部署service-level-operator能发挥怎样的作用?
前提:在Kubernetes集群中部署好Prometheus,我这里是采用Prometheus-Operator方式进行部署的。 (1)首先创建RBAC apiVersion: v1 kind: ServiceAccount metadata: name: service-level-operator namespace: monitoring labels: app: service-level-operator component: app
--- apiVersion: rbac.authorization.k8s.io/v1 kind: ClusterRole metadata: name: service-level-operator labels: app: service-level-operator component: app rules: # Register and check CRDs. - apiGroups: - apiextensions.k8s.io resources: - customresourcedefinitions verbs: - "*"
# Operator logic. - apiGroups: - monitoring.spotahome.com resources: - servicelevels - servicelevels/status verbs: - "*"
--- kind: ClusterRoleBinding apiVersion: rbac.authorization.k8s.io/v1 metadata: name: service-level-operator subjects: - kind: ServiceAccount name: service-level-operator namespace: monitoring roleRef: apiGroup: rbac.authorization.k8s.io kind: ClusterRole name: service-level-operator (2)然后创建Deployment apiVersion: apps/v1 kind: Deployment metadata: name: service-level-operator namespace: monitoring labels: app: service-level-operator component: app spec: replicas: 1 selector: matchLabels: app: service-level-operator component: app strategy: rollingUpdate: maxUnavailable: 0 template: metadata: labels: app: service-level-operator component: app spec: serviceAccountName: service-level-operator containers: - name: app imagePullPolicy: Always image: quay.io/spotahome/service-level-operator:latest ports: - containerPort: 8080 name: http protocol: TCP readinessProbe: httpGet: path: /healthz/ready port: http livenessProbe: httpGet: path: /healthz/live port: http resources: limits: cpu: 220m memory: 254Mi requests: cpu: 120m memory: 128Mi (3)创建service apiVersion: v1 kind: Service metadata: name: service-level-operator namespace: monitoring labels: app: service-level-operator component: app spec: ports: - port: 80 protocol: TCP name: http targetPort: http selector: app: service-level-operator component: app (4)创建prometheus serviceMonitor apiVersion: monitoring.coreos.com/v1 kind: ServiceMonitor metadata: name: service-level-operator namespace: monitoring labels: app: service-level-operator component: app prometheus: myprometheus spec: selector: matchLabels: app: service-level-operator component: app namespaceSelector: matchNames: - monitoring endpoints: - port: http interval: 10s (编辑:52站长网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
