⁠using docker-compose and docker secrets

In case you plan to commit your docker-compose files to repos and wish to keep tokens/domains secure

version: "3"
services:
  testduckdns:
    image: ghcr.io/anujdatar/duckdns
    container_name: duckdns
    restart: unless-stopped
    environment:
      - SUBDOMAINS_FILE=/run/secrets/duckdns_subdomains
      - TOKEN_FILE=/run/secrets/duckdns_token
      - TZ=America/New_York
      - FREQUENCY=1  # OPTIONAL, default is 5
    secrets:
      - duckdns_subdomains
      - duckdns_token

secrets:
  duckdns_subdomains:
    file: duckdns_subdomains.txt
  duckdns_token:
    file: duckdns_token.txt

Your secret files should just be plain text strings containing subdomains/tokens

⁠duckdns_subdomains.txt
subdomain1,subdomain2
