ruby-on-rails - GKE kubernetes delay_job pod 日志

Question

我有一个具有以下内容的部署对象 rake jobs:work命令:

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"]

当我跑 kubectl logs我什么也得不到。我如何获得 rake jobs:work输出显示在 kubectl logs ?即如果直接在 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

我希望在我运行时显示 kubectl logs

我需要添加一个初始化程序:config/initializers/delayed_job.rb并将 worker 的记录器设置为标准输出，如下所示:
Delayed::Worker.logger = Logger.new(STDOUT)
