SOURCE_URL	Base URL of your prometheus service	string	https://prometheus.local
SOURCE_BUCKET	Bucket for your source if using object based storage	string	bucket_name
SOURCE_USERNAME	Username to access your source	string	admin
SOURCE_PASSWORD	Password to access your source	string	password

LOG_LEVEL	Logging level to run on	string	info

EVAL_PERIOD_SECONDS	If set, the minio source type will only trim blocks that has data within this many seconds of your retention periods. -1 will search all data. This should be some multiple of the frequency you run the process	num	1814400

Building the image

This image is built using multi-platform images. To do so, you need a custom builder (run this once)

docker run --rm --privileged docker/binfmt:a7996909642ee92942dcd6cff44b9b95f08dad64
docker buildx create --name mybuilder
docker buildx use mybuilder
docker buildx inspect --bootstrap

After you have a custom builder, you can build as necessary:

export VERSION=
docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v7 --push -t mystik738/prometheus-retention:latest -t mystik738/prometheus-retention:${VERSION} .
