Install issue with Docker (compose) on QNAP NAS

Hello,

I am trying to install ZeroTier on my QNAP. I’m aware that there’s a specific QNAP package, however I use Docker for everything and if possible I’d like to try and get ZT working with Docker as well.

Error:

zerotier_1 | WARNING: unable to write to file: /var/lib/zerotier-one/identity.secret (unable to open)

zerotier_1 | WARNING: unable to write to file: /var/lib/zerotier-one/identity.public (unable to open)

zerotier_1 | ERROR: unable to configure virtual network port: could not open TUN/TAP device: No such file or directory

The first part of the instructions on the ZT documentation ask me to install QVPN, which I have done.

Otherwise, here’s my docker compose file:

Can anyone assist?
