README

docker-cleaner

One more docker cleaner for docker daemon. This tool working like docker system prune -a with prometheus metrics.

Usage patterns

• build agents
• docker hosts with many deploys

        Cleaner check interval (default 15s)
  -docker.dir string
        Docker storage directory (default "/var/lib/docker")
  -docker.threshold float
        Docker volume usage threshold (default 50)
  -docker.ttl duration
        Docker volumes TTL. Same until=48h (default 48h0m0s)
  -exporter.host string
        Docker cleaner exporter listen host (default "0.0.0.0")
  -exporter.port int
        Docker cleaner exporter listen port (default 9203)
  -exporter.telemetry-path string
        Docker cleaner exporter path under which to expose metrics. (default "/metrics")
  -exporter.timeout duration
        Docker cleaner exporter timeout (default 15s)
