To run the image with docker use the following command:

    docker run -d \
    -e NOIP_USER=<Your No-IP username or email>
    -e NOIP_PASSWORD=<Your No-IP password> \
    -e NOIP_HOST=<Your No-IP host-name you want to update> \
    -e NOIP_INTERVAL=<The update interval (default: 60 minutes)> \
    papela/noip-updater:latest

To be able to use the image on an armx64 processor, use the image: papela/noip-updater:armx64latest

For logging purposes you would want to set the correct time in the container. We link both timezone and localtime to the docker container as such:

    -v /etc/timezone:/etc/timezone:ro 
    -v /etc/localtime:/etc/localtime:ro 

You can also download the script file and modify it yourself then run outside of Docker. The only dependencies required are: curl and sleep (most Linux distros have these preinstalled)

What this does is:

1. Check if you variables are set except for NOIP_INTERVAL since this has been set at 60 minutes by default (If the time is equal to or less than 0, it will only be executed once and then exit).
2. It uses curl to update the given No-IP host-name.
3. It sleeps for the given interval (as long as it is not 0) and then starts at step 2 again.
