我正在尝试在Kubernetes集群中设置我的mosquitto服务器,并且某种程度上我遇到了以下错误,但我不知道为什么。 有人可以帮我吗?

错误:

问题在于端口1883上的侦听器,可以确定,因为日志尚未到达9001侦听器。

此问题最有可能是因为mosquitto无法解析主机名mosquitto的IP地址。传递主机名时,该名称必须解析为有效的IP地址。 this最近的答案中讨论了相同的问题。也可能是mosquitto解析为未绑定到实际计算机上任何接口的地址(例如,如果正在使用地址转换)。

对于9001侦听器,除了传递0.0.0.0之外,您不能仅包含绑定地址,并且默认值是在所有接口上侦听。
