22.4.2. 볼륨 플러그인 사용
Pod 구성을 생성할 때
spec.volumes.downwardAPI.items필드를 사용하여spec.resources필드에 해당하는 원하는 리소스를 설명합니다..... spec: containers: - name: client-container image: gcr.io/google_containers/busybox:1.24 command: ["sh", "-c", "while true; do echo; if [[ -e /etc/cpu_limit ]]; then cat /etc/cpu_limit; fi; if [[ -e /etc/cpu_request ]]; then cat /etc/cpu_request; fi; if [[ -e /etc/mem_limit ]]; then cat /etc/mem_limit; fi; if [[ -e /etc/mem_request ]]; then cat /etc/mem_request; fi; sleep 5; done"] resources: requests: memory: "32Mi" cpu: "125m" limits: memory: "64Mi" cpu: "250m" volumeMounts: - name: podinfo mountPath: /etc readOnly: false volumes: - name: podinfo downwardAPI: items: - path: "cpu_limit" resourceFieldRef: containerName: client-container resource: limits.cpu - path: "cpu_request" resourceFieldRef: containerName: client-container resource: requests.cpu - path: "mem_limit" resourceFieldRef: containerName: client-container resource: limits.memory - path: "mem_request" resourceFieldRef: containerName: client-container resource: requests.memory ....리소스 제한이 컨테이너 구성에 포함되지 않은 경우 Downward API의 기본값은 노드의 CPU 및 메모리 할당 가능 값으로 설정됩니다.
volume-pod.yaml파일에서 Pod를 생성합니다.$ oc create -f volume-pod.yaml
