Introduction

This guide helps with set of instruction on how you run this code locally on your laptop and customize the tool

Instructions

• Setup your GOPATH

  export GOPATH=<PATH>
  

• Clone the repository

  git clone https://github.com/pivotal-gss/tanzu-certificate-exporter.git
  cd tanzu-certificate-exporter
  

• Download Dependencies

  go mod vendor
  

• Start your local web server of the code

  go run *.go -a https://<OPSMAN-URL>/ -u prometheus-cert-exporter -w prometheus-cert-exporter-password -e env10 -i 30 -k -p 8080
  

• Install docker if you haven't done so

• Create a prometheus.yml file which content similar to below

  # my global config
  global:
    scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
    evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
    # scrape_timeout is set to the global default (10s).
  
  
  # A scrape configuration containing exactly one endpoint to scrape:
  # Here it's Prometheus itself.
  scrape_configs:
    # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
    - job_name: 'prometheus'
      # metrics_path defaults to '/metrics'
      # scheme defaults to 'http'.
      static_configs:
      - targets: ['127.0.0.1:9090']
  
    - job_name: 'vmware-tanzu-cert-exporter'
      metrics_path: '/metrics'
      static_configs:
      - targets: ['<HOST-IP>:8080']
  

  NOTE: the <HOST-IP> should be physical IP of you laptop not localhost or 127.0.0.1

• Download and run prometheus / grafana docker images

  docker run -d --name prometheus -p 9090:9090 -v `pwd`/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus --config.file=/etc/prometheus/prometheus.yml
  docker run -d --name grafana -p 3000:3000 grafana/grafana
  

• Open browser and navigate to link localhost:9090 to access prometheus UI or localhost:3000 to access Grafana UI
