Dynamic DNS

If you don't have a static IP you still can use your dynamic's one. Providers like cloudflare allow you to do it without any supplementary charges. Thanks to David Schlachter for guidance:

Server side client setup

You'll need a server side client to notify your DynDNS provider for any change. Create a config folder that can hold your DDclient configuration file and add it the provided configuration file:

• Dockerfiles/ddclient/files/ddclient.conf

Change the configuration file access:

sudo chown root:root ddclient.conf
sudo chmod 400 ddclient.conf

Creating the DDclient image

docker build \
    -t ddclient:latest \
    ./Dockerfiles/ddclient

Creating the containers

docker run -dit \
    --mount type=bind,source="$(pwd)"/config,target=/root/config,readonly \
    --name ddclient ddclient:latest

** Remember, you need to create your container from the repository containing your config/ folder.
