Repo description

This Repo has the following two functions:

• monitor kubernetes
• kubernetes custom hpa monitor

How to monitor Aks/K8S

TIPS: The metrics-server is deployed by default in the aks cluster, and there is no need to deploy metrics-server again in the azure environment.

kubectl apply -f ./namespaces.yaml
kubectl apply -f ./node-exporter.yaml
kubectl apply -f ./metrics-server/0.3.6/ 
kubectl apply -f ./kube-state-metrics/
kubectl aply -f ./prometheus/

Aks/K8S HPA

Customize monitoring indicators through Prometheus adaptor:

https://github.com/stefanprodan/k8s-prom-hpa

How to depoy it:

We still need to perform the steps of deploying prometheus above, and perform the following steps after completion:

make certs  #create secret
kubectl apply -f ./custom-metrics-api/

Prometheus federation

How does external prometheus grab monitor data of k8s-prometheus?

The prometheus pod is already running in the k8s cluster, and external access is provided through nodeport, we only need to configure remote crawling:

  - job_name: 'kubernetes-cluster'
    scrape_interval: 30s
    honor_labels: true
    metrics_path: '/federate'
    params:
      'match[]':
        - '{job=~"kubernetes-.*"}'
    static_configs:
      - targets:
        - k8s1-node1-ip:30090
        - k8s1-node2-ip:30090
        labels:
          k8scluster: noprod-cluster
          resourcetype: 'azure-paas'
          department: 'BU1'
      - targets:
        - k8s2-node1-ip:30090
        - k8s2-node2-ip:30090
        labels:
          k8scluster: prod-cluster
          environment: 'production'
          department: 'BU1'
