在CentOS上部署和管理Kubernetes(k8s)集群的资源,通常涉及以下几个关键步骤和工具:
创建资源配额:
apiVersion: v1
kind: ResourceQuota
metadata:
  name: resource-test
spec:
  hard:
    pods: 50
    requests.cpu: "1"
    requests.memory: "1Gi"
    limits.cpu: "2"
    limits.memory: "2Gi"
创建Deployment并设置资源限制:
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
  namespace: rq-test
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.15.2
        resources:
          limits:
            memory: "80Mi"
            cpu: "80m"
          requests:
            memory: "60Mi"
            cpu: "40m"
通过上述步骤和工具,可以在CentOS上有效地管理Kubernetes集群的资源,确保集群的高可用性、稳定性和安全性。
