kubernetes - Kubernetes CronJob 未退出

问题描述

我在 kubernetes 中运行一个 cronjob。Cronjob 已启动但未退出。pod 的状态总是在RUNNING。下面是日志

kubectl get pods
cronjob-1623253800-xnwwx   1/1     Running            0          13h

当我描述下面的工作时，会注意到

kubectl describe job cronjob-1623300120

  Normal  SuccessfulCreate  13h  job-controller  Created pod: cronjob-1623300120

我注意到 Pod 状态：1 运行/0 成功/0 失败。这意味着当代码返回零时，作业成功/失败。那是对的吗？。

当我使用执行命令进入 pod

kubectl exec --stdin --tty cronjob-1623253800-xnwwx -n cronjob -- /bin/bash

root@cronjob-1623253800-xnwwx:/# ps ax| grep python
    1 ?        Ssl    0:01 python -m sfit.src.app
   18 pts/0    S+     0:00 grep python

我发现python进程仍在运行。这是代码问题死锁还是其他问题。

@KrishnaChaurasia。我在我的系统中运行 docker 映像。我的 python 代码中有一些错误。但它是退出错误。但是在 kubernetes 中它没有退出也没有停止

docker run xxxxx/cronjob:1    
 File "/usr/local/lib/python3.8/site-packages/azure/core/pipeline/transport/_requests_basic.py", line 261, in send
        raise error
    azure.core.exceptions.ServiceRequestError: <urllib3.connection.HTTPSConnection object at 0x7f113f6480a0>: Failed to establish a new connection: [Errno -2] Name or service not known
