Container Instance

$ docker run -d christiantragesser/dnsexit-ip-update -domains <dnsexit domain> -key <API key>

Options

Multiple DNSExit Domains
Multiple DNSExit registered domains can be managed by the same A record information by providing a comma deliniated list of hostnames for the domains value.

$ dnsexit -domains my-site.com,your-site.io,our-site.net -key <API key>

Check Interval
By default, IP update checks happen in 10 minute intervals.
This cadence can be changed by using the -interval flag with a value of the desired interval in minutes.

$ dnsexit -domains <dnsexit domain> -key <API key> -interval 20

The interval value can also be configured by setting the environment variable CHECK_INTERVAL.

Preferred IP Address
By default, the client configures DNS A record updates using a discovered egress IP address.
Use the -ip flag with a desired IP address to override the discovered IP address value.

$ dnsexit -domain <dnsexit domain> -key <API key> -ip 1.1.1.1

The ip value can also be configured by setting the environment variable IP_ADDR.
