NetBird

add-netbird-lxc.sh gives an existing container access to /dev/net/tun and installs NetBird inside it. It does not connect the container to a NetBird network.

What it changesCopy Anchor Link

On the host:

• Starts the container if it is not running and waits until pct status reports running.

• Appends two lines to /etc/pve/lxc/<CTID>.conf:

  Copy Text

  lxc.cgroup2.devices.allow: c 10:200 rwm
  lxc.mount.entry: /dev/net/tun dev/net/tun none bind,create=file

Inside the container:

• Installs curl if missing, plus ca-certificates and gpg.
• Removes the old /usr/share/keyrings/netbird-archive-keyring.gpg and adds the https://pkgs.netbird.io/debian repository (suite stable, component main) with setup_deb822_repo.
• Installs the netbird-ui package.
• If the container has a docker.service unit, writes /etc/systemd/system/netbird.service.d/after-docker.conf so NetBird starts after Docker (After=docker.service, Wants=docker.service).

No credentials are created.

After the installCopy Anchor Link

Reboot the container so the new device entries apply, then run inside it:

netbird up

UpdateCopy Anchor Link

The script has no update path and installs no update_ helper. NetBird comes from an APT repository, so apt inside the container updates it.

RemoveCopy Anchor Link

The script has no uninstall path. Remove the package inside the container and delete the two lines from the container configuration by hand.

LimitsCopy Anchor Link

• The two configuration lines are appended without checking whether they already exist. Running the script twice against the same container leaves duplicate entries in /etc/pve/lxc/<CTID>.conf.
• The container list has no cancel branch: cancelling the dialog ends the script through its error handler.
• Only LXC containers on the node you run it on are listed.
