Netcup configuration

You need to create two dns entries beforehand:

Host	Type	Destination
vpn	AAAA	IPv6
vpn	A	IPv4
ddns	AAAA	IPv6
ddns	A	IPv4

vpn.example.com -> the domain that gets updated

ddns.example.com -> the domain your Fritz!Box calls for updates

Container configuration

Create compose.yml and config in your app directory i.e.:

mkdir -p /opt/docker/owndyndns
cd /opt/docker/owndyndns

# Create docker-compose.yml and copy the contents from repository file
vi compose.yml

# Create config, copy the contents from repository example.config and change the parameters
vi config

# Start the Container with
docker compose up -d
