Linux kubernetes中容器的参数-c是什么

我已经附上了Kubernetes脚本，其中的参数是-c为什么不需要提供它

apiVersion: apps/v1
kind: Deployment
metadata:
  annotations:
    deployment.kubernetes.io/revision: "1"
  labels:
    run: ngn
  name: ngn
  namespace: default
spec:
  replicas: 1
  selector:
    matchLabels:
      run: ngn
  template:
    metadata:
      labels:
        run: ngn
    spec:
      containers:
      - image: nginx
        imagePullPolicy: Always
        name: ngn
        command: ["/bin/sh"]
        args: ["-c", "while true; do echo hello; sleep 10;done"]

您在这里询问的-c是/bin/sh的一个参数，在您提供的代码段中，它是true；打招呼；睡眠10；作为参数对/bin/sh执行

这有助于我理解

       -c               Read commands from the command_string operand instead of from the standard input.  Special parameter 0 will be set from the
                        command_name operand and the positional parameters ($1, $2, etc.)  set from the remaining argument operands.
