator-sample-tomcat-issue'}, version: 498543} failed.

This is due to the fact, that the primaryToSecondaryIndex in io.javaoperatorsdk.operator.processing.event.source.informer.InformerEventSource is empty until the operator restarts.

Possible Solution
Just a workaround: when restarting the operator, everything works fine as long as no new tomcat gets deployed.
For each new tomcat and webapp the same exception rises again until the operator gets restarted.
