title: Cost of kubernetes readinessProbe tcpSocket
body: <p>I have k8s pods deployed with following readiness probe,</p>
  
  <pre><code>readinessProbe:
    tcpSocket:
      port: 1234
      initialDelaySeconds: 15
      periodSeconds: 2
  </code></pre>
  
  <p>How costly the <code>tcpSocket</code> probe is? </p>
  
  <p>To monitor that port, I want to probe with minimum delay ( like making it 1 sec) </p>
