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:
nodeName
或nodeSelector
进行简单调度,使用nodeAffinity
、podAffinity
和podAntiAffinity
实现复杂调度规则。apiVersion: v1
kind: ResourceQuota
metadata:
name: resource-test
spec:
hard:
pods: 50
requests.cpu: "1"
requests.memory: "1Gi"
limits.cpu: "2"
limits.memory: "2Gi"
kubectl apply -f resource-quota.yaml -n rq-test
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"
kubectl apply -f nginx.yaml -n rq-test
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。建议在实际部署前,参考Kubernetes官方文档进行详细的规划和测试。
