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。
