WIP

Docker Images

Docker Images are automatically built for AMD64 and ARM architectures and published on Docker Hub.

# "latest" tag is automatically updated for latest release
docker run --rm mkoetter/netbox-dns-zone:latest --help

# "edge" tag is automtically updated for each change in master
docker run --rm mkoetter/netbox-dns-zone:edge --help

Development

python3 -m venv venv/
source venv/bin/activate
pip3 install -r requirements.txt

Examples

Generate a forward zone

python3 dns-zone.py generate --zone=example.com --parent-prefix=10.0.0.0/24 --nameserver=hadron --nameserver=axion
