k8s中怎么部署prometheus监控pod

在Kubernetes（k8s）中部署Prometheus监控Pod，可以按照以下步骤进行：

1、创建Prometheus配置文件

创建一个名为prometheusconfigmap.yaml的配置文件，内容如下：

apiVersion: v1 kind: ConfigMap metadata: name: prometheusconfig data: prometheus.yml: | global: scrape_interval: 15s evaluation_interval: 15s scrape_configs: job_name: kubernetesapiservers kubernetes_sd_configs: role: endpoints scheme: https tls_config: ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token relabel_configs: source_labels: [__meta_kubernetes_namespace, __meta_kubernetes_service_name, __meta_kubernetes_endpoint_port_name] action: keep regex: default;kubernetes;https job_name: kubernetesnodes kubernetes_sd_configs: role: node scheme: https tls_config: ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token relabel_configs: action: labelmap regex: __meta_kubernetes_node_label_(.+)

2、创建Prometheus部署文件

接下来，创建一个名为prometheusdeployment.yaml的部署文件，内容如下：

apiVersion: apps/v1 kind: Deployment metadata: name: prometheus spec: replicas: 1 selector: matchLabels: app: prometheus template: metadata: labels: app: prometheus spec: containers: name: prometheus image: prom/prometheus:v2.30.3 args: "config.file=/etc/prometheus/prometheus.yml" "storage.tsdb.path=/prometheus" ports: containerPort: 9090 volumeMounts: name: prometheusconfigvolume mountPath: /etc/prometheus name: prometheusstoragevolume mountPath: /prometheus volumes: name: prometheusconfigvolume configMap: name: prometheusconfig name: prometheusstoragevolume emptyDir: {}

3、创建Prometheus服务文件

创建一个名为prometheusservice.yaml的服务文件，内容如下：

apiVersion: v1 kind: Service metadata: name: prometheus spec: type: NodePort selector: app: prometheus ports: protocol: TCP port: 9090 targetPort: 9090 nodePort: 30000

4、应用配置文件到Kubernetes集群

使用kubectl命令将上述配置文件应用到Kubernetes集群：

kubectl apply f prometheusconfigmap.yaml f prometheusdeployment.yaml f prometheusservice.yaml

5、查看Prometheus运行状态和访问地址

使用以下命令查看Prometheus的运行状态和访问地址：

kubectl get pods l app=prometheus o wide n default # 查看Prometheus运行状态和IP地址等信息 kubectl describe service prometheus # 查看Prometheus服务的详细信息，包括NodePort等访问地址信息
