Create a docker container for updating a TransIP DNS record with the current public IP address.
It monitors the current public IP address and when it changes it updates the DNS record hosted at TransIP.
It does this every 4:30 to 5:00 minutes to make sure the DNS record is always up-to-date.

This project uses:

• IPInfo.io API for getting the public IP address
• transip/tipctl TransIP Control the official TransIP RestAPI CLI for setting the IP address
• php:cli-alpine Official php:cli-alpine docker image

1. Put your private key in a file called private.key and store it next to the docker-compose.yml file.
2. Add the tipddns service to your docker-compose.yml file and change the LOGINNAME and DOMAINS environment variables.
3. Run docker compose up -d to start the container.

services:
  tipddns:
    container_name: tipddns
    image: bvandevliet/tipddns:latest
    restart: unless-stopped
    volumes:
      - ./private.key:/app/private.key:ro
    environment:
      TZ: Europe/Amsterdam
      LOGINNAME: myusername
      DOMAINS: mydomain.com,myotherdomain.com
      ALWAYSLOG: true
