minikube上的RabbitMQ群集Kubernetes运算符

我正在尝试使用以下命令在Minikube上设置RabbitMQ：

尝试连接持久卷时，出现以下错误：

$ kubectl logs -f rabbitmq-rabbitmq-server-0

要在minikube上复制此版本，请执行以下操作：

安装rabbitmq操作符：

kubectl应用-f”https://github.com/rabbitmq/cluster-operator/releases/latest/download/cluster-operator.yml"

应用上面的清单文件

运行

kubectl get po

会显示一个名为

rabbitmq-rabbitmq-server-0

的pod

运行

kubectl logs-f rabbitmq-rabbitmq-server-0查看日志会显示上述错误

正如我在评论中所建议的，您可以通过以下方式解决此问题：

minikube ssh -- sudo chmod g+w /mnt/app/rabbitmq/

回答你的问题:

有没有一种方法可以将其添加到清单文件中，而不必手动执行

您可以重写rabbitmq statefulset清单字段，将initContainer命令脚本中的最后一行从

chgrp 999/var/lib/rabbitmq/mnesia/

更改为：

chown 999:999/var/lib/rabbitmq/mnesia/

完整的RabbitmqCluster yaml清单如下所示：

当我尝试附加持久卷时

-您没有提到如何附加它。最好我需要信息如何复制您的问题。请提供一步一步的说明来复制它。嗨，马特！谢谢你的帮助。对不起，我对k8s还是新手。我假设我使用hostPath声明PersistentVolume就是如何附加它的；否则我恐怕不明白你的问题。我附上了关于如何重现该问题的步骤。如果您需要任何进一步的详细信息，请告诉我。运行

minikube ssh--sudo chmod g+w/mnt/app/rabbitmq/

，并告诉我它是否解决了问题it@Matt谢谢你，这真的奏效了！有没有一种方法可以将其添加到清单文件中，而不必手动执行？非常感谢！
