docker - 为什么Pod即使成功运行也会返回Error或ExitCode:0？

一键式Pod有两种状态代码，可从API或命令运行:
kubectl run --restart=Never --image test:v0.1 ...。

pods 将输出文件生成到NFS服务器，并且我已经成功获取了文件。
kubectl get pods -ao wide:

NAME       READY     STATUS       RESTARTS   AGE

test-99    0/1       ExitCode:0   0          23m       192.168.1.43

ExitCode:0 pod的描述:

Name:                           test-99
Namespace:                      default
Image(s):                       test:v0.1
Node:                           192.168.1.43/192.168.1.43
Status:                         Succeeded
Replication Controllers:        <none>
Containers:
  test:
    State:              Terminated
      Exit Code:        0
    Ready:              False
    Restart Count:      0

Error pod的描述:

Name:                           test-98
Namespace:                      default
Image(s):                       test:v0.1
Node:                           192.168.1.46/192.168.1.46
Status:                         Succeeded
Replication Controllers:        <none>
Containers:
  test:
    State:              Terminated
      Reason:           Error
      Exit Code:        0
    Ready:              False
    Restart Count:      0

他们的NFS卷:

Volumes:
  input:
    Type:       NFS (an NFS mount that lasts the lifetime of a pod)
    Server:     192.168.1.46
    Path:       /srv/nfs4/input
    ReadOnly:   false
  output:
    Type:       NFS (an NFS mount that lasts the lifetime of a pod)
    Server:     192.168.1.46
    Path:       /srv/nfs4/output
    ReadOnly:   false
  default-token-nmviv:
    Type:       Secret (a secret that should populate this volume)
    SecretName: default-token-nmviv

kubectl logs不返回任何内容，因为容器仅生成输出文件。

提前致谢!

最佳答案

ExitCode 0表示它正常终止

如果通过管道传输到另一个进程，则可以使用退出代码，因此该进程知道下一步该怎么做(如果上一个进程失败，请执行其他操作，否则对传递的数据进行某些操作...)
