Dockerfile build for remote_storage_adapter

A Prometheus storage drive to store data into external TSDB, this will replace built in TSDB from Prometheus. This image is based on golang:alpine as builder to compile the remote_storage_adapter from source code and using image scratch as main image to reduce image size.

This is a write adapter that receives samples via Prometheus's remote write protocol and stores them in Graphite, InfluxDB, or OpenTSDB. It is meant as a replacement for the built-in specific remote storage implementations that have been removed from Prometheus.

For InfluxDB, this binary is also a read adapter that supports reading back data through Prometheus via Prometheus's remote read protocol.

OpenTSDB example:

./remote_storage_adapter --opentsdb-url=http://localhost:8081/

InfluxDB example:

./remote_storage_adapter --influxdb-url=http://localhost:8086/ --influxdb.database=prometheus --influxdb.retention-policy=autogen

To show all flags:

./remote_storage_adapter -h

Configuring Prometheus

To configure Prometheus to send samples to this binary, add the following to your prometheus.yml:

yaml
# Remote write configuration (for Graphite, OpenTSDB, or InfluxDB).
remote_write:
  - url: "http://localhost:9201/write"

# Remote read configuration (for InfluxDB only at the moment).
remote_read:
  - url: "http://localhost:9201/read"

Testing the container

To test whether image working, you can run:

sh
docker container run -d --rm -p 9201:9201 remote_storage_adapter
curl localhost:9201/metrics

You should see the output like:
