Cone.png This article or section is a stub. Stubs are articles that have not yet received substantial attention from the authors. They are short or insufficient pieces of information and require additions to further increase the article's usefulness. The project values stubs as useful first steps toward complete articles.


Installing the linode CLI:

pip3 install linode-cli
linode-cli configure --token
linode-cli --json --pretty domains list


Example Perl code using LWP to update an A record:

# Set up a user agent with our token as default header
$ua = LWP::UserAgent->new();
$ua->default_header(
	'Content-Type'  => "application/json",
	'Authorization' => "Bearer $dnsApiKey"
);

# Find the ID of the domain
$json = $ua->get( 'https://api.linode.com/v4/domains' )->content;
for ( @{ decode_json( $json )->{data} } ) {
	$domain_id = $_->{id} if $_->{domain} eq $domain;
}
die "Domain name not found" unless $domain_id;

# Find the ID of the A record having the host name
$json = $ua->get( "https://api.linode.com/v4/domains/$domain_id/records" )->content;
for ( @{ decode_json( $json )->{data} } ) {
	$record_id = $_->{id} if $_->{name} eq $host;
}
die "Host name not found" unless $record_id;

# Update the A record
$ua->put(
	"https://api.linode.com/v4/domains/$domain_id/records/$record_id",
	'Content' => encode_json({ 'target' => $new_IP })
);
