【问题描述】：

我有一个带有以下rake jobs:work 命令的部署对象：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: staging-delayed-job-deployment
  namespace: staging
spec:
  template:
    metadata:
      labels:
        env: staging
        name: delayed-job
    spec:
      containers:
        - name: job
          image: gcr.io/ej-gc-dev/redacted:<%= ENV['IMAGE_TAG'] %>
          command: ["/bin/bash", "-l", "-c"]
          args: ["RAILS_ENV=production bundle exec rake jobs:work"]

当我运行kubectl logs 时，我什么也得不到。如何让 rake jobs:work 输出显示在 kubectl logs 中？也就是说，如果直接在 pod 中运行，它会给出如下输出：

[Worker(host:staging-deployment-cc7dc559f-bswvr pid:2381)] Starting job worker
[Worker(host:staging-deployment-cc7dc559f-bswvr pid:2381)] Job UpdateHubspotPersonaJob (id=67) RUNNING

[Worker(host:staging-deployment-cc7dc559f-bswvr pid:2381)] 4 jobs processed at 1.7649 j/s, 0 failed

我希望在我运行 kubectl logs 时显示它

【问题讨论】：

您好，如果您想使用 kubectl logs 访问日志，那么您的 pod 需要将日志发送到 stdout and stderr。

【解决方案1】：

我需要添加一个初始化程序：config/initializers/delayed_job.rb 并将工作人员的记录器设置为标准输出，如下所示：

Delayed::Worker.logger = Logger.new(STDOUT)
