无法从另一个Pod K8s连接RabbitMQ Pod

如何解决无法从另一个Pod K8s连接RabbitMQ Pod

我目前正在尝试部署一个应用程序来连接Rabbitmq。

应用程序和Rabbitmq位于同一群集节点上的不同容器中。

我无法通过服务名或群集IP连接到RabbitMQ。

您对这个问题有任何想法吗？

这是Rabbitmq_deployment.yaml

这是在应用程序上连接Rabbitmq的配置

"QueueConfig": {
        "HostName": "rabbitmq-svc","UserName": "guest","Pwd": "guest","VirtualHost": "/","Port": 5672,}

这里是kubectl -n test describe avc rabbitmq-svc

的输出
