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：

我尝试使用 prune 命令删除了约6GB的内容，但问题仍然存在：

  1. docker system prune

使用 k describe deployment 命令查看部署信息如下：

  1. kubectl describe deployment/consumer-deployment

是否还有其他需要查看的内容？

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

  1. docker system prune

Is there anythin else i need to look into it ??

答案1

得分: 0

错误在你提供的附加输出中。

  1.   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

  1.   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.
