S3 exporter

A simple exporter for S3-compatible buckets that will export metrics partitioned by Kubermatic cluster names.

It assumes all objects belonging to a given cluster have a prefix of ${CLUSTERNAME}-.

Usage:

Usage of ./s3-exporter:
  -access-key-id string
        S3 Access key, defaults to the ACCESS_KEY_ID environment variable
  -address string
        The port to listen on (default ":9340")
  -bucket string
        The bucket to monitor (default "kubermatic-etcd-backups")
  -ca-bundle string
        Filename of the CA bundle to use (if not given, default system certificates are used)
  -endpoint string
        The s3 endpoint, e.G. https://my-s3.com:9000
  -kubeconfig string
        Path to a kubeconfig. Only required if out-of-cluster.
  -log-debug
        Enable more verbose logging
  -log-format value
        Use one of [JSON, Console] to change the log output format (default JSON)
  -secret-access-key string
        S3 Secret Access Key, defaults to the SECRET_ACCESS_KEY evnironment variable
