为什么pods返回Error或ExitCode：0即使它们成功运行？

Question

有两种状态码的一次性吊舱，从API或命令运行：

kubectl run --restart=Never --image test:v0.1 ...。

pod生成输出文件到NFS服务器，并且我已经成功获取文件。

kubectl get pods -ao wide：

NAME  READY  STATUS  RESTARTS AGE  
test-90 0/1  ExitCode:0 0   23m  192.168.1.43 
test-91 0/1  ExitCode:0 0   23m  192.168.1.43 
test-92 0/1  ExitCode:0 0   23m  192.168.1.43 
test-93 0/1  ExitCode:0 0   23m  192.168.1.43 
test-94 0/1  Error  0   23m  192.168.1.46 
test-95 0/1  Error  0   23m  192.168.1.46 
test-96 0/1  Error  0   23m  192.168.1.46 
test-97 0/1  Error  0   23m  192.168.1.46 
test-98 0/1  Error  0   23m  192.168.1.46 
test-99 0/1  ExitCode:0 0   23m  192.168.1.43 

ExitCode:0荚的描述：

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荚的描述：

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由于容器只产生输出文件而不返回任何值。

在此先感谢！

ExitCode 0意味着它正常终止

退出代码可以使用，如果你管到另一个过程，所以这个过程知道下一步该怎么做（如果以前的进程失败做到这一点，否则做传递的数据东西.. ）
