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
