duckdns

Golang client for updating DNS entries at https://duckdns.org

Usage

Usage of ./duckdns:
  -c, --config string       Config file location (default "duckdns.yaml")
  -d, --debug               Use debug mode
  -n, --names stringSlice   Names to update with DuckDNS. Just the subdomain section. Use the flag multiple times to set multiple values.
  -t, --token string        Token for updating DuckDNS
  -l, --log string          Log file path. If unset default to `stderr`

Modes

Preference for items is in the following order:

• CLI
• Environmental,
• Configuration File

If items are only partially complete, extra methods will be used to try and complete the needed values. If you only set the token on the CLI the name values will attempt be be filled from the environment variables, and finally the configuration file. This is also a useful strategy for overriding items that are set lower in the order of priority. Use the CLI for your names, and rely on the token from the configuration file.

CLI Only

Pass all of the arguments in via CLI

duckdns -t <your token> -n name1 -n name2

Environment Variables

export DUCK_TOKEN="<your token>"
export DUCK_NAMES="name1 name2" #use space delimited names
duckdns

Configuration File

duckdns.yaml

---
token: feedfeed-feed-feed-feed-feedfeedfeed
domains:
  - testdomain
  - test-domain

duckdns # uses duckdns.yaml in the same directory as the default
# or
duckdns -c /path/to/duckdns.yaml

Note: This does not currently allow for specification of an IP address. The address that is observed by DuckDNS is what is used.
