Question

我有一个使用容器docker的springboot应用程序，它的工作原理是，但是现在我想在kubernetes集群中运行。我将这个容器推入dockerhub并工作了

我创建2个文件

我正在使用本教程https://learnk8s.io/blog/scaling-spring-boot-microservices/，但没有minikube，我的公司中有3台服务器

我执行此命令

[webapp@srvapih controle-acesso-api]$ kubectl create -f cta-deployment.yaml 
deployment.extensions/controle-acesso-api created
[webapp@srvapih controle-acesso-api]$ kubectl create -f cta-service.ymal

很奇怪，因为我的节点处于未就绪状态

[webapp@srvapih controle-acesso-api]$ kubectl get nodes
