Prometheus Postgres Exporter

Prometheus exporter for PostgreSQL server metrics.

This chart bootstraps a prometheus postgres exporter deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

• Kubernetes 1.16+
• Helm 3+

Get Repo Info

helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo update

See helm repo for command documentation.

Install Chart

helm install [RELEASE_NAME] prometheus-community/prometheus-postgres-exporter

See configuration below.

See helm install for command documentation.

Uninstall Chart

helm uninstall [RELEASE_NAME]

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

See helm uninstall for command documentation.

Upgrading

To 2.0.0

The primary change in 2.0.0 is the Chart API from v1 to v2. This now requires Helm3. Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments. Use the workaround below to upgrade from versions previous to 2.0.0. The following example assumes that the release name is prometheus-postgres-exporter:

kubectl patch deployment prometheus-postgres-exporter --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'

Other minor version upgrade

helm upgrade [RELEASE_NAME] [CHART] --install

See helm upgrade for command documentation.

Configuring

See Customizing the Chart Before Installing. To see all configurable options with detailed comments, visit the chart's values.yaml, or run these configuration commands:
