英文:
Kuberentes deployment Pod not getting created
问题
我的Spring应用部署在Kubernetes上，使用Docker Desktop。最初正常工作，但突然之间无法扩展，部署状态停在0/1，没有可用的Pod。
kubectl describe replicaset consumer-deployment-8487d9fdf6^C 显示如下：
Service Account: spring-boot

Kubectl describe nodes 显示如下：

Normal RegisteredNode 33m node-controller Node docker-desktop event: Registered Node docker-desktop in Controller
我尝试使用 prune 命令删除了约6GB的内容，但问题仍然存在：
docker system prune
使用 k describe deployment 命令查看部署信息如下：
kubectl describe deployment/consumer-deployment

是否还有其他需要查看的内容？
英文:
My spring is deployed on kubernetes using docker desktop it was working ok its scale up and down suddenly the deployement get stuck in 0/1 with 0 availebal pod

I tryed prune command and it remove about 6GB but the probleme still persist
docker system prune

错误在你提供的附加输出中。
警告 FailedCreate 94秒（在12分钟内重复18次） replicaset-controller 创建错误：禁止创建 pod："consumer-deployment-8487d9fdf6-"：查找服务帐户default/spring-boot时发生错误：找不到服务帐户"spring-boot"
你正在尝试使用一个可能不存在的服务帐户来创建部署。
英文:
The error is in the appended output you provided
Warning FailedCreate 94s (x18 over 12m) replicaset-controller Error creating: pods "consumer-deployment-8487d9fdf6-" is forbidden: error looking up service account default/spring-boot: serviceaccount "spring-boot" not found
You are trying to create the deployment using a service account which, presumably, doesn't exist.
