Description

• ServiceNow offers support for Kubernetes discovery and the procedure is explained in Kubernetes discovery document. However, even after following the steps, the Kubernetes resources cannot be discovered. 
• The problem observed here is with Credential configuration. The expected outcome of  command is as below.

• However, on executing the command, the output we see is as below.

• This article will demonstrate on the investigations and probable use cases, hence in future, if a similar error occurs then this can be one of the cause and worth trying to fix.

Cause

• This issue with the unsupported Kubernetes configuration.

Resolution

 

• ServiceNow Kubernetes Discovery supports credential configuration using Username and password as well as using bearer token. Thus to make it work, we need to have valid UserName details.  
• In order to get the username and password details, we recommend using kubectl config view command to get the correct user details as per the screenshot in the document.
• If, in an environment, kubectl config view command is not showing the expected details then need to get the "supported" command from Kubernetes admin to fetch username and password details.
