DNS DIG Action

Provided by: "Apache Software Foundation"

Support Level for this Kamelet is: "Stable"

Query a DNS through Dig

The Kamelet expects the following headers to be set:

domain-name / ce-domainname: as the domain for which we are querying the DNS
dns-type / ce-dnstype: as the DNS type

If the domain-name header won’t be set the body will be used as domain name.

If the dns-type header won’t be set, the DNS Type A will be used.

Configuration Options

The dns-dig-action Kamelet does not specify any configuration options.
