如何解决 Kubernetes 部署警告？

Question

$ kubectl version --short
Client Version: v1.20.2
Server Version: v1.19.6-eks-49a6c0

我有以下部署清单

apiVersion: apps/v1
kind: Deployment
metadata:
  name: stats-service
  namespace: my-system
  labels:
    app: stats-service
spec:
  selector:
    matchLabels:
      app: stats-service
  template:
    metadata:
      labels:
        app: stats-service
    spec:
      containers:
      - name: stats-service
        image: 0123456789.dkr.ecr.us-east-1.amazonaws.com/stats-service:3.12.1
        resources:
          requests:
            memory: "1024m"
            cpu: "512m"
          limits:
            memory: "2048m"
            cpu: "1024m"
        ports:
        - name: http
          containerPort: 5000
          protocol: TCP
       startupProbe:
          httpGet:
            path: /manage/health
            port: 5000
          failureThreshold: 30
          periodSeconds: 10
        livenessProbe:
          httpGet:
            path: /manage/health
            port: 5000
          failureThreshold: 3
          periodSeconds: 10
        readinessProbe:
          httpGet:
            path: /manage/health
            port: 5000
          failureThreshold: 6
          periodSeconds: 10
        env:
        - name: SPRING_PROFILES_ACTIVE
          value: test
        - name: JAVA_OPTS
          value: "my_java_opts"

当我应用它时，我收到以下警告，并且 Pod 从未创建。这是什么意思，如何解决？就我而言，我是运行和 EKS Fargate（仅）集群。谢谢！

$ kubectl describe pod stats-service-797784dfd5-tvh84
...
  Warning  FailedCreatePodSandBox  12s   kubelet            Failed to create pod sandbox: rpc error: code = Unknown desc = failed to create containerd task: OCI runtime create failed: container_linux.go:349: starting container process caused "process_linux.go:319: getting the final child's pid from pipe caused \"read init-p: connection reset by peer\"": unknown

备注：

似乎警告与 spec.template.spec.containers.resources.limits 块有关。如果我删除它，就会创建 Pod。
我在网上看到的很多解决方案都说要重置Docker，这显然不适用于我。

您对资源使用了错误的符号。根据 Meaning of memory:

Limits and requests for memory are measured in bytes. You can express memory as a plain integer or as a fixed-point number using one of these suffixes: E, P, T, G, M, K. You can also use the power-of-two equivalents: Ei, Pi, Ti, Gi, Mi, Ki.

如果你愿意，

要求：
- 1GB 内存
- 0.5 vCPU/Core
限制：
- 2GB 内存
- 1 vCPU/Core

这应该有效：

        resources:
          requests:
            memory: "1G"
            cpu: "0.5"
          limits:
            memory: "2G"
            cpu: "1"

以下是等效的，但使用不同的符号：

        resources:
          requests:
            memory: "1024M"
            cpu: "500m"
          limits:
            memory: "2048M"
            cpu: "1000m"

请注意，上面的示例使用 M 作为内存，而不是 m。
