问题背景：使用k8s-job-pod-container时 python的print总是在程序退出时打印，导致无法实时获取容器的日志。

解决方案:

这是因为stdout和stderr流在Python中进行了缓冲。

您可以将环境变量设置为PYTHONUNBUFFERED=1或True

我启动容器是 kubectl create -f xxx.yaml 的方式启动job

所以我只需要修改yaml文件即可

在容器的env参数中 添加 PYTHONUNBUFFERED=“1”

apiVersion: batch/v1
kind: Job
metadata:
  name: "$container_id"
spec:
  completions: 1
  template: # as the same in pod.yaml
    metadata:
      labels:
        name: "$container_id"
    spec:
      restartPolicy: Never
      containers:  # describe how to start this container and set the env and volume
        - name: wind-auto-analy
          image: 
          imagePullPolicy: IfNotPresent
          env:
            - name: PYTHONUNBUFFERED
              value: "1"
          ports:
            - containerPort: 8006
