RabbitMQ配置文件在Kubernetes部署中无法解决

Question

我正在尝试在Kubernetes集群上部署RabbitMQ，并使用initcontainer从ConfigMap复制文件。但是，POD处于运行状态后，该文件未复制。

[最初，我尝试不使用initcontainer，但出现类似“ touch：无法触摸'/etc/rabbitmq/rabbitmq.conf'：只读文件系统。”]的错误

文件“ definitions.json”应复制到/ etc / reabbitmq文件夹。我遵循了“ Kubernetes deployment read-only filesystem error”。但是问题没有解决。

您可以检查/ etc / rabbitmq /的权限。用户是否有权将文件复制到上面的位置？
