It is possible to use the NordVPN Linux CLI app within a Docker container.
In order to do that, you have to use the following NordVPN Dockerfile configuration to set up your Docker container:
FROM ubuntu:18.04 ARG VERSION=3.7.4 RUN apt update && \ apt install -y wget && \ wget -O /tmp/nordrepo.deb https://repo.nordvpn.com/deb/nordvpn/debian/pool/main/nordvpn-release_1.0.0_all.deb && \ apt install -y /tmp/nordrepo.deb && \ apt update && \ apt install -y nordvpn=$VERSION && \ apt remove -y wget nordvpn-release ENTRYPOINT ["/usr/sbin/nordvpnd", "&"]
For more detailed information on how to use Docker, check the Docker documentation.
After that, you can use the native NordVPN commands following this tutorial.
