Problem Description

When using Serverless Inference Platform(SLIP) endpoints, there is a need to use custom headers (key value pair) as prefix to AI model when using the k8sgpt operator within the cluster.

Solution Description

When applying the k8sGPT configuration object using yaml manifest on the cluster, the customheader field under ai will enable the call to the internal SLIP endpoint hosting the various LLM models. The jsonpath where this feature needs to be added is : .spec.ai.customheaders

Benefits

Addition of this feature to the k8sGPT configuration object will fill in the results object with AI recommendations from SLIP endpoints.
