@kangzemin Please provide the output of kubectl describe po broker-0-master-0 -n mq, let's check what was wrong. It seems that the pod was killed due to OOM.

@kangzemin IMO configurations in example need to be modified. Please try setting BROKER_MEM to " -Xms1g -Xmx1g -Xmn512m " in the following files: https://github.com/apache/rocketmq-operator/blob/f904c6604a58880d83444b25c4a331092737770a/example/rocketmq_v1alpha1_broker_cr.yaml#L21
