Load Balancer Environment Variables

This page contains all environment variables, which can be specified to configure the Load Balancer controller of hcloud-cloud-controller-manager.

Some environment variables define global defaults. These defaults can be overridden by setting the corresponding annotation. If you remove such an annotation while a global default is configured, the global default will be applied again.

  • Enums are depicted in the Type column and possible options are separated via the pipe symbol |.
  • The duration type is a Go duration string, i.e. a sequence of decimal numbers each with a unit suffix such as 300ms, 30s, 5m or 1h (see time.ParseDuration).
