Configuring
ECH ECE
In order for ecctl to be able to communicate with the RESTful API, it needs to have a set of configuration parameters defined. These parameters can be set in a configuration file, through environment variables, or at runtime using the CLI's global flags.
The hierarchy for configuration parameters is as follows, from higher precedence to lower:
- Command line flags 
--api-key,--region,--verbose - Environment variables
 - Shared configuration file 
$HOME/.ecctl/config.<json|toml|yaml|hcl> 
If it's your first time using ecctl, use the init command to assist you in generating a configuration file. The resulting configuration file will be saved under ~/.ecctl/config.json:
$ ecctl init
