Introduction

1.Find Resources

(1) Identify Resources

• resource id: <namespace>/<controller_type>/<controller_name>/<container_name>

  • why this form:
    • use controller can trace the utilization of an application rather than a pod

• resource categories

  • common controllers: Deployment, StatefulSet, DaemonSet
  • cron job (TODO)
    • jobs run periodically

(2) Conditions

• set different conditions for different envs to find qualified resources

• test env

  • cpu: 95 quantile < requests
  • memory: max < requests
  • duration: 1 week

2.Give Recommendations

• resource recommendation
  • cpu minimum: 10m
  • memory minimum: 10M
• resource score
  • score= (cpu_reserved + memory_reserved / (1024*1024*1024*2)) * replicas
    • cpu weight is 1, memory weight is 1/(1024*1024*1024*2) (refer to 1C/2G)
