Dnscontrol is a tool to synchronize your DNS to multiple providers from a simple DSL.
Installation
Install dnscontrol in your current environment
# nix-env -iA nixos.dnscontrol
Configuration
In the following example usage, we'll create a credentials file called creds.json with the login details for the domain provider Inwx.com:
creds.json
{
"inwx": {
"TYPE": "INWX",
"username": "myuser",
"password": "mypassword"
}
}
See upstream documentation for available provider and their authentication syntax.
The second required configuration file called dnsconfig.js defines providers and domain configurations. In this example, we'll add a subdomain test to the domain example.org with a specific A-record.
dnsconfig.js
var REG_NONE = NewRegistrar("none");
var DSP_INWX = NewDnsProvider("inwx");
D("example.org", REG_NONE, DnsProvider(DSP_INWX), NO_PURGE,
A("test", "1.2.3.4")
);
The provider will be Inwx for which we configured the credentials earlier. The option NO_PURGE tells dnscontrol to only add the new record while leaving all other entries untouched.
Usage
Preview the changes which will be made to your domain
# dnscontrol preview
Apply changes with the following command
# dnscontrol push
Confirm changes to the dns record using the tool dig.
# nix shell nixpkgs#dnsutils --command dig +short test.example.org
