Ignite-Kubernetes积分中的例外

Question

我是新来的点燃和库伯内特。

<bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.kubernetes.TcpDiscoveryKubernetesIpFinder">
                <property name="namespace" value="ignite"/>
                <property name="serviceName" value="ignite"/>

                                   <property name="AccountToken" value="/data/ignite"/>

                </bean>

请帮我解决如何消除异常。提前道谢。

Answer 1

它正在/var/run/secrets/kubernetes.io/serviceaccount/token中查找服务帐户令牌，但该文件不存在。问题是为什么？

某些命令：

kubectl get serviceaccounts

你应该找一个叫“点燃”的。如果不是，那就是你的问题。

kubectl get serviceaccounts/ignite -o yaml

kubectl get secrets/default-token-wnfp5 -o yaml

kubectl get pods
kubectl get pods/ignite-0 -o yaml

kubectl get clusterrolebinding/ignite

roleref和受试者都应该指向合理的价值观。

Kubernetes有如此多的间接层次，所以很容易错过某个地方的链接。如果您没有意外地错过一个步骤（或者有一些Azure的怪癖），您还可以查看服务帐户文档。
