Twingate linux client installation in a Docker container

Installation
1

Hi everyone,

Did somebody tried and manage to install the Twingate Linux client from a Docker container ?

I would like some resources inside a container to be able to access a private resource: the idea was to install the linux client in headless mode, using a service account from within the container.

While everything is working perfect on a standard Ubuntu host, the installation process inside a container gets me stuck:

  • Using ubuntu:20.04 image, :white_check_mark:
  • Installing needed dependencies :white_check_mark:
  • Installing twingate linux client :white_check_mark:
  • Setting up twingate linux client in headless mode :white_check_mark:
  • Starting tinwgate linux client :x:

The client never starts correctly. Here are the logs :

And I don’t manage to get neither systemd-resolved nor NetworkManager services properly enabled/configured. Any help or experience would be very appreciated! :slightly_smiling_face:

Hi @maximebn, did you pass the argument --device /dev/net/tun --cap-add NET_ADMIN in the docker run command?

[2022-10-10T20:48:31.131649+0000] [ERROR] [client] linux_tun_new: No such file or directory: opening /dev/net/tun

The above log sounds like it might not have been set.

Hi @aaron,

Indeed, I did not do it, and I feel a bit ashamed to have missed out this part of documentation :see_no_evil:

I am really sorry, anyway everything is working fine, thank you so much !!
