访问cron作业kubernetes中的日志 [英] access logs in cron jobs kubernetes

问题描述

我在kubernetes中运行cron作业，作业成功完成，我将输出记录到日志文件中(路径:存储/日志)，但是由于容器已完成而无法访问该文件，这是我的工作Yaml.

im running cron job in kubernetes, jobs completes successfully and i log output to log file inside(path: storage/logs) but i cannot access that file due to container is in completed here is my job yaml.

apiVersion: v1
items:
- apiVersion: batch/v1beta1
  kind: CronJob
  metadata:
    labels:
      chart: cronjobs-0.1.0
    name: cron-cronjob1
    namespace: default
  spec:
    concurrencyPolicy: Forbid
    failedJobsHistoryLimit: 1
    jobTemplate:      
      spec:
        template:
          metadata:          
            labels:
              app: cron
              cron: cronjob1
          spec:
            containers:
            - args:
              - /usr/local/bin/php
              - -c
              - /var/www/html/artisan bulk:import
              env:
              - name: DB_CONNECTION
                value: postgres
              - name: DB_HOST
                value: postgres
              - name: DB_PORT
                value: "5432"
              - name: DB_DATABASE
                value: xxx
              - name: DB_USERNAME
                value: xxx
              - name: DB_PASSWORD
                value: xxxx
              - name: APP_KEY
                value: xxxxx
              image: registry.xxxxx.com/xxxx:2ecb785-e927977
              imagePullPolicy: IfNotPresent
              name: cronjob1
              ports:
              - containerPort: 80
                name: http
                protocol: TCP              
            imagePullSecrets:
            - name: xxxxx
            restartPolicy: OnFailure          
            terminationGracePeriodSeconds: 30
    schedule: '* * * * *'
    successfulJobsHistoryLimit: 3

反正我可以在kubectl log命令或其他替代方法上显示我的日志文件内容吗?

is there anyway i can get my log file content display on kubectl log command or other alternatives?

推荐答案

我想您知道，当您拥有successfulJobsHistoryLimit: 3时，豆荚就被保存在身边.大概您的意思是您的日志记录将记录到文件而不是stdout，因此您不会在kubectl logs中看到它.如果是这样，也许您也可以登录到stdout或在作业中添加一些内容以最后记录文件的内容，

I guess you know that the pod is kept around as you have successfulJobsHistoryLimit: 3. Presumably your point is that your logging is going logged to a file and not stdout and so you don't see it with kubectl logs. If so maybe you could also log to stdout or put something into the job to log the content of the file at the end, for example in a PreStop hook.
