docker run -d \

ghcr.io/hentra/dyndns-netcup-go
The environment variable INTERVAL
defines the interval of DNS updates in
seconds.
cd
to the file you downloaded and unzipdyndns-netcup-go
somewhere in your pathFirst, install Go as recommended. After that run following commands:

to config.yml
and fill out all the fields. There are some comments in the file for further information. dyndns-netcup-go -v
in the same directory as your configuration file and it will
configure your DNS Records. You can specify the location of the
configuration file with the -c
or -config
flag if you don't want to run
it in the same directory. To disable the output for information remove the -v
flag. You will
still get the output from errors.It might be necessary to run this program every few minutes. That interval depends on how you configured your TTL.
For a list of all available command line flags run dyndns-netcup-go -h
.
Without the cache the application would lookup its ip addresses and fetch the DNS records from netcup. After that it will compare the specified hosts in the DNS records with the current ip addresses and update if necessary.
As reported in this issue it would be also possible to store the ip addresses between two runs of the application and only fetch DNS records from netcup when they differ.
To enable the cache configure the two variables IP-CACHE
and
IP-CACHE-LOCATION
as according to the comments in example.yml
.
