## 첫번째 단계 { #first-steps }

아주 간단한 예제를 봅시다. 너무 간단할 것이기에 지금 당장은 유용하지 않을 수 있습니다.

하지만 이를 통해 **의존성 주입** 시스템이 어떻게 작동하는지에 중점을 둘 것입니다.

### 의존성 혹은 "디펜더블" 만들기 { #create-a-dependency-or-dependable }

의존성에 집중해 봅시다.

*경로 처리 함수*가 가질 수 있는 모든 매개변수를 갖는 단순한 함수입니다:

이게 다입니다.

    * Default value for expendable pod priority cutoff in GCP deployment of Cluster Autoscaler changed from 0 to -10.
    * action required: users deploying workloads with priority lower than 0 may want to use priority lower than -10 to avoid triggering scale-up.
