How does Payara Micro with active Hazelcast handle a killed pod?
Let’s say there are 3 pods running with Payara Micro. Kubernetes kills one of them, and no graceful shutdown was configured.
A common issue occurs: the remaining pods still consider the killed pod as active, which leads to errors.
Shouldn’t the cluster handle this situation automatically?
Or is there something I need to configure manually?
Thank you.
Greetings @Pedro, apologies for the late reply on your question. To answer your question, when running on a Payara Micro cluster in Kubernetes, as long as the Payara Micro instances are correctly configured using the kubernetesdiscovery mode and the requirements in the K8S cluster are set correctly, when pods are killed by the cluster their corresponding Payara Micro instances should leave the DataGrid/Hazelcast cluster in tandem.
