- running in privileged mode
- mounted /dev into /host/dev
- mounted directory for the mounts in shared mode
- required environment variables are filled

# docker run -ti --privileged -v /dev:/dev:rw -v /mnt:/mnt:shared -e DO_TOKEN=<YOUR DIGITAL OCEAN TOKEN> remora- DO_TOKEN - Digital Ocean API token with write permissions
