The base of this script was modified from blaize/docker-dynamic-dns. The implementation was outdated for DuckDNS so I rewrote the shell script based on information documented at DuckDNS specs page and compiled for multiple architectures.
WARNING: This script also does an IPv6 check before each update to DuckDNS. You might get throttled if your interval is set too low. A failure message will appear if your connection does not support IPv6 but the container will continue to update any domains IPv4 address.
There are 5 environment variables for configuration. Bold items are required.
