Prometheus Docker Hub Exporter

Exposes metrics of container pulls and stars from the Docker Hub API, to a Prometheus compatible endpoint. The exporter is capable of pulling down stats for individual images, or for orgs or users from DockerHub. This is based on the un-documented V2 Docker Hub API.

Configuration

The image is setup to take parameters from environment variables or flags:

The available environment variables are:

• BIND_PORT The port you wish to run the container on, defaults to 9170
• ORGS The docker hub organizations you wish to monitor, expected in the format "org1, org2" (Also works for users)
• IMAGES The images you wish to monitor, expected in the format "user/image1, user/image2". Can be across different dockerhub users. If empty -> all images

Below is a list of the available flags. You can also find this list by using the --help flag.

• images Images you wish to monitor: expected format 'user/image1,user/image2'
• listen-address Address on which to expose metrics and web interface. (default ":9170")
• organisations Organisations/Users you wish to monitor: expected format 'org1,org2'
• telemetry-path Path under which to expose metrics. (default "/metrics")

Install and deploy

Run manually from Docker Hub:

docker run -d --restart=always -p 9170:9170 badsmoke/docker-hub-exporter -listen-address=:9170 -images="badsmoke/mjpg-streamer,badsmoke/quay" -organisations="badsmoke"

get all images from organisations

docker run -d --restart=always -p 9170:9170 badsmoke/docker-hub-exporter -listen-address=:9170 -organisations="badsmoke"
