创建一个configMap

apiVersion: v1
data:
#在此添加需要开启的协议逗号隔开
  enabled_plugins: >-
    [rabbitmq_management,rabbitmq_peer_discovery_k8s,rabbitmq_mqtt,rabbitmq_web_mqtt].
kind: ConfigMap
  name: rabbit-plugins
  namespace: kube-public

复制

也可以通过命令行创建

kubectl create cm rabbit-plugins --from-literal=enabled_plugins="[rabbitmq_management,rabbitmq_peer_discovery_k8s,rabbitmq_mqtt,rabbitmq_web_mqtt]." -n kube-public
复制
