# Sample commands to show how to use the Go SDK for Pydio Cells

Pydio Cells comes with a powerful REST API that exposes various endpoints and enable management of a running Cells instance.
As a convenience, the Pydio team also provide a ready to use SDK for the Go language that encapsulates the boiling code to wire things 
and provides a few chosen utilitary methods to ease implemantation when using the SDK in various Go programs.

The children commands defined here show some basic examples of what can be achieved when combining the use of this SDK with 
the powerful Cobra framework to easily implement small CLI client applications.

ExampleCmd is the parent of all example commands defined in this package. It takes care of the pre-configuration of the defaut connection to the SDK in its PersistentPreRun phase.

Functions

func SetUpEnvironment

func SetUpEnvironment(configFilePath string, s3ConfigFilePath ...string) error

SetUpEnvironment retrieves parameters and stores them in the DefaultConfig of the SDK. configFilePath and s3ConfigFilePath can be <nil> if the parameters are defined via env variables.
