Command-line options

Contributors juliantap netapp-rlithman

Astra Trident exposes several command-line options for the Trident orchestrator. You can use these options to modify your deployment.

Logging

  • -debug: Enables debugging output.

  • -loglevel <level>: Sets the logging level (debug, info, warn, error, fatal). Defaults to info.

Kubernetes

  • -k8s_pod: Use this option or -k8s_api_server to enable Kubernetes support. Setting this causes Trident to use its containing pod's Kubernetes service account credentials to contact the API server. This only works when Trident runs as a pod in a Kubernetes cluster with service accounts enabled.

  • -k8s_api_server <insecure-address:insecure-port>: Use this option or -k8s_pod to enable Kubernetes support. When specified, Trident connects to the Kubernetes API server using the provided insecure address and port. This allows Trident to be deployed outside of a pod; however, it only supports insecure connections to the API server. To connect securely, deploy Trident in a pod with the -k8s_pod option.

  • -k8s_config_path <file>: Required; you must specify this path to a KubeConfig file.

Docker

  • -volume_driver <name>: Driver name used when registering the Docker plugin. Defaults to netapp.

  • -driver_port <port-number>: Listen on this port rather than a UNIX domain socket.

  • -config <file>: Required; you must specify this path to a backend configuration file.

REST

  • -address <ip-or-host>: Specifies the address on which Trident's REST server should listen. Defaults to localhost. When listening on localhost and running inside a Kubernetes pod, the REST interface isn't directly accessible from outside the pod. Use -address "" to make the REST interface accessible from the pod IP address.

Caution Trident REST interface can be configured to listen and serve at 127.0.0.1 (for IPv4) or [::1] (for IPv6) only.
  • -port <port-number>: Specifies the port on which Trident's REST server should listen. Defaults to 8000.

  • -rest: Enables the REST interface. Defaults to true.
