VMWare_exporter Helm Chart

TL;DR;

$ helm install kremers/vmware-exporter

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release kremers/vmware-exporter

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

vsphere.user User for vcenter login user
vsphere.password Password for vcenter login na
vsphere.existingSecret Provide password for vCenter login w/ secret
vsphere.host Hostname or IP for vcenter login vcenter
vsphere.ignoressl User for vcenter user
vsphere.collectors.hosts Collect host metrics true
vsphere.collectors.datastores Collect datastore metrics true
vsphere.collectors.vms Collect vm metrics true
vsphere.sections Add additional configuraiton sections via environment variables []]

Example of vcenter configuration

vsphere:
  user: user
  password: somepassword
  host: vcenter.someCompany.com
  ignoressl: false
  collectors:
    hosts: true
    datastores: true
    vms: true

Sharding the exporter for different vcenter instances

If different tenants are configured that have restricted visibility to specific folders, metrics can be sharded. This will allow a setup like:

Prometheus customer(A) => VMWare exporter customer(A) => VCenter restricted access for customer(A) Prometheus customer(B) => VMWare exporter customer(B) => VCenter restricted access for customer(B)

Some Grafana dashboard, connected to a datasource with mixed content will allow access to the whole underlying datasource with VIEWER privileges.

To enable seperation in the K8S autodiscovery to the following:

podAnnotations:
  yourcustomannotation/scrape: "true"
  yourcustomannotation/port: "9272"
  prometheus.io/scrape: null
  prometheus.io/port: null
  prometheus.io/path: null

The scraping of Prometheus can be configured, adding additionalScrapeConfig parts or replacing prometheus.yml (most common for sharded data):

Parametrize the stable/prometheus chart like in the following example, take care for yourcustomannotation:

serverFiles:
  prometheus.yml:
    rule_files:
    - /etc/config/rules
    - /etc/config/alerts
    scrape_configs:
