    Description

       User story:

       As a user, I want to monitor my Kubernetes cluster to be able to see the current status of my cluster.

      UI/UX: designer

       

      Acceptance criteria  

      • User able to register K8s cluster into PMM  using UI / API
      • User able to see metrics about NODES in K8s cluster  (Autodiscovery? )
      • User able to see Container metrics (Autodiscovery? )

      Out of scope: 

      • K8s Dashboards  
      • Containers and Services are presented on the same dashboards  as bare-metal services and nodes so the user able to see DB  metrics together with Node/container metrics 
      • Adding standard label  for K8s
      • CLI for DBaaS

      Suggested implementation: 

       Run Victoriametrics operator

      1. Setup crds and operator

      3. Run VMAgent
        1. Download https://github.com/VictoriaMetrics/operator/blob/master/config/examples/vmagent.yaml
        1. Replace `remoteWrite` field with a path to our VM Service
        2. Apply
      1. Apply vmnodescrape to collect node metrics

      How to test: 

      1. Setup public address in settings
      2. register K8s cluster 
      3. check advanced data exploration dashboard for cadvisor related new metrics.

      Questions:

      1. How we will add kubernetes cluster to monitoring?
      2. Is it ok to request PMM public server address to be able to setup monitoring?
