SDCICD-1717: update yaml file

[varunraokadaparthi]

Summary

Add support for configuring krkn-ai fitness function query and scenarios via viper config/environment variables. After the krkn-ai container runs in discover mode, the output YAML is automatically updated with user-specified values.

Changes

New Configuration Options

Added two new config keys to KrknAI config:

Config Key	Environment Variable	Description
krknAI.fitnessQuery	KRKN_FITNESS_QUERY	Prometheus query for the fitness function
krknAI.scenarios	KRKN_SCENARIOS	Comma-separated list of scenarios to enable

YAML Update Logic

After runKrknContainer() completes, a new updateKrknConfig() function:

• Reads the krkn-ai.yaml file from the shared directory
• Updates fitness_function.query if KRKN_FITNESS_QUERY is set
• Enables scenarios specified in KRKN_SCENARIOS
• Writes the updated YAML back

Example Usage

Set the fitness function query

export KRKN_FITNESS_QUERY='sum(kube_pod_container_status_restarts_total)'

Set scenarios to enable (comma-separated)

export KRKN_SCENARIOS='pod_scenarios,container_scenarios,node_cpu_hog,node_memory_hog'

• pkg/common/config/config.go - Added FitnessQuery and Scenarios config keys
• pkg/krknai/krknai.go - Added updateKrknConfig() function
