About

This is a simple tool that reads the Docker API and generates Prometheus scrape configs for all Docker configs that have the io.prometheus.scrape_config label set to true.

Usage

usage: prometheus-configs-provider [<flags>]

Flags:
  --[no-]help                Show context-sensitive help (also try --help-long and --help-man).
  --output-dir="/etc/prometheus/configs"  
                             directory for the configs
  --output-ext="yaml"        extension for the configs
  --[no-]keep-existing       keep existing files in output directory
  --evaluation-interval=15s  How frequently to evaluate service configs
  --prometheus-scrape-config-label="io.prometheus.scrape_config"  
                             label to identify prometheus scrape configs
  --[no-]version             Prints current version.
  --[no-]short-version       Print just the version number.

Example

# docker-stack.yml

configs:
  example-scrape-config:
    file: ./example-scrape-config.yaml
    labels:
      - "io.prometheus.scrape_config=true"

With the help of the prometheus-operator/prometheus-operator/tree/main/cmd/prometheus-config-reloader tool, we can automatically reload the Prometheus configuration when the Docker configs are create/update/remove.
