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.
The image is setup to take parameters from environment variables or flags:
The available environment variables are:
BIND_PORTThe port you wish to run the container on, defaults to 9170
ORGSThe docker hub organizations you wish to monitor, expected in the format "org1, org2" (Also works for users)
IMAGESThe images you wish to monitor, expected in the format "user/image1, user/image2". Can be across different dockerhub users.
Below is a list of the available flags. You can also find this list by using the
imagesImages you wish to monitor: expected format 'user/image1,user/image2'
listen-addressAddress on which to expose metrics and web interface. (default ":9170")
organisationsOrganisations/Users you wish to monitor: expected format 'org1,org2'
telemetry-pathPath under which to expose metrics. (default "/metrics")
Install and deploy
Run manually from Docker Hub:
docker run -d --restart=always -p 9170:9170 infinityworks/docker-hub-exporter -listen-address=:9170 -images="infinityworks/ranch-eye,infinityworks/prom-conf" -organisations="super6awspoc"
Build a docker image:
docker build -t <image-name> . docker run -d --restart=always -p 9170:9170 <image-name> -listen-address=:9170 -images="infinityworks/ranch-eye,infinityworks/prom-conf" -organisations="super6awspoc"
Currently there is a known issue with this build where if you provide a image or list of images belonging to an organisation that has also been passed into the application then Prometheus will error during metrics gathering reporting that the metric was already collected with the same name and labels.
Metrics will be made available on port 8080 by default
An example of these metrics can be found in the
METRICS.md markdown file in the root of this repository
