You can define the env file "dns_resolv_env.json" as follows:
``` ```
{ {
"auth_key": "key here (required without --auth)", "auth_key": "key here",
"zone_id": "zone id here (optional)", "zone_id": "zone id here",
"default_name": "website name here (optional)" "default_name": "website name here"
} }
