From 6533c14997700f74e9ea42121303fc1f5c63e62b Mon Sep 17 00:00:00 2001 From: Helmut Grohne Date: Wed, 15 May 2024 07:21:53 +0200 Subject: network: configure a tun host0 interface in a container While containers often have their host0 network provided by veth when the container runtime is privileged, unprivileged containers tend to have their network provided via slirp4netns or pasta. These tools use a tun interface rather than a veth interface and systemd should still set configure such networks. We should have different .network files for the veth and tun use cases as there may arise a need to configure them differently. We should not rename 80-container-host0.network as that would cause existing drop-ins to no longer apply. Closes: #32095 Fixes: f139393dd20a ("network: use Kind= instead of Driver=") Signed-off-by: Helmut Grohne --- network/80-container-host0-tun.network | 22 ++++++++++++++++++++++ network/meson.build | 1 + 2 files changed, 23 insertions(+) create mode 100644 network/80-container-host0-tun.network (limited to 'network') diff --git a/network/80-container-host0-tun.network b/network/80-container-host0-tun.network new file mode 100644 index 0000000000..1a50512d83 --- /dev/null +++ b/network/80-container-host0-tun.network @@ -0,0 +1,22 @@ +# SPDX-License-Identifier: MIT-0 +# +# This config file is installed as part of systemd. +# It may be freely copied and edited (following the MIT No Attribution license). +# +# To make local modifications, use "networkctl edit".
