Section Number and Name: 
24.2. CONTAINER HEALTH CHECKS USING PROBES

 HTTP Checks

Describe the issue: 

 Here's the downstream descriptions of error codes:
  The check is deemed successful if the hook returns with 200 or 399.

 Here's the upstream description however (which is linked on the same page):
   If it returns between 200 and 399, it is considered success, failure otherwise.

 So any status code in the range from 200 to 399 is deemed "success" by kubernetes.

Suggestions for improvement: 

Fix the sentence as all 2xx and 3xx codes are "success" and there seems to be a typo.
